- Flexible human-robot industrial coproduction will be important in many small and middle-sized companies in the future. One of the major challenges in a flexible robot cell is how to transfer information between the human and the robot with help of existing and safety approved equipment. In this paper a case study will be presented where the first half focus on data transfer to the robot communicating the human's position and movements forcing the robot to respond to the triggers. The second half focuses on how to visualize information about the settings and assembly order to the human. The outcome was successful and flexible, efficient coproduction could be achieved but also a number of new challenges were found.

Konferensbidrag (refereegranskat)abstract
- In this paper, early work on how to implement flexible safety zones is presented. In the case study an industrial robot cell emulates the environment at a wall construction site, with a robot performing nailing routines. Tests are performed with humans entering the safety zones of a SafetyEye system. The zone violation is detected, and new warning zones initiated. The robot retracts but continues its work tasks with reduced speed and within a safe distance of the human operator. Interaction is achieved through simultaneous work on the same work piece and the warning zones can be initiated and adjusted in a flexible way.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In large organizations there are usually rather large groups of heterogeneous users with different tasks and different needs. Their requirements would most likely vary a lot when the system is designed to grant them access to different parts of the functions and applications In our earlier work we have tested the interface concept of Multi-Layered Design (MLD) on an operating system where each layer had a set of applications and tools. The users working with the system could get access to different applications depending on their level of experience or their different needs. The current paper presents how the MLD concept is taken one step further; implementing a layered design in a multi-user portal on a Citrix server. When a network solution is used, new available possibilities are given. The MLD approach can be combined with a role based access technique can the layered structure can be used in different ways for many different groups of users. In the study a MLD mushroom structure is employed where the user category decides the set of layers the different user groups can choose from while the individual user’s tasks and experience guide the choice of the specific layer. Thin clients are used to access the layer structure and five personas are made to represent the potential user groups. The results show that MLD can be used within a Citrix environment and that it is a viable alternative or complement for multi-user portals

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- En stor del av bilproduktionsprocessen är automatiserad. Ett fordons alla delar passerar flera olika stationer eller celler för att justeras och installeras, och robotar och människor har olika,vanligtvis separerade, uppgifter. Ett problem med denna typ av automatiserade produktion är den tid som det tar att vidta ändringar och frånvaron av medel hos den mänskliga operatören att kommunicera och interagera med roboten på ett flexibelt vis.

Multi-Layered Design and Game-Based Learning as a Pedagogical Concept : How to develop proper behavior in ARPA simulator training
- 2016
-
Konferensbidrag (refereegranskat)abstract
- To become a professional master mariner one has to develop many different skills and have an understanding of how to act in different situations on the bridge. Within the master mariner program at Chalmers University of Technology, Sweden, simulation technologies are used to evolve pertinent skills within the educational program. A challenge with using a full scale simulator from the outset of the program is to get the students to develop both professional competencies and internalize tacit knowledge in the navigation of a ship when the interface of the simulator itself is quite demanding. By using an adaptive Multi-Layered Design approach in combination with game based learning, this paper proposes how to guide the student through a more summative learning process. The main idea is to grant limited access to what the students can do with some functions, and gradually turn on more functionality in order to develop certain experienced behaviors to get them to understand the logical approach behind selections and to make them think through why and when they should do things.

Konferensbidrag (refereegranskat)abstract
- Software engineering has proposed the use of formal and industrial methods, models and tools within software industry for some time now. There are several good examples like the aircraft industry, branches of the military, the space shuttle development and the nuclear power plant industry that have come a long way with their software processes. However, there is still an ongoing dilemma of how to better introduce software processes within most regular production industry. In this paper we try to summaries our experiences of software processes and quality systems within the vehicle industry of northern Europe. A first investigating case study is conducted at a large software consulting company, focused on industrial software, and then we further investigate the software situation at one of the largest vehicle manufacturers in Scandinavia. We use a ten point list with adapted metrics to evaluate process quality and create a progress report of the work-flow and process implementation rate. Based on our results from the evaluation we also provide a first set of guidelines for how to level the differences in quality processes for hardware and software development.

Konferensbidrag (refereegranskat)abstract
- Digital technology is becoming ubiquitous and embedded as an integrated part of our daily lives, in which the digital and the physical worlds are increasingly interconnected and intertwined. While advanced technology can provide tremendous benefits and opportunities, it can also be very complex and challenging to understand, potentially leading to fear, suspicion, and distrust. This paper investigates a case of human-robot interaction in cooperative manufacturing, focusing on understanding how operators, managers and viewers feel about cooperating with industrial robots using potentially dangerous tools like nail guns. The aim of the study is to identify how human reactions to technology-induced change can be understood. The research question is: how can different trigger points of fear or distrust in technology be understood in the context of human-robot interaction? The findings reveal three key factors in overcoming fear, creating trust and encouraging interaction: knowledge, control, and self-preservation. The main contribution is illustrated through suggested guidelines for aspects that have to be practically considered when building this type of flexible robot cell for interacting with industrial robots in a real setting.

Co-constructing Expertise : Competence Development through Work-Integrated e-Learning in joint Industry-University Collaboration
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis is inter-disciplinary and proceed from the ongoing challenges of the increased digitalization, automation and robotization that impact the manufacturing industry's emergent need of high-qualified practitioners. Digitalization also challenges universities to open up to external collaboration and to design blended e-learning targeting industry knowledge needs. The studies take up on such challenges and explore inter-organizational collaborations and forms of knowledge construction to strengthen engineering competences integrated inwork in a way that enables manufacturing companies to remain effective and to be prepared for future industrial transformations. The objective is to explore how mutual construction of knowledge emerge through learning activities between multiple actors in a joint industry-university collaborative e-learning practice. The empirical setting is a new type of collaborative course concept developed within the project ProdEx. The project comprise a network of industries and one university in a longitudinal design and implementation process of blended and work-integrated e-learning. This initiative was explored with a collaborative action research approach integrated with five studies, from four perspectives, the industry managers, the practitioners, the research teachers and the course unit. Negotiated knotworking, from cultural-historical activity theory, became a central theoretical concept and a working tool to examine how managers, practitioners and research teachers together negotiated production technology knowledge content and e-learning design towards future workplace transformations. This concept was used to further understand how co-construction of knowledge was developing over time into a richer concept. The results contributes to a wider understanding of how co-construction of knowledge in an e-learning design practice was developing into stronger relations between actors and into more stable courses. Real learning cases and digital labs support theory-practical intertwining of mutual learning of active participation between practitioners and ix research teachers. Initial e-learning technology failures and pedagogical mistakes in the courses were easier to overcome, than issues concerning continuous company support for course participation. Matching industry competence needs with university research fields is continuously challenging. Practitioners' aiming for personal continuous competence development on university level created critical and high-qualitative performances and valuable engagement throughout the process of co-construction of knowledge. The knowledge co-construction became a two-way development, pushing research teachers to active involve and consider practitioners' industry experiences concerning learning content, pedagogical strategies and e-learning forms. While earlier research has discussed the problems of crossing boundaries between industry and university, overall findings show that industry and university actors are crossing boundaries when they mutually co-construct knowledge in an elearningpractice. Co-construction of knowledge entail mutual trust, sideways and interactive learning in a collaborative context. The main contribution suggested in the thesis is that co-constructing expertise entail three levels of activities among actors; to have insight into the purposes and practices of others (relational expertise), the capacity to transform the problems of a practice and together build common knowledge (distributed expertise), and finally the capacity of mutually co-construct knowledge acted upon in practice towards work-integrated transformations (co-constructing expertise).

Consideration of market demand volatility risks, when making manufacturing system investments
- 2016

-
Konferensbidrag (refereegranskat)abstract
- When investing in new manufacturing systems, many aspects must be taken into consideration to ensure a sustainable business. In respect to the financial aspect, both the one-off investment cost and the continuous operational cost must be analysed to ensure that the life-cycle cost perspective is appreciated. However, one detail in the cost analyses that is often overlooked is the composition of fixed and variable cost elements. These details are important to be able to better manage the risk of market demand volatility, and accordingly make appropriate investment decisions. This case study demonstrates that when there is a low risk for reduced market demand, investing in a manufacturing system with low variable cost is favourable. However, if there is a high risk for reduced market demand, the importance will instead be to have a low fixed cost, as this will be the dominant cost factor. (C) 2016 The Authors.

Tidskriftsartikel (refereegranskat)abstract
- When designing and developing manufacturing systems, many aspects need to be considered. Typically, the manufacturing design objectives are specified to achieve certain operational requirements around quality, capacity, cost etc. They are also specified withthe intention to ensure efficient processes related to manufacturing, such as maintenance, logistics, not to mention the main process of manufacturing the actual part. This study proposes that a wider company perspective should be considered during manufacturing system design, to achieve a greater business value. The manufacturing system should be designed to create value to other core business processes, such as product development, marketing, sales and services. This paper also presents examples on value perspectives to consider and how this approach can be implemented.

Tidskriftsartikel (refereegranskat)abstract
- In the investment selection process during the design of new manufacturing systems, both the technical attributes and the expected financial performance need to be evaluated. To manage the financial risks with market volatility, it is important to understand the composition of fixed and variable cost factors in relation to the expected volume interval. The support model developed in this paper will in a simple and intuitive way visualise the effect on production cost due to changes in market demands. It can also be used to evaluate the volume sensitivity of existing manufacturing systems, even compare systems making different products.

Tidskriftsartikel (refereegranskat)abstract
- PurposeThis paper presents findings from a qualitative study of healthcare professionals’ practice, where learning is taking place when a digital artefact is implemented for identification of patients’ cognitive impairment. The use of digital artefacts is increasing in various workplaces, to include professionals in healthcare. This paper aims to explore the following research question: How is the professional learning unfolding in patient-based work when a digital artefact transforms the practice?Design/methodology/approachVarious data collection methods are used for this study, consisting of dialogue meetings, interviews and a reference-group meeting. Thematic analysis is used to inductively bring forth the themes of the collected data.FindingsProfessionals’ knowledge and experience are of vital importance in learning and changing work practices. Together with their ability to reflect on changes, their knowledge and experience constitute the prefiguration when the introduction of a digital application brings about indeterminacy in the work practice.Originality/valueThis paper makes a contribution to practice-based research as it consolidates previous research and identifies professionals knowledge and learning in a healthcare context. This can be used to further explore and advance the field, as well as to establish the evidence-based importance of transforming practices based on implementation of digital artefacts.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Since the beginning of time, humans have been fascinated and intrigued by new technology, but also frightened of its implications. In the 1980s, Chao and Kozlowski [1] studied the introduction of fully automated lines in mass-production industry, and identified different fear factors influencing the workers willingness to change their work process. This study is more than 30 years old, however their insights are still relevant and tends to become even more important with the introduction of complex technology like ubiquitous and embedded systems, AI, big-data, and collaborative technology [2]. This rapid and ongoing digital transformation will have fundamental implications for the way we organize work and for how we design work processes and production system, not only in the manufacturing industry but in all parts of the working life, including the healthcare sector, schools, service, logistics and society ingeneral. It is also likely to influence and challenge roles and relationships and require new constellations of expertise and professional domains [3, 4]. In this paper, we compare experiences from practice in the manufacturing industry and health care domains and try to identify how fear of technology-induced change can be turned into trust, through knowledge exchange, competence development, and inclusive project management. In line with [1] we have identified four main fear factors related to digital transformation, in both the industrial context and the healthcare organization:Fear of losing one's jobFear of new, unfamiliar tasks and expectationsFear of change in general but in group relations and roles in specificFear of the actual technologyThe number of manual jobs is decreasing; contrasting feelings of responsibility and loss of control are common when adapting to new conditions in a new work environment; new workplace technology maychange traditional practice and there by lower the autonomy and power of the professions; and new machines could cause physical injury or, with a digital system, lead to security threats, loss of data, orthe sense of intrusiveness [2, 3]. Our studies found, some what contra intuitive, that workers with no or limited knowledge about the technology in use experience less fear. While workers with experience of the technology they interact with, tend to have more fear, and require a larger sense of control to be able to trust the system. We suggest that each of these fears can be addressed and linked to work integrated learning strategies to turn the fear of technology into digital trust by giving the worker tools for better control. Through collaborative competence development and inclusive workplace learning, different solutions can be explored to create conditions for trust. REFERENCES[1] G. T. Chao, and S. W.
