    Dynamiska Automationsnivåer2008In: Gjuteriet, ISSN 0017-0682, no 1, p. 24-25Article in journal (Other (popular science, discussion, etc.))
    Abstract [sv]

    Man måste veta varför man automatiserar och hur det kan bidra till konkurrensförmågan. Alltför låg automation ger till exempel låg prestanda och höga kostnader. En för hög automation leder bland annat till höga investeringskostnader och svårhanterliga produktionssystem. Ett lämpligt val av automationsnivå leder däremot till strategiska fördelar och konkurrenskraft.

    Automation Strategies: Implications on strategy process from refinement of manufacturing strategy content2008In: Proceedings of the 19th Annual POM Conference, 2008Conference paper (Other academic)
    Abstract [en]

    Automation decisions are often based on vague ideas that it is always good to automate and thus reducing manpower. These decisions need however to be linked to company manufacturing strategies. If we study the manufacturing strategy field, we can see that these decisions give large consequences in many decision categories. Articles on manufacturing strategy content have been written by e.g. Skinner (1969), Wheelwright & Hayes (1985), Ward et al (1996), Hill (1995), and Swink & Way (1995). Hayes and Wheelwright (1984) developed the content, in terms of decision criteria, as they provided examples of decisions characteristics. This article reviews existing theory on manufacturing strategy content and highlights the implications for manufacturing strategy process when adding more decision characteristics from automation.

    Development Of A Manufacturing Strategy Tool Useful To SME – An Interactive Approach2013In: Proceedings of the 22nd International Conference on Production Research, 2013Conference paper (Refereed)
    Abstract [en]

    This paper report results from a project that deals with manufacturing strategy in small and medium-sized enterprises (SMEs). The project followed an interactive research approach in an iterative manner through four main phases. With these four phases as a foundation, four case studies were carried out. As the project evolved, it became clear that the chosen research approach played a crucial role for the achieved results, which is also what this paper focuses upon. The paper argues that through an interactive research approach, working intensively together with the companies, we have been able to develop an easy-to-use tool that the companies can use and update as needed. The companies have all increased their knowledge on manufacturing strategy as a way of improving competiveness, The research team has increased the knowledge on how manufacturing strategy can be made available and useful for SMEs, and gathered this into an easy-to-use tool, the STRATEGO-tool.

    Automation Strategies: Refinement of Manufacturing Strategy Content2006Conference paper (Other academic)
    Abstract [en]

    Automated manufacturing systems are regarded as highly productive, which improves company’s competitiveness. Many companies consider automation as either fully automated or entirely manual. This is never true since there is always a combination of automated and manual tasks. The delicate issue is to choose the level of automation, LoA, which is best for the purpose. When planning and implementing automated manufacturing systems, a large number of issues need to be considered. Traditional manufacturing strategy theory however treats automation as one subset of process technology decision category. In our research we have come to the conclusion that automation decisions affect much more of the company’s operation activities. Thus, there is a need for developing the manufacturing strategy field in order to embrace relevant aspects/decisions in all of the decision categories. This paper aims at bridging the gap in traditional manufacturing strategy theory and highlights the additional decisions that are necessary in order to cover automation.

    The authors suggest a decision support tool that highlights the different actions that are needed when changing the level of automation in manufacturing systems.

    A tentative comprehensive manufacturing strategy framework adapted to the requirements in SME2012Conference paper (Other academic)
    Abstract [en]

    It is well-known that small and medium sized manufacturing enterprises (SMMEs) lack resources to work actively with their manufacturing strategies. Previous frameworks and tools have shown to work fairly well, but they are too complicated for the SMMEs. This paper presents a suggestion for an easy to use tool.

    Automation strategies: Existing theory or ad hoc solutions?2005In: POM 2005 : 16th Annual Conference Proceedings of POMS: "OM frontiers: winds of change" : Chicago, April 29 - May 2, 2005 : proceedings - full length papers., 2005Conference paper (Other academic)
    Abstract [en]

    Modern manufacturing systems are often semi-automated, i.e. integrating both manual and automated operations. How, and even if, automation should be realized are often ad hoc decisions and not based on structured decision making. This paper examines three approaches to automation decisions: top-down, bottom-up, and contingency. Top management initiates a top-down approach to automation of production. On the contrary, when the decision about automation stems from e.g. the operators, a bottom-up approach is applied. We propose a third way, the contingency approach, which links decisions regarding automation to manufacturing strategies and competitive priorities of the company. Making automation decisions is one of several decision areas that emerge as a consequence of choosing a certain type of production system. The paper discusses important factors for the success of different approaches. Different approaches are illustrated with examples from Swedish manufacturing industry.

    Abstract [en]

    Automating manufacturing systems potentially improves competitiveness. Empirical studies show that the most successful result is achieved when decisions concerning automation are linked to the manufacturing strategies and competitive priorities of the company. It is suggested that automation is regarded as a separate decision group, within the manufacturing strategy content field.

    Automation Strategies: Requirements on the Strategy Process2006In: The morphology of innovative manufacturing systems: 9th CIRP International Seminar on Manufacturing Systems / [ed] P Butala; G Hlebanja, 2006Conference paper (Other academic)
    Abstract [en]

    Automation is a way to improve competitiveness. Previous studies have shown that best results of automa-tion decisions are reached if decisions are integrated in the company’s manufacturing strategy. Automation decisions comprise much more than just the very choice to automate and many aspects need to be taken into account. In this article, we describe new demands that are raised on the strategy process when automa-tion is integrated in the manufacturing strategy. Furthermore, the implementation of automation strategies calls for a number of issues to take into consideration.

    Lagerhantering på Voice AB2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    This examination paper is a lead in the educational program Industrial Management at Jönköping University. The paper itself contains an analysis of the warehouse organisation and its efficiency at the furniture company Voice AB in Torsvik, just south of Jönköping, Sweden. The report also contains propositions to raise the level of efficiency in the company warehouse and warehouse management.

    In the investigation of the warehouse a number of possible improvements were found. Examples are lack of a system for labelling shelves and racks, lack of an efficient location system and development possibilities in work routines. For the empirical investigation both qualitative and quantitative methods ware used. The quantitative methods were used to investigate the physical prerequisites of the warehouse layout, and ratios concerning the handling of components and products. The qualitative methods have been used to get an overview of the handling routines in the warehouse.

    Examples of proposals are among others a system for labelling racks and shelves, new routines in warehouse management and location system. The warehouse slots should be labelled with a system where department, racks, shelves and height can be read from the warehouse slot address. Voice AB should also write a document where it is stated which tasks are associated with specific workers in the warehouse. They should also have a discussion about the strategic parameters in forming an efficient location system for the warehouse.

    Konceptstudie på plug-and-play system2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The report deals with a bachelor’s degree project in Product Development and Design at Jönköping University 2018. The thesis was carried out on behalf of Orkla House Care AB as the concluding part of the Mechanical Engineering program. The work was carried out by Adrian Stanikowski and Carina Wirén.

    The work consisted of developing an extensional concept on a plug-and-play system. Orkla House Care AB bought Anza, a manufacturer of various painting tools, in 2012. Selected products have an extensibility that gives them a more ergonomic approach to painting ceilings, walls, and floors. The existing extension system has an outgoing patent and therefore Orkla House Care has designed this project focusing on product development and construction.

    To get a clearer picture of what users are looking for at the product, a preliminary study was carried out. After the completion of this preliminary study, a product specification could be created. At the idea generation phase, all ideas were recorded where the product specification was omitted to avoid limiting creative thinking. The specification was then the foundation of the final concepts chosen by screening.

    The work focused on creating a user-friendly extension system that clearly shows the function. The focus area has primarily included the elimination of the end plug of the extensible tool, as well as avoiding the use of buttons for attachment and detachment. This focus is to avoid as many misunderstandings for the user as possible.

    The result of the work was a new plug-and-play system with a new design solution.

    Kalkyl för logistikkostnader; från leverantör till förbrukningsplats2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The globalization that has occurred during the last few years has made it more important for companies to have a well-functioning logistics system. Customers demand more options, which lead to an increased flow that creates greater demand regarding packaging and transports. Diverse logistics costs are nowadays a substantial cost for many companies. Therefore, more effort is aimed at optimizing transportation to lower these costs.

    The purpose of this project is to create a user-friendly calculation of logistics costs that illustrates how the costs vary, depending on how the flow is structured. This is done by examining which aspects that affect the total logistics costs and by mapping which aspects that should be included in a calculation of the logistics costs.

    Literature studies have been carried out parallel with empirical studies at Scania's production unit, MC, in Oskarshamn. A calculation of logistics costs is created for them with the purpose of making the materials supply system more efficient. Purchasing agreements are negotiated by Scania’s headquarters in Södertälje, whereas Scania Oskarshamn would like to evaluate the supplier suggestions from a logistics perspective. The company has declared that they are in need of a user-friendly calculation of logistics costs that can be used by many different employees.

    An analysis of the current situation is carried out in order to create a broad foundation of knowledge, regarding what aspects are most important to include in the calculation before creating it. The situation analysis is done through interviews and observations at the company. It shows that there are many different flows, both concerning internal material handling as well as transportation flows from suppliers to Scania Oskarshamn. As a consequence of this, a lot of effort is put into finding ways of simplifying the flows without decreasing the quality of the calculation, meaning its validity.

    The calculation includes five options: weight, volume, packaging, number of boxes on a EUR-pallet, and number of articles in a package. Further, it contains two different parts; one of them is a calculation of transportation costs and the other is a calculation of internal handling. The transportation calculation is founded on data from invoices, gathered and compiled during one year. The calculation of internal handling is founded on handling costs that occur depending on what packages the articles are delivered in, from the supplier. Many of the costs that occur cannot be ascribed to a certain category of packages. Therefore, the allocation of costs is done through allocation keys, according to Activity-Based Costing. The allocations of costs vary in the different areas, because it has not been possible to identify allocation keys to all of them.

    Finally a discussion takes place, concerning the aspects included in the current calculation against those mentioned in the literature. It is also discussed how other companies can make use of the result of this project, to create a calculation of logistics costs for their own business.

    Visual representations for communication in geographically distributed new product development projects2019In: Journal of engineering design (Print), ISSN 0954-4828, E-ISSN 1466-1837, Vol. 30, no 8-9, p. 385-403Article in journal (Refereed)
    Abstract [en]

    This study addresses the role of visual representations in supporting communication between an R&D team and geographically distributed suppliers for a new product development (NPD) project. It specifically focuses on the design and use of visual representations as a feasible way for communication between the distributed actors when they face communication challenges originating from differences in skills in the English language, but also from differences in work experiences. Relying on empirical materials from a Swedish manufacturing company in the mechanical engineering industry, this paper makes the following contributions to the literature. First, it shows that visual representations are effective boundary objects able to support process-oriented and product-oriented communication in distributed NPD projects. Second, it illustrates that visual representations do not necessarily have to follow graphic design principles, but can still be effective if distributed actors share the same project context. Finally, it highlights the need for a dynamic and context-dependent perspective on communication in NPD projects.

    Transdisciplinary Engineering Research Challenges2018In: Transdisciplinary Engineering Methods for Social Innovation of Industry 4.0: Proceedings of the 25th ISPE Inc. International Conference on Transdisciplinary Engineering / [ed] Margherita Peruzzini, Marcello Pellicciari, Cees Bil, Josip Stjepandić, Nel Wognum, IOS Press, 2018, p. 753-762Conference paper (Refereed)
    Abstract [en]

    Transdisciplinary research (TDR) has been the subject of discourse in the past few decades, but has not been studied much in the context of engineering problems. Many engineering problems can be characterized as ill-defined, like open innovation, adoption of new technology, business development, and the adoption of the Industry 4.0 concept. Transdisciplinary engineering research (TDER) is also performed in large projects by multi-disciplinary teams, as in TDR projects, including stakeholders and people from practice. Such projects may last long, often years. In such large projects, the involved disciplines should include both engineering disciplines as well as disciplines from social sciences. In this paper we address the challenges that exist in adopting a TDER approach. Universities need to prepare students to work in TDER projects. We discuss the current situation in transdisciplinary engineering education (TDEE) and identify challenges that need to be addressed for including TDEE in curricula. The paper ends with a summary and ideas for further research.

    Transdisciplinary systems engineering: Implications, challenges and research agenda2019In: International Journal of Agile Systems and Management, ISSN 1741-9174, Vol. 12, no 1, p. 58-89Article in journal (Refereed)
    Abstract [en]

    Transdisciplinary processes have been the subject of research since several decades already. Transdisciplinary processes are aimed at solving ill-defined and socially relevant problems. Many researchers have studied transdisciplinary processes and have tried to understand the essentials of transdisciplinarity. Many engineering problems can be characterised as ill-defined and socially relevant, too. Although transdisciplinary engineering cannot widely be found in the literature yet, a transdisciplinary approach is deemed relevant for many engineering problems. With this paper we aim to present an overview of the literature on research into transdisciplinary processes and investigate the relevance of a transdisciplinary approach in engineering domains. After a brief description of past research on transdisciplinarity, implications for engineering research, engineering practice, and engineering education are identified. In all three areas, the current situation is described, while challenges are identified that still exist. The paper ends with a research agenda for transdisciplinary engineering.

    Abstract [en]

    Abstract 

    A capacity study has been made on a production line for a leading bearing and seal manufacturing company – In a view of manufacturing technology, logistics and economic. 

    Simon Wolf is the author of this thesis and his mentor is named Jonas Bjarnehäll. 

    On the two types of actuators, line balancing should be made in order to decide the maximum capacity with a different amount of staff used. An investment analysis will be needed to investigate if an investment can be presumed to be appealing from a financial perspective. Finally, the location of the stations should be made which will be adapted to the investment and line balancing

    The purpose of this thesis is to develop the most effective layout possible regarding both operator- and production effectiveness.

    The thesis is made using the methods following: 

    • The six steps for line balancing

    • Systematic Local Planning

    • Carrying cost calculation

    In conclusion, 46 functional classifications and a placement arrangement that fits to those and other criterias has been produced. Following an investment analysis between two different layouts one can find the most successful and effective one. All these constitute the result of the thesis.

    Analysis of form postponement based on optimal positioning of the differentiation point and stocking decisions2009In: International Journal of Production Research, ISSN 0020-7543, E-ISSN 1366-588X, Vol. 47, no 5, p. 1201-1224Article in journal (Refereed)
    Abstract [en]

    In this paper we analyse the use of form postponement based on the positioning of the differentiation point and stocking policy. Six classes of manufacturing configurations are identified based on the choice of whether or not form postponement is employed and the decision regarding the stocking policy for the final product configurations as well as for the generic component. Analytical evaluation methods based on queuing models are used to assess operational measures for each class of configuration and solution algorithms are developed todetermine the optimal positioning of the differentiation point and the optimalstocking levels. This allows us to compare the relative merits of all manufacturingconfigurations based on their respective best performances. The results of anumerical experiment show how different operational parameters may influencethe choice of optimal configuration, the preference of early or late postponement,and the relative cost savings obtained from employing form postponement.

    Investment Performance of the World Automotive Industry2006Independent thesis Advanced level (degree of Magister), 10 points / 15 hpStudent thesis
    Abstract [en]

    The paper examines the investment performance of the world automotive industry using a sample of 21 original equipment manufacturers (OEMs) based in three major continents, North America, Europe and Asia between the years 1999 and 2004. The empirical findings suggest that there exists persistent overinvestment not only in the global level but also in the major automotive production regions analyzed. Proving that none of the 3 regions gain returns on investment at least as large as their costs of capital, shareholder wealth is not maximized in the world automotive industry. Europe, among these regions, proves to gain the highest return on investment of its cost of capital. The empirical results also show that the return on investment financed by debt is high around the world and close to 100% of its cost of capital.

    Improvement of Work Process in a Global Verification Team: A case study at VSM2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    With increasing demands from customers, companies face the challenges of shortening the new product development (NPD) period, reducing development cost and increasing development efficiency. High quality and efficiency of NPD can increase the chance for companies to be competitive on the market. Forming up cross-functional teams becomes a popular way of maximizing the knowledge then increase the development quality and efficiency. However, it is challenging to integrate the resources from different functions and even more challenging when the resources are from different countries. To overcome the integration challenges can increase the efficiency of NPD projects therefore finally win global market shares. This study’s purpose is to identify and analyze integration challenges experienced by a verification team involved in global NPD and to suggest how those challenges can be managed by answering two research questions: 1) What are the integration challenges with the current work process encountered by the global verification team? 2) How can the integration challenges be met in the improved work process? The case study is used as the research method in order to get deep insight of the challenges that a global verification team faces. VSM Group AB, an international leading sewing company is selected as the case company.  The case team, a global verification team locates both in Sweden and China, plays the role of verification work within NPD process. The case team verifies the design and new products in the process.  Through interviews, observation and literature reviews, the challenges in this global verification team are identified. It is found that the case team needs to overcome language barriers, culture difference, task planning and formalization and standardization on work performance during integration. Based on the investigations, a set of solutions are proposed in the end to meet the challenges. These solutions are an improved work process, work performance system, training program and uniformed documentation. These proposals are inspired by the integration mechanisms such as formalization and standardization, special reports etc and then fit them into the case team context. By simulation and evaluation the solutions within the global verification team, the feedback on the proposals helped for improvement. This case study at VSM is an empirical example of implementation of integration mechanisms into a real life context.

    Framgångsfaktorer vid övergång till ISO 9001:20152017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose with this study aims to identify the most important and critical factors for small-sized companies to make way for a successful transition to ISO 9001:2015. Because of the new structure, it is difficult for companies to interpret the standard and what is required to achieve a certification. This study has therefore been carried out at the manufacturing company FIG Metall in Gnosjö. 

    The study is based on qualitative research. Observation, interviews and document views were made at FIG Metall. Interviews were also carried out with the auditing company Qvalify and the Swedish Standards Institute to receive their views on which the important factors are as well as the general difficulties for companies when transitioning.  The interviews were semi-structured which resulted in an open discussion where the respondents were free to answer based on how they perceived the questions.

    The results of the empirical data were the basis of the analysis and the conclusion. The different methods used in the report can be seen in figure 10 which shows the triangular approach of the study. Qvalify and SIS agreed upon the same areas companies need to focus on when transitioning to ISO 9001:2015.

    The result of this study shows that the most important areas smaller companies need to focus on when transitioning are Leadership, Context of the organization, Risk based thinking and Process approach. The study concluded that ISO 9001:2015 is closely related to total quality management (TQM), organizational development and organizational psychology and can be used as complementary tools to the standard.

    Sustainability performance indicators at shop floor level in large manufacturing companies2017In: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 61, p. 457-462Article in journal (Refereed)
    Abstract [en]

    This article investigates sustainability in the performance measurement systems of Swedish manufacturing companies. It builds on a previous study that documents relatively few direct environmental indicators at shop floor level, which raises questions about possible indirect links between existing indicators and the environment that could be used to improve the environmental aspect of company´s sustainability ambitions. 

    A method for identifying and categorizing indirect links to sustainability issues was defined and used. The results suggest that at shop floor level 90% of the indicators have at least an indirect relation to one or more of the sustainability dimensions economy, environment and social, of which 26% are at least indirectly related to the environmental dimension. Despite the many indirect connections, participating companies perceive a need to improve sustainability indicators and some ideas are suggested.

    Automation from lean perspective: Potentials and challenges2013In: Proceedings of the 11th International Conference on Manufacturing Research (ICMR2013), Cranfield University, UK, 19th – 20th September 2013, International Conference on Manufacturing Research (ICMR) , 2013, p. 437-442Conference paper (Refereed)
    Abstract [en]

    The competitive climate of production and high labour cost, motivate western companies to use technologies like automation as a mean to increase manufacturing competitiveness. On the other hand companies are aware about cost reductive policies like lean production which has shown noticeable achievement, consequently some manufacturers tend to follow such system. In this situation, in order to have lean enterprise, it is vital to find a clear picture of challenges and potentials of implementing automation within a lean environment. So, finding the right level and type of automation becomes vital for companies, and achieving this is not possible without a lean development of automation. The paper presents an overview of automation development from a lean perspective. The focus is on manufacturing and a case study in the automotive industry is presented. Challenges and potentials of automation are pinpointed and some suggestions regarding automation development is given.

    Värmebehandling av segjärn med hög kiselhalt2011Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The background to this thesis was that Qumex Materialteknik at several occasions had received material of type SS 0725 that had shown deficient heat treatment results. The material, which is relatively new, is a cast iron of type ductile iron and differ against other ductile irons because of its high silicon content. According to EN standard ductile irons are classified by their mechanical properties. A problem then occurs with the new material SS 0725 because of this. The material fulfils the requirements for EN-GJS-500-7 and is therefore in the same classification as a ductile iron with much lower silicon content. Two materials having major differences in chemical composition ending up in the same classification can be problematic. The purpose of this report is to determine impact of high silicon content in ductile iron when heat treated and quench hardened.

    The experiment included four materials, and the major difference between the materials were their content of copper and silicon. The heat treatment process was performed at three different temperatures and three different treatment times. Afterwards the samples were quenched in oil. The ambition of the quench hardening was to obtain a material structure of 100% martensite. By optical microscopy and hardness measurements the results then were evaluated. An investigation of the phase transformation temperature in the materials was made by using Differential Scanning Calorimetry.

    The results show that the amount of silicon content has great influence on the temperature for receiving good hardening results. To achieve 100% martensite after quench hardening in materials with low silicon content the temperature needs to be over 840°C. For material with high level of silicon content the temperature for achieving 100% martensite needs to be 900°C and the treatment time should be over 1 h. The relative difference in phase transformation temperature was measured using Differential Scanning Calorimetry. The results of the measurements between the materials with high silicon content and materials with low silicon content was 45°C. This result combined with the analysis of the heat treatment process shows that a major increase of the temperature is needed to heat treat SS 0725.

    Effektivisering och produktivitetsökning i produktionsflödet av Hammarhäftare på Isaberg Rapid AB2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    The market’s demand to purchase more cost effective products is continuously increasing. The producers are forced to become more efficient and flexible with resources to produce high quality products at a low cost in order to maintain or increase market shares. With this in mind Isaberg Rapid AB is requesting a project to increase efficiency in the assembly cell of hammertackers. The company has found in Kaizen-events that there is a potential of efficiency improvements in the assembly group that has not been achieved.

    The objective with this paper is to identify the major factors that influence the efficiency in the assembly cell for hammertackers. At the same time the project is to generate data on new operation times, calculate the number of operators required in the cell and to implement standardized work instructions.

    The facts and data have been collected by discussions with operators, time studies and by filming the operation. A one week Kaizen-event with the operators was made, where the selected changes were implemented. The result of the changes in terms of efficiency and output were registered.

    The following basic questions are answered in the report.

    • What changes are required to increase efficiency?
    • What are the non-conformity reasons that prevent the group from reaching the production targets?
    • Is there a need for a different set up in the cell?

    In the Kaizen-event, a number of observations were made in the hammertacker group and the major wastes were identified. The largest wastes were identified to be that materials for packing were too far from the assembly cell, setting times for tool changes were long and that the operators’ workload was not in balance.

     A new layout was made to reduce the distance to packing materials. The height and setting of moulds were changed to get faster mould exchange. Operations were  introduced to the cell to get a better balance of the workload between operators.

    The observed interruptions have mainly been due to lack of different raw materials.

    There was no reason to modify the way work was carried out in the cell; never the less, some minor adjustments were made. The change with the biggest impact was to remind the operators of the factors that affect the productivity most.

    The number of produced products has increased by 21 %, which also gives the corresponding efficiency increase.

    The conclusion of this paper is that increased productivity is obtained by identifying and eliminating waste, increasing the participation of the operators and creating a standardized way of working.

    Designing proactive assembly systems: Criteria and interaction between automation, information, and competence2009In: Proceedings of the 42nd CIRP Conference on Manufacturing Systems, Grenoble, 2009Conference paper (Refereed)
    Abstract [en]

    Increasing customisation of products results in decreasing production batch sizes, especially in the final assembly. Industry must therefore increase their capability to handle smaller batches as well as radically decrease set up time between different product groups and new products. This paper suggests the need for further development, primarily addressing time parameters in dynamically changing assembly systems. We propose customer demands and decrease non value-adding tasks. In proactive assembly systems, the full and complementary potential of human operators and technical systems is utilised. Criteria for proactivity in assembly systems are reviewed from automation, information, and competence perspectives.

    Optimization Driven Development of Stringer to Leisure Boat2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The increasing demand for products of light weight and high performance to be produced and developed in shorter periods of times has put high pressure on the product development process. Much research is done in order to find ways on how to speed up this process at the same time as delivering products of higher quality to the customer. Much of the literature focuses on how important it is to “tear down the walls” between departments at a company by integrating as much different knowledge as early in the process as possible. Thereby, much of the costly problems found late in the process can be avoided leading to shorter development times and cost savings.

    Commonly companies use simulation software to verify their final designs before the products pass forward to prototyping and test production. In some cases products need to be redesigned and big changes of the product geometry might be necessary which often is very costly in such a late stage of the process.

    Eker Design in Fredrikstad, Norway, wants to investigate the potential of using simulation driven design in an early stage of the product development process. In order to make this investigation this exam work has been carried out on a real design case by the development of a new “stringer” totally from scratch. A stringer is what gives rise to the stiffness of the boat and is a structure mounted in-between the hull and the deck. The stringer was developed to the Hydrolift SX22 leisure boat by using simulations and topology optimization software as the driving force for the design. The research questions to be answered were:

    • Is it possible to develop a stringer through a design process based on topology optimization and simulation software with equal performance as the existing stringer?
    • How does the optimized result perform in comparison to the existing stringer?
    • Can any weight reduction be achieved with a new stringer design?

    In the end of the work the existing stringer and the new stringer design was compared and evaluated. The results showed that the new stringer with a weight reduction of 30% performed very well in comparison to the existing one. This proves that the topology optimization and simulation driven design process beneficially can be used in marine architecture. It has also proven to be an efficient method to lower the material usage and increase the strength of the stringer.
