    Analysis of the congruence between manufacturing strategy and production system in SMME2001In: MANUFACTURING INFORMATION SYSTEMS: Proceedings of The Fourth SMESME International Conference Stimulating Manufacturing Excellence in Small & Medium Enterprises / [ed] Hans-Henrik Hvolby, 2001, p. 95-102Conference paper (Refereed)
    Abstract [en]

    A production system must reflect a company’s manufacturing strategy and the chosen competitive priorities. Tools to assess the congruence between the manufacturing strategy and the production system can hence support the companies’ competitive position. In this paper, the usability of an analysis model suggested by Miltenburg (1995), aiming at mapping manufacturing strategy and production system is investigated. The usability of the analysis model is investigated in terms of the ease to use it and in terms of the obtained results. The investigation is performed by means of empirical studies in two medium sized manufacturing companies. The result is that the model seems to be useable in the senses that, if knowledge about the underlying principles in the analysis model is at hand, it is possible to investigate the congruence between manufacturing strategy and production system. It is, however, believed that the analysis model needs some further development to be considered an easy to use tool for e.g. the SMME production manager.

    Manufacturing strategies supporting competiveness in SMME2011Conference paper (Other academic)
    Abstract [en]

    Research on manufacturing strategies has been quite extensive during the past 40 years. The work has however been mostly focused on large companies. It has also mostly had a top-down approach, emerging from the view of top management based on market requirements, not taking production capabilities into consideration. It is however necessary to make a reconciliation of capabilities and competitive factors. In this paper we present the first results from a project on manufacturing strategies in small and medium sized manufacturing enterprises, SMMEs, in Jönköping region Sweden. This first step of the three year project is a survey and diagnosis of the present situation in the participating companies. We can see that the companies show different degrees of strategic maturity, which to some extent could be the consequence of them acting in different industrial areas with varying requirements, traditions and values. A common learning is that, even if the company does have a well-developed manufacturing strategy and ideas about future development, the communication out in the organization to employees is lacking. This leads to reduced sense of responsibility and commitment among the personnel.

    Development of a manufacturing strategy framework for SMEs2014In: Proceedings of the 21st EurOMA Conference, June 20-25, Palermo, Italy, International Annual EurOMA Conference, 2014Conference paper (Refereed)
    Abstract [en]

    Small and medium-sized enterprises (SMEs) are very important to European industry, acting as suppliers to global companies, but also as OEMs. To keep up with competition from global sourcing, they however need to be pro-active and have clear ideas on how to compete. In this work, manufacturing strategies may constitute the necessary guidance. In this paper we present the development of an analytical tool for manufacturing strategy formulation, easy to use and thus suitable to SMEs, who often lack resources in terms of competence or money.

    Requirements on manufacturing strategy frameworks for SMME2012In: Proceedings of Swedish Production Symposium, 2012Conference paper (Refereed)
    Abstract [en]

    Small and medium-sized enterprises are crucial for national finances and economic growth. For small and medium-sized manufacturing enterprises (SMME) it is essential for competiveness that manufacturing supports the overall company goals. Despite this, previous investigations show that it is mainly larger companies that are aware of the role of manufacturing for competitiveness and therefore formulates manufacturing strategies. The purpose of this paper is to increase the understanding about how manufacturing strategy formulation can be facilitated within SMME, and specifically on requirements that are raised on frameworks to support the work with manufacturing strategy processes. The presented results are based on five case studies, carried out in five different small and medium-sized units/companies. The result indicate that they on the one hand want the framework to be easy to understand and to use, but on the other hand it should be comprehensive, and it should provide recommendations for actions. Furthermore, a framework has to consider aspects related to the actual work procedure, the use of the framework, and with the outcome of the work. This analysis provides a valuable foundation for the on-going work of developing a framework for manufacturing strategy formulation adapted to the characteristics among SMME.

    Usability of a manufacturing strategy framework developed for SMEs2014Conference paper (Refereed)
    Abstract [en]

    Still, 45 years after Skinner’s (1969) call for manufacturing strategies, explicit manufacturing strategies are scarse in manufacturing industry, especially in SMEs. Together with a number of SMEs, we have developed a manufacturing strategy tool, aimed at supporting manufacturing strategy formulation. In this paper, the focus is on requirements on a manufacturing strategy tool related to the usability in SMEs. Results from evaluation of the tool during development is presented. The resulting tool was considered to be useful to the participating companies, helping them to get over the initial treshold of working with manufacturing strategies.

    The content and process of automation strategies2005Conference paper (Other academic)
    Abstract [en]

    Modern manufacturing systems are often semi-automated, i.e. integrating both manual and automated op-erations. Our studies show that decisions on how, and even if, automation should be realized often are taken in an ad hoc manner. Improved efficiency in production through automation could be achieved with better precision if a more conscious approach towards automation was used. We argue that it is essential to formulate explicit automation strategies, which will provide guidance to the appropriateness of automa-tion in different situations. Further, it should give advice as to the most suitable degree of automation needed. Two different perspectives on automation strategies have been identified through a literature re-view and empirical studies. The first perspective is when decisions concerning automation are treated as one of several decisions in a manufacturing strategy. The second perspective is when the overall manufac-turing strategy is equal to an automation strategy, i.e. the strategy is automation. The paper elaborates on the content and process of automation strategies, i.e. what must be included in a strategy and how is it formulated.

    Abstract [en]

    If automation is to support the competitiveness for a manufacturing company, strategic as well as operational issues need consideration. To best support competitiveness, decisions concerning automation should be treated as one of several decisions in a manufacturing strategy. Furthermore, to fully utilise the advantages from automation, the manufacturing strategy content and process needs refinement. In this paper improvement of the manufacturing strategy theory is suggested, mainly based on employment of human factors engineering.

    Frigöring av kapacitet i ett kundorderstyrt företag2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Rapporten syftar till att belysa de olika metoder som finns för att frigöra men också synliggöra tillgänglig kapacitet. Det efterfrågades av fallföretaget, då de efter att ha börjat tillverka ytterligare en variant i fabriken i Jönköping fick problem att göra klart alla ordrar i tid. Fallföretaget monterar elmotorer i sin fabrik.

     

    För att lösa problemet har studenterna valt att använda sig av en kvalitativ metod. En fallstudie på fallföretaget, SEW Eurodrive, har genomförts. Under arbetets gång har studenterna använt sig av intervjuer och observationer för att finna nödvändig information för att föra arbetet framåt.

     

    För att kunna visa företaget hur stationen kan balanseras på ett bättre sätt gjordes observationer. Utifrån de observationer och mätningar som gjorts insåg studenterna att monteringen är uppdelad i tre moment och att det är moment två som tar längst tid. Layoutförslagen som bifogas till rapporten utgår från att det är moment två som är problemet. De bygger till stor del på hur fallföretaget skulle kunna bygga om stationen för att på så sätt frigöra mer kapacitet och förbättra arbetssättet.

     

    Eftersom arbetet är av mer teoretiskt karaktär är det svårt att peka på ett tydligt resultat av den uppställda empirin. Genom att göra en liten ändring i stationens uppbyggnad skulle arbetet kunna flyta på bättre och möjliggöra att flera personer kan arbeta på stationen samtidigt.

     

    Det generella syftet med rapporten begränsas av att en fallstudie har gjorts på ett kundorderstyrt företag. De företag som tillverkar mot lager kan använda sig av dessa metoder, men måste då vara medvetna om skillnaderna mellan ett kundorderstyrt företag och ett företag som tillverkar mot lager.

    Abstract [en]

    This examination thesis includes a master thesis written by two graduate students studying product development and design at the school of engineering at Jönköping University. The assignment consisted of producing a product suggestion that facilitates handling of a shopping list at a grocery store.The thesis resulted in a final concept that were apprehended by creating a functioning prototype. The product consists of a plate, an attachment for a shopping cart, two snap-in strips, a lid and a penholder. The product has a smooth attachment that facilitates assemblage of the product and makes it suitable for the customers’ demands.The assignment originates from the one-man enterprise Sirge AB that in its turn took contact with the consulting firm Sigma Industry. The company weren’t established within the product development sphere and therefore didn’t possess the right expertise that were needed to get the job done. The contact person at Sigma Industry considered the assignment suitable to be done as a thesis.Sirge AB had found a gap in the market for products that simplifies the problem for customers at the grocery store. The request from the client were to develop a product that easily could be attached to a shopping cart and facilitate the handling of a shopping list. The reason for this were to avoid keeping multiple things in the hand at the same time and instead free the hands for grocery shopping. To achieve the objective, three questions of formulation were formed that were summed up with a main question of formulation:“How will a helping device be design to facilitate the handling of a shopping list at a grocery store, and also be flexible enough to handle both analogue and digital lists, be customer owned and with right material choose?”To answer the main question the project group applied the method of Bootcamp Bootleg. The work commenced with a pre study with the purpose to examine the interest amongst the future customers and create a focus group. A market research were also made to see which competitors that were already on the market and to see how well the new product would fit into the market. Several concepts were developed through the method brainstorming and were then evaluated through a SWOT analysis and an elimination matrices. The concepts that were chosen were then developed in the CAD program SolidWorks.The final concept consisted of a plate with the primary function that makes it possible to attach a shopping list. The product also offer secondary functions like a holder for a pen, a phone, and extra space for storage of other objects. The main part of the product were produced in 3D printing. The snap-in strips and parts of the attachment is standard components. The penholder were made out of leather and the lid in Plexiglas to give it a nice look.

    The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.

    The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit. To reduce cost depends to what extend the program is helping the user to achieve goals during the design execution. The thesis also includes an investigation of the factors that affect the design of such a program. To explore appropriate strategies was a theoretical design process implemented in the study. From the perspective of technology has the author utilized knowledge in engineering design and programming. The program approach utilized was Visual Basic languish in Visual Studio enviroment for the user-interface and a Catia V5 CAD-platform for the chainsaw design.

    The result is a program which could use reconfigured parameters as needed to create customized designs correctly and effectively. This thesis has also resulted in appropriate principles for the design of a user-friendly interface that were up for the task to be a supporting tool through the execution. It has also been established appropriate tools and methods for analysis and optimization of the program. The author feels that the results of methods and principles in this study were of high reliability and can therefore be applied to other projects, even if the results only are valid for this specific case.

    Analys av provkörningsprocessen på Wexiödisk AB2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study has been conducted in cooperation with Wexiödisk AB. The study has taken off in the Wexiödisk’s testing process, where all dishwashers are tested for function and safety before they are delivered to the customer. The test process is complex where several sub processes are included, including high voltage testing and insulation measurement.

    The study's questions are based on the problems that Wexiödisk experiences with the current test procedure. The authors have chosen to focus on three problem areas: Deviation management, Traceability and Usability. These are included in the overall area of ​​the study, which is referred to as quality assurance.

    To achieve the purpose of the study, a current position description was made to describe the current situation at the test station. Through examination of internal documents as well as observations and interviews, the test process has been described.

    The study's analysis has shown that the large variant management of Wexiödisk leads to ambiguity of the current test procedure and the fact that the test protocols are largely unused. In addition to this, it was found that traceability on component components is lacking, and that there is no control that all test components have been performed in the final test.

    To address these issues, the authors suggests that individualized test run protocols for all hardware variants should be developed. Furthermore, it is suggested that the test run procedure should be digitized. The digitized test run procedure is proposed to contain a standardized sequence order to reduce the variation in the test run process. In order to be able to identify shortcomings in the production process in the long run, it is also suggested that the test run report contains a deviation report.

    Abstract [en]

    The concept of sustainable development has emerged into manufacturing since late 1990s and has focused on increasing competitiveness by improving environmental and social performance. Considering the global competitive environment, legislations, and customers’ awareness of sustainability issues, companies are expected to be aware of their impact on the triple bottom line i.e. people, planet, and profit. The purpose of this paper is to explore how companies go from vision of sustainability to accomplish sustainable operations management. Multiple case studies are conducted to provide findings on how sustainable operations management can be expressed in terms of the principles, practices, and tools.

    Simulation of thermal stresses in a disc brake2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The heat flux produced from the friction between a disc and pad system leads to a high temperature which causes thermal stresses in the disc and after a number of repeated braking cycles, cracks might be initiated. The finite element analysis (FEA) is performed to determine the temperatures profile in the disc and to analyze the stresses for the repeated braking, which could be used to calculate the fatigue life of a disc.Sequentially coupled approach is used for thermo-mechanical problem and the problem is divided into two parts, heat analysis and thermal stress analysis. The heat analysis is obtained by including frictional heat and adopting an Eulerian approach. The heat analysis is conducted by using Abaqus and the toolbox developed by Niclas Strömberg. The thermal stress analysis, which is the main focus of this thesis, is followed using Abaqus. The plasticity theory as background for stress analysis is discussed in detail. The rate independent elasto-plastic plasticity is used in the stress analysis. Temperature independent material properties are considered throughout the thesis work.Isotropic, kinematic and combined hardening models are analyzed for simple 2D academic models for different types of cyclic loads. A benchmark disc and pad model, which is less complicated than the real disc-pad model, is also studied. The linear kinematic hardening model with rate independent elastic-plastic plasticity is used for benchmark and real disc-pad model. The results of the benchmark model and the real model are observed to be similar in terms of plasticity theory.

    Reliability Design in Structural Optimization - Literature Survey2013Report (Other academic)
    Abstract [en]

    This survey focuses primarily on the historical development of RBDO and the various classes of methods which emerged through the years. While reviews on contemporary RBDO methods have been done previously, they haven’t incorporated the basis on which such developments were possible in the first place — risk-based design and limit-state design. This study attempts to link the RBDO field with these methodologies for a more complete picture of the field of reliability and safety.

    Evaluating the applicability of sea basing to support the preparation for, and response to, rapid onset disasters2016In: IEEE transactions on engineering management, ISSN 0018-9391, E-ISSN 1558-0040, Vol. 63, no 1, p. 67-77Article in journal (Refereed)
    Abstract [en]

    Using four case studies of the response of the international community to major rapid onset natural disasters, this paper analyzes the advantages and challenges inherent in the provision of logistics support through the use of a floating warehouse; otherwise known as “sea basing.” Through a comparison of the costs and benefits of the use of alternative sea-basing models with the actual cost of air transport incurred, this paper demonstrates that the use of sea basing would offer responding agencies significant cost and flexibility benefits, and that the concept has the potential to be extended significantly through the use of a bespoke vessel rather than a standard commercial container ship.

    Marknadsundersökning kring additiv tillverkning i Sverige2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Within the industrial sector, an increased interest and usage of Additive Manufacturing (AM) throughout the decade has been formed. The layer-upon-layer building technology has been seen and recognized as one of the next industrial revolutionizing methods of production. As the technology is still in the trending and uprising phase it should be considered that its full potential has not yet been achieved, as large opportunities for implementation of AM exist and that new companies and markets have a growing interest in this technology.

    Through this study a market research was conducted to identify and present what opportunities and obstacles there are for an increased usage of AM in Sweden. A literature study on the Swedish market has been made to present the market as of today. Eight qualitative interviews have also been conducted with companies within the industrial sector to identify the areas of use within AM for production. The concepts and models used to analyze these questions was PEST, Marketing Mix and SWOT.

    The concluded results for advantages in using AM are shortened lead times, reduced costs of production of components and tools, reduced material waste and optimization of design processes with increased creativity. The concluded challenges are expensive materials and machine, the quality of finished components, limited printing volume due to the 3D-printers and reliability of printing processes. The finalized opportunities that are presented in this work are that AM is dependent on how much research on the subject and factors around it is done. How AM will be applied in the coming future revolves around the advancement in the technology. The obstacles that are found in this study are lack of competence and lack of standard for materials and processes within AM.

    Bottleneck Improvement using Simulation based Optimization2016Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Manufacturing companies are constantly looking for new, innovative technologies and tools to find out the real constraints and Bottlenecks That impede the performance of Their Production Systems. There are Several approaches and methods thathave been Developing for decades to Overcome These constraints of production processes but They Are Not Sufficient to pinpoint the exact location and its severity. They overpriced Generally cases, short to suggest the way to Implement the right actions in the right order, to avoid sub-optimizations and wastes in Time and Expenses. So of of according to Recent Research In using simulation based optimization, it is believed That some more accurate and efficient methodology for Supporting Decision Making in Production Systems Development and improvement is badly needed. SCORE (Simulation-based Constraint Removal) is a promising methodology for Identifying and ranking the Bottlenecks of production systems That utilizes simulation-based Multi-Objective Optimization (SMO), Which was developed by Pehrsson (2013) as a part of his Ph.D. . . work. The main principle of this new methodology is The Application of SMO With The Objectives to maximize the throughput and minimize the number of required improvement actions Simultaneously. Additionally, by using post-optimality analysis to process the generated dataset optimization, the precise improvement actions needed to attain A Certain Level of performance of the production line are Automatically put into a rank order. The main aim of this project is, there fore, to apply this new technique in a real-world context, in order to understand how far this technique will support for decision making, village Conducting a simulation-based bottleneck analysis in one of the major Volvo Group Trucks facilities. This is to find out the Bottlenecks and optimize it in order to Increase the overall productivity. Three research questions related to the effectiveness and accuracy of the methodology will be answered through this real-world application study.

    Impact on the Design Phase of Industrial Housing When Applying a Product Platform Approach2018In: Proceedings of 26th Annual Conference of the International Group for Lean Construction / [ed] Vicente A. González, Chennai, India, 2018, p. 527-537Conference paper (Refereed)
    Abstract [en]

    With a glulam-based post-beam building system, a variety of building solutions is offered on the market for multi-story buildings. The building system must be adaptable to the demands of each project. However, short lead-time, efficient manufacturing and assembly must be ensured. The use of product platforms has been acknowledged as an enabler to manage external (customer) and internal (production) efficiency. The building system cannot be locked to a set of standard components as a high level of customisation is required. A set of methods and tools is needed to support the design work and to ensure that solutions stay inside the boundaries of the platform definition. The aim of this work is to map the state-of-practice in the design phase for a glulam building system from a platform theory perspective and outline a path forward for applying a sustainable platform development in companies where a component-based product platform does not suffice. Empirical data were gathered from an on-going product platform development including interviews and document analysis. The results show the lack of definition in platform-based product development from a theoretical perspective and need for development of support methods for design that align with different production strategies

    HPDC Die design for Additive Manufacturing: Simulation and Comparison of Thermal Stresses in HPDC die designed for Additive Manufacture2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Additive manufacturing has a great potential to benefit die manufacture by shortening the lead time considerably and lifting the limitations on design complexity imposed by conventional manufacturing techniques. However, AM has its own requirements that together are known as Design for Additive Manufacturing and account for the process limitations. One of the significant requirements is mass efficiency of the design (it should be as light as possible). If it’s not fulfilled, AM won’t be able to make an economical solution or substitution despite having outstanding benefits. The present investigation has been framed with respect to such concern.

    This investigation attempts to draw a comparison between the performance of two design variants. Additionally, it has been tried to study the employed method, document implementation of the approach, and identify the challenges in accordance with design for additive manufacturing.

    Simulation of thermal stresses generated in die inserts for a given component during one cycle of high pressure die casting is presented. Initial design of the die inserts is subjected to redesign with the intention of mass reduction by incorporating honeycomb structure. Temperature evolution and resultant thermal stresses are analyzed for redesign and compared to those of original design.

    Simulation of high pressure die casting was carried out in MagmaSoft to obtain temperature history of die inserts and cast. Implicit nonlinear elastic fully coupled thermal displacement model was setup in Abaqus in which Magma results were used as input for stress calculation.

    Results show that according to our specific design, HPDC die with thin walled feature cannot withstand the thermal and mechanical load. However, with iterative analysis and proper topology optimization, a lightweight complex geometry die can be successfully made.

    Övergångsprocessen till ISO 9001:2015: Metoder och hjälpverktyg inför skiftet till ISO 9001:20152017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The key point in this thesis has been to illustrate the overall picture of a transitions process where the tools and methods are applicable on all companies that will make the transition to ISO9001:2015. Furthermore has the case company’s current situation been thoroughly studied with suitable methods to prove how this can be done and the importance it has to easen the transition to a new standard. The key is to ease the transition process to ISO9001:2015 (figure 1).

    1. Which methods are suited to determine the current situation regarding ISO9001?

    This has been answered by collecting data by using many different methods. The methods were then compared to each other to figure out which differences and similarities there was. The used methods are: serveys, dialogues and a self-developed method ”metod för egen bedömning” (method of self-assessment). The analysis was conducted and the results show that the different methods came to partially different results. Furthermore, it’s important to analyze a subject from more than one perspective and by using different methods.

     2. What are the differences between ISO9001:2008 and ISO9001:2015?

     

    The method that were being used to determine the differences that existed between the standard systems consisted of a gap-analysis. The analysis was carried out by comparing the following demands in ISO9001:2015 and its correlation in ISO9001:2008 and the difference (the gaps) could be identified (Figure 11).

     3. Which auxiliary tools are suited for companies facing a simple and effective transition to ISO9001:2015?

    The current situation has been put in relation to three important and critical factors which, according to Poksinska[8], are crucial when implementing a new standard. Relevant tools have been designed based on these factors to allow companies to ascend to the new standard in the best possible fashion. Companies must fulfill the new standards, determined by the gap-analysis, to be certified by ISO9001:2015. Relevant methods have been constructed from the difficulties and needs the companies experienced during the transition process as determined by O. Makie, B. Haxha thesis 2016 [2]. These methods can be directly applied to all Swedish companies, no matter what kind of business the company is conducting, to make the transition to ISO9001:2015 as simple as possible.

    The results from this thesis are the tools and methods that was produced and these have got their origin from the company’s current situation or from the gap-analysis. It has also been important to relate these tools and methods to the theory that has been processed to show their purpose and that they are supported by a scientific basis. The auxiliary tools can be directly applied and could come to be a part of the everyday quality management.

    Orsaksanalys och lösningsförslag vid fel vid kommunikation av växelläge2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This bachelor thesis has been executed in cooperation with Kongsberg Auto-motive AB, Mullsjö, who develop and produce parts to the automotive industry.The company has received complaints on a gear lever unit which they produce and which sits in the customers’ trucks and buses. The failures have occurred relatively infrequently, but with enough margins to classify them as serious failures. These failures are connected to that magnet arm in the product which communicates with the transmission of the vehicle and leads to the consequence of an unusable truck that is in need of towing.The intent with this thesis is that the author should tackle the problems with the magnet arm on an engineering basis so that the root causes to the problems can be ascertained. The goal is to find these root causes to why the magnet arm breaks, or dislocates, and generate a design that prevents the problems from reappearing.To structure the work the author has used a method for problem solving called Six Sigma DMAIC which is the base for the whole project and therefore the thesis.Through extensive analyzes the author ascertained that the root causes for the problems with the magnet arm came from the design of parts, relating to the knob of the product, that enables two buttons to simultaneously be activated.The thesis resulted in a concept which together with the company´s solution removes the underlying root causes and prevents the problem from reappearing.

    Knowledge Management in the Cross-cultural Organisation; Imposed Cultural and Language Barriers vs. Risk of Sub-optimising and Distanced Organisational Identity2012In: Proceedings of the 5th International Swedish Production Symposium, SPS 12, 6 - 8 November 2012, Linköping, Sweden / [ed] Mats Björkman, Svenska Produktionsakademien , 2012, p. 567-574Conference paper (Refereed)
    Abstract [en]

    For the establishing cross-cultural organisations one central question has been how to balance the desired need for standardisation and still maintain consideration for the specific norms of the cultural context. While focus commonly been on customs, protocols of communication and interaction, less attention has been given to the creative environment and knowledge management over the cultural and language barriers. In this paper it is indicated that the move to a foreign domain can potentially reduce the platform for a creative exchange between agents of same culture and language constitution, and that the learning organisation should review the lateral move of the workspace from the individuals own language and culture specific context to the standardised organisational context. Moreover, the culture and language context is argued able to channel creativity when promoting sub-groups priorities, languages and characteristic thought worlds. The implications from an inherent risk of sub-optimising and a distanced organisational identity are also discussed.

    Strategic lead-times and their implications on financial performance2017Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The overall goal for manufacturing companies is to earn profit and increase shareholders’ value. To ensure that companies in fact are profitable, managers usually evaluate the company’s resources based on both financial and operational performance, to analyse if the resources are contributing with a financial return. One of the most critical resources and competitive advantages that manufacturing companies have is time. Time, however, is an intangible resource and challenging to measure financially. There are, therefore, few practical instruments available to support managers’ decisions when it comes to linking lead-time with financial performance, assisting managers to prioritize the lead-times that are of strategic value (i.e. strategic lead-times). The purpose of this research was, therefore, to analyse strategic lead-times within new product development, purchasing, and production, as well as the implications that strategic lead-times have on manufacturing companies’ financial performance. To fulfil this purpose, the following two research objectives were formulated: (1) to analyse strategic lead-times within new product development, purchasing, and production, and (2) to analyse the implications of strategic lead-times on manufacturing companies’ financial performance.

    The research presented in this thesis has been conducted within a research project (KOPtimera). To fulfil the research objectives and the research purpose, a combination of conceptual analytical research and case study research was used, utilizing a number of data collection techniques: literature reviews, interviews, focus groups, workshops, document studies, and observations.

    In general, it is concluded that strategic lead-times, as defined in the research, have high implications for manufacturing companies’ financial performance and that the length of the strategic lead-times will impact who owns the risk in the manufacturing system, who controls the system and where variants are possible to create. The research further presents the implications that strategic lead-times have on financial performance, as well as indicates that it is possible to evaluate lead-time performance through financial performance, using readily available and accepted financial performance measures. Based on the implications identified, also a framework (the FinaSt framework) was developed. This FinaSt framework takes into consideration that not only the extension, but also the existence of strategic lead-times has implications for manufacturing companies’ financial performance, and that these implications can be either direct or indirect.

    The results contribute to the literature focused on valuing lead-times and provide useful knowledge for managers, allowing them to gain a better understanding for strategic lead-times’ implications on manufacturing companies’ financial performance, thus allowing for better decision support when evaluating supply chain designs and prioritizing alternatives based on profitability (i.e. return on investment).

    Structuring a new product development process portfolio using decoupling thinking2020In: Production planning & control (Print), ISSN 0953-7287, E-ISSN 1366-5871, Vol. 31, no 1, p. 38-59Article in journal (Refereed)
    Abstract [en]

    The purpose is to develop a structured new product development (NPD) process portfolio for manufacturing companies that facilitates the organization of NPD processes for both standardized products, focusing on time-to-market, and customized products, focusing on time-to-customer. The research combines different literature streams, enriching and advancing the understanding of decoupling thinking in NPD processes of manufacturing companies. It includes extensive empirical data from six manufacturing companies and presents testable propositions for further research. The resulting NPD process portfolio separates technology development from product development, acknowledges the different drivers and outcomes of processes and addresses the lead-time trade-offs. It provides an overview of potential options for NPD processes and shows different pathways through the processes. Companies can use the portfolio to support decisions related to the overall configuration of their NPD portfolios, the role and the range of different NPD processes, as well as to determine when and how to engage customers.

    Strategiska ledtiders inverkan på räntabilitet2016Conference paper (Refereed)
    Abstract [sv]

    Tid och ledtid betraktas ofta som en konkurrensfördel samt påverkar ett företags ekonomiska situation. Sambandet mellan ledtid och finansiella nyckeltal är dock inte alltid självklart. I denna studie undersöktes därför empiriskt relationen mellan strategiska ledtider och det finansiella nyckeltalet ROA. Resultaten från denna studie bidrar till att öka förståelsen för ledtid som en kritisk egenskap samt minska det teoretiska gapet gällande sambandet mellan ledtid och finansiella nyckeltal. Resultaten kan vidare användas av företag vid utvärdering och prioritering av olika alternativ i försörjningskedjan.

    Some Common and Fundamental Characteristics of Four Supply Chain Strategies – Customization, Leagility, Postponement and Segmentation2018Conference paper (Other academic)
    Abstract [en]

    Balancing efficiency and responsiveness has been identified as an overall challenge for decision makers in supply chain management. The literature offers several strategies for managing this balance challenge. From a decision-making perspective this is a significant contribution but in combination the strategies also result in complexity related to the different alternatives offered. This study does, however, show that the strategies share a common foundation in terms of content related to decoupling thinking, which is based on flow discontinuities. Using the strategies’ individual strengths, a process is outlined that takes advantage of these strengths through a four-phase ongoing process.

    Leadership at different levels: A case study at PaperPak Sweden AB2007Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    The business climate of today demands high flexibility and quick responsiveness from suppliers.

    It has become essential for organizations to have effective leaders in all hierarchal

    levels, which understand and are able to work under these conditions. As the market requirements

    have changed, a new paradigm of leadership has evolved (Bryman, 1992). This

    paradigm puts more focus on charisma and how to motivate followers, which is the essential

    part of transformational leadership. According to Burns (1978), transformational leadership

    is a process between leader and follower rather than exchanges. This leads to the

    question of what effective leadership is and if it can be measured in some way. One

    method is the use of the Multifactor leadership questionnaire, the MLQ-test, developed by

    Bass 1985 from the full range model.

    The conducted research for this thesis is done at PaperPak Sweden AB, a manufacturer of

    disposable incontinence products located in Aneby, Småland.

    The purpose of this thesis is to evaluate if any differences and/or similarities in leadership

    can be found between or within the hierarchical levels. The intent with the report is also to

    investigate those variances and if they are positive or negative for an organization.

    A theoretical framework focusing on leadership has been collected, to enable the fulfillment

    of the thesis purpose. This framework will act as support for the analysis of the quantitative

    investigation, based on the MLQ-test. From this analysis, the authors have made

    conclusions and recommendations. The degree of transformational, transactional and laissez-

    faire leadership has been measured for the three leadership levels top, middle and low

    management. It could be argued that the top management should show the highest degree

    of transformational leadership, and low management the least, due to their positions and

    work tasks. The result of the analysis supported that theory to a large extent. However,

    lower management showed a significantly higher degree of transformational leadership

    than middle management. One explanation could be that middle management lives in a

    more stressful situation, working between top and low management, compared to the other

    two, which is supported by Grout (1994).

    Since the theoretical findings mean that leadership can be learnt and developed, the authors

    suggest that organizations always have to follow up and try to develop their leaders and

    managers towards higher degrees of transformational leadership. Finally the authors suggest

    that further studies of the MLQ-test should investigate the possibilities to include measurements

    of the technical side of leadership, since the test currently does not take those

    factors into consideration.

    Kalkylering av bearbetningskostnader2008Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    At a manufacturing company, due to the competition the price is reducedtowards the manufacturing cost. Therefore it is important to maintain control ofones costs and keep calculations up-to-date.

    This thesis deals with cost accounting at a aluminium-processing company. The report focuses on calculating machine cost per hour since the manufacturing costs are the major part of the total product cost.

    Managers on the company believe that the costs they use in calculations todayneither is up-to-date nor advantageous in a market aspect and due to that their calculations need to be revised. The machines cost per hour is a major part in the manufacturing calculation. The company wants to provide a competitive price that also covers their costs. Therefore the company needs to control and specify their costs.

    The costs for the CNC-machines calculated in this thesis was considerablyhigher than the costs previously calculated for the company. It surprised thecompany managers that since the last calculation the used hours had increased by 15%. Comparisions between the calculations showed that there was differences in how costs and incomes were allocated and which divisions that carried their own costs.

    To be able to compete about major orders the company needs to be able toprovide CNC-manufacturing at a price of 400 SEK for machines feeded byoperators and 200 SEK for the machine feeded by a robot. A target costcalculation was made to determine what changes is required to reach thosemanufacturing costs.

    The conclusion of this thesis is that it is possible for the company to offer aCNC-manufacturing-price below 400 SEK/hour and a Robot-cellmanufacturing-price below 200 SEK/hour. However it requires more control over the company’s costs and over how big part of the order that has the lower machine cost per hour.

    Konceptutveckling av interiörbelysning Thule Sweden2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis has been conducted at the School of Engineering at Jönköping University in cooperation with the outdoor company Thule Sweden AB with focus at an active lifestyle. The company wants to lift the lightning to the next level by integrating it with the roof box. Today’s lightning comes as an option and is attached to the rear hinge. The study has been designed for the purpose; to develop a concept for an interior lightning to the premium segments. Based on the purpose of the study, four questions were created which the study will be focused around.

    To answer these questions, the authors has chosen to use a concept study, where earlier literature used as the basis for the achievement. The decisions taken during the work has been based on theoretical background and previous methods. To get an overview of the market, a competitive analyses have been established.

    The study resulted in a number of concepts which then were concentrated into one final. The concept is adapted to Thule’s design language and perceived well integrated in the roof box. What makes the product attractive to the customers is particularly the increased functionality provided by an illuminated packing space. Because of the work to avoid a spotlight-feeling the final concept gives a more exclusive feeling.

    Further work and research within the study would include the attendance of interested companies for the refinement of concepts and finally a cost estimation to determine if a future production is of interest.

    Abstract [en]

    This report is a bachelor thesis work within the field of Product Development and is also an assignment for Thule Sweden. The work has been performed by Niclas Tjäderborn and Christian Holm, students at the Mechanical Engineering Program with major in Product Development and Industrial Design at Jönköping School of Engineering during spring the semester of 2009.

    The thesis work concerned the development of a new wheel holder for bike carrier for Thule Sweden. The background to the project was that the initiator wanted a more user friendly wheel holder with better design than those available on the market. The wheel holder is able to be implemented on one or several of Thule’s current wheel holders. The report continues the entire process from pre-study to the finished prototype. One of the challenges concerning the project was that the wheel holder should be able to attach bicycle wheels that have large variations in dimensions; due to this a specific investigation concerning dimensions was performed. A patent investigation was also made in order to find out what patents that currently exist. Seven different concepts with several versions have been developed during the project work, all of them created in CAD, specifically using Solidworks. After a four phase’s evaluation, one of these concepts was chosen. This final concept was further developed and a prototype was made in 3D-printer.    

    The authors of this thesis would like to thank everyone that has been a great help during the thesis work. A special thanks goes to Joakim Andersson and Anders Lundgren at Thule Sweden.

    Reducing internal lead times in MTO & job-shop production environments: a case study2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This Master’s thesis has been carried out within the subject area of Production Development and Management and aims to reduce internal lead times in make-to-order (MTO) and job-shop production environments with the use of identified theoretical methods.

    The reason this particular production environment was chosen was the flexibility and satisfaction it provides its customers. Today, customers expect customised products, a situation which causes problems for manufacturers as they are unable to produce such products in large amounts. In order to investigate problems with these kinds of environments and the causes for long lead times, we have conducted a literature study where we identified the problems these particular kinds of production environments experience regarding production planning and control which are related to the immense amount of time consumed by changeovers because of high demand variance and high requirements for customisation.

    To affirm the theoretical findings, we opted to undertake a case study and chose Talent Plastics Gislaved AB as our case, because this company utilises an MTO and job-shop production environment for its production of highly customised products with high demand variance. In the analysis of our case, we found that the wastes in the organisation were similar to those identified in the theoretical findings. The current planning system and the current state of the manufacturing lead time system were evaluated and a theoretical framework using a combination of lean production, work load control and constant work-in-process theories was suggested. We claim that concentrating on the reduction of setup times can lead the job-shop towards drastically decreased lead times and a much more effective use of time throughout the organisation.

    Because the organisation will continue to face problems due to the ever-increasing demand variance and requirements for customisation, there are plenty of opportunities for further research in these kinds of production environments. Emerging theories, such as quick response manufacturing, may also be tested to construct an efficient framework.

    Characterization of Fluid Flow in Continuous Casting through Physical and Numerical Modelling2020Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Continuous casting transforms molten metal into solid continuously and includes a variety of important commercial processes. Continuous casting is a relatively new process in historical terms. The metals like 500 million tons of steel, 20 million tons of aluminum, and 1 million tons of copper, nickel and other metals in the world, are mass-produced using a continuous casting process. Continuous casting generally has higher capital costs but lower operating costs. It is the most cost and energy-efficient method to mass-produce semi-finished metal products with consistent quality in a variety of sizes and shapes.

    The current thesis project aims to develop a 1:1 scaled water model for a continuous slab caster capable of predicting surface waves, including both wave magnitude and traveling depth — where the results obtained from the thesis work used to validate 3D numerical models developed in OpenFOAM CFD toolbox.

    In the water model, probes are used on both the left and right sides of SEN to study the flow velocities; the air injected into the SEN to visualize the flow pattern. Likewise, the LES model is used to simulate the flow pattern in the numerical model.  

    The results from the water model experiment are compared with the numerical model.

    Framework of Standardized Workstations for a Mixed-model Assembly Line: Material Presentation and Work Activities from a Time Efficient and Ergonomic Perspective2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose of the study is to propose a framework for standardized workstations with focus on operators work activities and material presentation on a mixed-model assembly line. In order to fulfill the purpose, it was decomposed into three research questions:

    Research question 1: What problems in existing manual workstations can be identified, regarding work activities and material presentation?

    Research question 2: What can be considered regarding operators' work activities in creation of standardized workstations for a mixed-model assembly line?

    Research question 3: What can facilitate the work performance and ergonomics of operators when designing material presentation for standardized workstations for a mixed-model assembly line?

    Methodology – This study was carried out inductively through analysis of empirical data from a case study against existing theories from a literature study. Theories were in the areas of mixed-model assembly line, workstation design, material presentation, work activities, ergonomics and human aspect, and standardization and flexibility. To gather empirical data, a document study, observations and interviews were conducted at one case company.

    Findings – The study resulted in a framework for work activities and material presentation in standardized workstations on a mixed-model assembly line within the perspectives of ergonomics, standardization and non-value-added work. Results indicated on decreased efficiency if the involvement of human factor and standardization were insufficient in the workstation design, by increased non-value- added work and decreased ergonomics.

    Implications – The proposed framework intended to support companies to merge assembly lines into a mixed-model assembly line with low automation.

    Limitations – The framework in this study only focused on workstations' workactivities and material presentation. Workstations are linked to more than these two areas therefore should more areas be included in merging assembly lines. This framework had the perspectives of ergonomics, standardization and non-value-added work, more perspectives should be considered in a merger.

    Foldable pedelec2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This master thesis project is about easier commuting in a more eco-friendly way thus a new foldable pedelec - pedal electric cycle was created. The idea is that the commuters are able to fold their bicycle to a convenient size and store it under the desk in the office, in a trunk of a car, or even brought on a bus if used as a connecting transport.

    It incorporates the latest ergonomic, safety, display and drivetrain features in combination with a sleek single-fork design. This enables the pedelec to be folded more conveniently and save additional space.

    To appeal to a wider range of users they are given the opportunity to choose their own colour codes and personalize their own foldable pedelec.

    Lean, simulation and optimization: A maturity model2017In: IEEE International Conference on Industrial Engineering and Engineering Management, IEEE, 2017, p. 1310-1315Conference paper (Refereed)
    Abstract [en]

    This article presents a maturity model that can be applied to support organizations in identifying their current state and guiding their further development with regard to lean, simulation and optimization. The paper identifies and describes different maturity levels and offers guidelines that explain how organizations can grow from lower to higher levels of maturity. In addition, it attempts to provide the starting point for organizations that have applied lean or are willing to implement it and which may also be considering taking decisions in a more efficient way via simulation and optimization.

    Improving the material flow of a manufacturing company via lean, simulation and optimization2017In: IEEE International Conference on Industrial Engineering and Engineering Management, IEEE, 2017, p. 1245-1250Conference paper (Refereed)
    Abstract [en]

    Companies are continuously working towards system and process improvement to remain competitive in a global market. There are different methods that support companies in the achievement of that goal. This paper presents an innovative process that combines lean, simulation and optimization to improve the material flow of a manufacturing company. A description of each step of the process details the lean tools and principles taken into account, as well as the results achieved by the application of simulation and optimization. The project resulted in an improved layout and material flow that employs an automated guided vehicle. In addition, lean wastes related to transport, inventory levels as well as waiting times were reduced. The utilization of the process that combines lean, simulation and optimization was considered valuable for the success of the project.

    An exploratory study of the link between investment in transportation infrastructure and disaster impact2014In: NOFOMA 2014 Proceedings: Competitiveness through Supply Chain Management and Global Logistics / [ed] Britta Gammelgaard, Günter Prockl, Aseem Kinra, Jesper Aastrup, Peter Holm Andreasen, Hans-Joachim Schramm, Juliana Hsuan, Malek Malouf, Andreas Wieland, Department of Operations Management, Copenhagen Business School , 2014, no 1Conference paper (Refereed)
    Abstract [en]

    Purpose of this paper 

    Disasters affect millions of individuals each year and the current trend shows an increase in these numbers. The aim of this paper is to explore whether investments in transportation infrastructure in areas affected by disasters has a link with the number of people affected by disasters. 

    Design/methodology/approach

    Drawing on disaster models from the existing literature, the paper uses a regression model with secondary data about investment from 2005-2010 to explore the link between transport infrastructure investment and people affected by disasters in 2011.

    Findings 

    The multivariate model presented in this paper shows that there is a significant link between the investments made in transport infrastructure and a reduction of the number of affected people in disasters. 

    Research limitations 

    The research and model of this paper is limited by its sample size as well as by the secondary data which does not record all transportation investments made by governments but only the ones made through World Bank projects. Practical implications The results help understand what could be one of the many drivers behind reducing the amount of people affected by disasters. The results can further be used by policy and decision makers to take knowledgeable decisions when investing in disaster prone countries. 

    Originality of paper 

    This paper is original since it looks at a new variable that has not been studied previously and that might affect disaster outcomes.

    Country logistics performance and disaster impact2015In: Disasters. The Journal of Disaster Studies, Policy and Management, ISSN 0361-3666, E-ISSN 1467-7717, Vol. 40, no 2, p. 262-283Article in journal (Refereed)
    Abstract [en]

    The aim of this paper is to deepen the understanding of the relationship between country logistics performance and disaster impact. The relationship is analysed through correlation analysis and regression models for 117 countries for the years 2007 to 2012 with disaster impact variables from the International Disaster Database (EM-DAT) and logistics performance indicators from the World Bank. The results show a significant relationship between country logistics performance and disaster impact overall and for five out of six specific logistic performance indicators. These specific indicators were further used to explore the relationship between country logistic performance and disaster impact for three specific disaster types (epidemic, flood and storm). The findings enhance the understanding of the role of logistics in a humanitarian context with empirical evidence of the importance of country logistics performance in disaster response operation

    Konceptstudie av gräsuppsamlare2018Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    This report describes the degree project by Oscar Gustavsson and Sulaymon Valizoda during the spring term 2018 at School of Engineering in Jönköping. The thesis has been carried out for Husqvarna AB in cooperation with Semcon AB as a final part of the authors’ education to engineers in Mechanical Engineering, Product development and Design. Within the company Husqvarna AB development and renewal are of great interest. In their development of grass collectors, this mission was assigned where the goal was to create new concepts and solutions to a grass collector belonging to one of Husqvarna AB's existing walk behind lawn mowers. The aim was to reduce the amount of spilled grass that lands on the ground and making it easier for the user to empty the collector after the grass has been collected. The work has been carried out as a concept study where a selected product development process has been implemented. The different phases and methods of the process from pilot studyto prototype are described to clarify how their approaches have been used. During the project a requirement specification was defined which specifically described what would be fulfilled and which could be followed as a basis in the development of concepts. To give this thesis a theoretical background, theories about the product development process, computer-aided design, vacuum forming, steel and welding joints has been applied.The study resulted in a final concept that were further developed and prototyped. The concept was considered by Husqvarna AB to be the best concept to proceed with.Testing and evaluation were performed on the prototype where the work was limited to. Further more, Husqvarna AB is able to continue the development and use the information from the work, which hopefully can be a helpin the development of a better grass collector.
