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).

E-learning Readiness and Absorptive Capacity in the Manufacturing Industry
- 2014

Tidskriftsartikel (refereegranskat)abstract
- The manufacturing industry constantly strive to develop the competencies of their expert production engineers in order to achieve and maintain a competitive advantage. Research shows that the absorptive capacity of a firm is central in order to reach such a goal. The absorptive capacity is the firm´s ability to recognize the value of new external information, assimilate it, and apply it to commercial ends, and thereby exploit the conditions for innovation. In this paper the concept of absorptive capacity is used as a lens for analyzing managerial rationales for engaging in technology enhanced competence development projects. Through interviews with key informants in 15 manufacturing firms we study the capabilities and readiness that organizations need for participation in e-learning initiatives. We present a framework of readiness for technology enhanced competence development comprised of the following interrelated constructs; awareness, e-learning maturity, dynamic capability and co-creativity. Results show a broad variation of levels within the constructs among the firms. Notable is the low level of e-learning maturity and dynamic capability. We argue that e-learning maturity is dependent on all four constructs.

Konferensbidrag (refereegranskat)abstract
- In this paper we aim to understand management’s perceptions of knowledge and competence development to inform the design of technology enhanced learning activities integrated in the workplace. Work-integrated learning can be viewed with the university lens on studies of formal education integrated in the workplace setting, but here we rather emphasize the conditions of the workplace as implications for design of successful e-learning initiatives. We conducted interviews with 15 manufacturing industries in Sweden and used qualitative content analysis approach to interpret the text data. Results show that companies describe a rich variation of work-integrated learning activities, but the step towards external collaboration with academia for co-production of knowledge is marginal. Also, broad-minded work for innovations is limited. This imply the need for well-planned design of richer collaborative acitivites between academia and organizations through use of media technology to encourage competence development.

Tidskriftsartikel (refereegranskat)abstract
- Automobile final assembly operators must be highly skilled to succeed in a low automation environment where multiple variants must be assembled in quick succession. This paper presents formal user studies conducted at OPEL and VOLVO Group to identify assembly training needs and a subset of requirements; and to explore potential features of a hypothetical game-based virtual training system. Stakeholder analysis, timeline analysis, link analysis, Hierarchical Task Analysis and thematic content analysis were used to analyse the results of interviews with various stakeholders (17 and 28 participants at OPEL and VOLVO, respectively). The results show that there is a strong case for the implementation of virtual training for assembly tasks. However, it was also revealed that stakeholders would prefer to use a virtual training to complement, rather than replace, training on pre-series vehicles.

Konferensbidrag (refereegranskat)abstract
- To handle the complex and flexible manufacturing of today it is vital to have well functional information systems for the operators so that they know when, what and where to assemble. The current designs of assembly work instructions differ much between companies, but also between plants within the same company. The digitalization trends and initiatives such as Industry 4.0 show the manufacturing industry the advantages to incorporate new methods and tools into their businesses. Even though manufacturing IT systems are designed to be adaptive to product and volume changes, they are still widely characterized by their rigid structures. Making large changes to manufacturing IT systems with comprehensive structures is complex and requires large amounts of resources. Therefore, it is important for the manufacturing companies to make the correct investments. In previous studies, two current state analyses have been conducted with the aim to map manufacturing engineering processes and IT systems producing assembly work instructions in a mass customization context. This paper presents results from the third part of a longitudinal study which focuses on identifying operators’ information needs in manual assembly of heavy vehicles. This third study aims to identify the information gap between the current state and the wanted state by assessing information needs at 13 assembly stations in three plants belonging to a global production network. The purpose is to identify design requirements for future assembly information systems enabling the practical use of the digitalization.

- PurposeThe purpose of this paper is to describe challenges the manufacturing industry is currently facing when developing future assembly information systems. More specific, this paper focuses on the handling of assembly information from manufacturing engineering to the shop floor operators.Design/methodology/approachMultiple case studies have been conducted within one case company between 2014 and 2017. To broaden the perspective, interviews with additionally 17 large and global manufacturing companies and 3 industry experts have been held. Semi-structured interviews have been the main data collection method alongside observations and web questionnaires.FindingsSix focus areas have been defined which address important challenges in the manufacturing industry. For manual assembly intense manufacturing company, challenges such as IT challenges, process challenges, assembly process disturbances, information availability, technology and process control, and assembly work instructions have been identified and hinder implementation of Industry 4.0 (I4.0).Originality/valueThis longitudinal study provides a current state analysis of the challenges the manufacturing industry is facing when handling assembly information. Despite the vast amount of initiatives within I4.0 and digitalization, this paper argues that the manufacturing industry needs to address the six defined focus areas to become more flexible and prepared for the transition toward a digitalized manufacturing industry.

Tidskriftsartikel (refereegranskat)abstract
- Products become more complex as the general technology development reaches new levels. These new technologies enable manufacturing companies to offer better products with new functionalities to their customers. Complex products require adequate manufacturing systems to cope with changing product requirements. In general, manufacturing of this type of products entails complex structured and rigid IT systems. Due to the system’s complexity and comprehensive structure, it becomes challenging to optimize the information flow. There are improvement potentials in how such systems could be better structured to meet the demands in complex manufacturing situations. This is particularly true for the vehicle manufacturing industry where growth in many cases has occurred through acquisitions, resulting in increased levels of legacy IT systems. Additionally, this industry is characterized by high levels of product variety which contributes to the complexity of the manufacturing processes. In manual assembly of these products, operations are dependent on high quality assembly work instructions to cope with the complex assembly situations. This paper presents a current state analysis of data and information handling in assembly information systems at multiple production sites at a case company manufacturing heavy vehicles. On basis of a certain set of characterizing manual assembly tasks for truck, engine and transmission assembly, this work focuses on identifying what data that is used in manufacturing engineering processes and IT systems to produce assembly work instructions. This work aims to identify gaps in the information flow between manufacturing engineering and shop floor operations.

Tidskriftsartikel (refereegranskat)abstract
- The manufacturing industry is in a changing state where technology advancements change the mindset of how manufacturing systems will function in the future. Industry 4.0 provides manufacturing companies with new methods for improved decision-making processes and dynamic process control. Despite this ambition, the manufacturing industry is far away from implementing this approach in practice. Assembly information systems will play an even more vital role enabling information transfer from product design to shop floor assembly in the future. To prepare the industry for these changes that are foreseen and for those that are yet to be discovered, a learning factory environment is vital. Such an environment is intended to support the industry during the development of assembly information systems. This paper presents an industrial demonstrator which incorporates well-known methods for improving assembly work stations with the perspective on assembly information systems. These methods are still not widely used in manual assembly intense manufacturing companies. This demonstrator illustrates how established theories can be practically used when designing future assembly information systems. The demonstrator will be used to validate functionalities and requirements for future assembly information systems.

- This chapter covers the main reasons for the use of Digital Human Modelling tools in the automotive manufacturing industry. The focus is entirely on physical digital human modelling, not on cognitive digital human modelling. Important aspects regarding work process and organization are covered as well as how companies deal with some identified shortcomings. The chapter also describes how fewer physical prototype vehicles has made it necessary to find new methods for training of operators adapted to the new conditions. Finally, also an example of a simulation case from the order of the case to the result presentation is given.

Computer Support for Preparatory Training in Automotive Assembly
- 2009
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The automotive industry is facing new challenges constantly. Reduction of waste and time-to-market, the ability to offer the customer a unique combination of options and high product quality are examples of issues that have been in focus during the last decade and are still considered very important. Shorter product life cycles and the fact that completely different vehicles are often produced on the same assembly line are, together with the aforementioned issues, factors that influence the way new vehicles are launched and produced. The assembly operators constitute a central part of the production system and their skills and ability to produce high quality are issues that will always be in focus. Cost reduction and a change towards more computer based product development methods provide a potential to reduce prototype vehicles to a minimum or even completely. The latter change has affected the training of operators’ prior vehicle launches in a dramatic way since the traditional way to utilize components from prototype vehicles for training purposes has become quite limited. Consequently the new conditions have created a strong need for alternative training methods. The starting point for the work has been to find methods that are based on already generated engineering information and use them on ordinary desktop computers for the training of experienced assembly operators. The work has been carried out as case studies, all performed in an assembly plant with experienced assembly operators as subjects. The research has been concentrated on understanding this specific area and how this type of training should be organized to best support the operators during a launch of new vehicles. The result shows that computer based training is an effective tool and preparatory training of assembly operators can be performed in an efficient way by using the defined and explored expert based learning model. The model provides training that supports all operators, including the leaders of the operator teams and it connects the training environment and the real assembly situation on the assembly line in a positive way. A defined framework with four operator knowledge phases named: Product, Process, Assembly sequence and Finesse are presented. The results from the case studies, combined with the defined framework constitute the base for a proposed concept for computer based preparatory training. The concept includes two major training activities and one of them –- is the focus of this work. The aim of this work has been to develop an understanding for how computers can be used in the training of operators, especially to prepare and support learning in launch training. With the accomplished studies an important step towards deeper understanding has been achieved. However, additional research is needed in order to verify and further develop the proposed concept.

Tidskriftsartikel (refereegranskat)abstract
- In this article, two field experiments, conducted in an automotive assembly plant, evaluate how computer-based training of operational sequences and related quality information can support the assembly performance of the operators. The experiments were performed during the launch of a new vehicle. A comparison was made of learning progress and quality performance between a reference group of operators that only had regular training and a test group for which some of the regular training was replaced with individual computer-based training. Both quantitative measures of the quality output and questionnaires and observations were used to evaluate the effects of computer-based training. The results show a clear positive difference in learning progress and improvements in quality output for the test group compared with the reference group. This combined with positive attitudes expressed by the operators and their team leaders shows that this type of training is an effective way to train operators during launches of new vehicles in automotive production. © 2014 Wiley Periodicals, Inc.

- This article describes two studies conducted to compare assembly performance and learning rate between computer based training and traditional training of skilled assembly operators. The studies were performed with pre-series production parts from a car cockpit and they were integrated as part of the overall training activities during a new vehicle product launch. The computer based training tool used was a desktop based commercial VR tool with focus on cognitive interactive procedural learning. Both studies indicate that computer based training can replace instructor based training for this level of assembly complexity and that it has a positive effect in preparing skilled operators

Training Virtually Virtual
- 2012

Ingår i: International Journal of Advanced Corporate Learning. - 1867-5565. ; 5:3, s. 29-36
-
Tidskriftsartikel (refereegranskat)abstract
- This paper reports from a longitudinal study of a Swedish manufacturer in the automotive industry, where a series of studies have explored the potential and limitations of computer-based training of assembly operators. The study is focusing on two supplementing sets of target variables – operators' attitudes and the quality output from operators in real production. Starting with small-scale studies where proof-of-concept for virtual training is established, the research moves on to comparative studies where different computer-based learning models are contrasted and evaluated. The research design ends with large-scale field experiments assessing the effects of computer-based training in terms of quality output. The results clearly demonstrate that computer-based training, when integrated with training of standardized work procedures, outperforms traditional methods for operator training, regardless of the content and the context of the assembly operation. The findings of the study are synthesized into a design framework for virtual training where cognitive and craftsmanship training is contrasted to the learning of product, process, sequence and finesse of assembly.

Virtual Training - Preparatory Training in Automotive Assembly

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The automotive industry is constantly facing new challenges. Reduction of waste and time-to-market, ability to offer the customer a unique combination of options as well as high product quality are examples of issues that have been in focus during the past decade and still considered extremely important. Together with the aforementioned issues, other factors that influence the way in which new vehicles are launched and produced are shorter product life cycles and the fact that completely different vehicles are often manufactured on the same assembly line. Assembly operators constitute a central part of the production system and their skills and ability to ensure high quality will always be in focus. Cost reduction and a shift towards more virtual product development methods provide the potential to reduce prototype vehicles to a minimum or even completely. This has dramatically affected the training of experienced assembly operators prior to the launch of a new vehicle since the traditional way of utilizing prototype vehicle components for training purposes is more or less non-existent. Consequently, the new conditions have created a strong need for alternative training methods. The starting point for the present work was to identify methods based on previously generated engineering information and use them on ordinary desktop computers for the training of experienced assembly operators. The work was carried out as case studies, all performed in an assembly plant with experienced assembly operators as subjects. The research mainly concentrated on understanding this specific area and how such training should be organized to best support the operators during a new vehicle launch. The results demonstrated that virtual training is an effective tool for preparatory training of assembly operators as well as training in the later stages when detailed assembly sequences and quality related issues (finesse) are in focus. Preparatory training can be performed in an efficient way by using the defined and explored expert based learning model. On the other hand, assembly sequence and finesse training is appropriate for the defined system learning model. The design of the studies was based on a defined framework with four operator knowledge phases: Product, Process, Assembly sequence and Finesse. The results of the case studies combined with the above-mentioned framework constituted the basis for a proposed virtual preparatory training concept. This concept included two major virtual training activities where the first two knowledge phases formed the base for the first activity and the two final phases the foundation for the second.The aim was to develop an understanding of how computers can be used in the training of operator s, especially in the preparation and support of launch training. As a result of our studies, an important step towards a deeper understanding has been achieved.

Tidskriftsartikel (refereegranskat)abstract
- Inspection in Aerospace industry can, as well as many other industrial applications, benefit from using Augmented Reality (AR) due to its ability to superimpose helpful digital information in 3D, leading to fewer errors and decreased mental demand. However, each AR device has advantages and disadvantages, and not all AR devices are suitable for use in industrial settings. We compare a tripod-fitted-adjustable-arm tablet-based AR solution (Apple iPad Pro) to head-mounted AR (Microsoft HoloLens 2) and a traditional, computer screen-based human-machine interface (HMI), all three designed to guide operators based on previously performed AI-based image analysis. Following an iterative design process with three formative evaluations, a final field test in a real industrial shop floor engaging 6 professional inspectors revealed an overall preference for the tripod-fitted iPad variant which receiving the best scores in most dimensions covered in both a usability-focused SUS questionnaire (score 71) and a NASA-RTLX form focused on perceived workload. More specifically, the tripod-fitted iPad was considered more usable (SUS) than the classic computer display HMI (M=5.83, SD=4.92, p=0.034, N=6); the temporal demand (NASA-RTLX) was considered lower using the iPad compared to both HoloLens 2 and the HMI (M=6.67, SD=4.08, p=0.010; M=10.83, SD=9.70, p=0.040, N=6), respectively.

- Wooden-house assembly is an area where still a big part of the work is done manually. In this case study, pairs of operators compose large wooden pieces together based on paper-print instructions complemented by visual guidance in the shape of laser marks projected from lasers mounted in the ceiling, based on Computer-aided design (CAD) data. Augmented Reality (AR) head-mounted displays (HMD) offer a unique platform for providing instructions and additional information superimposed in the work environment and thus can provide guidance in a cognitively ergonomic way. A particular advantage compared to other computing platforms is that the operators have free hands and can perform the manual work and follow guidance simultaneously. We present an evaluation of a prototype that dynamically transforms a CAD data file with design and measurements of wooden trusses to be manufactured, into an AR-based guidance system developed in Unity for Microsoft HoloLens 2 devices. We used an iterative participatory design process for prototyping and think-aloud protocol combined with observations for evaluation, involving professional assemblers in different stages of the process. Participants found the solution to potentially save time in their everyday work and simplify the task by offering increased visibility of the marks compared to the existing laser projection. Large-scale deployment of the system is still facing design challenges of which some are also discussed in the paper.

Multimodal Augmented Reality and Subtle Quidance for Industrial Assembly : A Survey and Ideation Method

Tidskriftsartikel (refereegranskat)abstract
- Industrial manual assembly is a relatively established use case for emerging head-mounted Augmented Reality (AR) platforms: operators get visual support in placing pieces depending on where they are in the assembly process. However, is vision the only suitable sensory modality for such guidance? We present a systematic review of previous work done on multimodal guidance and subtle guidance approaches, confirming that explicit visual cues dominate. We then outline a three-step method for generating multisensory guidance ideas intended for real-world task support based on task observation that led to identification of 18 steps in truss assembly, brainstorming AR guidance approaches related to assembly and maintenance, and mapping of brainstorming results to the observed task. We illustrated the use of the method by deploying it on our current mission in producing AR guidance approaches for an industrial partner involved in designing and assembling wooden trusses. In this work, we went beyond the standard visual AR guidance in two ways, 1) by opening for guidance through auditory, tactile, and olfactory sensory channels, 2) by considering subtle guidance as alternative or complement to explicit information presentation. We presented a resulting set of multisensory guidance ideas, each tied to one of the 18 steps in the observed truss assembly task. To mention a few which we intend to investigate further: smell for gradual warning about non-imminent potential hazardous situations; 3D sound to guide operators to location of different tools; thermos-haptics for subtle notifications about contextual events (e.g., happening at other assembly stations). The method presented helped us to explore all modalities and to identify new possibilities. More work is needed to understand how different modalities can be combined and the impact of different modality distractions on task performance. © 2022, Springer Nature Switzerland AG.

- The advantages and importance of university-industry collaboration, particularly in curriculum design and delivery, are well-known. However, although curriculum development models are available in the literature, very few are sufficiently concrete to be applicable in practice or are generalizable beyond their discipline of origin. In this paper, a co-operative model based on the Plan-Do-Study-Act cycle is presented and described. An example of its application in the curriculum design of two courses in welding within a Manufacturing Engineering Master's program is detailed. The model was found successful based on the evaluation of the courses by students, teachers, and the industrial representatives involved. Therefore, it proved to be an effective tool for bridging the gap between industrial needs and academia in the field of Manufacturing Engineering education. At the same time, the methodology is generalizable and is applicable to any field of education.
