    Revisiting challenges in using Discrete Event Simulation in early stages of Production System Design2018In: International conference of advances in production management systems APMS, Springer, 2018, Vol. 535, p. 534-540Conference paper (Refereed)
    Abstract [en]

    This paper presents challenges of using discrete event simulation when supporting decision in early stages of production system design, when significant changes are introduced. It was based on three real-time case studies performed at one manufacturing company during 2014-2016. Challenges in the cases were mapped to previous literature, pointing out discrepancies and highlighting three additional challenges, specifically related to issues in the early stages of the pro-duction system design process. The significant change introduced to the assembly system, and the early phases of evaluation put significant challenges to the use of discrete event simulation and the study points out further efforts needed to support manufacturing companies under change, with an established industrial structure and legacy systems to consider.

    Visual awareness aiding communication2020In: International journal of visual design, ISSN 2325-1581, Vol. 14, no 2Article in journal (Refereed)
    Abstract [en]

    Visual awareness is essential to developing and implementing visualizations that meet the needs of cross-functional teams. The theoretical and practical domain of information design can potentially play a major role in such collaborative working processes by improving flows of relevant information and aiding communication between stakeholders. We argue that one way this can be achieved is by exploiting the boundary object concept, in combination with knowledge from the visual field, and recommending guidelines intended to help clients formulate requirements when planning factory layouts which, with appropriate modification, may also provide support in similar situations. Our suggested guidelines for constructing block layouts and diagrams in factory layout planning highlight the value of simple visualizations based on spatial relationships; utilizing information on available spaces, sizes of machines, and their relationships to human proportions. Such block layouts and diagrams can also be used for ergonomic planning and logistics. The visuals can act as boundary objects between various stakeholders, including those who create CAD models in VR environments.

    Learning via “Nattljus” 2018: A report on co-creation and learning in Spatial Design-Information Design education, developed as part of the activities produced in conjunction with Mälardalen University Living Lab2019Report (Other academic)
    Abstract [en]

    Learning via “Nattljus” 2018 reports an example of co-creation and learning, developed as part of the activities produced in conjunction with MDH Living Lab in 2018. This project was designed as an integrated part of the Bachelor’s course Ljus och ljud (Light and Sound), 7.5 credits, that was given at Mälardalen University in the autumn. The project was initiated by Eskilstuna Municipality and is a part of the biennial light festival, running for its third time.

    The collaboration included a LED light specialist company from Stockholm, Zumbotel Group, the Municipality of Eskilstuna and an independent external light designer with connections to KTH (the Royal Institute of Technology). The methods for the collaborative project were mainly practical, based on workshops and labs in a studio environment, as well as on site. It was mixed with experience-based lectures given by external experts: from the municipality, the lighting company and a light designer, this was iterated with integrated design and theory lectures on site, by the course leader and the involved researcher, connected to MDH LL.

    This led to a comprehensive integration of the course content and practice-driven processes enabling collaborative learning in a real setting that information designers with spatial design skills might encounter in their coming professional lives.

    Processer och metoder som möjliggör för en effektiv produktframtagning2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The high level of competition and the rapidly growing technology development has created new challenges for today's businesses where they are forced to deliver more customized products at a lower price and a shorter time period. This places high demands on the companies' ability to design and develop better products in a more efficient way. In addition to developing products, the design process focuses on securing long-term success for the company by developing nourishing skills. However, to achieve an effective design process the companies must improve their ability to plan as well as use their knowledge base in a more efficient manner. Toyota's product development system is a critical component for companies to address challenges that they’re facing and offers a great potential to create significant competitive advantages. Toyota's product development system is designed to streamline the design of processes and products, as they often create restrictions on business and describes the importance of making use of a coordinated effort by several functions, and strives to integrate processes, people, technology and tools in an effective manner.

     

    The concept of Concurrent Engineering includes parallel efforts rather than a time-consuming serial work and seeks to minimize delays in the product development process. Concurrent Engineering enables for quality products, to reach the market faster at a lower cost and allows the company to quickly and flexibly adapt to changing demands and conditions through parallel efforts. Like Toyota’s product development system, Concurrent Engineering promotes an integrated approach where multifunctional teams work towards a common goal striving to solve problems at an early stage.

     

    Propulsion and Control in Västerås, a division within Bombardier Transportation, is currently suffering from extensive engineering changes and struggles to uphold time plans and budgets. The thesis will therefore cover the complete product development process where focus has been directed towards the processes and conditions that could enable for an effective product development process. During the thesis work the underlying causes for the problems mentioned above, have been identified. Internal documents regarding the company's current process has been reviewed and interviews have been carried out in order to evaluate the company’s current situation. During the thesis work a comparative study has been conducted at a large company within the Mälardalen-region. This study has been used as a practical example to reinforce the theoretical reasoning and has additionally allowed for further examination of a company's product development process.

     

    The thesis has resulted in a number of suggestions for improvements, where the main action areas are covered by cross-functionality, routines, follow-up, supplier involvement and prototypes. Another action area that has been identified is front-loading which aims at examining several alternatives and solving problems as well as creating countermeasures at an early stage. These six areas were found to have a significant role in creating an effective product development process and are considered to be relevant for the company's current situation.

    Supporting Production Ramp-Up with Knowledge Management & Competency Modeling: A study on how to support higher productivity and better employee working conditions2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study is to describe how competency modeling and knowledge management can support a ramp-up of an existing complex production.

    An abductive study approach is used, to keep the study open for new directions to generate new theories. A case study is done at ABB Machine, followed by two reference cases at Scania and Volvo. Semi-structured interviews are used together with observations to get qualitative data. A conceptual framework is used in the interviews to easier connect the data to the theoretical framework. The data is compiled and analyzed with a thematic approach. Empirical and theoretical data is separately analyzed, followed by a discussion how they could support a ramp-up process.

    Results showed that competency modeling and knowledge management together support a ramp-up better by improving knowledge transfer and flexibility. Flexibility is created from strategic modeling where personnel hold several competencies which enable for greater adoption to existing production. With proper knowledge transfer, new staff can be introduced more efficiently, and experienced ones can broaden their competencies furthermore. Also, it gives effects such as better work mood, new approaches on matters and less ergonomic injuries. The results also showed the importance of time required for transfer, which if not respected can effect ramp-up quality negatively. The recommendations for complex factory production is to use more competence broadening, comply with the time needed, have skilled trainers, and collective goals for the whole organization.

    Strategies for emergent quality management2018In: Participatory Innovation Conference 2018 PIN-C 2018, 2018, p. 14-20Conference paper (Refereed)
    Abstract [en]

    This paper explores strategies for emergent quality improvement, which involve managing both efficiency and effectiveness, or the 'quality dilemma'. An empirical investigation is conducted with seventeen quality managers, representing organisations in ten private companies and one organisation in the public sector. The results indicate five distinct themes of importance to manage the quality dilemma: 1) leadership, 2) the quality organisation, 3) prioritisation, 4) knowledge and competence, and 5) the quality profession. While the dilemmas are categorised into five distinct and critical themes, the second part of the results present tactics regarding how to move positions towards emergent quality management: perspectives, processes, and decision support. The conclusions imply that the current method of organising quality improvement must be revised.

    Abstract [en]

    The development of successful production systems is affected by conflicting forces, that is, initiatives seemingly conducive for one line of work can be a constraint for another. Consequently, this paper presents an alternative perspective on how these issues could be managed in organisations. There are a number of key challenges in terms of the involved dichotomies for future innovative quality improvements in operations. These dichotomies are part of four interrelated processes that are the central elements of a production system. As such, aiming for stability or change is a production process dilemma in terms of the production and distribution of offerings and solutions. Control and creativity are the main dilemmas of the innovation process, that is, the creation and implementation of new offerings and solutions, while exploitation and exploration are the dilemmas of the knowledge creation process and efficiency and effectiveness of the value creation process. As the simultaneous existence of both parts of the dichotomy seems to be a paradox, this paper suggests the emergent quality management paradigm as an alternative perspective providing the guidance, examples, and practical solutions necessary to solve these dilemmas by recognising the dichotomies as mutually dependent.

    The quality dilemma: Combining development and stability2017In: International Series in Operations Research & Management Science, Volume 255, Springer New York LLC , 2017, p. 9-33Chapter in book (Refereed)
    Abstract [en]

    The objective of this chapter is to problematize the strategic management of both efficiency and effectiveness through quality management. First, the chapter describes five cases with lessons learned from the dichotomy of efficiency and effectiveness on how quality management could be turned into either a constructive or a destructive dilemma. Then, the history of the quality movement and how it has developed during the last century is discussed briefly. Quality management will be considered in relation to organization theory regarding exploration, exploitation, and dual organizational capabilities. Finally, the chapter concludes with proposals on ways forward for quality management as a strategy for both short-term efficiency and long-term effectiveness and survival.

    Continuous learning using dissatisfaction feedback in new product development contexts2010In: International journal of quality and reliability management, ISSN 0265-671X, Vol. 27, no 8, p. 860-877Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to explore how various dissatisfaction feedback transferrals contribute to the decision-making process in product development contexts. Design/methodology/approach – The paper presents the results from a qualitative interview-based study of 16 product development organizations and their customer dissatisfaction feedback systems; 84 percent of the companies within a machine industry segment in Sweden are covered. Findings – Based on the empirical investigation, a taxonomy of five decisions based upon dissatisfaction feedback is developed: reactive, preventive and developmental decisions are connected with exploitation of products, while future developmental and future preventive decisions are connected with exploration of future products. Originality/value – The project is essentially managerial, aiming to provide managers and other decision makers with a framework that displays how various dissatisfaction feedback transferrals contribute to various decisions in product development contexts. The paper highlights that despite costly investigations in customer feedback systems, very few customer dissatisfaction feedback transferrals are connected to explorative future developmental actions.

    Quality 2030: quality management for the futureIn: Total Quality Management and Business Excellence, ISSN 1478-3363, E-ISSN 1478-3371Article in journal (Refereed)
    Abstract [en]

    Quality management (QM) has shown an impressive ability to update and evolve. The purpose of this paper is to highlight themes that have been identified as vital and important for research projects within QM during the coming decade. The paper is also an attempt to initiate research for the emerging 2030 agenda for QM, here referred to as 'Quality 2030'. This article is based on extensive data gathered during a workshop process conducted in two main steps: (1) a collaborative brainstorming workshop with 22 researchers and practitioners (spring 2019) and (2) an appreciative inquiry summit with 20 researchers and practitioners (autumn 2019). The process produced five collectively elaborated and designed future research themes for QM: (a) systems perspectives applied, (b) stability in change, (c) models for smart self-organising, (d) integrating sustainable development, and (e) higher purpose as QM booster. The process also identified a positive core of QM, defined as core values and aspects in the field and practice that need to be preserved and nurtured in the future.

    A Framework to Incorporate Industry 4.0 into SME to Enhance Resource Planning2020Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Small and Medium-sized Enterprises (SMEs) have grown steadily in recent years.  SMEs generate 59.7 % of value-added and 65.5 % of employment in the ‘non-financial business economy’ in Sweden. It's important for the success of SMEs to be ready to provide high product availability to customers at minimal operation costs. The challenges faced by SMEs are tougher in global competition. There is a rapid growth in the industrial revolution to deal with the challenges as well as competition. This work mainly focuses on implementing resource planning (RP) and adapting to the latest technologies of Industry 4.0 into SMEs to face the challenges. But incorporating Industry 4.0 in a major struggle in the SMEs. 

    The thesis provides a view of Resource Planning implementation. The authors describe the resource planning implementation techniques and define the requirements for its successful implementation. Resource Planning (RP) adoption factors have been studied quite extensively over the years. However, this master thesis tries to investigate the less explored area of resource planning. Relatively a smaller amount of research has been conducted, when it comes to implementation of Industry 4.0 technologies especially in Small and Medium-sized Enterprises (SMEs). 

    Industry 4.0 provides new paradigms for the industrial management of SMEs. Supported by a growing number of new technologies, this concept appears more flexible and less expensive than traditional enterprise information systems. This paper presents a literature review of existing applied research covering different Industry 4.0 issues about SMEs.

    Furthermore, the analysis is done to understand the correlation between the identified factors of Industry 4.0 technologies. The research findings indicate that the use of IoT and Cloud computing are major advantages for resource planning in an SME. The results from the analysis are presented in a framework designed for the future adaptation of these technologies. Despite the research limitations, the findings show a high advantage. Finally, the author suggests a future scope of research.

    Perspectives on Smart Maintenance Technologies – A Case Study in Small and Medium-Sized Enterprises (SMEs) Within Manufacturing Industry2023In: 16th WCEAM Proceedings, Springer Nature , 2023, p. 571-585Conference paper (Refereed)
    Abstract [en]

    Industry 4.0 consists of nine technological pillars: IIoT, Cloud Computing, Big Data and Analytics, AR, etc. Some of the pillars play an essential role in maintenance development. Previous research presents many technologies for smart maintenance, but one prevailing problem is that there are still challenges to implementing smart maintenance technologies cost-effectively in the manufacturing industry. Therefore, we explore perspectives on smart maintenance technologies from respondents within 15 manufacturing SMEs. We start by investigating whether the companies had implemented smart maintenance technologies, if so, in what context. Then, we explore perspectives from the manufacturing SMEs on added values, challenges, opportunities, advantages, and disadvantages of smart maintenance technologies. However, as none of the case companies had implemented any Smart Maintenance Technologies, only implementation challenges could be investigated.

    A Testbed for Smart Maintenance TechnologiesManuscript (preprint) (Other academic)
    Abstract [en]

    Industry 4.0 presents nine technologies including Industrial Internet of Things (IIoT), Big Data and Analytics, Augmented Reality (AR), etc. Some of the technologies play an important role in the development of smart maintenance technologies. Previous research presents several technologies for smart maintenance. However, one problem is that the manufacturing industry still finds it challenging to implement smart maintenance technologies in a value-adding way. Open questionnaires and interviews have been used to collect information about the current needs of the manufacturing industry. Both the empirical findings of this paper, as well as previous research, show that knowledge is the most common challenge when implementing new technologies. Therefore, in this paper, we develop and present a testbed for how to approach smart maintenance technologies and to share technical knowledge to the manufacturing industry.

    A Conceptual Implementation Process for Smart Maintenance TechnologiesManuscript (preprint) (Other academic)
    Abstract [en]

    Industry 4.0 is usually presented as usage of technologies. Some of these play an important role in the development of smart maintenance technologies. How-ever, although the subject of smart maintenance has been discussed for more than ten years, the manufacturing industry still finds it challenging to implement smart maintenance technologies to add benefits to maintenance organizations in line with company’s goals. This study presents a conceptual process for implementing smart maintenance technologies, challenges and enablers to consider when implementing, and benefits. This article is based on an analysis of empirical findings from seven large manufacturing companies in Sweden, previous maintenance research, and au-thors’ three previous smart maintenance research articles. In the first article, the authors explored perspectives on smart maintenance technologies from eleven large companies within the manufacturing industry, while in the second one, perspectives on smart maintenance technologies from fifteen manufacturing Small and medium-sized enterprises (SMEs) were presented. In the third and final one, the authors de-veloped and presented a testbed for smart maintenance technologies.

    Machine criticality assessment for productivity improvement Smart maintenance decision support2019In: International Journal of Productivity and Performance Management, ISSN 1741-0401, E-ISSN 1758-6658, Vol. 68, no 5, p. 858-878Article in journal (Refereed)
    Abstract [en]

    Purpose The purpose of this paper is to increase productivity through smart maintenance planning by including productivity as one of the objectives of the maintenance organization. Therefore, the goals of the paper are to investigate existing machine criticality assessment and identify components of the criticality assessment tool to increase productivity. Design/methodology/approach An embedded multiple case study research design was adopted in this paper. Six different cases were chosen from six different production sites operated by three multi-national manufacturing companies. Data collection was carried out in the form of interviews, focus groups and archival records. More than one source of data was collected in each of the cases. The cases included different production layouts such as machining, assembly and foundry, which ensured data variety. Findings The main finding of the paper is a deeper understanding of how manufacturing companies assess machine criticality and plan maintenance activities. The empirical findings showed that there is a lack of trust regarding existing criticality assessment tools. As a result, necessary changes within the maintenance organizations in order to increase productivity were identified. These are technological advancements, i.e. a dynamic and data-driven approach and organizational changes, i.e. approaching with a systems perspective when performing maintenance prioritization. Originality/value Machine criticality assessment studies are rare, especially empirical research. The originality of this paper lies in the empirical research conducted on smart maintenance planning for productivity improvement. In addition, identifying the components for machine criticality assessment is equally important for research and industries to efficient planning of maintenance activities.

    Collaborating with society (businesses, industry and municipalities) is a common practice for many universities today. To support such collaborations, there is a need to share and evaluate these practices. This research explores the use of creative and visual methods from Participatory Design to support reflective practice in university-society collaborations. The paper describes an exploratory workshop consisting of an abstract collage-making exercise and a list of questions. The purpose of this workshop is to see how the visual exercise could support discussions about university- society collaborations and to develop future studies. The results from the workshop show that using abstract collages generated multiple interpretations and metaphors about the visualized collaborations. The collage-making exercise prompted discussions about the interrelationship between collaboration, innovation processes and knowledge creation. It also stimulated playful interactions between participants. Moreover, the workshop participants gave valuable feedback on how to develop materials and questions to discuss university- society collaborations.

    Relational Sensitivity and Participatory Practice: Exploring Poise and Punctuation through an Empirical Study2022In: ACM International Conference Proceeding Series, Association for Computing Machinery , 2022, p. 186-190Conference paper (Refereed)
    Abstract [en]

    Poise-self-awareness of how one is and acts, and punctuation-attunement to relational dynamics, describe integral relational sensitivities for practitioners in Participatory Design (PD). These concepts describe important personal and embodied "practices of readiness"for participating in contingent and relational processes of designing with others. However, more attention on these "practices of readiness"is required in design research and design training to better comprehend and develop relevant relational sensitivity and competences. Through an empirical study, this paper explores what relational sensitivity i.e., poise and punctuation, could be in a participatory practice and what it can do for the process. The paper also explores ways in which relational sensitivity could be nurtured through participatory practices. This research contributes to PD literature by connecting concepts related to relational sensitivity with an empirical study, elaborating on the role of relational sensitivity in PD practice.

    Resource Simulation of Machining Processes and Operator Optimization: A Generic Model2022Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Purpose – The purpose is to present a Generic Model that considers the machining process's resource simulation into account as well as the operator variables. The operator variables are associated with the operations they carry out, the time required, and the ideal number of operators. This Generic Model will serve as a framework for future initiatives for industry and academia, by including resource simulation for machining operations.

    Design/Methodology/Approach - The simulation model addresses the optimal resource allocation to support efficient machine utilization. The resource in this simulation model is composed of human operators, working across several machining operations of similar specifications, with all of the machines arranged in parallel. The resulting simulation model presented in this thesis is generic in its organization.

    Findings - The developed Generic Model incorporates material-flow and logistics, tool-ware and machine failure, product-tool interdependence, and other related factors pertaining to the operator task allocation and the number of operators. Further, the optimization of process resources has been presented through results obtained pertaining to machine utilization, productivity and operator distance travelled.

    Research implications - Several industries are working towards overcoming the challenges pertaining to the resource allocation in the manufacturing process and the requirement for optimizing. As a result, simulation provides a less expensive option for making resource allocation decisions and testing the chosen options. The presented Generic Model will serve as a framework for future initiatives including resource simulation and allocation for machining operations and operators.

    Originality/Value- The model presented in this thesis, will therefore allow production planners and managers to allocate the necessary resources and observe the outcomes before they are implemented on the shop floor. The Generic Model adds value by allowing for future adjustments in model resources and parameters based on system requirements.

    Barriers to Value Specification when Carrying out Digitalization Projects2021In: Technology Innovation Management Review, E-ISSN 1927-0321, Vol. 11, no 5, p. 54-64Article in journal (Refereed)
    Abstract [en]

    If digitalization projects aim to effectively create value for a company, one precondition is having a shared view among company staff and project members of what the "desirable" value is. However, it has been shown that few companies fully understand the value that digitalization projects can create for them, while many companies still launch digitalization projects without this understanding. This contributes to the current "alarmingly" low success rate for digitalization projects. Development of effective methods to specify the desired values of digitalization projects is thus important. One step in developing improved specification methods is to ask what the possible barriers are to improving current value specification practices. The purpose of the current study is to address this. We analyzed several digitalization projects regarding how specifications of desired project value were carried out, finding that very limited resources are spent on specifying desired values in digitalization projects, and that this limits project success. Likewise, there are several barriers to increasing resources for specifying desired values. Our findings contribute to understanding the development of value specification methods that aim to overcome these barriers and thus could help improve the success rate of digitalization projects.

    How to deal with differing views of resource efficiency when carrying out digitalization projects2020In: Advances in Transdisciplinary Engineering, Volume 13, 2020, p. 71-82Conference paper (Refereed)
    Abstract [en]

    Having project goals that are shared among project members are preconditions for resource efficient as well effective projects and operations. However, specifying and communicating project goals require an ability to identify goals that are indeed commonly shared. Rapid technological developments may require digitalization projects that lead to large portions of existing company staff being redundant, making it possible to assume that the quest of finding a commonly shared view of what is ‘resource-efficient’ will be increasingly challenging. Development of methods to specify project goals that are incentivizing for all project members and staff can hence be assumed to be important. One step in developing improved specification methods is to ask how the process to specify desired value from digitalization projects handles possible disagreements of what is ‘desired value’. The purpose of this study was to answer this question. We analyzed several digitalization projects, and how specifications of desired project results impacted project outcomes. We found that potential disagreements regarding desirable project outcomes generally are avoided by avoiding specification of what a desirable resource efficiency outcome is, and how actual project outcomes should be measured. However, we also found that this practice also led to unsatisfying project outcomes regarding resource-efficiency improvements, and that improved methods to specify desired value from digitalization projects should be developed. Our findings support earlier findings that the general failure rate of digitalization projects is high, often due to insufficient specification of desired projects outcomes before the projects are initiated. Our findings contribute to the understanding that despite this, there are also perceived benefits of spending limited resources on specification of desired outcomes. If attempts to improve the success rate of digitalization projects by improving specifications of desired project outcomes is to succeed, these perceived benefits must be considered

    Safety Assessment Strategy for Collaborative Robot Installations2017In: Robots Operating in Hazardous Environments / [ed] Hüseyin Canbolat, INTECH, 2017, p. 111-129Chapter in book (Other academic)
    Abstract [en]

    Industrial resource efficiency can be improved if the safety barrier between humans and robots is removed, as this enables operators and robots to work side by side or in direct collaboration to solve a task, usually referred to as a collaborative robot installation. Even though technology development makes the barrier removal ever more feasible from a safety perspective, this still produces a possible hazardous working environment, and safety assessment strategies are crucial. A wide area of knowledge is required to assess all fields that can help ensure safe human-machine interaction. Here the focus is primarily on providing a description of the key fields identified, including how operators psychologically accept working with robots, and providing a cursory description of the research front for each individual field. In addition to covering a large number of parameters, the assessment strategy also needs to be cost-effective. A significant part of all parameters that can be considered when attempting to produce optimized and cost-effective collaborative robot installations will also have a direct impact on operator safety. Hence, assessments for safety, and assessments for cost-effectiveness, cannot be separated, and are treated as two objectives that need to be viewed in sync

    Competitive Internal Logistics Systems through Automation2011Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The growing demand for products and services puts great pressure on logistics performance and enhances the role that logistics plays in determining a company’s competitiveness.

    This research focuses on internal logistics systems, which includes all logistics activities and processes within the physical limits of an isolated company. Internal logistics is vital for the overall function of many companies. However, despite its importance, this part of logistics has traditionally not been viewed or developed in a strategic way. Since internal logistics activities are often characterized by a high degree of manual handling and hence strongly affect the cost of operations, there is a large incentive for improvements in this area.  

    One possible way to improve an internal logistics system is with the help of automation. In many areas, automation is a well-known means to increase productivity and cut costs, thus improving competitiveness. However, automation is not commonly used within internal logistics activities, and there is a lack of knowledge and research within this new application area. The main objective of this research, therefore, is to contribute to an increased understanding of how automation can be used to develop competitive internal logistics systems.

    Four empirical studies have been performed to investigate how companies perceive and work with their internal logistics systems, specifically in terms of improvements using automation. The empirical studies also aimed at identifying and describing how the studied companies could benefit from automation within internal logistics activities.

    From the studies, the importance of assessing and being aware of the current state of logistics performance was discovered as a basic requirement that needs to be fulfilled before conducting improvement work. Further, one of the main overall conclusions from this research is the need for a logistics strategy that includes goals and plans for the operation and development of an internal logistics system. As a result of the research, a structure and procedure for the development of a logistics strategy and a framework for conducting an improvement process in internal logistics using automation were developed.

    Resource Efficiency in Internal Logistics: a Survey on Objectives and Performance2011In: Proceedings of the 4th International Swedish Production Symposium, 3rd-5th of May, Lund, Sweden / [ed] Jan-Eric Ståhl, 2011, p. 303-311Conference paper (Refereed)
    Abstract [en]

    A growing need for flexible supply chains and low cost make logistics more complex and critical for competition. Internal logistics is a crucial function in manufacturing industries but despite its potential as a competitive strategy it has not been in focus when discussing performance and efficiency. The aim of this paper is to show and discuss how manufacturing companies work with, perceive, and develop their internal logistic system. The paper is based on the results from a survey study of Swedish manufacturing companies, intended to give an outlook of the current situation and views. The results show that system performances and information aspects together with a balanced flow and committed staff are the most important success factors for a well functioning internal logistic system. The most important performance criteria are delivery precision and dependability together with customer service and quality degree. Competence and manpower are considered the most critical resources, but desired and ongoing improvement work rarely relate to these areas. Many lack extensive performance measurement systems for logistics, risking sub optimization. Most also lack a vision and strategy with their internal logistic system and many do not have anyone who is strategically responsible for operating and developing it.

    Förändringar inom materialförsörjning till följd av globala inköp: En fallstudie på ABB Robotics, Västerås2007Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [sv]

    Dagens hårda konkurrenssituation har lett till att många svenska företag i jakten på att sänka sina kostnader söker nya leverantörer i lågkostnadsländer. Den globala handeln har ökat markant de senaste åren men utredningar gällande hur verksamheters materialförsörjning påverkas av långväga inköp har ej hunnit med i samma utsträckning.

    ABB Robotics som i sin verksamhet i Västerås utvecklar och tillverkar industrirobotsystem är ett av de företag som satsar på global handel. Som ett led i detta står verksamheten under andra halvåret av 2007 inför stora förändringar då en del av företagets leverantörsbas skall bytas från europeiska till asiatiska tillverkare. Detta examensarbete syftar till att kartlägga hur ABB Robotics materialförsörjning kommer att påverkas av bytet av leverantörsbas. Det övergripande målet är att utreda och ta fram en modell för hur verksamheter ur ett materialförsörjningsperspektiv påverkas av global handel.

    Två Microsoft Excel-baserade simuleringsverktyg har tagits fram under detta examensarbete för att möjliggöra kartläggning av leverantörsbytenas inverkan hos ABB Robotics. Det ena av dessa verktyg beräknar hur säkerhetslagernivån kommer att förändras till följd av bytet av leverantörs-bas. Resultatet visar bl.a. på en markant genomsnittlig ökning med ca 700 % jämfört med dagsläget under de förutsättningar ABB Robotics angivit. Modellen är dock konstruerad så att vissa parametrar som täckningstid, servicegrad etc. enkelt kan ställas om för att undersöka dess inverkan på säkerhetslagernivån.

    Det andra verktyget simulerar inleveransmönstret under utfasningen av de nuvarande leverantörerna respektive upprampningen av den nya leverantörsbasen. Resultatet av verktyget ger en bra bild av hur de inkommande lagervolymerna kommer att variera under leverantörsbytena, när topparna kommer att inträffa samt hur stora de kan förväntas bli.

    I examensarbetet har ABB Robotics arbetssätt och planer inför den stundande globala handeln utvärderats och analyserats. De parametrar inom materialförsörjningen som påverkas av de globala inköpen har kartlagts liksom dess förändringar. En lista på rekommendationer från författarna gällande hur ABB Robotics bör agera vid det stundande bytet av leverantörsbas har också tagits fram.

    Författarna har även som resultat av detta examensarbete arbetat fram tre generella modeller för att påvisa hur verksamheter ur ett materialförsörjningsperspektiv påverkas av globala inköp. Två av modellerna har fokuserat på förändringar hos mätbara respektive icke mätbara parametrar och dess inbördes förhållanden medan den tredje modellen påvisar korrelationer mellan två varierande parametrar.

    Managing automation development projects: A comparison of industrial needs and existing theoretical suppor2013In: Advances in Sustainable and Competitive Manufacturing Systems: 23rd International Conference on Flexible Automation & Intelligent Manufacturing, Springer , 2013, p. 761-774Conference paper (Refereed)
    Abstract [en]

    The use of automation can increase competitiveness but does not guarantee advantageous results. The right choice of technology and correct implementation and use is the key to a successful outcome. This in turn puts great demands on how automation development projects are managed. The aim of this paper is to make a comparison between industrial needs and existing theoretical support associated with managing automation development projects. Through a multiple case study, challenges and success factors related to managing automation projects have been identified. The empirical findings are compared with automation development support found in literature. The results from the empirical study indicate the need for improved process models and clear strategy connected to automation development. The importance of an overall view and planning during automation projects is highlighted as a success factor while difficulties in collaborating with third parties is identified as existing challenges. It is concluded that the support in literature deals with many of the identified challenges and success factors and offers some support for specific parts of the automation development project. There is however still need for an overall framework connecting existing theoretical support, and suggesting how strategy can be connected to the process of developing automation.

    Lean Automationsutveckling - Handbok2016Report (Other academic)
    Abstract [en]

    Trender mot mer automatiserad produktion och allt snabbare förändringstakt av produktionssystem ställer krav på snabba, effektiva och verksamhetsanpassade utvecklingsprocesser av automationslösningar. Denna handbok beskriver centrala delar i en automationsstrategi, som stöd för utveckling av automationslösningar till produktionssystem. Den är relevant för alla typer av tillverkande verksamheter och leverantörer som vill effektivisera anskaffandet och införandet av ny automationsteknik. Handboken beskriver en automationsstrategi uppdelad i fyra huvudområden: Del 1 – Ekonomi Del 2 – Organisation Del 3 – Process Del 4 – Teknik Stort fokus ligger på att engagera olika kompetenser och aktörer, liksom att betrakta automationsstrategin som en del av en helhet tillsammans med övriga delar i och utanför verksamheten. Automationsstrategin lyfter vilka faktorer inom de olika huvudområdena som påverkar vid utveckling av automationslösningar. Den gör det möjligt att analysera vilken affärsmodell som passar verksamhetens förutsättningar bäst och vilka organisatoriska strukturer som är viktiga för verksamhetens automationskompetens. Den innehåller också en stegmall för effektiv anskaffning av automationsutrustning och tre viktiga kategorier av teknik som kan stötta utvecklingsprocessen. Handboken har tagits fram i projektet lean automationsutveckling, eller LEAD, som har finansierats av Vinnovas program FFI Hållbar produktion under 2013-2015. Grundidén var att underlätta både planering, utveckling och anskaffning av automationslösningar genom att förse de utvecklingsprocesser som idag är etablerade med verktyg från lean produktutveckling. På så vis säkerställs att verksamheter kan dra nytta av ny automationsteknik med så effektivt utnyttjande av resurser, hög hållbarhet och hög lönsamhet som möjligt.

    NEW ELECTRICAL CONTACT MATERIAL AND DEPOSITION PROCESS FOR CERAMIC HEATING ELEMENTS2021Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The thesis focuses on an estimation of investment potential in alternative equipment for the deposition of a thin film on the ends of Kanthal Super heating elements. The film serves as an electrical contact when the elements are installed in an industrial furnace for heat generation and control. Currently, an arc spraying process involving aluminium film deposition is used. Aluminium in the form of powder is explosive and reactive. Therefore, the arc spraying equip­ment is impos­sible to integrate into the heating element production line. Thus, various conduc­tive material groups were investigated in terms of electrical conductivity, melting point, oxida­tion resistance and cost as an alternative to aluminium. The result of the material study is four deposition ma­terial options including aluminium- and copper-based alloys to be studied further with alterna­tive deposition methods. The deposition method study allowed selecting un­balanced DC mag­netron sputtering with rotating substrate holders to perform deposition tests with. Pure aluminium was selected as deposition material as alloys may sputter non-uniformly, and copper, in particular, is not compatible with the Kanthal Super material chemically.

     

    Further investigation based on the recommended magnetron sputtering machine proved that the machine improves product quality by coating film lengths within the standard range of 25-100 mm to fit electrical connection braids. Minimum sputtered film thicknesses are 10 times lower the maximum expected value, which points at lower film porosity. Lastly, improved sputtered film adhesion compared to arc sprayed films is achieved through sig­nifi­cantly longer heating element pre-cleaning with RF plasma in high vacuum. Thus, heating ele­ments are expected to be more durable in operation. Furthermore, it is undefined whether the sputtering machine improves deposition process efficiency. The number of machines, the amount of coated element sizes in one machine and personnel involved, the number of manual operations and the coating capacity per working day are comparable with the set values. How­ever, coating capacity is estimated based on the assumption that the minimum sputtered thick­ness is enough to provide the same electrical contact as the arc sprayed thickness. The number of sputtering process parameters to control is approximately twice as high compared to the set value based on the arc spraying process. This proves the unnecessary complexity of the sputtering process. On the other hand, sputtering contributes to increased safety of the deposi­tion process by eliminating the number of hazardous aluminium particles in the air due to process isolation in a high vacuum. The noise levels are kept within the officially set limit of 80 dB at a workplace. From the cost efficiency perspective, the sputtering machine is within the set limit of maximum 110 % when it comes to pure economical investment while yearly operating costs were found to be 5 % higher than the set limit. Thus, magnetron sput­tering is a suitable method to perform metallization of electrical contacts on Kanthal Super heating ele­ments. It can be recommended as an alternative deposition method if physical tests are per­formed to confirm the film thickness assumptions.

    Exploring the Integration of Additive Manufacturing: Lessons Learned and Success Factors of Use Cases2023In: Industrializing Additive Manufacturing. AMPA 2023 / [ed] Klahn, C., Meboldt, M., Ferchow, J., 2023, p. 423-439Conference paper (Refereed)
    Abstract [en]

    The purpose of this paper is to present propositions for facilitating the integration of additive manufacturing (AM) for manufacturing companies in the heavy vehicle sectors based on identified success factors and lessons learned in use cases with different operational purposes. A case study was conducted that identified 42 retrospective use cases from three main sources highlighting seven different use case types with contributions from seven sectors representing 14 countries on four continents. Six success factors (technology infrastructure, relative advantage, organizational readiness, competitive pressure, expectations of market trends, and trading partner) and 20 lessons learned sorted into five dimensions (additive thinking, management aspects, practice makes perfect, AM acceptance, and AM experts) were identified in the use cases based on the analysis. Three propositions covering the three stages of integration were derived based on the identified success factors and lessons learned. These propositions should provide guidance on what managers need to be prepared for when integrating AM step-by-step. Integrating AM is no simple feat, and the propositions only scratch the surface since the complexity of AM runs deep both technically and managerially. Future research should investigate in-depth operational capabilities and, if applicable, dynamic capabilities to further enhance facilitating the integration of AM step-by-step.

    Integration of Additive Manufacturing in an Industrial Setting: The Impact on Operational Capabilities2023In: Advances in Production Management Systems. Production Management Systems for Responsible Manufacturing, Service, and Logistics Futures / [ed] Alfnes, E., Romsdal, A., Strandhagen, J.O., von Cieminski, G., Romero, D, 2023, p. 590-604Conference paper (Refereed)
    Abstract [en]

    The purpose of this paper is to explore changes in operational capabilities and their impact when integrating additive manufacturing into a traditional manufacturing company. This was exemplified based on a sub-system component (gears and shafts in a gearbox) for automotive applications that are developed and manufactured at a manufacturing company in the commercial vehicle sector. The research was set up based on a case study consisting of semi-structured interviews, informal meetings, observations, company documents, reports, presentations, and field notes. The literature and findings from empirical data converged into 57 themes of operational capabilities that were categorized into six aggregated dimensions. The results suggest two emerging dimensions, namely stakeholders and strategy, building upon an existing theoretical framework. Integrating AM into traditional industrial settings requires several changes in operational capabilities. It is essential to consider the following priorities, 1) gain understanding and knowledge in design for AM, 2) build robust AM infrastructure as an integral part of existing infrastructure, 3) evaluate AM process changes in product development and production, 4) establish an internal AM team with at least one person working full time with AM, 5) establish collaborations with suitable AM research partners, and 6) conduct AM management and evaluate the business impact not only short-term but also long-term. Future research should investigate operational capabilities from other use cases, dynamic capabilities in the same or similar contexts, and transform the required operational capabilities into guidelines and best practices for managers and other decision-makers in the manufacturing industry.

    Coping with Variability in Automotive Product line Architectures Using Real Options2007Conference paper (Refereed)
    Abstract [en]

    The automotive customers demand new functionality with every new product release and the time-to-market is

    constantly shortened. The automotive embedded systems are characterized by being mechatronic system which adds

    complexity. The systems are often resource constrained and trade-offs between the system behavior and the resources required is of great importance. The decisions are usually based on many factors that pull in different directions such as maintenance, portability, usability etc. The complex system and the many uncertain factors create a need for support in the design process. In this paper the use of Real Options is evaluated on a hypothetic but realistic case taken from the automotive industry. The case show how real option valuation provides additional guidance when making system design decisions. Real Options provide the opportunity to analyze the cost of designing for future growth of an platform, based on the estimated value of the future functionality. The value of a flexible design can thereby be quantified making the trade-off between short and long term solution more accurate.

    In many industries, complex embedded product lines are designed. In theory, this follows a structured and well-organized process, where a set of given requirements is transformed step by step into an optimal product. However, in reality the complexity of the products and markets often lead to much less stringent ways of working. Let us consider a fictional, but not atypical, scenario.

    Standardization of layout routing using product development and process optimization: A concept study conducted at Quintus Technologies AB: Master thesis work 30 credits, Advanced level2023Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Moving from a project-based to a product-based organization comes with its own challenges, which goes for most organizations when one business model is changed to another. These changes lead to uncertainties in the work for the engineers, where lead time increases and time for the projects. This master thesis aimed to evaluate the uncertainties' characteristics and set standardizations in the work process to optimize the workflow and reduce engineering hours spent per project. The goals set for this thesis formulated three research questions:

    RQ1: What characterizes a reduction of engineering uncertainties through product-based structures? 

    RQ2: How can current layout modules be converted into standardized product-based structures?

    RQ3: How can standardized layout modules ensure the reduction of engineering uncertainties throughout the product-development process?

    By examining a case company’s journey through this transition through a quantitative methodology, three cases that each follow the product development process were conducted to answer the three research questions. The results for this thesis indicated that the implementation of standards reduced lead time and overall inconsistency, thus contributing to a more efficient modelling environment for the engineers and consistent implementation of an adaptable model for PDM integration. Implementing a design for assembly methodology proved to be a successful choice in reducing the assembly time for the engineers. An evaluation of the results indicates that only 34% of the engineering hours currently spent on conducting customer-based layout routings for the case company would be necessary when utilizing the standardized modules.

    Developing collaborative power in working life: linking American pragmatism and action research2013In: American Pragmatism and Organisation: Issues and Controversies / [ed] Kelemen, M. & Rumens, N, Gower Publishing Ltd., 2013, p. 205-222Chapter in book (Other academic)
    Abstract [en]

    This chapter argues that American pragmatism can inspire and support an important shift in prevailing social science discourses on power towards non-coercive, collaborative understandings of power consistent with a participatory democratic politics and way of life. It draws out an understanding of non-coercive, collaborative power from the works of Dewey and Follett, and illustrates its relevance for the analysis of power in the domain of action research. Collaborative power is here understood as power in the making’. Its chief merit is ensuring, first and foremost, cooperation between parties. The significance of collaborative power is more broadly applicable than the local communities in which the concept was originally developed. The concepts of circular response and integration of interest are useful in analysing collaborative power at the micro, meso and macro levels of society. Powerful people are, by virtue of their proprietary rights, able to change and reduce the effects of collaborative power.

    Value Stream Mapping – Alfa Laval: Kartläggning av produktion- och informationsflödet2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Med utgångspunkten att ständigt förbättras och öka konkurrenskraften arbetar Alfa Laval mot Leanprinciper. Vad som dock är ett problemområde är att se över fabriken ur ett helhetsperspektiv, närfabriken är uppdelad i många avdelningar. Lösningen till detta problem är att via olika metoder ellerverktyg kunna fastställa svaren på problemen.Denna examensrapport redogör för hur metoder inom Lean produktion kan vara lösningen förproblemområdet. Forskningen är huvudsakligen byggd på en bred värdeflödesanalys som syftar till attfånga in ett företags alla aspekter ur ett helhetsperspektiv, med syftet att minska risker försuboptimering och istället optimera produktionen som helhet.För att se gränssnitt mellan informationsflödet har i denna forskning metoden swimlane utgjort enkartläggning över ett företags hela kontorsavdelning, planerings och inköps avdelningar.Resultatet av denna forskning visar att värdeflödesanals är en bra metod för att kunna identifieraslöserier, ojämnheter i produktion, brister vid tillverkningen och flaskhalsar. För att sammankopplaolika avdelningar av ett företags informationsflöde, visas i resultaten att swimlane är en bra metod försyftet.

    INFORMATION FLOW ANALYSIS ENABLING THE INTRODUCTION OF ADDITIVE MANUFACTURING FOR PRODUCTION TOOLS-INSIGHTS FROM AN INDUSTRIAL CASE2023In: Proceedings of the Design Society, vol. 3, Cambridge University Press , 2023, p. 2315-2324Conference paper (Refereed)
    Abstract [en]

    Additive Manufacturing (AM) has traditionally been used for prototyping of products, however, in the last few decades, it has seen a rising growth in the manufacture of final products. The addition of AM as a manufacturing method in the portfolio of a company's production capabilities increases the complexity of decision-making. This is because the decisions are often not based on the same criteria and constraints, as related to conventional manufacturing processes. In this paper, we investigate this challenge by studying how AM affects the current workflow and the associated information flow for a design-make process in a Swedish manufacturer before and after the integration of AM. In this paper, it is argued that apart from an understanding of how to design for AM, it is equally important to consider how introducing AM alters the existing information flow and how to benefit from information available in various design-make process steps to facilitate decision making process. The result clarifies that the current process relies largely on tacit and experiences-based knowledge, whereas to take advantage of AM, more precision is required to capture and process the available information.

    Underhållets Roll Inom Hållbara Produktionssystem2024Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study focuses on the impact of maintenance on sustainable production systems. Sustainability has grown in importance and become a central topic globally. Companies worldwide are working to streamline their production systems while striving to achieve sustainability goals. Maintenance of production facilities is a critical factor in reaching these goals, and various maintenance strategies play a key role in ensuring productivity, sustainability, and reliability in production systems.

    Although previous research has addressed both maintenance and sustainability, there is still a lack of comprehensive understanding and knowledge about the relationship between these areas. Therefore, the purpose of this work is to analyze and understand how different maintenance strategies within companies affect and contribute to sustainable production systems. By exploring how these strategies can promote environmentally friendly and economically sustainable production methods, we gain deeper insight into how companies can balance sustainability goals with performance in their operations.

    The research questions formulated for this work are as follows: How is a production system affected by maintenance? and What role do maintenance strategies play in promoting a transition to more sustainable production systems? 

    The research utilized a deductive method with a thorough literature review based on previous research and scientific articles. A qualitative method was also used for empirical data collection through a survey distributed to companies.

    By integrating sustainability aspects into maintenance work, companies can minimize resource use, emissions, and waste while optimizing the efficiency, reliability, and lifespan of their equipment. This enables a transition to more sustainable production methods and results in both economic and environmental benefits.

    Towards Logistics 5.0: An Approach for Selecting and Integrating Industrial Internet of Things2024Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Every manufacturing discipline is evolving rapidly with the emergence of Industry 5.0, which is defined as the incorporation of advanced technologies to enhance sustainability, human imperative, and resilience. Logistic activities inside a manufacturing facility is not an exception for this evolution. Industrial internet of things (IIoT) as a primary enabler for the digital transformation provides the companies with great opportunities. In this context, firms need a guidance for harmonious integration of IIoT technologies into internal logistics. Existed theoretical knowledge has not addressed this issue explicitly. Therefore, the thesis is aimed at exploring the selection and integration of IIoT into internal logistics for a more smart, automated, and connected factory. The purpose of the thesis is achieved by a qualitative case study approach in a large multinational machinery manufacturing company. The study begins with a literature review constructing a theoretical framework to answer the research questions. then, semi structured interviews, document review and observations were employed as data collection methods. Three use cases: sensors for automatic replenishment, pick to light indicators for kitting and automated goods receiving are studied thoroughly for understanding the practical aspects. Thorough analysis of the collected data shows that the challenges being faced are technological, organizational, external, and human related. Also, critical factors which impact the integration of IIoT technologies and must be considered during the process are addressed through the analysis. Connecting these findings together, a roadmap has been created with a detailed explanation of actions to be taken in each step. To the existing theoretical knowledge, this thesis adds the knowledge of human and organizational factors and how to address them through developing a roadmap. Also, this knowledge will guide the companies to better prepare their workforce. Additionally, the roadmap helps the practitioners in strategic decision making and to develop further understanding for practical implementation. Offering insights into the challenges and critical factors this work can guide future research and development in smart logistics systems.

    Realization of Flexible and Reconfigurable Industrial Robot Automation2008Licentiate thesis, comprehensive summary (Other scientific)
    Abstract [en]

    Today’s global market and tough competition between companies requires the development of increasingly productive production systems. Companies, struggling to become more competitive, use different advanced manufacturing technologies, such as industrial robotics. They seek higher productivity, consistent quality, and the removal of ergonomically unsound manual workstations. However, according to the general trends in the manufacturing industry, there is a need to implement production solutions that are flexible enough to handle a business environment exposed to frequent changes in production operations and product designs. The objective of the research presented in this thesis is to analyse how to support the design and implementation of flexible and reconfigurable industrial robot automation.

    This research is based on three case studies, carried out over a four-year time period. The researcher/author has been a participant in the projects studied. The first case study aimed at developing a flexible robotic working cell, and succeeded. However, although the cell was flexible enough to handle a wide variety of components, there were limitations on how easy it was to reconfigure the cell, i.e. change the operations performed in the cell and the layout of the cell. The second case study investigated how to design robotic working cells so that the cell is easy to reconfigure when there is a need to implement changes. Finally, the third case study focused on software support, with the main focus on enabling the user to rapidly introduce changes into a robotic working cell.

    As a result of the case studies, enablers for how to realize flexible and reconfigurable robotic working cells have been identified. In addition, the need for software support has been investigated, and a prototype of a supportive software tool has been developed.

    Intelligent Buffer Storage System: Enabling Fast and Flexible Assembling with Industrial Robots2006In: Journal of Intelligent & Fuzzy Systems, ISSN 1064-1246, Vol. 17, no 4, p. 367-376Article in journal (Refereed)
    Abstract [en]

    Production cells usually require a continuous supply of parts to be assembled. Elaborate feeding mechanisms or a system of prepared pallets on which the parts have exact positions are expensive and if a variation of the product is to be produced, the feeding mechanism or pallets must be modified. Such solutions do not provide sufficient flexibility and increase production costs. Today's requirements for smaller series and customized orders have higher requirements on production cells.

    In this paper we show how flexible and adaptive production can be achieved, using methods and techniques from artificial intelligence by introducing an "autonomous" production cell, integrating and managing its own local buffer storage. The production cell is able to produce a number of variants of the product with no time delay between different configurations. The storage system, designated "Floating Storage", handles the local buffer storage and guides the industrial robots to use available floor-space as storage. The system also orders parts from the main storage as the buffer storage approaches depletion. The parts arrive to the cell in standard containers and a commercially available vision system is used to locate the material. The prototype has been introduced in an assembly line at ABB.

    Robotics for SME´s – Investigating a Mobile, Flexible, and Reconfigurable Robot Solution2008In: 39th International Symposium on Robotics, ISR 2008, 2008, p. 56-61Conference paper (Refereed)
    Abstract [en]

    Today’s  business  environment  is  dominated  by  change and  uncertainty,  and  success  within  manufacturing  is becoming  more  and  more  difficult  to  sustain.  Also,  many European  manufacturing  companies  experience  low availability  of  human  resources  and  recruitment  problems. One way to handle this challenge and improve a company’s efficiency  could  be  to  invest  in  automation  and  industrial robotics.  However,  robot  automation  investments  are  in many  cases  still  too  difficult  and  too  technically  advanced especially  for small and medium sized enterprises. There  is need  for automated systems with an acceptable  investment, high  efficiency,  high  adaptability,  and with  such  flexibility that  it may produce  several different products  and  adapt  to future product variants without large additional investments. Thus,  the  concepts  of  flexibility  and  reconfigurability  are becoming  increasingly  important  within  manufacturing systems and robotic work stations. The objective of  this paper  is  to  investigate  the need  for flexible  and  reconfigurable  industrial  robot  systems  and  to present  some  possible  solutions  for  how  the  concept  of mobile  industrial  robotics  can  be  applied  within  industry, and  specifically  at  small  and  medium  sized  enterprises (SMEs). A conceptual solution for a mobile  industrial robot will be presented and evaluated in terms of applicability for a manufacturing SME. The  result  of  this  evaluation  is  that the concept of mobile  industrial robotics may be an enabler for  SMEs  to  overcome  the  barrier  to  invest  in  industrial robotics. However,  several  technical  developments  have  to be  accomplished  to  open  up  the  market  for  this  type  of solutions, and the common attitude of the SME would have to  be  changed  to  become  more  receptive  to  this  type  of highly  technological  solution,  i.e.  the perceived complexity of the highly complex system has to be low.

    INDUSTRIAL ROBOTICS IN THE LEAN ENTERPRISE – A CASE STUDY2008In: Advances in Manufacturing Technology - XXII: Proceedings of the Sixth International Conference on Manufacturing Research, 9-11 September, 2008, 2008, p. 171-180Conference paper (Refereed)
    Abstract [en]

    The  globalization  and  the  increasing  challenge  from  low-wage  competitors  highlight the need for European industries to enhance their ability to develop and manufacture products  competitively.  Meeting  customer  demands  requires  a  high  degree  of flexibility,  low-cost/low-volume  manufacturing  skills  and  an  ability  to  offer  short delivery times. In order to stay competitive, many manufacturing industries are trying to  implement  the  unique management  principles  and  practices  of  the Toyota Motor Corporation’s with many different names as e.g. “The Toyota Production System” or “Lean  production”.  One  question  and  debate  within  industry,  during  the transformation  towards  lean manufacturing  is whether  traditional robot automation fits  the principles and practices of  lean? This paper resents a case  study which has investigated  if  industrial  robot automation has a place  in a manufacturing  company pursuing the lean philosophy. The case study is based on one manufacturing company in  Sweden  that  is  currently  implementing  a  transformation  towards  a  lean-based production  system. The  case  study was performed  using  interviews  at  the  company, observation at the manufacturing plant, and workshops together with key-employees at the company. The results from the case study show that there is a need to align the company’s  present  robotic  equipment  and  machinery  towards  lean  principles.  The lean transformation within the company  is based on increased availability, controlled buffers, a more open  layout, and flow-based manufacturing with reduced batch sizes which all effect the equipment and machinery. In order for the robot automation to fit lean  principles  and  practices  there  is  a  need  for  development  of  robotized working cells  with  increased  availability,  reduced  set-up  times  by  improving  the  ability  for easily  reconfiguration,  and  improved  information  design  to  clearly  present  visual information and options to the operators.
