    Effektivisering av en produktionsprocess: En fallstudie på Corroventa AB2019Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    En pågående fråga för företag idag är möjligheten att leverera ett brett sortiment av produkter, med kort ledtid och till låg kostnad. Det innebär att större krav ställs på att företagen ska ha en hög produktmix- och volymflexibilitet samtidigt som de håller hög effektivitet. För att uppnå detta krävs att företagen bland annat belyser de okända förlusterna i sin organisation och produktionsprocess för att sedan minimera dessa.

     

    Denna studie har tagit plats på ett industriellt företag som heter Corroventa avfuktning AB och är beläget i Bankeryd, Sverige. De specialiserar sig bland annat på produkter som används för att avfukta byggnader och neutralisera radonstrålning.

     

    Företaget producerar i huvudsak mot lager, väderförhållanden som skapar översvämningar och fuktskador kan driva upp efterfrågan till en punkt som företaget inte kan uppfylla med en tillräckligt kort ledtid för att vinna kundorder. Detta sätter press på Corroventa till att effektivisera och utveckla produktionen för att öka flexibiliteten och minska ledtiden.

     

    Fallstudien har genomförts på en avdelning som kallas för insatsmontering, denna avdelning är en förmonteringsenhet till slutmontering av produkten adsorptionsavfuktare. Avdelningen har identifierats som en begräsning för hela systemet när hög efterfrågan råder, därför har undersökningen utförts för att identifiera de underliggande problemen som orsakade begräsningen och ge förbättringsåtgärder på dessa.

     

    Med en nulägesanalys och ett teoretiskt ramverk som grund har författarna identifierat områden på avdelningen som kan effektiviseras. Rekommendationsförslagen inkluderar en ny produktionslayout, en mer balanserad monteringsprocess samt en minskning av materialhanteringen. Dessa förslag kommer att förbättra avdelningens produktmix- och volymflexibilitet samtidigt som ledtiden reduceras.

     

    Som ett sista steg har en diskussion och slutsats skrivits för att diskutera studiens validitet och reliabilitet, därefter sammanfattas förbättringsförslagen och föreslagna framtida studier som kan genomföras för att ständigt förbättra verksamheten.

    Developing a line balancing tool for reconfigurable manufacturing systems: A tool to support investment decisions2021Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Purpose - This thesis aims to developing a decision-making tool which fits in a reconfigurable manufacturing system (RMS) milieu used to identify whether to introduce and produce a new product into an already existing assembly line or to invest in a new assembly line. To fulfil the purpose, four research questions were developed. 

    1. Which line balancing problem-solving techniques exist in the literature?
    2. Which investment costs can be considered vital for new assembly lines as a    consequence from new product introductions?
    3. Can a decision-making tool be designed to evaluate new product introductions which considers both line balancing KPIs and investment costs in an assembly line?
    4. To what extent can criteria in the RMS theory be linked with the attributes of the    designed decision-making tool to support its applicability?

    Method - Literature studies were performed in order to create a theoretical foundation for the thesis to stand upon, hence enabling the possibility to answer the research questions. The literature studies were structured to focus on selected topics, including reconfigurable manufacturing systems, line balancing, and assembly line investment costs. To answer the third research question, which involved creating a decision-making tool, a single-case study was carried out. The company chosen was within the automotive industry. Data was collected through interviews, document studies and a focus group.

    Findings & analysis - An investigation regarding which line balancing solving-techniques suit RMS and which assembly line investment costs are critical when  introducing new products has been made. The outputs from these  investigations set the foundation for developing a decision-making tool which enables fact-based decisions. To test the decision-making tool’s compatibility with reconfigurable manufacturing systems, an evaluation against established characteristics was performed. The evaluation identified two reconfigurable manufacturing system characteristic as having a direct correlation to the decision-making tool. These characteristics regarded scalability and convertibility.

    Conclusions - The industrial contribution of the thesis was a decision-making tool that enables fact-based decisions regarding whether to introduce a new product into an already existing assembly line or invest in a new assembly line. The academic contribution involved that the procedure for evaluating the tool was recognized as also being suitable for testing the reconfigurable correlation with other production development tools. Another contribution regards bridging the knowledge gaps of the classifications in line balancing-solving techniques and assembly line investment costs.

    Delimitations - One of the delimitations in the thesis involved solely focusing on developing and analysing a decision-making tool from an RMS perspective. Hence, other production systems were not in focus. Also, the thesis only covered the development of a decision-making tool for straight assembly lines, not U-shaped lines.

    Abstract [en]

    Case studies and modeling of logistics systems are the basis for the formulation of the content and structure of a reference model for the organization and management of Value Networks as a higher stage of integrated development of supply chains. The definition of a mathematical model for the balance of the Value Network can reveal the characteristics and principles of organization and management of Value Networks.The instrument obtained enables supply chains to assess their level of development and identify the characteristics that should be developed to reach the concept of Value Network, which is based on knowledge development and environmental integration as supports of the same and its competitive position in the global market.

    Proper integration into the model of environmental factors ensures that Value Networks are inserted into the objectives of promoting sustainable development. The current concept of logistics flow is extended to incorporate within it the exchange of energy, resources and impacts to the environment.

    The research methods used were based on a combination of study and experimentation of cases and the conceptual and mathematical modeling of systems.

    Automatic generation of fuzzy inference rules in a reshoring decision context2019Ingår i: Proceedings of the 9th International Conference on Operations and Supply Chain Management, Vietnam, 2019, OSCM , 2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents a decision-support system for reshoring decision-making based on fuzzy logic. The construction and functionality of the decision-support system is briefly outlined and evaluated in a highcost environment contemplating six specific decision criteria, namely cost, quality, time, flexibility, innovation and sustainability. A major challenge with fuzzy logic solutions has to do with the construction of the fuzzy inference rules. In the relocation domain, the fuzzy inference rules represent the knowledge and competence of relocation experts and they are usually created manually by the same experts. One obstacle is that the complexity of the fuzzy inference rules increases with the number of decision criteria. To overcome this complexity issue, this paper presents a solution whereby the fuzzy inference rules are automatically generated by applying one hundred reshoring scenarios as input data. The reshoring decision recommendations produced by the fuzzy logic decision-support system are demonstrated to be close to those of human reshoring domain experts.

    Semi-Automatic Generation of a Fuzzy Inference System in a Reshoring Context2020Ingår i: SPS2020: Proceedings of the Swedish Production Symposium, October 7–8, 2020 / [ed] K. Säfsten & F. Elgh, IOS Press, 2020, Vol. 13, s. 599-609Konferensbidrag (Refereegranskat)
    Abstract [en]

    Reshoring can be regarded as offshoring in reverse. While offshoring mainly has been driven by cost aspects, reshoring considers multiple aspects, such as higher quality demands, faster product delivery and product mass-customization. Where to locate manufacturing is usually a purely manual activity that relies on relocation experts, hence, an automated decision-support system would be extremely useful. This paper presents a decision-support system for reshoring decision-making building a fuzzy inference system. The construction and functionality of the fuzzy inference system is briefly outlined and evaluated within a high-cost environment considering six specific reshoring decision criteria, namely cost, quality, time, flexibility, innovation and sustainability. A challenge in fuzzy logic relates to the construction of the so called fuzzy inference rules. In the relocation domain, fuzzy inference rules represent the knowledge and competence of relocation experts and are usually generated manually by the same experts. This paper presents a solution where fuzzy inference rules are automatically generated applying one hundred reshoring scenarios as input data. Another important aspect in fuzzy logic relates to the membership functions. These are mostly manually defined but, in this paper, a semi-Automatic approach is presented. The reshoring decision recommendations produced by the semi-Automatically configured fuzzy inference system are shown to be as accurate as those of a manually configured fuzzy inference system.

    Abstract [en]

    The purpose of this paper is to identify critical factors forcing manufacturing companies to improve the development of production technology in a machining environment. The focus in the paper is on industrial challenges within product design and production system development when introducing new products in a machining environment. Particular attention is given to the product development process and the production equipment acquisition process. A single case study is presented, consisting of interviews, observations, document studies and an analysis of a large Swedish manufacturing company. The case study company is characterized by advanced production technology, high mechanization and high automation level. In parallel with the case study a literature review was conducted in order to identify state-of-the-art methods/models for efficient design and product introduction within a production system. The paper identifies a gap in the current way of working within the case company as well as challenges regarding the development of production technology. Based on the study, the need for future research has been identified including the need of developing an improved working support for efficient production technology development when industrializing new products.

    The fuzzy front end of manufacturing technology development2019Ingår i: International Journal of Manufacturing Technology and Management (IJMTM), ISSN 1368-2148, E-ISSN 1741-5195, Vol. 33, nr 5, s. 285-302Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The fuzzy front end of product development has been studied extensively in previous research, while the fuzzy front end of manufacturing technology development has been largely neglected despite its importance. Only a few empirical studies that examine the fuzzy front end of manufacturing technology development can be found, which have been primarily carried out in the process industry. Therefore, the overall purpose of this paper is to explore the fuzzy front end of manufacturing technology development. Based on three case studies carried out in the manufacturing industry, the findings of the current research highlight key activities in the fuzzy front end of manufacturing technology development and suggest that the fuzzy front end has four sub-phases with overlapping development activities.

    Manual Assembly Improvement In Make to Order Production2015Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    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 Japan2013Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    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.

    Barriers and Enablers for the Adoption of Sustainable Manufacturing by Manufacturing SMEs2022Ingår i: Sustainability, E-ISSN 2071-1050, Vol. 14, nr 4, artikel-id 2364Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Small-and medium-sized enterprises (SMEs) have inherent characteristics, which require specific solutions for improving the sustainability performance of their operations. The purpose of this paper is to increase the knowledge on barriers and enablers for the adoption of sustainable manufacturing by manufacturing SMEs and to provide insights into what enablers can be used to overcome existing barriers. Taking, as a starting point, a systematic literature review, this paper presents a categorization of barriers and enablers for the adoption of sustainable manufacturing by manufacturing SMEs. In total, seven categories for classifying the barriers and enablers for the adoption of sustainable manufacturing within SMEs were identified: organizational, managerial and attitudinal; informational; governmental; financial; training and skills development; market and business context; and technological. Additionally, this study elaborates on what barriers could be mitigated through the enablers. This study found specific enablers with the potential to mitigate a significantly higher number of barriers and referred to them as ‘critical enablers’. SMEs aiming to adopt sustainable manufacturing practices or improve their sustainability performance are encouraged to focus on the enablers in these categories. This paper synthesizes and facilitates interpretation of the existing body of evidence on barriers and enablers for adopting sustainable manufacturing in SMEs.

    A framework for enabling operators to use simulation for continuous improvement2022Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    In a time where digitalization is becoming more and more necessary to work with, tools such as simulation is becoming more of a standard to be able to make decisions made on facts. Within previous research there is a gap in the research, as the factors enabling operators to use simulation is an unexplored topic. Therefore, to fill this gap and provide the industry with help, this study fulfills the purpose: 

    Create a framework for enabling operators to use simulation for continuous improvements. 

    By looking at the different areas in the production and identifying challenges within the production, information handling between the departments and the structure of the company, the purpose of this study is fulfilled. The purpose was achieved through the usage of two research questions. 

    What are the challenges in practice for enabling operators to use simulation for continuous improvements? 

    How can these challenges be overcome, to enable operators to use simulation for continuous improvements? 

    To answer the research questions, a case study was performed alongside a literature review. The case study consisted of interviews performed at a case company within the automotive industry. The gathered empirical and theoretical data was then analyzed trough a thematic analysis. 

    The conclusion of this study was that, for enabling operators to use simulation for continuous improvements, companies must first have the right organizational structure, were a foundation for continuous improvement is present. The reason for this being that if a company desires to work with simulation tools, they must first work in an environment where suggestions and improvements are supported.

    Improving an internal material handling system. A case study of a Swedish company in food industry2020Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Currently, customers are exerting a lot of pressure on companies by demanding for best product quality, customized products, reduced product lead time and reliable product delivery. Therefore, for companies to be highly competitive, there is need to improve productivity and delivery performance by having an efficient material flow. Nevertheless, the task of making the material to flow efficiently throughout the manufacturing process up to when the customer receives the product is not easy. To solve this, companies are focusing on the material handling system as it has an impact on efficient material flow and productivity. Hence, the aim of this project was to explore how an internal material handling system can be improved to guarantee a better delivery performance.

    To fulfil the aim, a single case study was undertaken at a dairy food producing company in Jonkoping. The information on the subject area was obtained through interviews, observation at the company and an extensive literature review. The information that was obtained was assessed in accordance with the framework of the project that includes; principles and physical elements used for designing a material handling system, software and information, and human and management.

    Combined analysis of the findings from the empirical study and the extensive literature review helped to identify the problems faced in an internal material handling system of the company. This was followed by identifying ways of improving material handling system and thereafter, improvement suggestions were made targeting enhancement of the delivery performance of the system.

    In conclusion, the findings indicate that improvement of an internal material handling system does not only depend on improving the physical attributes of the system, far from it, it is more dependent on having an efficient and effective information system. Another factors that came out is that there should be a proper integration of the material handling system and the workers operating the system. From a systems perspective this research has added information sharing and human and management to the one dimensional physical elements improvement of a material handling system.

    Analys av monteringslinan för luftbehandlingsaggregat (EC)2006Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats
    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.

    Standardization in a High Mix Low Volume Company: A Case Study2020Självständigt arbete på avancerad nivå (masterexamen), 80 poäng / 120 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The market has been evolving from mass production towards mass customization, which has increased the complexity level for the companies. Unlike in mass production companies where the tasks are routine and standardized, the mass customization types of companies have a varied work demand which makes the work environment complex. These types of mass customization companies are known as High Mix Low Volume type of companies basically because of their characteristics of having a high mix in products and comparatively low volume production. 

    This thesis research was done with DEWTON INDUSTRIES, Kochi in India. Although product variety and complexity has been answered using technology development and modularization in the previous studies, there has been less focus given to reducing the complexity from the production process point of view. It is also evident that there is limited literature and research done regarding the standardization in High Mix Low Volume type companies both in the academia and in the industry. Hence, understanding the problems regarding standardization in a High Mix Low Volume company and how to handle them has been of a major importance at this point of time.

    The purpose of the research is to see how standardization can be increased in HMLV companies. The research approach used here was the case study to collect the necessary data to achieve the results. The data collection techniques used were interviews, observations and literature review, which gave the guidelines and suggested solutions to the identified problems related to standardization in High Mix Low Volume company in the production department. 

    The findings from the research suggest that standardization in HMLV production is very important for the companies in their current market demands. This is because standardization has a major effect on the quality of end products, production lead time, working standards of employees in the production department and design department. Various problems can occur, and only standardized procedures can solve these problems. It has been well exemplified in this thesis work, how these standardized procedures can increase the quality of the products, increase production speed, and also profit for the company.

    This research paper can be used as a guideline by other HMLV companies, while they plan to implement standardization in the production department. To the best of our knowledge this research was one of a kind in this particular field of study and also provides a base for in-depth research on each identified problem.

    Simulation of Assembly cell: Simulation based evaluation of automation solutions in an assembly cell2021Självständigt arbete på avancerad nivå (masterexamen), 30 poäng / 45 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Purpose:The primary purpose of the current thesis is to develop a virtual model using discrete event simulation (DES), which aims at supporting the decision-making process regarding automation solution proposals for SMEs. 

    Method:The research approach is positivism, and it considers quantitative and empirical information. A literature search is conducted to generate a base for obtaining the theory required for the current report to answer the research questions. This search included the trace of relevant and reviewed topics regarding automation, discrete event simulation, and production lines. Then, a scenario simulation is designed and studied based on empiric knowledge and how automation would affect it, followed by a collection of information from the simulation iterations.

    Findings& Analysis: Two scenarios are presented. One with a fully manually operated assembly line consisting of only human operators and a second scenario, a semi-automated assembly line that includes some robots in specific areas doing specific operations. The two scenarios are simulated to check to what extend the KPI’s and parameters improved between each scenario. The experiment result concludes that by introducing automation elements in the production line, there is an increase in the overall efficiency, throughput rate, and a considerable gap against humans in WIP.

    Conclusions and recommendations: The results obtained from the experimentation in discrete event simulation software and study from previous research show that discrete event simulation has a significant contribution when considering a decision-making tool's role. Since it allows to understand and study the specific scenario by imitation and try different solutions in the same production system, it also allows studying several indicators from the scenarios to be checked to what extent they could be improved.

    Delimitations: The current thesis includes several delimitations. First, it focuses only on an operational level. Also, this study consists of a specific type of product with many variants, and finally, there are only two scenarios studied: a fully manual scenario and a semi-automated scenario with the presence of robots.

    A Study of the Effects of Operational Time Variability in Assembly Lines with Linear Walking Workers2012Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    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.

    Methodology for Obtaining S-N Curves using Fatigue Testing and Static FEA2022Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The use of recommended S-N curves, presented in current literature, to analyse and determine the fatigue life of a part is common practice in, inter alia, the construction industry.However, the recommended S-N curves are generally created for larger components used in mainly the construction industry. Hence, the use of S-N curves for the evaluation of smaller parts, may result in over-dimensioning of such parts. For this reason, evaluation and designing of smaller parts could benefit from the development of an in house S-N curve specific for the part.

    The purpose of this thesis is to generate and validate an in-house method for creating a S-N curve, for a specific part to be compared with recommended S-N curves in the literature. The specific part used for the generating of the method is a welded steel joint with the geometry of two steel pipes, welded together in a t-formation and which has been provided by Thule AB for the purpose of the thesis.

    The method presented uses the results from 1) physical fatigue tests using a fatigue testing machine and 2) static FEA to derive a S-N curve for the specific part using the least squares method. A fatigue testing rig enables the gathering of data of the number of cycles to failure when the part is subject to a given cyclic load. The rig uses pneumatics to control the forces applied onto the part with the use of a cylinder. Furthermore, the fatigue testing rig was designed to be controlled by the applied force, meaning, that the rig ensured a homogeneous load cycle by measuring the force from a load cell and alternating the direction of the cylinder with an electrically controlled pressure valve. The performance of static FEA evaluations aim at locating stresses in the part. For this thesis the stresses were evaluated using the hot spot method due to the part's welded geometry.

    The data gathered from the physical fatigue tests and the static FEA evaluations are subsequently combined deriving S-N curves applicable to the part.

    From the fatigue tests and FEA evaluations for the t-shaped welded steel part, four S-N curves were derived of which two curves showed the results of a linear fitted curve whereas the other curves used the recommended slope of $-1/3$. The results showed that the S-N curves derived, using a set slope, resulted in similar curves to the recommended S-N curve provided by the literature. However, the linear fitted S-N curve showed that the part, according to the S-N curve, had a higher fatigue resistance than recommended.

     Due to limitations in the thesis work, the S-N curves derived within the framework of this thesis should be regarded as theoretical and have been strictly used to identify whether the method generated is applicable for deriving of S-N curves.

    Abstract [en]

    Changeability and reconfigurability are some of the most important sources of competitiveness in today's manufacturing industry. However, the development and implementation of reconfigurable manufacturing systems still appear to be challenged and limited in industry. Therefore, it is increasingly relevant for engineers and professionals in the manufacturing industry to build knowledge and competences in reconfigurability. This paper presents preliminary insights and learnings from developing and running a problem-based learning (PBL) course in reconfigurable manufacturing for continuing engineering education (CEE). Presented insights cover both observed benefits and learnings for professionals participating in the course, as well as important learnings on how to best transfer knowledge from research to practice.

    Towards a generic design method for reconfigurable manufacturing systems: Analysis and synthesis of current design methods and evaluation of supportive tools2017Ingår i: Journal of manufacturing systems, ISSN 0278-6125, E-ISSN 1878-6642, Vol. 42, s. 179-195Artikel i tidskrift (Refereegranskat)
    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.

    Investigating the Transition towards Changeability through Platform-based Co-development of Products and Manufacturing Systems2019Ingår i: 7Th International Conference On Changeable, Agile, Reconfigurable And Virtual Production (Carv2018) / [ed] C. DaCunha, A. Bernard, M. Zah, H. ElMaraghy, W. ElMaraghy, Elsevier, 2019, Vol. 28, s. 114-120Konferensbidrag (Refereegranskat)
    Abstract [en]

    Increasing product variety, rapid new product introductions, volatile market demands, and pressure for cost reductions are among the main drivers for developing changeable and reconfigurable manufacturing systems constituting platforms that can be developed and utilized jointly with product platforms. However, methodologies to support platform-based co-development of products and manufacturing systems remain limited in previous research, including lack of knowledge on successful practices for the platform-based co-development project and process. Therefore, the objective of the research presented in this paper is to identify practices for platform-based co-development of products and manufacturing systems through a case study of a company that has successfully transitioned towards changeability through platform-based co-development. The findings cover various aspects of the co-development process and project, providing initial insight into how to enable joint development of products and manufacturing systems, in order to achieve changeability and reconfigurability.

    Reconfigurable Manufacturing - An Enabler for a Production System Portfolio Approach2016Ingår i: Procedia CIRP, Elsevier, 2016, s. 139-144Konferensbidrag (Refereegranskat)
    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 Asia2015Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    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.

    Betydelsen av tillförlitligt underlag vid identifiering av förluster: En fallstudie om förbättringsarbete från ett underhållsperspektiv2021Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    In order to work with continuous improvements and be competitive on the market, it is important that companies identify where their losses are [1]. A suitable way to identify losses is by using measurements [2] and with today’s information technology, it is easier than ever to collect data [3]. The problem is not that companies do not measure performance at all, they measure too much [4]. The study has been made at a producing company who stated that they do not reach their desired amount of availability in the production. There is no information on what their biggest losses are today and there is a lack of a systematic approach to reduce them. There is either any information on how much time that is used on maintenance activities or the distribution between operator maintenance or specialist maintenance. The study’s questions are following: 

    [1]   What can be determined and what conclusions can be drawn from existing data from the company’s industrial system and maintenance system? 

    [2]   Can a suggestion on a systemized working method be identified for working with availability losses for the case company? 

    Theories about operational reliability, maintenance technology, PDCA and the cornerstone model has been used to answer the study’s questions. Quantitative and qualitative data collections has been used to analyze the results from the company’s industry- and maintenance systems. Qualitative interviews have been made with affected personnel. 

    The cause of the company’s losses in the industry system cannot be identified as the data does not reflect the reality. The reason for that is the lack of standardized way of working when availability losses are registered. In the maintenance system, the structure of how cases are registered is lacking and the sectioning between operator maintenance and specialist maintenance is unclear. 

    The study’s proposed action is to create conditions for the case company to make their data more reliable and how they can reduce their availability losses. This is done by standardizing the work method in the industrial system, introducing a new structure for how the maintenance system is used and structured working methods between operators and maintenance personnel. The entire study results in a model on how to be able to identify losses and how they systematically can be reduced.

    Managing Successful Change Initiatives: An Investigation of Critical Success Factors for Six Sigma Introduction in Large Manufacturing Enterprises in Sweden2023Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Six Sigma is one of the most successful improvement strategies of the last 5 decades and has been implemented worldwide by organizations in different sectors and sizes. Despite the popularity, 60% of all Six Sigma initiatives are abandoned or end in failure. Therefore, the purpose of this thesis is to investigate what factors large manufacturing enterprises in Sweden need to prioritize to introduce Six Sigma successfully. The research was conducted as a holistic multiple-case study where qualitative data was collected through semi-structured interviews with three companies. A thematic analysis was made to identify patterns between the companies about critical success factors associated with Six Sigma, Change Management, and Organizational culture. It was shown that Company 1 has introduced Six Sigma but has no defined plan on how to move forward with the initiative. Company 2 has fully introduced the method and is actively working with it, while Company 3 has failed with the introduction of Six Sigma. All identified factors were rated as either a success or a failure factor for each case company. The success factors differentiating Company 2 from the other case companies have been evaluated to be the most critical success factors. Top management commitment, Organizational support, Organizational culture, Communication, and Strategic plan have been identified as the most critical success factors that must be prioritized to introduce Six Sigma successfully. Furthermore, cultural factors such as communication between departments, supportive managers, and committed top management have been identified as important to introduce Six Sigma successfully. The results of this study can be applied to successfully introduce change initiatives in large manufacturing enterprises in Sweden.

    Utredning av stopptider i ett täcklacksmåleri verksamt inom fordonsindustrin2019Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Syftet med följande studie är att undersöka och analysera stopp och dess rotorsaker som uppkommer i buffertsystemet på ett täcklacksmåleri. Utifrån denna utredning presenteras sedan åtgärdsförslag i syfte att eliminera undersökta stopp. För att kunna uppfylla syftet med studien har följande frågeställningar formulerats:

     

    1. Vad finns det för stopp relaterade till buffertsystemet och vad är rotorsakerna till dessa?
    2. Hur mycket kan det akuta underhållet reduceras?
    3. Hur stora besparingar skulle företaget kunna göra genom reducering eller eliminering av stoppen?
    4. På vilket sätt kan en minskning av stoppen öka tillgängligheten för täcklacksmåleriet?

     

    En fallstudie har genomförts där historisk data har analyserats och personal från avdelningar som produktion, underhåll och IT har intervjuats. Den empiri som samlats in tillsammans med det teoretiska ramverket som presenteras i rapporten ligger till grund för resultatet, analysen och åtgärdsförslagen.

     

    Resultatet från studien visar att en stor andel av de stopp som sker i buffertsystemet orsakas av mjuka förluster. Dessa stopp är en konsekvens av bristfällig hantering av data och mjukvara samt bristfällig kommunikation mellan verkstäderna. Konsekvenserna av dessa stopp resulterar i ökade kostnader samt en nedsatt effektivitet för täcklacksmåleriet. Åtgärdsförslagen som presenteras ger företaget goda möjligheter att uppnå sin fulla kapacitet, eliminera stoppen och därmed öka effektiviteten.

     

    Studien är avgränsad till måleriprocessen och omfattas inte av grundmåleriet eller monteringen. De resultat, analyser och åtgärdsförslag som presenteras är avgränsade till de mjuka förlusterna som orsakar stopp i buffertsystemet.

    Effektivisering av två monteringslinor ur ett produktivitetsperspektiv2013Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Hur kan två automatiserade monteringslinor effektiviseras för att öka antalet färdigmonterade produkter i timmen? Denna fråga ställdes inledandevis vid utformningen av detta examensarbete, som är gjort i samarbete med företaget Thule Sweden AB (Thule). Bakgrunden till detta examensarbete är att Thule anser att två av deras monteringslinor inte når sin fulla kapacitet. Utifrån bakgrunden kom syftet att öka antalet färdigmonterade produkter per timme för respektive monteringslina. För att besvara syftet formulerades tre frågeställningar; Hur kan monteringstakten öka genom kortare upptäcktstider vid larm? Vilka rutiner kan implementeras för att skapa förutsättningar till ökad monteringstakt? Finns det möjlighet till ytterligare ökad monteringstakt? För de båda linorna finns ett mål uppsatt om hur många paketerade kartonger (fyra produkter per kartong) som ska göras i timmen, 90 respektive 100 stycken.

    För att besvarar frågeställningarna och på så vis uppfylla arbetets syfte har datainsamling i form av tidsstudier, observationer och samtal genomförts. Datainsamlingen har sedan analyserats för att skapa en bild av nuläget. Nulägesbeskrivningen ligger sedan till grund för förbättringsarbetet.

    Gällande lina X ansågs den största förbättringspotentialen finnas i linans larmsystem. I dagsläget tar det drygt 20 sekunder för operatörerna att upptäcka larmen. Upptäcktstiden påverkar antalet färdiga kartonger i timmen genom att utrustningen står stilla på grund av att operatörerna är omedvetna om larmen. Upptäcktstiden går troligtvis att sänka genom investeringar i larmsystemet. Under förutsättning att upptäcktstiden sänks till noll sekunder ökar monteringstakten med nästan tio kartonger per timme. Med en upptäcktstid på noll sekunder samt andra förbättringar kan monteringstakten öka med totalt 14,3 kartonger per timme.

    Lina Y:s larmsystem är annorlunda i jämförelse med det som finns på lina X. Upptäcktstiden vid lina Y är endast en sjättedel av upptäcktstiden för lina X, därför ansågs det viktigare att lägga större vikt vid att förbättra andra problemområden. För att förbättra en manuell monteringsstation gjordes en SAM-analys på en ny monteringsmetod. SAM-analysen visade att monteringstiden kan minskas från 8,45 sekunder till 7,37 sekunder. Det finns också en automatiserad station med 8,35 sekunders operationstid. Lyckas Thule reducera denna tid till en operationstid under 7,37 och att den nya monteringsmetoden implementeras kommer de få ut 15,6 fler kartonger per timme. Genomförs också övriga förbättringsförslag kommer monteringstakten öka med ytterligare 7,8 kartonger per timme.         

    Slutsatsen för detta examensarbete är att det går att öka antalet färdigpaketerade kartonger med 14,3 respektive 23,4 kartonger i timmen. Detta förutsatt att Thule implementerar de förslag som tagits fram.

    Lean Produktion inom prefabindustrin2015Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Examensarbetet utfördes på Kynningsrud Prefab AB i Uddevalla som tillverkar prefabricerade betongelement till byggindustrin. I dagsläget är företaget inte helt tillfredsställt med material-, produkt-, information- eller kommunikationsflödet i verksamheten. Kynningsrud vill därmed skapa ett eget produktionssystem, KPS, för en fortsatt expansion.

     

    Genom diskussion med företaget beslutades att arbetet skulle fokusera på tillverkningen av väggelement. Syftet med arbetet är att analysera och identifiera förbättringsmöjligheter samt ta fram förbättringsförslag med förhållningssättet lean produktion.

     

    För att eliminera icke värdeadderad tid, standardisering av arbetsmoment samt informationsspridning valdes de sju slöserierna+en och 5S verktyget som teoretiskt ramverk. Information om verksamheten samlades in genom observationer, intervjuer och deltagande. Genom en nulägesbeskrivning av väggproduktionen med tillhörande stödprocesser beskrevs  arbetsmoment i processerna. Beskrivningen analyserades sedan efter det teoretiska ramverket.

     

    Analysen resulterade i åtta förbättringsförslag som tillsammans skulle eliminera slöserier med en total tidsåtgång på ungefär 12 timmar om dagen. Det innebar en kostnadsreduktion på cirka 3,500 kr per dag. Sammanställning av den insamlade informationen åskådliggjordes genom en GAP-analys.

     

    Vid tid- och kostandsberäkningar används den lägst uppskattade tidsåtgången från observationer och intervjuer med personalen som därmed kan innehålla mörkertal. Det gör att de beräkningar som redovisas är i teorin lägsta besparingen som kan genomföras. Kostnadsreduceringen kan i verkligheten vara större vid  en implementering av förbättringsförslagen.

    Quality-driven logistics2007Licentiatavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The overall objective of this thesis is to describe and explain how different quality management philosophies can be combined in the supply/demand chain, in order to contribute to its resilience. The analysis is both quantitative and qualitative, based on theory and literature related to TQM, Lean, Agile and Six Sigma, one literature study and three case studies that were performed in companies. The studies are related to four research questions and are presented in four papers. The first research question focuses on similarities and differences between the quality management concepts TQM, Lean and Six Sigma. The findings were that TQM, Six Sigma and Lean have many similarities, but they differ in some areas. For examples Lean addresses process flow and waste, whereas Six Sigma addresses variation and design. The conclusion is that there is a lot to gain if organisations are able to combine these three concepts, as they are complementary. Two case studies and a literature survey supported the findings. The second research question focuses on outcomes in a logistics process if using quality management. The findings were that the quality management approach leads to risks being mitigated, managed and monitored and ensures a more effective, robust and flexible process, very much in line with the Agility philosophy. Solutions for quicker response to customers have also been introduced. The findings were supported by two case studies in seven companies. The third research question focuses on how prepared the transport- and logistics-oriented companies are for the application of quality concepts and quality management philosophy. The findings were that they can be described as being TQM-oriented. The companies do not consider Lean and Six Sigma to be future trends. Focus is on the customer, while they do not focus on variations or removing waste. The findings were supported by a case study in 24 companies. The fourth research question focuses on how quality concepts can contribute to risk control and resilience in an organisation. A combined Lean/Six Sigma approach by using Six Sigma framework and the last phase, Perfection, in the Lean concept, implies that the companies’ resilience, due to their strengthened ability to handle variability, risk management and agility, was improved. The findings were supported by two case studies in seven companies.

    Supply chain resilience through quality management2009Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    The length and complexity of the supply chain tend to increase, rather than diminish, thereby making the supply chain riskier and less predictable and, hence, more vulnerable. At the same time, customers are becoming increasingly demanding. The challenge to businesses today is to create a resilient supply chain in order to manage and mitigate risk and vulnerability. The purpose of the thesis is to explore, describe and develop the use of a combined quality management philosophy in logistics processes in order to improve supply chain resilience. The findings are supported by six studies, which are presented here in six papers. The studies show that there is a lot to gain if organisations are able to combine quality management philosophies, as they are complementary to one another. TQM places its strongest emphasis on the commitment and involvement of all employees. Lean is a discipline that focuses on process speed and removal of waste in order to increase customer value. Six Sigma benefits from an added focus on variability and design of products/services and processes. It has been indicated that a combined quality management philosophy makes the logistics processes more reliable, flexible, agile and robust while reducing cost. The companies’ risk awareness has increased and their risk management has been improved, thanks to the Six Sigma training programmes and philosophy. Using a combined quality management philosophy, the speed of production could be increased, and the responsiveness and flexibility could be improved, which means quicker response to changes. It has also been indicated that a combined quality management philosophy improves the companies’ resilience, due to their increased agility and strengthened ability to handle variability and risk management. Quality management tools can be very effective in the companies’ efforts to control supply chain risk and to identify risk sources of variation, even outside the focal company. In Six Sigma projects, the root cause of variation is often found outside the focal companies, which requires more collaboration in the supply chain. However, if the companies that use a combined quality management philosophy intend to become more resilient, they must involve suppliers and customers more in their own processes and design products/services and processes together. Collaboration with the suppliers and customers and the notion of how to extend a combined quality management philosophy outside the focal company are of importance in order to make the whole supply chain resilient. This could lead to a problem, especially since the conditions for transport and logistics in regards to the application of quality methods and tools represent a large area, unexploited by the companies. On the other hand, Six Sigma has standardised training courses, and it has been demonstrated how a Six Sigma framework can enable collaboration across companies’ boundaries in the supply chain, with the use of Six Sigma training and the DMAIC-roadmap as a common platform. Even if a combined quality management philosophy is effective and efficient, the companies must re-invest in additional methods, tools and strategies to make the entire supply chain resilient. It could be this re-investment in risk prevention and mitigation solutions that enables faster process responsiveness, the establishment of a risk management culture by creating common values, culture and rules in the supply chain and the use of logistics strategies and methods.

    Preventive maintenance is an enabler for operation excellence in support processes2014Konferensbidrag (Refereegranskat)
    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.

    How to Integrate Suppliers by Training in Lean Thinking2013Konferensbidrag (Refereegranskat)
    Abstract [en]

    Purpose: Much research has addressed how to implement lean in a focal company, but little has been published about how to integrate suppliers in strategies and the focal company’s culture, such as lean production or lean thinking. The purpose of the article is to investigate if suppliers can become more integrated in the supply chain by training in lean thinking at the focal company and to explain a possible structure of the training.

    Design/methodology/approach: A multiple-case study has been conducted of the focal com- pany and five of its supply companies. The findings are supported empirically by on-site interviews and by observations, as well as by a binomial two-proportion test that was used to analyse the statistical data of the delivery precision.

    Findings: While the training programme does not show a conclusive result for the supply chain, it has made a difference for all participating suppliers. In most cases the training programme was a trigger that started or boosted the internal work with continuous improvements. In some cases it helped create structured ways of working and improved the internal production flows.
