    A Coherent Methodology for Productivity Analysis Employing Integrated Partial Efficiency1996In: International Journal of Production Economics, ISSN 0925-5273, Vol. 46-47, 401-411 p.Article in journal (Refereed)
    Abstract [en]

    An activity decomposition methodology with theoretical foundation in the principles of activity control and stated focus of interest in the enterprise value-chain is presented. Characteristics of inputs and outputs are discussed, where a set of non-transformable inputs are defined and motivated. An integrated partial efficiency measure is formulated, compensating for some weaknesses of the Debreu-Farrell technical efficiency concept. Providing a coherent basis for productivity analysis, the IPE approach poses an alternative to e.g. DEA especially in the case of multi-level systems and sparse data. The method is easily communicable in terms of measurement and analysis, and may be extended to complement economic performance assessments and benchmarks.

    An MCDM Framework for Dynamic Systems1996In: International Journal of Production Economics, ISSN 0925-5273, Vol. 45, no 1-3, 279-292 p.Article in journal (Refereed)
    Abstract [en]

    A multi-criteria formulation for continuous and discrete-time dynamic systems is presented. The fundamental problem in the design of dynamic systems is the trade-off between response speed (e.g., the time to reach final value and the raise time) and response smoothness (e.g., the overshoot, the undershoot, and the transient dampening). Separate optimisation of criteria is impossible, thus the problem is inherently multiobjective. In a general dynamic system, this is accomplished by adjusting a number of technical parameters in accordance with some ad hoc practice. Previous multi-criteria approaches have been modelled as weighted sums of criteria, with shortcomings in terms of sensitivity analysis and preference articulation. The proposed framework enables the decision maker to design a most preferred system, with full knowledge of local trade-off ratios in terms of chosen criteria. Combining analytical techniques with simulation, the formulation makes the optimisation process transparent to the decision maker, working entirely in decision space. The framework is demonstrated on a dynamic production-inventory model.

    Beslutsprocess för sourcingbeslut2006Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    It seems like outsourcing often does not live up to the expected results. Furthermore, sourcing decisions are often unplanned and improvised based upon insufficient short term foundation. Poor basis for sourcing decisions can lead to that some important factors, which can result in long term consequences, could get overlooked in the decision foundation.

    The purpose of the master thesis is to create a structured decision process that could lead to a well balanced sourcing decision and apply this at Husqvarna AB.

    The method used is a case study which includes a theoretical and an empirical study.

    The decision process is based upon the theoretical framework and is structured as a number of activities. Each activity includes a number of questions that should be answered if a well balanced sourcing decision is to be made. The questions are developed so that they include all the factors that could be affected by outsourcing.

    The case at Husqvarna AB was analyzed and evaluated by using the theoretical decision process. This showed how the decision process can be used by Husqvarna AB.

    The conclusion of the thesis is that the purpose was fulfilled since a decision process was developed that could be applied at Husqvarna AB.

    Införande av Lean Administration i utfallsprovsprocessen2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis concerns implementation of Lean Administration within administrative support-processes. The thesis examines how tools of Lean can contribute to the standardizing of documents and the handling of documents in order to eliminate waste. In addition, quality assurance and higher efficiency are obtained while it is possible to reach a higher capacity for value-adding activities. The empirical findings are based on action research conducted at a trading company where the supporting handling of documents concerning initial samples was studied closely.

    The background to this study can be traced to the increased global competition which has brought more companies to work with improvements to a larger extent. More companies have also decided to outsource parts of their operations to be able to focus on their core competencies. As an effect of this trend, different new actors have specialized in other areas than production. When there is no production to make more efficient, these companies have directed their work with improvements to other areas, such as the administration.

    The purpose with this thesis is to; based on Lean Administration, give suggestions for a new handling system of documents concerning the support processes for initial samples. The result of this work culminates into a proposal which is presented as a template created in Excel. The template has been created during the work with the thesis and it is built with support from principles and tools from Lean Administration. The Excel template is made to replace current documents in the specific administrative process and by doing that, contribute to standardization and increased efficiency to the work with initial samples. The template also creates options to treat customers’ different needs and it also increases quality through a built-in fail proofing feature.

    The template can be considered to be generalized and possible to implement at different companies working with initial samples. However, it may be required to change the graphical layout to company-specific needs.

    Towards the end of the writing process thoughts about developing the Excel template to a total quality document was raised. This document could contain all information concerning quality for a specific article. This idea gives opportunity for further work.

    Suggestions for further research within Lean Administration are given since there is still a lot to investigate within the field. The way the research was conducted, by viewing the work processes with Lean-glasses, can be generalized and applied to other areas than the processes concerning initial samples.

    Manual Assembly Improvement In Make to Order Production2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Manual assembly systems are widely used for producing customized products in make to order production. Despite their competitive advantages, manual assembly systems bring several problems to the production organizations. Early identification of problems on the production floor is very important in order to keep production processes running smoothly and efficient. Hence, this research aims to increase the knowledge of understanding problems related to manual assembly systems in make to order production and develop solutions for the problems. To be able to reach the research aim, two research questions were formulated. While, the first question investigates the problems related to manual assembly systems in make to order production, the second question aims to develop possible solutions for the problems.

    To be able to investigate the research problem in a real-life context, a single case study was performed at Volvo Powertrain F-Plant in Skövde, Sweden where there is a manual assembly of heavy duty diesel engine variants. In addition, existing literature was also investigated to make connections between the theory and the practice. As a result, the problems were revealed under six main categories as assembly processes, assembly operator learning, material handling, layout, ergonomics and information system. After revealing the problems, solutions were developed for each problem by using lean production principles and lean tools such as value stream mapping, standardized work. Moreover, other methods such as implementing kitting system, eliminating 7 waste in the production and implementing Takt time were also used to develop solutions. Based on the value stream mapping at the case company, improvements were developed and future state map was created for the case company. Evidently, the theoretical framework and the results from the empirical work were supported each other. At the end of the research, both research questions were answered and the aim of the research has been reached successfully.

    The results of the research could be used as a guide for production organizations with similar production systems in order to identify and eliminate problems in manual assembly systems in make to order production. In addition, this study could be a basis to investigate the problems and their solutions in manual assembly systems in make to order production. The problems and solutions in manual assembly systems in make to order production could be extended by applying new theories and methods in the research area as a further research.

    Material Handling System Design: A Case-Study in Bosch Rexroth Japan2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In today’s fierce competitive global markets, customers are demanding adjustable lot sizes, shorter lead times, higher quality and flexibility; in short, they want it all. In order to stay competitive in the market, companies need to attain both customer satisfaction and cost reduction in production operations. Material Handling Systems (MHS) is the place to accomplish this goal, since they have a direct impact on production. Therefore, the aim of this study was to design an in-house MHS that could be efficient for the production it serves.

    With this intention, a case-study has been conducted in Bosch Rexroth Japan. During the study, the information gathered through various sources; interviews, observations and measurements. Further, the gathered data is evaluated according to main pillars of the theoretical framework, which includes design principles and physical elements, information and software, human and management.

    By analyzing the findings from literature review and empirical study, first problems and challenges related to MHSs are identified. Thereafter, possible features that the system should posses are elicited and a design is built out of the selected features.

    To conclude, the results show that the success is not solely depending on system’s physical attributes; on the contrary, it is more related to rapid and accurate information sharing within the system. Another vital element is the interaction between system and the people, who are utilizing and operating the system. In general terms, the research took MHS design problems from one-dimensional equipment selection processes and enriches them by adding information sharing, human and management angles to design steps.

    Exploring sustainable manufacturing principles and practices2016Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The manufacturing industry remains a critical force in the quest for global sustainability. An increasing number of companies are modifying their operations in favor of more sustainable practices. It is hugely important that manufacturers, irrespective of the subsector they belong to, or their organizational size, implement practices that reduce or eliminate negative environmental, social and economic impacts generated by their manufacturing operations.

    Consequently, scholars have called for additional studies concerning sustainable manufacturing practices, not only to address the paucity of related literature, but also to contribute to practitioners’ understanding of how to incorporate sustainability into their operations. However, apart from expanding the knowledge of sustainable manufacturing practices, it is first key to understand the ground set of values, or principles, behind sustainable manufacturing operations. For that reason, the purpose of this thesis is to contribute to the existing body of knowledge regarding sustainable manufacturing principles and practices.

    The results presented in this thesis are based on three studies: a systematic literature review exploring sustainability principles applicable to manufacturing settings, and two empirical studies addressing sustainable manufacturing practices.

    In general, it is concluded from the literature that there is a little knowledge about sustainability principles from a manufacturing perspective. In relation to the most common sustainable manufacturing practices, it is concluded that these practices mainly refer to energy and material management, and waste management. Similarly, the study of the adherence of sustainable manufacturing practices to sustainable production principles concluded that the principles concerning energy and materials conservation, and waste management were found to create the highest number of practices. Although most manufacturers still engage in reactive sustainable manufacturing practices driven by regulatory and market pressures, some industrial sectors were found to be more prone to develop proactive sustainable manufacturing strategies than others. Furthermore, SMEs were found to lag behind large organizations regarding adherence to sustainable manufacturing principles.

    Sustainable production adoption by surface treatment SMEs: Challenges and enablers2015Conference paper (Other academic)
    Abstract [en]

    The adoption to sustainable production is a continuous but necessary strive for manufacturing operations, including small and medium enterprises, SMEs. Meeting the future needs of the economic, social and environmental dimensions provides challenges for SMEs. In order for these challenges to be met understanding of internal and external enablers is required. Studies focusing on the enablers for sustainability amongst SMEs are rare; hence these companies are important players in the supply chain to focal companies. In order to enhance the understanding of the adoption of sustainable production for the sector surface treatment SMEs, an explorative study has been conducted. In this study, the focus has been placed in the identification and analysis of the challenges and enablers for adoption of sustainable production. Two stages of empirical data collection were undertaken: a focus group session and an online questionnaire. The findings present challenges based on the limitations of the surface treatment process but also where enablers for the social, economic and environmental for meeting those challenges are strongly linked. The results showed that these SMEs face challenges in their way towards sustainable production, mainly due to: low economic profitability, need for improvement in old working procedures, lack of fully understanding regarding environmental legislation, difficulty in ensuring workforce, lack of technology development and resistance towards change. These challenges could be faced through internal and external enablers, where the support of large-size customers and other stakeholders is critical for these SMEs.

    Conceptual sustainable production principles in practice: Do they reflect what companies do?2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 141, 693-701 p.Article in journal (Refereed)
    Abstract [en]

    A common understanding of sustainable production principles and the identification of sustainable manufacturing practices among practitioners are key starting points in studying how manufacturers are making their operations more sustainable. However, there is a lack of insight in the literature connecting conceptual sustainable production principles, and the practices reflecting these principles. Using semi-structured interviews founded on the sustainable production principles posed by the Lowell Center for Sustainable Production, this paper presents an outlook of how companies in different industries carry out manufacturing practices related to the sustainability production principles. Results showed that the majority of sustainable manufacturing practices remain strongly centered on the environmental dimension of sustainability, with the greatest number of practices emanating from principles concerning energy and material conservation, and waste management. Similarly, reactive sustainable manufacturing practices prevailed over proactive sustainable manufacturing practices, as most of the practices aimed to comply with regulatory and market pressures. Quality and environmental management systems were acknowledged as important tools for putting sustainable production principles into practice; while Swedish environmental and social regulations were found to drive sustainable manufacturing practices. This study connects sustainable production principles with sustainable manufacturing practices and opens the way for further studies on a global or sector-specific scale.

    Lagerhantering i framtiden på Aero Materiel AB2011Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In recent years, increasing emphasis has been placed on streamlining the supply chain. Keeping inventory and warehouses is considered to be a waste of resources. It is however difficult to completely eliminate the need for inventory and warehouses in a supply chain. The purpose of warehousing is to provide a service for the customer. By keeping what the customer demands in inventory it is possible to make a quick delivery when a need arises. Warehousing can thus be an important competitive tool.

    The purpose of this bachelor thesis is to analyse possible changes of the warehousing at Aero Materiel in order to increase the capacity of Aero Materiel’s warehousing. Aero Materiel is a wholesale company with an annual turnover that exceeds fifty million SEK. The company sells accessories for hatches and panels, such as hinges, quick access fasteners, bars and cage nuts. Aero Materiel aims to double their turnover and therefore look at ways to increase the capacity of the warehousing in order to meet future needs.

    To achieve the purpose of this thesis, the following questions have been answered.

    • How is warehousing executed today at Aero Materiel and which methods are used at Aero Materiel?
    • Which other methods for warehousing exist that could be suitable for Aero Materiel?
    • In which way could these other methods improve the warehousing at Aero Materiel?

    Interviews and observations have been carried out at Aero Materiel in order to describe the company and its operations, and in order to describe how the warehousing is conducted. Literature on the subject of warehousing has been studied in order to help answer the thesis questions. A time study has been conducted. Two similar companies have been visited with the purpose of identifying other methods for warehousing.

    Aero Materiel handles between 10 and 70 order lines per day. The warehousing personnel perform the following warehousing activities: Receiving, putaway, order picking, packaging and shipping. The warehousing personnel spend more than 50% of their time on order picking and packaging.

    Several areas with potential for improvement at Aero Materiel were identified during the mapping of the warehousing at Aero Materiel and the visits at the two other companies: the variation of order lines from day to day, the time required for packaging, counting of items, transportation during order picking and the weighing of items.

    The variation of order lines from day to day can be reduced by applying different principles of levelling. By lowering the demands for quality it is possible to reduce the time needed for packaging. Order picking can be made easier by investing in some form of automated storage system. The need for weighing articles can be reduced by keeping information of the item’s weight in the ERP-system.

    Ny förbättrad layout vid Stena Stål AB: Kartläggning av plock- och tillverkningsprocesser samt personalens arbetssituation i dagsläget.2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With today`s business world, it is very important to deliver the right product with right quality and quantity at the right time. By ensuring that the staff are happy and have the opportunity to work in a workplace with good structure, the company will be able to reach these parameters and at the same time maximize the efficiency.

    The project has been carried out at Stena Stål AB in Värnamo. The company's main task is to cut, store and deliver production steel and tool steel to processing companies in the surrounding region. Stena Stål AB in Värnamo is one of total 21 companies in the company group Stena Stål. Stena Stål is a part of the Stena corporate group which owns a total of eight different company groups that are spread in about 250 different locations in 14 countries.

    The purpose of this report is to give Stena Stål AB in Värnamo suggestions on how to design a new facility for tool steel. The demands that the company have on the new facility is that it should be able to deliver within 24 hours, it should be characterized by good order and clarity and that the work situation for the employees should be improved. In order to find the best way to reach the purpose and meet the company’s requirements, the following questions were developed:

    1. What is the value added and the necessary non-value added work in the value stream?

    2. How can the layout of the new department be designed according to the requirements above?

    3. How can work and pallet places be designed from the perspective of good order, efficiency and ergonomics?

    By studying how the current situation looks like using timestudies, observations and interviews, the authors have developed spaghetti diagrams and tables. These show that the major problem at the section is that necessary non-value-adding work takes too much time, the staff goes longer distances than than necessary and that the section is largely lacking of orderliness. Through interviews and obsevations it has also emerged that staff often work with ergonomically unsound lifting.

    By trying to eliminate the major problems of today, the authors have come up with a layout suggestion with associated 5S work. By focusing on 5S work as well as remove heavy lifting from production the authors meet the requirements from the company. The result of the final suggestion improves staff's ergonomic situation considerably by using a traverse for all lifting over 16.5 kg. By placing machines and materials in optimal positions and introduce a customized 5S work for the section is the time for an order reduced by 50-78%, and walking distances for the same order have decreased by 28-60%.

    The conclusion is that Stena Stål AB in Värnamo can reach the goals that they have on the new facility if they are willing to use the layout which has been worked out, and assimilate the methods that are described in this report.

    Analys av monteringslinan för luftbehandlingsaggregat (EC)2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    The purpose of the work is to analyze and balance an assembly line at Fläkt Woods in Jönköping. The work is going to answer the questions about today’s throughput time, how much waste that occurs, number of staff at the assembly line, how the supply of material works and possible improvements that can be made at the work stations. The work is also going to give a proposal of improve-ments that can be made.

    The methods used to get the result include observations and measurements, con-versations with technicians and operators and also data from Fläkt Woods’ data-base.

    Large variations in throughput time are measured during the measure period, from 3 hours up to 5 hours and 35 minutes. These variations depend mainly on the time the air handling unit spends between the stations. The identification of the bottleneck was shown that it occurred in the last station in the assembly line. This results in a pressure from the stations behind with a long throughput time as a con-sequence. The largest source of waste is the operators’ waiting time. The measures that have been made show that the operators wait 33.4 % on average of the time available. The number of operators varies from ten to twelve during the measure period. This number of operators is too high in consideration of the high waiting times. It results in difficulties for the operators to move between the stations be-cause every station is fully manned. The supply of larger components for example fans, batteries, rotary heat exchangers and dampers for the air handling units are made by a truck driver. This leads to disorder in the work stations and fixed posi-tions for a number of smaller components and tools go missing.

    The analysis of the result shows that the pressure that occurs in the assembly line results in high throughput time because the units wait a long time between the stations. To eliminate these waiting times, a suction must be created. The difficul-ties for the operators to move between the stations can be solved with a lower number of operators. This makes it easier for the operators to move between the stations and reduce the waiting time for the operators.

    Prognoser på Kinnarps: Utveckling av en prognostiseringsprocess2006Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [sv]

    Detta 20-poängs projekt på D-nivå har genomförts som en fallstudie på Kinnarps AB i syfte att utveckla en prognostiseringsprocess. Processen ska förbättra framförhållningen och underlätta planering på medellång sikt. Efter att undersökt de problem som upplevs på Kinnarps utvecklade vi följande problemformulering:

    Hur ser prognostiseringsarbetet ut på Kinnarps idag?

    Hur bör en generell prognostiseringsprocess utformas?

    Hur kan prognostiseringsprocessen anpassas till Kinnarps?

    En kartläggning av de berörda avdelningarna utfördes för att besvara den första frågan. Kartläggningen genomfördes genom intervjuer av personer på marknads-, produktions-, inköps- och leveranslogistikavdelningen, även återförsäljare intervjuades då de har kontakt med slutkunden och kunskap om marknaden. Flera problem som påträffades kan vara orsakade av Kinnarps korta framförhållning, som överbeläggning i produktionen, hög fyllnadsgrad i lager 5 och lång ledtid. Det finns tecken på brist i kommunikation mellan avdelningarna vilket leder till att alla planerar för att optimera sin egen avdelning och glömmer att se till helheten. Ett ytterliggare problem är att det inte finns en funktion med ansvar för att planera på medellång sikt.

    En litteraturstudie genomfördes för att kunna utveckla en generell prognostiseringsprocess, resultatet blev en cyklisk process som är uppdelad i fyra delprocesser, avvikelseuppföljning, efterfrågeprocessen, prognosförmedling samt processförbättring. För att prognostiseringsprocessen ska överleva och utvecklas anser vi att det bör finnas en prognosansvarig och innan processen kan implementeras måste parametrarna för prognosen bestämmas.

    Den anpassade processen till Kinnarps innehåller samma fyra delprocesser. En diskussion har förts kring vilka parametrar som vore lämpliga som grund till processen. Då Kinnarps inte har någon taktisk framförhållning idag anser vi att de bör börja prognostisera med en horisont på ett år, indelad i kvartalsperioder då den ska uppdateras och utvärderas. Detta är lämpligt då indelningen passar med budgetåret och säsongsvariationerna samt att de med den framförhållningen kan hinna genomföra förändringar i kapacitet. Som underlag till prognosen bör de använda sig av försäljningshistorik från affärssystemet och säljkårsuppfattning från återförsäljare och marknadsexperter. Prognoserna bör göras på en produktmodellnivå, som sedan ska kunna brytas ner på artikelnivå i systemet.

    Prognostiseringsprocessen är ett lämpligt sätt att utveckla samarbetet och integreringen mellan Kinnarps avdelningar då de bör stödja varandra för att förbättra för företaget som helhet. Användandet av en prognostiseringsprocess skulle ge Kinnarps ett bättre underlag för kapacitetsplanering av maskiner och personal i produktionen. Det skulle även kunna ge inköpare bättre förutsättningar vid avtalsförhandling hos leverantörer och bättre leveranssäkerhet. Leveranslogistik skulle kunna planera sina resurser bättre och marknadsavdelningen och återförsäljarna skulle kunna lova sina kunder kortare ledtider vilket skulle ge den konkurrensfördelar.

    A Study of the Effects of Operational Time Variability in Assembly Lines with Linear Walking Workers2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In the present fierce global competition, poor responsiveness, low flexibility to meet the uncertainty of demand, and the low efficiency of traditional assembly lines are adequate motives to persuade manufacturers to adopt highly flexible production tools such as cross-trained workers who move along the assembly line while carrying out their planned jobs at different stations [1]. Cross-trained workers can be applied in various models in assembly lines. A novel model which taken into consideration in many industries nowadays is called the linear walking worker assembly line and employs workers who travel along the line and fully assemble the product from beginning to end [2]. However, these flexible assembly lines consistently endure imbalance in their stations which causes a significant loss in the efficiency of the lines. The operational time variability is one of the main sources of this imbalance [3] and is the focus of this study which investigated the possibility of decreasing the mentioned loss by arranging workers with different variability in a special order in walking worker assembly lines. The problem motivation comes from the literature of unbalanced lines which is focused on bowl phenomenon. Hillier and Boling [4] indicated that unbalancing a line in a bowl shape could reach the optimal production rate and called it bowl phenomenon.

     This study chose a conceptual design proposed by a local automotive company as a case study and a discrete event simulation study as the research method to inspect the questions and hypotheses of this research. 

    The results showed an improvement of about 2.4% in the throughput due to arranging workers in a specific order, which is significant compared to the fixed line one which had 1 to 2 percent improvement. In addition, analysis of the results concluded that having the most improvement requires grouping all low skill workers together. However, the pattern of imbalance is significantly effective in this improvement concerning validity and magnitude.

    Prioritizing improvements at a shopping mall using an IPA framework approach2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this thesis work is to develop a model which can aid in prioritizing which customer service that should be the focus of improvement, using the two parameters; customers’ judgment of importance and the current performance as perceived by the customer. The thesis work examines customer services within a shopping mall In Thailand. To fulfill the purpose, three research questions were stated:

    1. How important is each of the three customer services: safety & security, cleaning operation and guest service according to the customer in a shopping mall in Thailand.
    2. How do Thai customers rank the current performance of the three customer services: safety & security, cleaning operation and guest service in a Thai shopping mall?
    3. How can a model be developed to aid in prioritizing where to focus improvements by combining values of customers’ judgment of importance and current perceived performance of the three customer services?

    Methodology – The gathering of data was done by interviewing and observing personnel of different customer services. This information was then used in creating surveys for the customers of the shopping mall to answer questions regarding the importance and performance of each service. A model was developed based on theories and the data gathered from the case study was used to illustrate its functions.

    Findings – The result of the first two research questions provided data which was used as input in the model created. The model is based on several theories and uses a “percentage of max” value to enable comparison between values. The model limits the “actual improvement” received when suggesting an improvement of a certain percentage by taking different theories into account.

    Implications – The model is made solely based on theories regarding customer satisfaction and performance and should therefore be seen as a guideline for practical use. The model focuses on the relation between importance and performance without any consideration to costs or any other parameters which has to be investigated and taken into consideration by the management team.

    Research limitations – This thesis work has been based around a single case study of a shopping mall in Thailand which could limit its generalization. However the model is solely based on theory and the data from the case study has only been used to test the model. Thus, the model should be applicable for other similar companies as long as the same input data can be gathered. Further studies could be done regarding how costs can be applied to the model as well as how different measurements. For example, the relation between amount of customers and amount of workers can be used in combination with the model.

    Towards a generic design method for reconfigurable manufacturing systems: Analysis and synthesis of current design methods and evaluation of supportive tools2017In: Journal of manufacturing systems, ISSN 0278-6125, E-ISSN 1878-6642, Vol. 42, 179-195 p.Article in journal (Refereed)
    Abstract [en]

    In today's global manufacturing environment, changes are inevitable and something that every manufacturer must respond to and take advantage of, whether it is in regards to technology changes, product changes, or changes in the manufacturing processes. The reconfigurable manufacturing system (RMS) meets this challenge through the ability to rapidly and efficiently change capacity and functionality, which is the reason why it has been widely labelled the manufacturing paradigm of the future. However, design of the RMS represents a significant challenge compared to the design of traditional manufacturing systems, as it should be designed for efficient production of multiple variants, as well as multiple product generations over its lifetime. Thus, critical decisions regarding the degree of scalability and convertibility of the system must be considered in the design phase, which affects the abilities to reconfigure the system in accordance with changes during its operating lifetime. However, in current research it is indicated that conventional manufacturing system design methods do not support the design of an RMS and that a systematic RMS design method is lacking, despite the fact that numerous contributions exist. Moreover, there is currently only limited evidence for the breakthrough of reconfigurability in industry. Therefore, the research presented in this paper aims at synthesizing current contributions into a generic method for RMS design. Initially, currently available design methods for RMS are reviewed, in terms of classifying and comparing their content, structure, and scope, which leads to a synthesis of the reviewed methods into a generic design method. In continuation of this, the paper includes a discussion of practical implications related to carrying out the design, including an identification of potential challenges and an assessment of which tools that can be applied to support the design. Conclusively, further areas for research are indicated, which provides valuable knowledge of how to develop and realize the benefits of reconfigurability in industry.

    Reconfigurable Manufacturing - An Enabler for a Production System Portfolio Approach2016In: Procedia CIRP, 2016, 139-144 p.Conference paper (Refereed)
    Abstract [en]

    The purpose of this paper is to investigate how the development of a strategically integrated product and production system portfolio could be enabled by the concept of reconfigurable manufacturing. In previous research, several critical challenges related to developing production system portfolios have been identified, but it has not been investigated how developing a reconfigurable manufacturing concept could aid some of these. Therefore, through a multiple case study, these critical challenges have been investigated in two companies that have recently developed reconfigurable manufacturing concepts for multiple variants and generations of products. The findings reveal that the companies need to deal with several challenges in order to enable a functioning RMS. By running the project separately from the NPD project and to include several product types and production sites the company overcome several challenges. (C) 2016 The Authors.

    Improving efficiency in material supply to assembly line: A case study in the automotive industry in Southeast Asia2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of the thesis was to improve the material supply for assembly line.

    Methodology - The collected data were conducted through observations and measurements at the case company. Empirical data were analyzed and compared with the theoretical framework.

    Result - Several non-value adding activities were identified in the case study that resulted in 88% of the total working effort. These non-value adding activities were classified into wastes referring to Liker and Meier (2006). Six different wastes were found: excess inventory, unnecessary transportation, unnecessary movements, defected products, waiting, unused and neglected resources. Improvement recommendations were proposed to increase the efficiency of the material supply.

    Conclusions – There is at least one improvement proposal for every identified waste and combinations of these improvement proposals can reduce the non-value adding activities. Methods that can be useful to improve the material supply efficiency are change storage policy, reduce batch size, route plan milk-runs, implement standard work procedures and develop and integrate the information system. 5S and Kaizen are proposed theories that promote continuous improvements of the material supply.

    Research Limitations – Since there are many factors affecting the material supply, more improvement proposals could have been found without delimitation of activities. This thesis is based on a single case study which leads to generalizable results for only companies with similar circumstances.

    Further Research – By implementing the conducted improvement proposals a comparison of non-value adding activities is possible to strengthen the presented methods.Key Words – Material Supply, Lean production, Non-Value Adding Activities, Wastes, Efficiency Improvements.

    Reduktion av leveransledtid för kundorderstyrda produkter: Delivery lead time reduction of customer order products2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Problembakgrund

    Weland AB tillverkar bland annat spiraltrappor. En spiraltrappa består utav flera olika komponenter som i sin tur består av ett flertal detaljer, alla komponenter har ett specifikt materialflöde i tillverkningen. Weland AB tillverkar två olika typer av spiraltrappor, standard- och tillverkningstrappa. Standardtrappans komponenter tillverkas mot lager och följer standardiserade mått med krav på belastning medan tillverkningstrappans komponenter tillverkas mot kundorder. Enligt företagets policy tar det två veckor för en standardtrappa att levereras och åtta veckor för en tillverkningstrappa. En liten förändring av minst en av standardtrappans komponenter medför att leveransledtiden utökas med sex veckor. Idag finns ingen nulägesbeskrivning över kundorderuppfyllelseprocessen för spiraltrapporna, vilket medför att det är svårt för företaget att veta om de angivna leveranstiderna är rimliga att erbjuda kunderna eller om de kan reduceras.

     

    Syfte

    Syftet med projektet var att göra en nulägesanalys över kundorderuppfyllelseprocessen för tillverkningstrappan samt generera förbättringsförslag som kan minska leveransledtiden.

     

    Metod

    Metoden som användes för att kartlägga nuläget var värdeflödesanalys. Metoden medförde att både material- och informationsflödet analyserades i kundorderuppfyllelseprocessen. Data som saknades för att kartlägga nuläget identifierades via observationer i produktionen och samlades in med hjälp av ett ifyllnadsdokument “Informationskortet”. Informationskortet fick följa med en kundorder för en tillverkningstrappa från planering till leverans. Intervjuer och samtal följde sedan för att öka validiteten i resultatet. Efter kartläggningen analyserades nuläget och begränsningsteorin användes för att identifiera förekommande begränsningar i flödet.

     

    Resultat

    Kartläggningen av nuläget åskådliggjorde ett begränsat informationsflöde och visade att företaget saknade ett helhetsperspektiv för spiraltrapporna. Värdeflödesanalysen visade att cirka 1,3 % skapade mervärde för kunden i kundorderuppfyllelseprocessen. Förslag till förbättringar togs sedan fram med hjälp av kartläggningen och nulägesanalysen. Ett av förslagen innebar att dagliga order läggs ut i produktion istället för veckoorder tillsammans med ett dragande system (kanbansystem). Förslaget kompletterades med att introducera ”styrningstavlor” för att erhålla en mer visuell styrning i produktionen. Syftet med förbättringsförslaget var att minska den totala genomloppstiden för komponenterna i produktionen. Det andra förbättringsförslaget innebar att öka kapaciteten på en begränsning med syfte att reducera genomloppstiden i förberedningen. Med de båda förbättringsförslagen kunde en ny teoretisk leveransledtid uppskattas. Leveransledtiden uppskattas kunna minskas från 39 arbetsdagar (åtta veckor) till 10 arbetsdagar för en spiraltrappa som tillverkas mot kundorder.

    Utveckling av metoden kunddrivet inköp: Inkludering av egentillverkade artiklar2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of the study was to develop the CDP-method to include also manufacturing items. In order to help answering the purpose, three questions have been defined:

    1. Which data and analytical tools in the CDP-method affect manufactured items?

    2. Which tools should be added in the second phase in order to analyse manufactured items?

    3. Which additional data should be included in the first phase in order to include manufactured items?

    Method – The procedure for the study contain a literature study, case study and an analytical conceptual approach. In order to answer the first question, a case study was performed with interviews, observations and document studies at Kinnarps, Skillingaryd. The received data were interpret and analysed in relation to the theoretical framework that generated a result. In order to answer the second and third question, an analytical conceptual approach were conducted from previous theories that later was compiled in a model.

    Findings – Step one to four in the first phase and step seven and eight in the second phase of the CDP-method affect manufactured items. A model for included manufactured items has been created where analytical tools and data are presented that should be investigated. The tools that are introduced are based on theories within value stream mapping, material handling and a model for make-or-buy-decision. Based on these tools, it could be interpreted which data that should be created for manufactured items.

    Implications – It appears in this study that no new literature has been created but combinations of already existed theories are presented. The theory within the CDP- method could be changed from results that were founded when the CDP-method was applied at the case company. This is presented in the bachelor thesis seventh chapter. Companies that apply the CDM-method could increase the knowledge for customer driven manufacturing and improve the company internally. The method also assists when analysing both external and internal flows.

    Limitations – Today the CDP-method is relative new and not applied outside the context that it is designed for. One result of this is that the authors have not confirmed these literatures by other researcher. The focus has been to find theories to customer driven manufacturing within value stream mapping material handling and so on. It would have been desirable if additional literature studies could be performed in order to find appropriate development areas.

    Keywords – CDP-method, material handling, SWOT-analysis, supply chain, make- or-buy analysis, value stream mapping, production layout, total cost of ownership.

    Uppföljningsarbetet av efterkalkyler på Portsystem 2000 AB2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    This thesis is carried out at Portsystem 2000 AB who manufactures and markets industrial doors and docking systems. The background to this thesis is that the company’s management considers that their follow-up process of cost accounts is not fully functioning.

    The aim with this report is to investigate and describe the present procedure of the follow-up process concerning the time of operations and come up with suggestions for improvements. This thesis is performed within the range of the following areas: Information systems, quality, processes and cost calculation. The main method we used were semi structured interviews with a fairly opened framework. We also did a small-scale quantitative survey. The results from our investigation are that Portsystem lacks in the following matters:

    • Communication between the parts of the information system

    • Formulated routines for handling of divergence

    • Mapping of causes for divergence

    • Reliability in the information system

    Our conclusions are that Portsystem first of all need to put effort in doing an extensive revision of the present time estimations for the products with existing cost accounts. They should also examine the possibilities of making the enterprise system communicate with the MRP–system. More frequently executed calculations are a way of improving the precision in the cost estimations. We also consider that Portsystem should put effort in examine the distinguishable causes for divergence and take them into account during the follow-up process.

    KOSTNADSKALKYLERING VID VOLYMVARIATION2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose - The purpose is to contribute with knowledge regarding cost calculations during variating lot quantity. To achieve the purpose, it was broken down to two questions that are presented below.

    [1] Which costs can be identified in manufacturing units?

    [2] How should product costing be constructed to handle variety in lot quantity?

    Method and implementations - During the study a case study have been conducted to gather empirical data and a literature study to gather theories. In the case study we used observations, interviews and document study to gather empirical data. Collected empirical data was analyzed against theory to answer the studies questionnaire and through that achieve the purpose.

    Result - The result consists of the identified costs in the studied field and a model for costing that can handle variation in lot quantity. The costs are explained with help of the activity in the production where it arose, which is the result of the first question. To answer the second question, different models for cost accounting have been analyzed to identify their strengths and weaknesses in regard of variating lot quantity. During the analysis different characteristics was identified that cost calculations should include to handle variating lot quantity. These characteristics have formed the developed model and given it the characteristics a model for cost calculations should have when calculating with variating lot quantity. The model was compared with self-costing to make the result clearer.

    Implications - The results implications are both theoretical and practical since the result affects the practice and extend the theories regarding costing with variating lot quantity. The practical implications are the impact on the way cost calculations are performed with variating lot quantity. Unlike the practical implications the theoretical are going both ways as theory have affected the result and the result are affecting the theory. The result is showing that today’s way of cost calculation is deficient when handling variation in lot quantity, which leads to questioning of the established theories and further research is needed for complementing or developing.

    Further research - The reports result is founded on a case study with a single case which lower the results generalizability. Further research to strengthen generalizability can be conducted with a case study that have multiple cases. The result hasn’t been tested in the practice so further research can be performed with practical implementation of the reports result.

    Limitations - The case study was of single case characteristic which mean that one company was studied. To increase the level of generalizability the case study could have been conducted at multiple businesses with different conditions.

    Kartläggning av hälsorisker vid tillverkning av ankel-fot-ortoser2016Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    This thesis is part of a bigger project, ORTO - roughly translated to optimized resource efficient manufacturing of orthoses. During the manufacturing of orthopedic aids many different methods are used to manufacture individually adjusted products. Processes, methods and material may vary depending on what end product is going to be produced. The knowledge of how the manufacturing affects the employees long term is not complete from a health-oriented perspective. The purpose of this thesis is to map out the manufacturing processes for rigid and hinged molded ankle-foot orthoses made primarily from carbon fibre composite. This will then be used to identify the potential sources of exposure of hazardous materials that can lead to health issues. To answer the problem statements theory about process mapping has been gathered and observations in the shape of video recordings have been done at Borås Orthotics to map out the current situation, in addition to interviews. The purpose of the process mapping was also to identify potential sources of emission where exposure to hazardous materials was evident. Theory and research about these materials has been gathered about the potential health issues. The exposure times from the sources of emissions has been compiled from the video recordings, where it was deemed to be four possible sources, in the form of dry carbon fibre bands, casting with poly methyl methacrylate, sanding and gluing. The exposure times and the sources of emission has been analyzed and compared with theory and research to investigate if there was any possible health hazards. The discussion has most importantly been about how the manufacturing of hazardous materials can affect the employees in terms of health and how the exposure times can be reduced. The conclusion is that certain sources of emissions run a greater risk to affect the employees negatively and certain measures might be in order to in terms of changing how the work is performed. It might be worth some reconstruction to make the work place safer in addition to reviewing certain methods. In general the regulations are a good idea to abide by since they are intended to prevent exposure for employees that work materials such as carbon fibers. Other practical suggestions of how to reduce the exposure to hazardous materials are included. An example of this could be to install a mirror solution in the fume cupboard at the casting process or to look at the routines and the work methods applied at the sanding process. The regulations should also be compared to how the work is currently performed and applied according to the work environment regulations.

    Campus Thailand – a new strategy to meet new demands2013Conference paper (Refereed)
    Abstract [en]

    Since the early part of the new millennium the student application rate has declined in the field of engineering. At the same time the demand from companies has changed to more general degrees that also include international experience. As the world becomes evermore internationalized, companies need employees who can operate in the international market with insights into business culture across the globe with knowledge of sustainable development. All this was an enabler to start to think “out of the box” in order to design a new program. The name ofthe program is ‘International Business Engineering’, a three-year bachelor’s program, 180 ECTS. It includes main subjects such as business, quality, logistics, operations research and management. A mix that provides overall knowledge, catering to the needs in international careers. The program embraces a multi-national and multi-cultural outlook and an education that enables work for a sustainable development, integrated in the global economy. It starts with three semesters in Sweden. The fourth semester is located to Campus Thailand and the last semester gives the students an opportunity to do their thesis work in a number of countries around the world. It commenced in 2009 with 40 students, only half of which were Swedish. All courses are given in English by teachers from Sweden, Thailand, Cuba, South Africa etc. This first year there were 5 000 applicants from 80 countries. The courses often include group work, which also gives the students insights into and knowledge of cultural differences.

    Campus Thailand is located at the Asian Institute of Technology (AIT). A semester there makes the students part of a multi-cultural student environment. AIT has become a leading regional institution and is working towards technological and sustainable development in Asia and the area around the Pacific. CSR Asia is involved at AIT, teaching the students and performing field trips for the students in the South Asian region, including Cambodia, Myanmar, Laos, Thailand and more. Around 70 percent of all students and staff are international withover 40 nationalities represented, giving important international contacts for the future. Cooperation with the Thai-Swedish Chamber of Commerce and its many member companies enables the students to carry out internships with global companies such as SAS, ABB, Volvo, Electrolux and Husqvarna.

    Lean implementation in geriatric care in a municipal: A case study from Sweden2014In: Proceedings of 2014 International Conference on Technology Innovation and Industrial Management, 28th-30th May 2014, Seoul, South Korea, 2014, S4-87-S4-99 p.Conference paper (Refereed)
    Abstract [en]

    Purpose: The aim of this research is to examine how lean has been implemented at geriatric care in a municipal department in Sweden, focusing on the experiences and challenges of the employees, together with the strengths and weaknesses of the lean philosophy.

    Design/methodology/approach: The primary method used was a case study with interviews and observations on spot, in combination with a literature study. All with the intention of defining and describing lean, its value, and how organizations generally apply lean.

    Findings: All sources of information have shown that there are many advantages with lean such as better communication and a better-organized workplace. In addition, lean tools help to eliminate non-value adding activities (waste). However, implementations also bring about issues and challenges such as the difficulty of creating a long lasting lean commitment. A lack of follow-ups and the decreasing demand for lean from the executives have been the main issues within the geriatric care. The next step might be to create a common organizational culture, which is permeated with continuous improvements, focusing on value-adding activities for the residents and others stakeholders.

    Originality/value: Very few studies have addressed lean implementation in geriatric care as well as in a municipal department.

    Lean implementation in the geriatric care sector in Sweden2015In: International Journal of Six Sigma and Competitive Advantage (IJSSCA), ISSN 1479-2494, E-ISSN 1479-2753, Vol. 9, no 1, 56-71 p.Article in journal (Refereed)
    Abstract [en]

    The aim of this research is to examine how lean has been implemented in the geriatric care sector in a municipality in Sweden. The research focuses on implementation experiences and challenges encountered. The research method used is a case study using interviews and observations for data collection. The findings indicate that there are many advantages of lean in the geriatric care sector, such as better communication, organisation and workflow. The lean implementation worked as an eye-opener and created a situation, where the employees realised a great deal of waste in the daily operations. In addition, lean tools helped to reduce the waste. The findings also indicate that there are some challenges of lean in the geriatric care sector, such as the difficulty to create long-lasting lean commitment. A lack of follow-ups, decreasing interest from senior management and lack of a holistic view were the main issues in the case organisation.

    Lean Six Sigma strategy in telecom manufacturing2014In: Industrial management + data systems, ISSN 0263-5577, E-ISSN 1758-5783, Vol. 114, no 6, 904-921 p.Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to elaborate, how the use of a joint-use strategy of Lean and Six Sigma can improve flexibility, robustness, and agility. Telecom manufacturing has been under tremendous change after dot.com bubble burst in the early 2000, and new competition has originated from Asia. Being successful requires now more than before, and joint-use of strategies is one option to survive.

    Design/methodology/approach – A single case study from a Swedish company operating in the telecom manufacturing was conducted. In particular, a Six Sigma project was followed and analyzed during 2002. However, the outcome of the Six Sigma project has been studied in longitudinal manner until 2014.

    Findings – The Lean Six Sigma strategy ensures flexible, robust, and efficient processes. However, to make them more agile in order to sustain in today's highly competitive environment, something more is required. This could include staff training, strengthening company culture and collaborating with key partners in the supply chain.

    Research limitations/implications – This study is limited to large company that usually has a lot of resources and choices where to put the strategic emphasis as well as has level of control of the supply chain operations. The situation could be very different in small and medium-sized companies and thus it may be more difficult to realize the Lean Six Sigma strategy in such environment. On the other hand, the processes in these companies are often less complex.

    Practical implications – This research provides guidance on how to manage the Lean Six Sigma strategy in order to ensure more flexible, robust, and efficient processes as well as how to perform a Six Sigma project in Lean environment, in a proper manner.

    Originality/value – This research provides guidance to companies regarding the applicability and properties of the Lean Six Sigma strategy. The paper will also serve as a basis for other companies and industries, on how to survive in difficult times.

    Total productive maintenance in support processes: an enabler for operation excellence2015In: Total quality management and business excellence (Online), ISSN 1478-3363, E-ISSN 1478-3371, Vol. 26, no 9-10, 1042-1055 p.Article in journal (Refereed)
    Abstract [en]

    In order to stay competitive in today's marketplace, it is vital to reduce activities that do not create value. Lean production has in the last decade been seen as a philosophy to reduce non-value time. The office environment often presents a major improvement opportunity to reduce non-value time. Lean contributes positively to business performance applied in a manufacturing context and is also suggested to do the same in a service context. The purpose of the paper is to analyse and determine how total productive maintenance (TPM) can be applied within the support process and to identify effects from an employee and business perspective. A case study has been performed and a qualitative research approach was selected. Empirical data were gathered by using semi-structured interviews at one case company, but from several teams that had applied TPM. The result was then used as an inductive approach to explore how TPM can be applied in a support process. To implement and apply TPM within an office context, it should be structured in three steps (i) define, (ii) implement and (iii) sustain. TPM should be conducted as a part of the ordinary day-to-day work. The planning and discussions connected to TPM can be included in regular daily departmental stand-up meetings' involving everybody. The work with 5S and maintenance should also be a part of the TPM structure, connecting it as a system and not as an isolated activity. TPM can create value from both a business and an employee perspective. In the employee perspective, TPM reduces the risk of missing/forgetting areas of responsibility and creates more involvement. In the business perspective, objectives such as cost and quality are improved, but TPM also enables the reduction of waste.

    Preventive maintenance is an enabler for operation excellence in support processes2014Conference paper (Refereed)
    Abstract [en]

    TPM in a Lean office environment can create values both in a business and an employee dimension. In the employee dimension TPM reduces the risk of missing/forgetting areas of responsibility and creates more involvement. In the business dimension objectives such as cost, quality and supporting the reduction of waste improved. Preventive maintenance meetings can be included and performed once a month in the ordinary departmental “stand-up meetings”. Methods like 5S, which need to be updated on a continuous basis, and standardized maintenance should also be connected to the TPM work. But first all employees should be trained in order to have the same direction/behavior.

    Kartläggning av sjukfrånvaro på en distributionscentral2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of this study is to identify patterns in the absence due to illness at a distribution center with higher absence due to illness compared to other companies in the same industry, and to investigate how managers work with routines for absence due to illness. To achieve the purpose, it has been divided into two research questions:

    1. Which patterns in absence due to illness can be found at a distribution center with higher sick leave compared to other companies in the same industry?

    2. How do managers work with routines regarding the absence due to illness at a distribution center with higher sick leave compared to other companies in the same industry?

    Method – Theories about sick leave, work environment, psychosocial health, motivation, organization and leadership were collected to fulfil the purpose of the study. A case study was carried out to collect empirical data on the basis of interviews and document studies which then were compared with the theory for further analysis.

    Findings – The study identifies patterns that were found after mapping the statistics of the absence due to illness on the case company. The result shows that women have higher absence due to illness than men, mostly younger women and older men. Permanent and temporary employees have more absence due to illness than workers on deputy posts and that employees who have worked one to three years have more absence due to illness than other groups. The mapping also shows that employees have the highest sick leave in the fall, on Mondays and only one day is most prevalent. There are clear routines regarding sick leave and rehabilitation at the case company. Improvements can be made with the documentation in the web-portal for sick leave, how the first day reporting sick should be done, and that a comprehensive action plan could be designed for managers to use. The study shows that the managers who are committed and have a higher focus on creating a good group dynamic through activities generally have lower absence due to illness. By creating a satisfying work environment where employees have the opportunity to participate, influence, take responsibility, develop and be seen and heard can therefore improve productivity, motivation and workplace health.

    Implications – A mapping of absence due to illness can improve the same work on other companies and create a greater understanding of why some groups have higher absence due to illness in the workplace than others. This case study also shows that the work environment, motivation and leadership are essential to encourage health in the workplace which can be applied on companies in several sectors.

    Limitations – Deviation may have occurred as a large amount of data during the study was processed. To do a mapping is considered generalizable but the result may differ between companies, therefore is the study not applicable in all contexts. The authors consider however that the study could be applied in general to other businesses as work environment and absence due to illness is an issue in all industries.

    Hissautomaters påverkan på lagerhantering2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: This study deals with warehouse management with an emphasis on vertical lift modules (VLM). The aim is to examine the effect of the implementation of VLM on a business's warehouse management. In order to obtain a result, the study has been based on the following questions:

     How was the warehouse management designed before the implementation of VLM?

     How is warehouse management designed after the implementation of VLM?

    Method: To be able to answer these questions, interviews with ten users of VLM performed. All users usually lift systems from the same manufacturer. Among the users who visited the interview sessions observations have been carried out to better understand how the stock handling of the user is configured. The results of the interviews and observations have since been compiled in the form of tables. This is to make it easier to compare and highlight the distinct differences of inventory management before and after implementation of the lifts. The study has only examined how the implementation of vertical lift module impacted inventory management, although another storage equipment acquired in connection with the implementation of VLM.

    Results:The majority of users have the same design at the warehouse as they were before the introduction of the VLM. Most have replaced shelf compartments storage and use the new storage equipment with the existing one. With the help of the lifts, users have also reduced transportation distances in the warehouse, which has resulted in faster retrieval times. Article Readers acquired in connection with the lifts have also affected the picking time for the better.

    Many of the users have chosen to implement a VLM due to lack of space in the warehouse. In cases where the user have not been able to expand its warehouse VLM have been deemed suitable alternatives. Users who have been interviewed agree that the lifts have been a positive investment, which in the end has also proven to be cost-effective. Users find that the lift saves time and, in some cases, reduces the required amount of workforce as a result of a significantly more streamlined warehouse management.

    Implications: Results from the study can be beneficial for companies that are looking to acquire VLM to its storage facility. The results can also help students gain a deeper understanding of how the change of storage equipment can affect a company's inventory.

    Decision making framework for managers: Profit by forecasting, costs and price management2009Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Forecasting, cost management and pricing policies are topics which have beenwidely investigated over time. Due to a lack of scientific research about therelationships between each of those subjects, these methods have beeninvestigated in combination with their outcomes. The purpose of this work was todevelop a framework which can be used by managers who want to make adecision in either of the subjects mentioned before. By the use of a qualitative, interpretive research design, a literature review was performed which led to some interesting findings. Generally, it can be said that the methods are not related directly, although the outcomes are linked and can often be used as a criterion for the decision making process for the other methods.

    Investigation of volume and product mix flexibility in batch production2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Today’s business environment involves a globalised market, greater than before competition and more challenging customers, all factors which contribute to higher uncertainty and variability. Manufacturing flexibility is becoming more important in order to cope with the complexity of products through frequency volume changes and evaluations of the technological requirements of products.

    The research for this thesis was performed within a subcontractor company, Laserkraft AB, who focus on laser cutting, turning and welding processes in their production. The company utilises a variety of volume and product mixes, which is in correlation with the objective of this study.

    The purpose of this research was to investigate the common source drivers in order to achieve volume and product mix flexibility on batch production systems. First, a literature review was conducted in order to build the framework of common source factors between volume and product mix flexibility. Then, a single case study was conducted to examine the outcomes of framework on batch production. In this case, qualitative techniques included interviews and an observation of the shop floor.

    The analysis of this study was conducted with empirical research on a case study and theoretical framework from literature. From the literature stand point; it was found that flexible manufacturing competencies (FMC) and strategic flexibility approaches are two main elements to determine internal source drivers between volume and product mix flexibility. The groups of common source factors were then analysed with respect to characteristics of batch production systems at the chosen company.

    A comparison between the framework and the empirical findings identified source drivers in order to achieve volume and product mix flexibility. Due to the limited nature of the study, all source factors that have an impact on achieving volume and product mix flexibility might not be presented in this thesis. Besides, it is difficult to generalise the result on a single case study.

    As a result, each organisation and industry refers to their product, process and type of layout, and requires a group of practices to achieve volume and product mix flexibility. This thesis concludes with the top three common source factors between volume and product mix flexibility such as: set-up time reduction, multi-trained employees and advanced manufacturing technology.

    Kartläggning och analysering av produktionsplanering av order med specialkvalitet hos Stora Enso Packaging AB2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    This investigation’s task was to map manufacturing of special qualities at Stora Enso Packaging under a certain period, analyze if rules concerning special qualities is followed, which consequences this results in concerning use of paper, waste and costs and to give suggestions on alternative solutions. The goal was to give sugges-tions that help the company to reach its business ratio that the production de-partment uses within use of paper and productivity in the corrugated cardboard machine.

    Stora Enso Packaging is a part of the forest group Stora Enso and is one of Swe-den’s leading producers of corrugated cardboard. Stora Enso Packaging acts pri-mary on the Swedish market, where they have a market share of 25 %.

    To be able to analyze orders with special qualities we did a data collection during two months, where we mapped incoming orders. The period for this mapping was set to 1 February – 31 March 2006. It was considered enough to see it as an aver-age for the whole year, as there were no mentionable season variations.

    There is given written rules for special qualities in Stora Enso Packaging’s manual for quality standard. The rules say that an order shall be at least 5000 m2. 177 of 270 orders in our investigation were less than 5000 m2, while 93 orders fulfilled the demands. The result clearly shows that most of the orders are not following the rules, which is quite remarkable considering the importance of effective plan-ning of the corrugated cardboard in the machine.

    One of Stora Enso Packaging’s four business ratio in the production department is the use of paper. Therefore we examined the use of paper for every single order dur-ing the data collection period and we show the result in three diagrams, partly for all orders and partly for orders over respectively under 5000 m2. The result shows that all orders that have a use of paper less than 50 % has also fewer than 5000 m2. It also shows that most of the orders have a use of paper between 91 100 %.

    The additional cost for the waste of corrugated cardboard was 83 % higher in SEK for orders over 5000 m2, compared with order under the same square meter limit. An important comparison is that orders over 5000 m2 are 7 times bigger in square meters than orders under 5000 m2. Of this comparison one can see that the addi-tional cost is bigger per ordered square meter for orders under 5000 m2. Further-more, the same indication shows when we compared the additional cost for waste with the revenue for every single order. Order under 5000 m2 shows a result of 12,5 %, while the same result for orders over 5000 m2 is 9,5 %. This shows an indi-cation of that orders under 5000 m2 increases the costs and decreases the productiv-ity in the plant.

    Produktutveckling i stadens tjänst: en explorativ studie om design av souvenirer2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    It is increasingly important for cities to attract visitors, potential new residents and businesses. Jönköping is one of the cities working with place marketing, a strategy that intends to mediate a positive image of the city, in order to accomplish just that.

    People often have a need to preserve the memory of a trip into something tangible. Anyone visiting Jönköping encounters a souvenir choice, much like the one in many other cities. Linked to the idea of positive place marketing, our work aims to investigate how we as product developers can create a product that en¬hances the image of Jönköping based on the thought that all residents are con¬sig¬nors. Accordingly, we develop three different products from the residents' own image of the city.

    Our research questions are:

    Based on the photographs, what image of Jönköping do the ambassadors mediate of their own city?

    As designers, what in Jönköping's history versus the image of Jönköping today, can we seize in order to give products for visitors a sense of authenticity?

    As designers, how can we use knowledge of place branding in the development of souvenirs?

    We performed interviews within three different aspects: history, souvenirs and place branding, all focused on the city of Jönköping. The interviews and a work-shop formed the basis for the further design process.

    This work has resulted in three products: the matchbox Det nya Jönköping i en historisk förpackning, highlights an important part in the city's history and becomes a conversation piece. Lek dig genom Jönköping want to show visitors what the city offers, and distinguish it from others, from the on-site. Detaljerna gör staden is an every¬day object and function can get residents to begin to discover the details of their own city.

    Through the use of knowledge and theories of place branding and souvenirs, we would argue that we have found a way to actually catch the residents' image of the city in a number of products. We also believe that it would be able to apply this type of project in other locations to create more authentic and at the same time innovative souvenirs.

    Förbättring av leveransservice inom ett produktionsflöde mellan en intern och en extern operationsenhet – från ett tillverkande företags perspektiv2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Purpose – The purpose of the study is to identify the challenges that arise in the production flow of a manufacturing company between an internal and external operating unit and how these challenges can be managed to achieve higher delivery performance in the production flow. The following two questions where formulated in order to fulfil the purpose of the study:

    1. 1.     What challenges arise in a manufacturing company in the production flow between an internal and an external operating unit.  

     

    1. 2.     How can the challenges in a manufacturing company be managed to improve delivery performance in the production flow between an internal and an external operating unit.

    Method – To answer the questions of the study and thus fulfil the purpose a case study was conducted at Bufab Lann AB in Värnamo. Observations, interviews and document studies were conducted to obtain empirical data. Empirical data was analysed against the theoretical framework of the study to answer the study questions. 

    Findings – Three challenges were identified in a production flow between an internal and external operating unit: Unlevelled internal production flow, lack of supplier collaboration and inadequate information and communication exchange. The challenges interact with each other, where internal problems are reflected and magnified when an external operating unit is included in the processing operation. To manage the identified challenges with regard to delivery performance must initially the internal production flow be levelled and thereafter establish closer relationships with suppliers and improve the exchange of information to suppliers.

    Implications – Synchronizing planned production to the end customer’s delivery date can level the internal production flow while also applying FIFO principles to overloaded stations. To establish good supplier collaboration the number of suppliers should be evaluated to simplify and maintain frequent and routinely information and communication exchange. 

    Limitations – During the study a single case study was conducted with one analysing unit, which is not optimal to obtain generalizable results. Conducting additional case studies in several manufacturing companies would have increased the study´s external validity and thus strengthened the generalizability. The study´s reliability is limited with regard to the views and opinions of the study´s external operating unit since only one interview was conducted with the external party.     

    Keywords – Production flow, delivery performance, supplier collaboration, information exchange.

    Leveransledtidsreduktionens påverkan på finansiell prestanda: - En studie i tidens tecken2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The study aimed to investigate how a delivery lead-time reduction impacts returnon-investment (ROI), and through the study create a decision support that quantitatively demonstrates the impact of the delivery lead-time reduction on manufacturing companies' ROI. To fulfill the purpose of the study two research questions were created:

    1. How is ROI affected by a delivery lead-time reduction?
    2. How can the impact of the delivery lead-time reduction on ROI be quantified?

    Method: A literature review was conducted to explain how a delivery lead-time reduction affects the ROI components. The literature review formed the theoretical framework, from which a proposition was created. With the proposition as a basis, a case study of one-case-design was carried out. The data for the first research question was collected through interviews with respondents from the focal company's market and production departments. The collected data was then pattern matched against the proposition, to develop the proposition. The answer from the first research question was then used as a basis for the quantification of the impact of the delivery lead-time reduction on ROI. During the empirical collection, there were limitations in data availability, therefore fictitious data was estimated to carry out the quantification and fulfill the second research question.

    Results: The study shows that there are many ways in which ROI can be affected by a delivery lead-time reduction, depending on the context, the starting point, and the approach in which the reduction is implemented. Therefore, an 8-scenario typology was created for how a delivery lead reduction can be implemented based on the six strategic lead times (SLT). Research question 1 shows, based on the data and the proposition, how delivery lead-time reduction impacts ROI in the typology’s scenario 7. Scenario 7 means a reduction in delivery lead-time, along with a reduction of the supply lead-time by reducing the external lead-time. The quantification of fictitious data, which answered the second research question, showed that it is possible to quantify the effect of the delivery lead-time reduction on ROI. Based on the approach of quantification, a decision support for investment in delivery lead-time reduction was created.

    Implications: The study contributes to the opportunity for practitioners to evaluate investment in delivery lead-time reduction, against other investment candidates, to strengthen the company's competitiveness. Theoretically, the study contributes with the typology for how a delivery lead-time reduction can be implemented. Also, a contribution through the proposition which shows how a delivery lead-time reduction generally affects ROI, versus the developed proposition that shows the influence based on scenario 7.

    Limitations: The quantification was based on fictitious data, which gave a limited result. Although it’s not the result of itself that is of interest, it is the logic of quantification, since the purpose is to develop a decision support. Also, the study is of one-case-design, whereupon the developed proposition cannot be applied on other companies without scrutiny and compared with their specific contexts.

    Ledtidsreducering vid Saab Training Systems Ab: Lead time reduction at Saab Training Systems AB2007Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Detta examensarbete är utfört på Saab Training Systems AB i Huskvarna. Saab Training Systems utvecklar, tillverkar och säljer kompletta militära träningssystem.

    Syftet med arbetet var att minska ledtiderna, då korta leveranstider blir ett allt viktigare konkurrensmedel. Arbetet innebar en kartläggning av nuvarande reserv- och reparationsflöde samt att identifiera problem och komma fram till förbättringsförslag.

    Vidare har vi studerat reservdelslagrets lagernivå och dess kapitalbindning.

    Arbetet genomfördes med hjälp av intervjuer med berörd personal, observationer, enkätundersökning samt statistiska studier. Vi har även arbetat med Supply Chain Operations Reference Model som är en öppen referensmodell med vars hjälp man kan kartlägga, förändra och optimera sin verksamhet.

    Saab Training Systems har som mål att ledtiderna för reservdelsflödet och reparationsflödet skall vara 14 dagar, men i själva verket är det inte så. Dessa ledtider är idag längre, hur långa är dock oklart.

    De långa ledtiderna beror främst på att i flödena förekommer det mycket passiv tid. Tiden uppstår bland annat i väntan på transport men även som en konsekvens av att företaget för tillfället har mycket att göra.

    För att reducera ledtiderna bör Saab Training Systems i första hand reducera den passiva tiden.

    Saab Training Systems bör sänka sina lagernivåer för att frigöra bundet kapital vilket leder till att de minskar risken att produkterna minskar i värde eller blir inkuranta.
