    Kartläggning av ergonomin i en produktionscell: Med utformningsförslag för en ergonomisk arbetsplats2016Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    ABSTRACT

    Purpose: The aim of the work is to map the ergonomics in a production cell and propose and compare the solutions to identified problems. In order to identify the problem and come up with some solutions, these questions have been answered.• What factors lead to operations that are harmful to the body?• How can a production cell be designed to be more ergonomic for employees?• What are the advantages / disadvantages of ergonomics in a production company?

     

    Method: To perform the study and achieve the purpose of the work, the authors used a case study company where observations were made in parallel with a literature review mainly on ergonomics variety of analysis and quality. The case study company has been used as the basis for the case study where ergonomics are mapped by means of observations, interviews and data that were analyzed by means of literature study done in parallel.

    Study results: The study resulted in a survey of ergonomics in a production cell at the case study company and 5 different suggestions for improvement. The production cell on the case study company is a red cell today, which means that the production cell is in a non-accepted position and in need for urgent changes in ergonomics. Factors leading to bad ergonomics and a non-accepted position as Volvo's requirements have been identified. Many heavy lifting and many torque is what has the highest negative impact on the working environment and ergonomics. Lack of adequate lifting tools have led to those not used in the production cell today. This leads to repetitive work and encumbrance at the case study company. Further, also the working height of the paths contributed to an increased workload as operators are in an unnatural posture. All of these factors are the basis of the 5 suggestions for improvement as the study also resulted in. New custom lifting tools, job rotation, reverse the order of the court, new packaging and pallet to the gears and the robot turn. All these proposed solutions lead to reduced stress and improved ergonomics in the production cell as manual lifting and twists are reduced. The solutions also leads to the production cell shifting from a non-accepted position with demands of urgent change to a yellow production cell that requires an action plan for the future.

     

    Implications: The aim of this study was to map the ergonomics in a production cell. With the study in hand, a conclusion is drawn that the aim has been achieved when all three of the questions have been addressed. Factors leading to poor ergonomics are identified. As well the advantages and disadvantages of investing in ergonomics identified and how production cells should be formed. With this information in mind, a number of proposed solutions have been developed.

     

    Recommendations: Further studies on the subject are recommended to increase knowledge and interest. It may be appropriate to carry out more case studies at more industries to strengthen the study’s results and generalizability. Furthermore, studies are recommended where the entire work environment is studied and not only physical ergonomics. By studying the whole working environment and the many factors that interact it can lead to a greater force being created for higher efficiency and quality in production.

    Exploring value proposition of service offerings in telematics system2018Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Services are making a huge impact in the business sector especially in the developed countries. As services are customer-centric, there is a need for an enhanced process framework connected to integrated service development. Such a framework should ideally address value propositions meeting specific customer needs in identifying corresponding service offerings. In this context, this thesis aims to explore on how value propositions are defined, developed, and communicated during the introduction of service offerings and to identify the ways to improve the process of value propositions. The work is carried out in the context of a major (Swedish) manufacturing company within a specific product context, namely, the telematics system. The main data collection methods are personal observations, semi-structured interviews, meetings, and company documents. The study seeks to answer three questions: First, what are the value propositions addressed by the current service offerings in telematics system in the context of heavy-duty vehicle equipment? Second, how value propositions are created during the development of these services offerings? Third, how can the service offerings for telematics system be improved through the process of value proposition? The study found that two types of value propositions namely customer value proposition and stakeholder value proposition are addressed by the service offerings in telematics system. Additionally, it is found that value propositions are created in relation to service offerings. Finally, the thesis proposes a six-step conceptual framework to create better value propositions during the development of service offerings. The presented framework is applied to the current value proposition process at the case company and improvement suggestions are proposed, which can impact the service offerings in the near future. The thesis has contributions to enhance or create new service offerings through addressing the value propositions and applying them. The results are beneficial for managers and developers who work in developing the future state scenarios or business models.

    The fuzzy front end of manufacturing technology development: Exploring the link between the known and the unknown2017Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    It is well known that a way of competing on a global market is through the introduction of new manufacturing technologies in the production system that can improve product quality as well as contribute to reducing manufacturing time, reduced product price and in the end increased profits. Manufacturing companies that develop and introduce new manufacturing technologies can differentiate themselves from others and thus achieve increased competitiveness.

    The fuzzy front end of manufacturing technology development is characterized by a high degree of technology uncertainty and challenges due to the lack of access to relevant knowledge, lack of a structured development process, and enough resources that are working with development of new manufacturing technologies.

    In the literature only a few empirical studies that explore the fuzzy front end of manufacturing technology development can be found. Prior research highlights that little is actually known about what should be done in the fuzzy front end of manufacturing technology development projects, and thus more research is needed. Supporting the fuzzy front end of manufacturing technology development is important to facilitate a successful introduction of new manufacturing technologies, fast time-to-volume and long-term production system development.

    Based on the above-mentioned importance of developing new manufacturing technology, the objective of the research presented in this thesis is to explore the fuzzy front end of manufacturing technology development. In order to fulfil the objective, empirical data were collected from five case studies conducted in the manufacturing industry. During the empirical studies four important parts were studied: organising, knowledge development, collaboration and the development process.

    The main findings revealed that development of new manufacturing technology is often conducted in collaboration with external partners and many ad hoc decisions are taken due to lack of a predefined development process for the fuzzy front end of manufacturing technology development. In addition, in the fuzzy front end access to relevant manufacturing knowledge is important and knowledge needs to be developed in order to reduce technology uncertainty.

    In order to support the fuzzy front end of manufacturing technology development projects, a supporting framework has been developed. The proposed framework is an elaboration of results from the research questions addressed and can be used as a guideline to overcome the challenges observed in the fuzzy front end of manufacturing technology development projects. The framework is built on two important dimensions for innovations, degree of technology uncertainty and degree of novelty. The critical factors identified in the analysis are embedded in the proposed framework as central parts in the fuzzy front end of manufacturing technology development.

    Knowledge integration in manufacturing technology development2017Ingår i: Journal of Manufacturing Technology Management, ISSN 1741-038X, E-ISSN 1758-7786, Vol. 28, nr 8, s. 1035-1054Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose - The purpose of this paper is to identify and analyze knowledge integration in manufacturing technology development projects required to build competitive advantages. Design/methodology/approach - A longitudinal case study has been conducted at a Swedish manufacturing company by following a manufacturing technology development project in real time during a two-year period. Findings - The results show that three different knowledge integration processes exist when developing unique manufacturing technology: processes for capturing, for joint learning, and for absorb learning. The findings of the current research suggest that the three knowledge integration processes are highly interrelated with each knowledge integration process affecting the other two. Research limitations/implications - The major limitation of the research is primarily associated with the single case, which limits generalizability outside the context that was studied. Practical implications - The findings are particularly relevant to manufacturing engineers working with the development of new manufacturing technologies. By using relevant knowledge integration processes and capabilities required to integrate the knowledge in manufacturing technology development projects, companies can improve design and organize the development of manufacturing technology. Originality/value - Previous research has merely noted that knowledge integration is required in the development of unique manufacturing technology, but without explaining how and in what way. This paper's contribution is the identification and analysis of three knowledge integration processes that contribute to the building of competitive advantages by developing unique manufacturing technology and new knowledge.

    The application of system dynamics and discrete event simulation in supply chain management of Swedish manufacturing industries2012Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Increasing competition from traditional and emerging channels has placed new emphasis on rapid innovation and continuous differentiation in every aspect of supply chain, from earliest production stage to the final distribution steps. To bridge the gap between brilliant ideas and successful business initiatives, leading companies implement engineering simulation particularly in logistics and supply chain management (LSCM). Discrete event simulation (DES) and system dynamics (SD) are two modeling approaches widely used in this field. However there are not much done researches about the applications of these simulation approaches in supply chain context of Swedish Manufacturing Industries (SMI). This study explores the application of DES and SD in LSCM of SMI by looking at the nature and level of issues modeled. Journal papers and master theses that use these modeling approaches to study supply chains, published between 1990 and 2012 are reviewed. A total of 39 articles are analyzed to identify the frequency with which the two simulation approaches are used as modeling tools in LSCM of SMI. Our findings suggest that DES has been used more frequently to model supply chains in SMI. The results also show that not all the LSCM issues have been addressed evenly and generally tactical/operational issues have been modeled more frequently. The results of this study inform the existing literature about the use of DES and SD in LSCM of SMI.

    Ranking of Two Multi Criteria Decision Making Cases with Evidential Reasoning under Uncertainty2017Ingår i: Advances in Science, Technology and Engineering Systems Journal V2(3) ASTESJ-V2(3), ISSN 2415-6698, Vol. 2, nr 3, s. 1059-1063Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Many decision problems have more than one objective that need to be dealt with simultaneously. Moreover, because of the qualitative nature of the most of real world problem it is an inevitable activity and very important to interpret and present the uncertain information for making effective decision. The Evidential Reasoning (ER) approach which is one of the latest development within multi criteria decision making (MCDM) seems to be the best fit to synthesize both qualitative and quantitative data under uncertainty. To support this claim, two case studies were tested to illustrate the application of ER for prioritization and ranking of decision alternative to support decision process even with uncertain information. The overall goal of the first case study is to identify and prioritize factors that can be considered maintenance-related waste within the automotive manufacturing industry. The result after applying ER shows “inadequate resources” and “weather /indoor climate,” respectively, are the highest and lowest average scores for creating maintenance-related waste. This prioritization methodology can be used as a tool to create awareness for managers seeking to reduce or eliminate maintenance-related waste. The aim of the second case study is to look at the possibility of having a new approach for sustainable design. So through a literature review six design strategies were taken into consideration in order to develop a new approach based on all advantages (sustainable factors) of the six approaches. For ranking and finding out about the most important factors the evidential reasoning (ER) approach is used. Based on ER all the important factors, apart from the one collected from interviews are a part of eco-design. So it means among all strategies eco-design is the most dominant strategy in term of environment. However two of the important factors are not found in any strategy but in interviews. These factors can be used as the building blocks for a new approach. The importance of having a better structured decision process is essential for the success of any organization, so it can be applied widely in most of real world problem dealing with making effective decision.

    Classification of Maintenance-Related Waste Based on Human Factors2015Ingår i: 22nd International Annual EurOMA Conference EurOMA15, Neuchâtel, Switzerland, 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    The goal of this research is to identify and classify factors creating maintenance-related waste. A workshop study has been performed in order to identify root-causes for maintenance-related waste. In total, 16 categories were found in the analysis and it is concluded that these are heavily reliant on human factors as a root- or major contributory cause. These, together with factors based on a literature review have been incorporated into a classification model. The model can be used in creating awareness in, as well as provide a basic framework for decision making of, which waste to target for elimination.

    Using evidential reasoning approach for prioritization of maintenance-related waste caused by human factors-a case study2017Ingår i: The International Journal of Advanced Manufacturing Technology, ISSN 0268-3768, E-ISSN 1433-3015, Vol. 90, nr 9-12, s. 2761-2775Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The reduction and elimination of maintenance-related waste is receiving increasing attention because of the negative effect of such waste on production costs. The overall goal of this research is to identify and prioritize factors that can be considered maintenance-related waste within the automotive manufacturing industry. Five manufacturing companies participated in a workshop to identify root causes of maintenance-related waste; 16 categories were found. The identified factors were heavily reliant on human factors as a root or major contributory cause at different levels affecting performance and productivity. For prioritization, the evidential reasoning (ER) approach which is one of the latest developments in multi-criteria decision-making is applied. A basic tree structure necessary for ER assessment is developed based on the workshop results as well as literature on human factors. Then, a survey on basic attributes at the lowest level of this tree is designed and performed at one of the companies participating in the workshop. The application of ER shows that, on an overall level, "management condition" is in first order and "maintainer condition" and "working condition" are in second and third order respectively as the worst cases for creating maintenance-related waste. On the most delimited level "inadequate resources" and "weather/indoor climate" have the highest and lowest average scores respectively in ER ranking or prioritization. This methodology with its resulting ranking can be used as a tool to create awareness for managers seeking to reduce or eliminate maintenance-related waste.

    AN INVESTIGATION OF THE MOST IMPORTANT FACTORS FOR SUSTAINABLE PRODUCT DEVELOPMENT USING EVIDENTIAL REASONING2017Ingår i: Numerical Algebra, Control and Optimization, ISSN 2155-3289, E-ISSN 2155-3297, Vol. 7, nr 4, s. 435-455Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Those working in product development need to consider sustain ability, being careful not to compromise the future generations ability to satisfy its needs. Several strategies guide companies towards sustainability. This paper studies six of these strategies: eco-design, green design, cradle-to-cradle, design for environment, zero waste, and life cycle approaches. Based on a literature review and semi-structured interviews, it identifies 22 factors of sustainability from the perspective of manufacturers. The purpose is to determine which are the most important and to use them as a foundation for a new design strategy. A survey based on the 22 factors was given to people working with product development; they graded each factor by importance. The resulting qualitative data were analyzed using evidential reasoning. The analysis found the factors minimize use of toxic substances, increase competitiveness, economic benefits, reduce material usage, material selection, reduce emissions, and increase product functionality are more important and should serve as the foundation for a new approach to sustainable product development.

    Sustainable production adoption by Surface Treatment SMES: challenges and enablers2015Ingår i: Global Cleaner Production & Sustainable Consumption Conference 2015 GCPC2015, 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

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

    Examensarbete: Implementering av2007Självständigt arbete på avancerad nivå (magisterexamen), 20 poäng / 30 hpStudentuppsats
    Abstract [sv]

    I denna rapport behandlas verktyget FMEA (Failure Mode Effect Analysis), dess användning och genomförande på identifierade komponenter som ingår i elmotorer tillverkade hos ABB LV Motors i Västerås. Målet med detta arbete har varit att ge lärdom om metoden FMEA på företaget för att möjliggöra användandet av verktyget bland medlemmarna på företaget och att vi implementerar verktyget på befintlig motor för att analysera de felsätt som kan uppstå. Eftersom ABB just nu har ett pågående projekt med en ny motor kan våra slutgiltiga felanalyser även ge dem information om vilka ändringar och åtgärder som kan vara till nytta vid utformningen av den nya motorn.

    Efter två veckors praktik i verkstan och en grundlig genomgång av företagets reklamationer kunde vi avgränsa arbetet genom att identifiera de komponenter som analyserna skulle genomföras på. Efter en genomgång tillsammans med våra handledare på företaget kom vi fram till att utföra våra analyser på fem komponenter, två av dem framstod som mycket kritiska som upptäcktes redan vid genomgång av reklamationerna.

    Komponenterna som vi har analyserat är:

    1. Lager

    2. Lindning

    3. Tätning av uttagslåda och uttagslock

    4. Fötter

    5. Sköldar

    Lager som är den näst största kritiska komponent som vi tittat på är en del i motorn som är väldigt känslig, det är viktigt att följa instruktioner för underhåll och smörjning för att undvika för tidiga lagerskador.

    Lindningen är klart den mest kritiska komponenten i våra analyser, detta är för att det är så mycket som spelar in lindningens funktion, koppartrådar, isoleringar, impregnering samt under själva processen kan det uppstå felsätt som påverkar lindningen negativt både direkt men även i ett senare skede då motorn är i drift.

    Tätning av uttagslåda och lock beskriver de felsätt som kan uppstå då tätningen inte är effektiv och tät, vad som kan hända då det kommer in smuts och fukt och hur det eventuellt kan påverka plint eller andra elektriska applikationer. Felanalysen på fötter och sköldar behandlar mycket designfel, toleransfel och hur det påverkar komponenterna.

    I rapporten beskrivs utförligt komponenternas funktioner, processer, underhåll samt det är i princip vad vi har kommit fram till i våra felanalyser fast vi i rapporten beskriver det mer utförligt. Efter beskrivning av varje komponent följer ett FMEA för respektive komponent och de FMEA:n är våra resultat av arbetet, där visas åtskilliga felsätt som är möjliga att uppstå hos varje komponent och även vilka felsätt som är mest kritiska att ta itu med.

    Kåpning till brandspaningsrobot FUMO 32013Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Detta projekt har utförts på en 10 veckors period och ligger på C-nivå (15högskolepoäng). Projektet gick ut på att ta fram ett kåpningsförslag för FUMO 3. Under denna period har de första 6 veckorna bestått av konceptframtagning och bearbetning av koncept, och de sista 4 av själva prototypframtagningen. Metoderna som använts för idégenerering och konceptframtagning har varit diverse produktutvecklingsverktyg. Då många ändringar och korrigeringar gjordes framför allt gällande basplatta, IP-lådor och externa enheter ganska sent in i projektet kunde gruppen inte fastställa ett konceptförslag förrän närmare slutet av arbetet med detta projekt. Prototypframtagningsprocessen utfördes genom bockning med maskin och för hands samt hopsättning genom popnitning. Mallar för utklippta plåtbitar togs fram genom CAD-ritningar som sedan ritadesut på pappskivor, som sedan provades på roboten i förväg. Då arbetet med prototypframtagningen gjordes i största mån för hand så lämnade gruppen utrymme för felpassningar som kunde uppstå på grund av felklippta plåtar, felaktiga bockningskanter och radier, skissnoggrannhet och annat orsakat av den mänskliga faktorn. Som slutsats ser vi oss ändå nöjda med att ha uppflyllt kraven under den tid som var utsatt.

    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.

    Reconfigurable Manufacturing - An Enabler for a Production System Portfolio Approach2016Ingår i: Procedia CIRP, 2016, Vol. 52, 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.

    Abstract [sv]

    E-verkstaden på GETRAG All Wheel Drive i Köping har effektivitetsproblem i delar av sin utrustning. Störst problem har avdelningen med fyra automatiserade fleroperationsceller som bearbetar ämnen till slutväxelhus. Till största del är det den stora mängden småstopp som ligger till grund för den låga effektiviteten.

    Avdelningen arbetade redan vid starten av detta examensarbete i viss mån med störningsloggning och effektivitetsberäkningar. Dock utfördes inte detta arbete i den utsträckning och med det djup som krävs för en systematisk uppföljning av störningar.

    Syftet med detta arbete var att visa på ett effektivare och mer systematiskt sätt att arbeta med störningsloggning och uppföljningsarbete. Dessutom granskades utrustningen med en effektivitetsmätningsmetod som om den används rätt är en mer kraftfull och visuellt bättre metod än den som används av företaget idag.

    Då en inledande nulägesanalys utfördes på den berörda produktionsutrustningen upptäcktes brister i avdelningens dokumenterade kunskaper kring utrustningen. Dessutom visade sig effektiviteten vara betydligt lägre än de tidigare redovisade resultaten.

    Med hjälp av nya metoder för störningsloggning och en mer ingående uppföljning av felorsakerna studerades den valda utrustningen i tio veckor. Studierna påvisade att det finns stora möjligheter till effektivare och mer vinstgivande produktion genom att systematiskt arbeta bort de kroniska störningar som finns i produktionsutrustningen.

    Utifrån studierna som utförts och de teoretiska referenserna presenteras ett arbetssätt baserat på allas delaktighet, som kan användas av E-verkstaden för att på ett systematiskt sätt arbeta med ständiga förbättringar i produktionen.

    Abstract [en]

    This chapter proposes a way of understanding and cultivating places for radical innovation in operations. This chapter describes how, organisations can, instead of letting an innovation laboratory be its single economic and managerial priority, foster a decentralised, varied and emergent palette of places in use where radical innovation can occur. The chapter suggests that this can be done in lean production facilities and radical innovation be balanced with incremental innovation.

    Communication space: Spatial design in manufacturing industry2011Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    The main concern of this licentiate thesis is to discuss how built space is used for communication in the manufacturing industry, from a visual communication perspective. The thesis presents and develops the notion of 'communication space' and presents a model to describe the relation between different factors in the communication space.

    In a multiple case study, six different cases from the manufacturing industry are described and analyzed to highlight how built space is used for communication in a lean production context. Research results on how built spaces such as improvement places, meeting places and a development workshop affect improvement processes and communication are presented. What the studied improvement areas, meeting places and workshop can be said to communicate about the improvement processes is analyzed.

    The research results show that the built spaces in manufacturing industry are used for communication on two levels, both as places for interaction between employees and as a part of a communication process. The study also shows a relation between architecture from a specific time and the relation to the improvement work in the industrial context. How the results can be used to facilitate communication in the built spaces used for improvement processes in manufacturing industry is suggested in the thesis.

    Abstract [en]

    The paper present research results on how a spatial design can communicate and support

    production performance in relation to lean production. The main concern of this paper is to

    discuss the role of interior design and its affect on humans in a production system and to

    contribute to a more profound understanding of lean production from a communicative aspect.

    This paper is focusing on three case studies: a project studio, a prototype workshop, and a

    development workshop in manufacturing companies. The study in the development workshop

    is conducted during a period of two years, with an ambitious survey as follow up. The

    two others are context cases to exemplify and investigate the role of interior design in an

    industrial environment, with project studios as the main subject.

    The research method chosen is case study methodology including a literature review related

    to examples from the industrial case studies.

    In industry, spatial design in interaction with visual artefacts can be used to reduce the 8th

    waste by supporting effective communication, cross-functional work, decision-making processes,

    reinforcing the project identity, facilitating project management, save time, shorten

    led time for development projects and inspire employees to a positive view of the company

    and the project.

    A holistic approach to acquisition of strategic resources2007Ingår i: Journal of European Industrial Training, ISSN 0309-0590, Vol. 31, nr 8, s. 660-677Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose - The aim of this article is to provide a holistic framework for the acquisition of strategic resources. Design/methodology/approach - The literature dealing with resource creation is reviewed and analyzed from a resource-based point of view. The major methods of acquiring resourcesare identified through the literature review and the applicability of the framework proposed is illustrated with an empirical example. Findings - Three ways of acquiring strategic resources are identified - direct investments, organizational processes, and product market positioning. All three ways of acquisition can be intentional or unintentional. Arguments for using this six-dimension scale are provided through deductive reasoning, literature review, and the empirical example. Research implications/limitations - The study identifies the six dimensions of strategic resource acquisition. However, integration of these dimensions is not a subject addressed in this study. Cluster analysis of companies according to these dimensions could enhance our understanding of the characteristics of companies regarding resource acquisition. Originality/value - Whereas previous studies have generally used a single-theory approach, this study highlights the importance of having a holistic outlook when analyzing resource-based competitive advantages.

    Flexibility in assembly systems using product design2017Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Growing customer demands for product variety, new and rapid technological developments, and the short life cycle of products characterise the current volatile market. To maintain a competitive edge in the market, manufacturing companies need to accommodate flexibility in their assembly systems that are essential parts of the manufacturing systems with respect to cost, time, and creating product variety. Given the importance of establishing flexible assembly systems, the complexity raised by increasing product variety and the value of appropriate product designs to assembly systems highlight the pivotal role of product design in a flexible assembly system. Despite its significance to theory and practice, however, the characteristics of flexibility in an assembly system and its links to product design are still ambiguous and unexplored.

    The objective of this thesis is to expand the current knowledge of flexibility in assembly systems and using product design to support its achievement. To accomplish the objective and by adopting an interactive research approach, five case studies were conducted in the heavy machinery manufacturing industry. A literature review underpins all the case studies comprising one multiple and four single case studies.

    Through its findings, this research defines flexibility in an assembly system, identifies its dimensions, and pinpoints its enablers. Additionally, three requirements of a flexible assembly system for product design are identified: a common assembly sequence, similar assembly interfaces, and common parts. These requirements, if fulfilled in product design across distinct product families, reduce the perceived complexity and support various flexibility dimensions in the assembly system. Moreover, the development of a common assembly sequence and similar assembly interfaces, as the two key requirements of a flexible assembly system for product design, is described.

    Further, based upon developing understanding and knowledge about a flexible assembly system and its requirements for product design, a model and a framework are proposed. The model addresses the role of product design in achieving flexibility in an assembly system. To support the alignment of product design with the key requirements of a flexible assembly system during the product design process, the assembly-oriented framework details the development of these requirements. Through its outcomes, this thesis contributes to the research area of flexible assembly systems and sheds light on its interface with the engineering design field. Moreover, the proposed model and framework aim to assist assembly practitioners and product designers in establishing a flexible assembly system and aligning product design with its key requirements.

    Supporting flexibility in an assembly system through product design2015Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Increasing customer demands for product variety in conjunction with the short lifecycle of products has caused manufacturing companies to introduce a wide range of products by accommodating flexibility. An assembly system is an essential part of the manufacturing system from both cost and time perspectives. Hence, the shift towards flexibility in manufacturing companies highlights the significance of establishing flexible assembly systems and designing products that are closely aligned with them. Despite its significance, however, the flexible assembly system concept and its requirements for product design have not been clearly defined in research and from a practical point of view. Most research on flexible assembly systems has mainly approached either the design or the balancing and scheduling issues of these systems, whereas only a few studies have briefly defined the flexible assembly system they focused on, without further specifying the characteristics of a flexible assembly system and its requirements for product design.

    Taking that into account, the objective of this work is to provide a framework to contribute to the understanding of the concept of flexibility in an assembly system and its requirements for product design. In order to fulfil the objective, four empirical studies combined with literature reviews have been conducted. The empirical studies, a multiple case study and three single case studies, investigate the definition of flexibility in an assembly system as well as the requirements that a flexible assembly system imposes on product design.

    Through its findings, this research provides a definition of flexibility in assembly systems that mainly revolves around volume, mix and new product flexibility. In addition, six constituents of a flexible assembly system have been identified: adaptable material supply, versatile workforce, increased commonality, standardised work content, integrated product properties and strategic planning. Furthermore, three requirements of a flexible assembly system for product design are defined, which, if fulfilled, reduce the complexity created by product variety and consequently support flexibility in the assembly system. Accordingly, to increase the understanding of the concept of flexibility in an assembly system and its requirements for product design, a four-staged framework is suggested. The proposed framework deals with the activities related to the concept and the development of a flexible assembly system and is expected to be received by assembly practitioners as a link between assembly and product design teams in the product realisation process. Future research can further validate the framework in practice.

    The Essential Constituents of Flexible Assembly Systems: A Case Study in the Heavy Vehicle Manufacturing Industry2015Ingår i: Global Journal of Flexible Systems Management, ISSN 0972-2696, Vol. 16, nr 3, s. 235-250Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The major challenge of today’s manufacturing industry in tackling demands for a wider range of products with short life-cycle times and meeting customisation requirements has drawn considerable attention towards flexibility in manufacturing systems. As a prominent part of a manufacturing system, an assembly system provides a platform for increasing efficiency while delivering various market demands. However, owing to the dearth of a unified and clear definition of the constituents of flexible assembly systems, in both theory and practice, the recognition of flexibility in assembly systems still remains elusive. In order to establish a sound base for discussing the constituents of flexible assembly systems, this research paper explores the literature concerning flexibility in manufacturing and assembly as well as in flexible systems management domains. To reflect an industrial perspective, a multiple case study of five manufacturing plants in the heavy vehicle industry is performed. By identifying six essential constituents of flexibility in assembly systems, the study proposes a clear definition of flexibility in assembly systems which mainly revolves around mix and volume flexibility. To further enhance the findings, the compatibility of a few previously identified types of manufacturing flexibility in the assembly systems of the case plants is investigated and additional dimensions of flexibility in assembly systems are revealed. Finally, the implications for theory and practice as well as suggestions for future research are discussed.

    Success factors of an ipd based approach in a remote multidisciplinary team environment - Reflections on a case study2017Ingår i: Proceedings of the International Conference on Engineering Design, ICED, Design Society , 2017, nr DS87-9, s. 31-40Konferensbidrag (Refereegranskat)
    Abstract [en]

    Integrated Product Development (IPD) is comprehensively discussed in literature. The human-centered approach offers a parallelized set of work activities in interdisciplinary teams. Due to the rapid globalization of IPD activities in the companies, project members are often obliged to work remotely in teams and through virtual means of communication. However, with the recent shift towards working remotely in IPD teams new challenges have emerged that might adversely affect the success of IPD projects. The objective of the paper is to outline the key factors strengthening and weakening the IPD process in a remote multidisciplinary team environment. To fulfill the objective, a case study on an international multidisciplinary team of postgraduate students working on a design project with an IPD approach, was conducted. The results highlight key success factors and their contributions to the project success in a remote multidisciplinary team environment. Additionally, key weaknesses of such approach and their negative impacts are also indicated.

    An assembly-oriented product design methodology to develop similar assembly operations in a mixed-product assembly line2017Ingår i: Proceedings of the International Conference on Engineering Design, ICED, Design Society , 2017, nr DS87-5, s. 131-140Konferensbidrag (Refereegranskat)
    Abstract [en]

    With the growing demands for product variety, Mixed-Product Assembly Lines (MPALs) as an effective means of creating product variety are recently increasing in manufacturing companies. However, handling different products from distinct product families creates high complexity in performing assembly operations in an MPAL. The elevated complexity, calls for increased similarity between assembly operations in an MPAL which requires product design changes accordingly. Hence, the objective of this paper is to suggest an assembly-oriented product design methodology to increase similar assembly operations for various products cross-product families. The proposed methodology uses Interface Diagram, a product architecture modelling tool, for comparing assembly operations crossproduct families, suggesting an assembly-oriented design, and communicating it to designers. The methodology has been developed by conducting a case study in heavy vehicle manufacturing industry. The results highlight a visual approach towards establishing a common language between assembly and design teams to consider the requirements of an MAPL in product design.

    Drivers of complexity in a flexible assembly system- A case study2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    Various ever-changing market demands have propelled manufacturing companies to offer product variety in an efficient and timely manner. Assembly as a key stage of manufacturing process is used to realise product variety through establishing mixed-product assembly systems. Although establishing a flexible mixed-product assembly system which both offers product variety and absorbs market demands fluctuation is pivotal for maintaining competitive edge in certain industries such as vehicle manufacturing, it is also considered an elaborate task which calls for further investigation. In this paper, complexity in a flexible mixed-product assembly line is investigated and the key drivers of complexity are identified. To fulfil the research objective, a case study during the pilot implementation of a flexible mixed-product assembly concept in a heavy vehicle manufacturing company has been conducted. The results indicate the key factors concerning assembly process, product design, and information and communication technology (ICT) which contribute to complexity in the flexible assembly system. The paper concludes with an outlook for possible future research.

    Handling product variety in a mixed-product assembly line: A case study2015Ingår i: DS 80-4 PROCEEDINGS OF THE 20TH INTERNATIONAL CONFERENCE ON ENGINEERING DESIGN (ICED 15) VOL 4: DESIGN FOR X, DESIGN TO X, 2015, Vol. 4, s. 41-50Konferensbidrag (Refereegranskat)
    Abstract [en]

    In today’s fast-changing global market, using mixed-product assembly lines (MPALs) and mixed-model assembly lines (MMALs) allows manufacturing companies to be flexible and to maintain their competitive edge through product variety. Balancing and sequencing issues have been recognized as the main challenges of MPALs and MMALs, but other practical needs of MPALs remain unclear. Recognizing the practical needs of MPALs helps in identifying related requirements for product design, leading to products that closely align with the MPAL concept. The objective of this paper is to offer an industrial perspective on the needs of MPALs and to identify its requirements vis-à-vis product design. To achieve this objective, a single real-time case study in a heavy-vehicle-manufacturing company has been performed. The results from this industrial case study suggest that in order to handle product variety in MPALs and to reduce the related complexity, certain dimensions of flexibility need to be created in the assembly system, and requirements related to product design should be considered simultaneously in order to support assembly processes.

    Identification of the causes of complexity in mixed-product and mixed-model assembly lines2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    The increasing demands for product variety have directed manufacturing companies towards accommodating flexibility by establishing mixed-product and mixed-model assembly lines. However, since greater variety leads to increased complexity, establishing these assembly lines becomes complicated. By conducting a case study, this paper investigates the causes of complexity and the applicability of assembly instructions in one mixed-product and four mixed-model assembly lines in a heavy vehicle manufacturing company. The results indicate a set of causes for complexity and highlight the significance of assembly instructions, as the practical implications for development of flexible assembly systems and design of products closely aligned with them.

    Considering assembly requirement specifications in product development: identification and approach2014Ingår i: FAIM 2014 - Proceedings of the 24th International Conference on Flexible Automation and Intelligent Manufacturing: Capturing Competitive Advantage via Advanced Manufacturing and Enterprise Transformation, 2014, s. 969-976Konferensbidrag (Refereegranskat)
    Abstract [en]

    Due to the major advantages such as reduced time to market and improved quality at lowered cost, the principles of design for assembly capabilities and concurrent engineering are of great significance when developing new products. However, identifying assembly requirement specifications and considering them in New Product Development (NPD) in a timely manner, while securing efficiency and robustness of assembly processes, still remains a challenging task. In presenting a case study of an NPD project in a manufacturing company, this article focuses on the process of capturing and incorporating the requirements related to the assembly system during the early phases of NPD. Further, the results of the research study indicate the different assembly requirements in the case company and pinpoint the challenges in practices involved in handling them. The assembly requirements identified in this research reflect some of the challenges encountered in handling the requirements, through the investigated requirement practice. Based on the results, the issues of when and how to consider the assembly requirements are highlighted in the conclusions and suggestions for future research are made.

    Factory-in-a-Box: an Enabler for Flexibility in Manufacturing Systems2006Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    AT PRESENT, many markets are characterized by a fast pace of change, as well as a high internationally enlarged competition. Since the conception of Mass Customization emerged in the late 1980´s, many companies within the manufacturing industry have been striving to fulfill this vision by increasing the flexibility within their manufacturing system. However, although there are many manufacturing theories that describe theoretical solutions to mass customization, but there is still a lack of practical enablers that can realize the conception.

    In January 2005, the Swedish Foundation for Strategic Research started the project Factory-in-a-Box. There, the key characteristic is to realize is the concept of modular production units that are flexible, mobile and quick to ramp-up. This licentiate thesis is a part of the Factory-in-a-Box project, and its objective is to investigate if and how the Factory-in-a-box concept is an enabler to realize flexibility in manufacturing systems.

    The outcome of this research work indicates that the Factory-in-a-Box concept is a plausible solution that goes in line with previous research and future challenges within the manufacturing industry. The Factory-in-a-Box concept offers possibilities for a more flexible and responsive manufacturing system, which also unwrap new business possibilities, increased automation, and entering new markets. To succeed in implementing the Factory-in-a-Box concept in a manufacturing system some key generic requirements have been identified.

    The research project concludes that mobile manufacturing systems in general and the Factory-in-a-Box concept in particular offer new possibilities to the manufacturing industry. Also, the concept is not limited to the manufacturing industry, there are a wide range of applications where the concept could be useful, for example within the construction industry.

    Monteringsstation för verktygstavlor: Konstruktion och framtagning av monteringsinstruktion2018Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Detta examensarbete har gjorts med Husmuttern AB som uppdragsgivare. Husmuttern AB är ett företag i uppstartsfasen som utvecklar modulhus som ska vara återvinningsbara, demonterbara och standardiserade.

    Examensarbetet går ut på att konstruera en monteringsstation för mobila verktygstavlor till en Husmuttern-fabrik. Det ska även finnas instruktioner till stationen. Tavlorna används som förvaring för verktyg, säkerhetsattiraljer m.m. Stationen ska kunna användas av människor utan yrkeserfarenhet och oavsett språkkunskaper och bakgrund.

    Forskningsfrågorna är:

    * Hur ska instruktionerna utformas så att personer oavsett språklig bakgrund kan förstå dem?

    * Vilka faktorer är de mest avgörande när det gäller ergonomi och skydd mot felmontering?

    Metoden som använts baseras på produktutvecklingsprocessen som beskrivs i Produktutveckling av Ulrich, K och Eppinger, S (2012), men är anpassad till det aktuella projektet.

    För att få en färdig verktygstavla behöver man montera alla krokar och annan förvaring på tavlorna och därefter montera tavlorna på ben så att den blir mobil. För att alla krokar, muttrar m.m. ska hamna på rätt plats på tavlorna har man använt hålmallar som visar var varje del ska sitta. Till benen används en fixtur som man ställer benen i, lägger i tavlorna i rätt ordning och skruvar fast dem.

    Instruktionerna är i form av en powerpoint-presentation som spelas upp på tv-apparater i fabriken. Instruktionerna innehåller bilder och video som visar varje moment i monteringen. De innehåller också symboler som t.ex. pilar som ska uppmärksamma viktiga detaljer. Instruktionerna innehåller ingen löpande text, den enda skrift som finns är siffror, vilka arbetarna förväntas förstå.

    Projektgruppen har gjort tester med arbetare i fabriken. Testerna har visat att konceptet fungerar. Hålmallarna i kombination med instruktionerna gör att arbetarna enkelt förstår var alla delar ska monteras. Fixturen för benen har inte testats på arbetarna i sin slutgiltiga form men konceptet har testats och det fungerar tillfredsställande.

    Product cost analysis in early stages of a product development process2013Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    På en global marknad med allt tightare vinstmarginaler har fokus på produktkostnad ökat. I produktutvecklingsprocessen har ett allt större behov av förbättrade arbetssätt kring produktkostnadskalkylering uppstått för att företag skall vara konkurrenskraftiga.

    Produktkostnad är en väsentlig del av ett företags kostnadsmassa. Under en produktutvecklingsprocess tidiga skeden saknas ofta etablerade metoder och processer för beräkning av produktens kostnad. Speciellt svårt är det att uppskatta produktkostnad i tidiga faser av produktutvecklingsprocessen då osäkerheten kring konstruktionen är stor. Detta kan få till följd att till exempel avsaknad av vetskap kring materialkostnad eller investeringsbehov uppstår. Målet med denna uppsats är att hjälpa, utvärdera och supportera kring förbättringar av arbetssätt inom produktutvecklingsprojekten när det kommer till produktkostnadskalkylering.

    Syftet med detta examensarbete är att skapa en passande finansiell modell som kan användas vid val av koncept i tidiga stadier av produktutvecklingsprocessen för att säkerställa högsta möjliga lönsamhet för Volvo Construction Equipment. För att lösa detta problem så har insamling av teori i form av böcker, artiklar samt rapporter genomförts med fokus på produktutveckling och produktkostnad. Teoristudien påvisade mycket material kring produktutvecklingsprocessen men mindre kring detaljerad produktkostnadskalkylering. Den empiriska delen har genomförts i samarbete med Volvo Construction Equipment med syfte att få ökad förståelse för problemställningar i dess verkliga miljö. Från intervjuer, dokumentation samt övrig insamling så påvisades att förbättringspotential fanns kring produktkostnadskalkylering i tidiga faser av produktutvecklingsprojekt.

    För ytterligare ökad förståelse genomfördes en strukturerad jämförelse samt en diskussion kring respektive område av teori och empiri. Resultatet av jämförelsen visar att Volvo Construction Equipments hantering av problem korrelerar med den teori som existerar i uppsatsen. I de situationer där Volvo avviker från teorin så finns orsaker till att företaget inte väljer att följa denna.

    För att förbättra processen kring produktutveckling och produktkostnadskalkylering på Volvo Construction Equipment skapades en kalkylmodell. Modellen applicerades konkret i ett pågående produktutvecklingsprojekt i företaget och gav möjlighet till uppföljning av utvecklingen av produktkostnaden under de olika faserna av projektet.

    Solving the quality dilemma: Emergent quality management2017Ingår i: International Series in Operations Research & Management Science, Volume 255, Springer New York LLC , 2017, s. 151-166Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    The Emergent Quality Management paradigm combine the two sides of the dichotomy imposed by the dilemmas of the production system: on the one hand side exploitation, stability, control and efficiency and, on the other hand, exploration, adaptability, creativity and effectiveness. The two sides—actors’ exploration and the structures of exploitation—are interconnected and reinforce each other. Actors and structures are always interconnected with each other in a circular causality. It is through the interactions between the actors that the structures emerge, and these structures organize the activities of the actors. The conflict in goals between exploration and exploitation at individual and team levels is thus transcended. This is a theoretical transcendence, meaning that by using the Emergent Quality Management paradigm it becomes obvious that the dichotomy is not a problem that must be managed, but a necessary feature of wholeness.

    Abstract [en]

    In this concluding chapter, each of the previous chapters are reflected upon based on the emergent quality management paradigm presented in Chap. 9 by Backström. This book introduces four processes: innovation, production, knowledge creation, and value creation processes. It is emphasised that companies must prioritise and develop all four of these processes to survive and prosper. Throughout the book, dichotomies associated with these processes have been elaborated on and discussed. Historically, these dichotomies have often created dilemmas owing to the current understanding of their relations. However, as suggested in this book, alternative perspectives can be used in a constructive way to resolve these potentially high-impact dilemmas. Recognising the dichotomies as mutually dependent gives further possibilities for the development of production systems.

    Abstract [en]

    It is well known that the development of successful business and production systems are full of conflicting forces; initiatives that seem conducive to one line of work can be a constraint on another line of work. This kind of dilemma is the core subject of the current book, and by applying alternative perspectives to such dilemmas, the book will present ideas on how these could be managed in organizations. Organizations need to manage a number of challenges in terms of dualities in order to create a contemporary production system, which seems to be key to future innovative quality improvements in operations. The challenges and dichotomies that are addressed in this book are all part of four interrelated processes that together constitute key elements of a contemporary production system: The innovation process—creation and implementation of new offerings and solutions, The production process—production and distribution of offerings and solutions, The knowledge creation process—emergence and distribution of knowledge, The value creation process—created customer value based on the offerings and solutions developed.

    Simulating the emergence of the organizing structures of work2014Konferensbidrag (Refereegranskat)
    Abstract [en]

    —This article is a first step toward a visualization and classification system for studying dynamic organizing structures of work. As a first step toward this researchobjective, this study brings together two active projects. One called “relatonics” studies work group formation and is primarily empirical and inductive. The other called “Human Interaction Dynamics (HID)” imports concepts, relationships and modeling from complexity science and is therefore primarily theoretical and deductive. The vision is to use social media, data gathering, and process simulation technologies to rigorously describe, systematically visualize, and validly model the complex dynamics of work processes of different types. This work will serve as a means to classify, study and improve the performance of work systems. We describe our progress to data and suggest further research.

    Readiness Assessment Framework for Transfer of Production Systems - A Case Study2018Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Introduction

    The implementation or transfer of production systems from the developing organisation to the receiving can induce difficulties, however a connection between achieving readiness of the receiver within the context of PSD has not been investigated previously. The aim of this thesis is thus to examine PSD in a core plant environment, focusing on the transfer activity and readiness for change. The following research questions were asked:

    • How can assessing readiness potentially benefit a PSD project?
    • How can preparation for transfer ensure readiness of the receiving organisation?

    Methodology

    A case study was performed and a company was selected due to a recently performed PSD project where the company went from a tradition line-based production to digitalised cells. The thesis is within the COPE research project; thus, some emphasis is on the global aspect. This exploratory and descriptive research study both examines and describes the studied phenomenon. The case study approach enabled the identification of organisational and human factors within the PSD project. Data collection contained interviews and a literature review was performed.

    Theoretical Framework

    A literature review was performed which provides insights regarding a general approach to a PSD process. Furthermore, core plant role and the strategic position within the network are described. Other investigated areas are within transfer of; processes, production and knowledge as well as prerequisites for those activities. Maturity assessment models are also introduced to provide an insight on assessing an organisations current state and to establish improvement strategies. An overview of competences which are required in an Industry 4.0 context are presented. Individual and organisational effect on change are presented as well as how change can be combated.

    Empirical Findings

    The empirical findings provide an overlook of the current manner in which PSD projects are executed, foremost by investigating a recent PSD project. The investigated aspects were more concretely regarding the need for a readiness assessment, and readiness to transfer a PSD project from the developing to the receiving organisation. Motivation to change and change management were also identified. Lastly, replicability within the core plant context were examined.

    Analysis and Discussion

    Possible benefits of a readiness assessment are identified, which are creation of a holistic view, alignment of vision, standardisation need and communication among other things. Participation and assignment of responsibility are also identified as lacking within the case company which is an essential asset within a PSD project. Lastly a framework is developed which can possibly guide the PSD process in achieving readiness for change.

    Conclusions and Recommendations

    Multiple benefits of a readiness assessment are identified which emphasises the human and organisational aspects of a change implied by a PSD project. The technical focus identified in the case company can be combated by acknowledging soft variables and skills and by understanding the decisions behind solutions. A framework is developed for Readiness Assessment with a focus on contesting the lack of responsibility and a “we against them” attitude. The mission of the framework is to create alignment and collaboration.

    Bedömning av tillverkningmetoder med MRL2016Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Today´s industry is driven into development by an increasingly difficult situation of competition that gives less room for miscalculations in the production. One of the most important factors in maintaining your competitiveness is your ability to quickly and efficiently adopt new methods of manufacturing. With the help of new manufacturing methods, the company can improve product design, add new value creating features, and get a faster and more flexible production. However, problems arose with the grading of new manufacturing methods, in order to understand their matureness and if they are ready to be taken into production. This paper aims to investigate the possibility of a rating scale for manufacturing methods and then test this scale on a case study at Volvo CE, Eskilstuna, regarding their introduction of the method Power Skiving in their gear manufacturing.

    Through studying secondary data regarding already applicable methods for rating of the maturity of technologies and products that are to be introduced into production. Furthermore, have articles regarding proposed methods of rating the maturity of manufacturing methods been revised in order to get an insight into the current situation of rating manufacturing methods and to see what in specific could be of usefulness in rating manufacturing technologies.

    Beyond secondary data interviews have been conducted with the division of production development at Volvo CE Eskilstuna and with the Director Global Manufacturing Technology at Volvo CE. With the goal of gaining information regarding what they consider crucial in rating manufacturing methods and what is of importance in order to make this rating scale useful in the everyday work. Visits have been made in the production of slewing rings at Volvo CE in order to be able to gather data for the case study regarding the possible introduction of Power Skiving in Volvo CE´s gear manufacturing.

    The Authors have been able to construct certain criteria that aim to support todays rating matric of introduction of new products in order for it to also work for rating the readiness of new manufacturing methods. Today rating scales for manufacturing methods aren’t widely accepted, the authors, however, assume that it will gain acceptance and there will be more research regarding this subject.

    Further studies regarding documentation of the ratings and how this rating could be further integrated into daily operation at a company is recommended.

    Functional Safety in Product Lines - A Systematic Mapping Study2016Ingår i: 42nd Euromicro Conference series on Software Engineering and Advanced Applications SEAA 2016, 2016, s. 313-322Konferensbidrag (Refereegranskat)
    Abstract [en]

    Software product line engineering is a widely used approach to plan and manage reuse of software. When safety critical products are developed, achieving functional safety standard compliance must be shown. The requirements stated in the functional safety standards also apply when safety critical products are developed in product lines. Managing functional safety in industrial product lines is challenging and work around solutions are applied in practice. The objective of this research is to collect and review reported research publications focusing on achieving safety in product lines and to identify gaps in todays research. We conduct a systematic mapping study of research publications reported until January 2016.We identify 39 research articles to be included in a list of primary studies and analyze how product lines are documented, which safety-related topics are covered and which evaluation method the studies apply. Generally, we find that the area of how to achieve functional safety in product lines needs more attention. Our study provides an overview on which topics have been discussed until now and which safety-related topics need more attention.

    Industrial Challenges to Achieve Functional Safety Compliance in Product Lines2014Ingår i: 2014 40TH EUROMICRO CONFERENCE SERIES ON SOFTWARE ENGINEERING AND ADVANCED APPLICATIONS (SEAA 2014), 2014, s. 356-360Konferensbidrag (Refereegranskat)
    Abstract [en]

    Developing safety critical products demands a clear safety argumentation for each product in spite of whether it has been derived from a product line or not. The functional safety standards do not explain how to develop safety critical products in product lines, and the product line concept is lacking specific approaches to develop safety critical products. Nonetheless, product lines are well-established concepts even in companies developing safety critical products. In this paper we present the results of an exploratory study interviewing 15 practitioners from 6 different companies. We identify typical challenges and approaches from industry and discuss their suitability. The challenges and approaches brought out by this study help us to identify and enhance applicable methods from the product line engineering domain that can meet the challenges in the safety critical domain as well.

    A corporate perspective on global management and development of lean production systems: A case study2014Ingår i: Handbook of Research on Design and Management of Lean Production Systems, IGI Global, 2014, s. 270-289Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    The challenge for every multinational manufacturing company with the ambition to implement the lean production concept is how to implement it worldwide within its global manufacturing footprint. There are many decisions that need to be taken from a company group perspective when planning and implementing a lean program. These concern the level of standardization on principles and tools, how to structure and organize additional resources, how to share experiences within the organization, and how to sustain the effort. These factors are elaborated in this chapter from a factory perspective based on the presentation of the lean journey of Gyproc AB, a process industry company within the Gypsum part of the large Saint Gobain group. The company has worked for about ten years with implementing world-class manufacturing and has extensive experience of the issues of starting-up and sustaining the lean-based concept.
