- Humans are indispensable in the manufacturing industry as its complexity increases in an Industry 4.0 context, mainly due to changing customer demands. Managing the challenges of increased complexity can create a competitive advantage for SMEs. Technologies which enable the emerging phenomenon of Industry 4.0 have the possibility to simplify the sharing of information and knowledge among people at work, especially for Operator 4.0. However, few SMEs have actually implemented such technologies for this purpose. Therefore, this paper aims to create an understanding of the current state and challenges which need to be overcome, and further, to provide some insights on future possibilities by identifying the stages of Industry 4.0 development of SMEs with regards to their capabilities. This qualitative interview study focuses on how human-centered production processes are currently supporting assembly and office work. Two Swedish SMEs were studied, where almost all of their operators and management team on site were interviewed individually concerning their views on their current capabilities. The interviews were thematically analyzed with regards to the state-of-the-art research, and results show that the case companies are in some aspects digitized with regards to computerization and connectivity, but have some challenges in making the shared production-related information more visible and transparent, especially on shop-floors where most information and knowledge are shared through word of mouth or with pen and paper. Conclusively, the studied SMEs have started their digitalization journey, but further Industry 4.0 development needs to align with their respective conditions and needs. While Industry 4.0 enabling technologies that support information and knowledge sharing are emerging, organizational development can support the implementation of such technologies, which should be the focus for future research.

Konferensbidrag (refereegranskat)abstract
- Operators remain as important resources in complex final assembly. To sustain a multi-variant production, it is necessary for operators to manage high demands from a cognitive workload perspective. In such situations, work instructions can support operators cognitively. However, work instructions are often insufficient or unused in final assembly. In this paper, results from testbed experiments are presented where assembly work was supported by different types of work instructions with differing information content. Results indicate that operator performance in terms of perceived cognitive workload and information quality are affected by the presented content of information in work instructions.

Tidskriftsartikel (refereegranskat)abstract
- In the digital transformation of manufacturing companies towards Industry 4.0, shop-floor operators of the future, Operator 4.0, will require digitalized presentation of information as cognitive support for their work. This paper explores five industrial cases where Information Support Technology have been conceptualized and developed. These cases have exemplified how digitalized presentation of information can be approached with considerations of operators with varying cognitive work situations and production characteristics. Furthermore, these new technical capabilities have increased the level of cognitive automation to support operators’ individual abilities to perform their work in an increasingly more complex production environment. In conclusion, Information Support Technology in the service of Operator 4.0 is intimately linked with digitalization strategies for transformation towards Industry 4.0.

HOW CHANGES IN COGNITIVE AUTOMATION CAN AFFECT OPERATOR PERFORMANCE AND PRODUCTIVITY
- 2014
-
Ingår i: The sixth Swedish Production Symposium.
-
Konferensbidrag (refereegranskat)abstract
- To predict system performance, understanding what affects operator performance and productivity is important. This notion was tested in a LEGO experiment including 40 students. After introducing changes in assembly instructions and material façade operator performance and productivity was increased. The aggregated results gave an indication of how cognitive automation affects the operators’ initial assembly performance. Industrial studies are needed to ensure observed trends and to further study the impact of cognitive automation characteristics. The trends however point toward that cognitive support has an impact on the final assembly and it is therefore possible to achieve better operator performance if instructions and material façade are improved.

- The manufacturing industry faces immense challenges for maintaining and increasing their productivity and flexibility. In this context, it is important for companies to ensure that their employees have the relevant data, information and knowledge necessary to make well-informed decisions. Due to recent development with Industry 4.0 enabling technologies that create new possibilities, the amount of available data, information and knowledge increase rapidly, but the insights into how to utilize it to its full potential are still lacking. In this paper, a human-centred perspective has been applied, aiming at improving how to cognitively support humans at work with new Industry 4.0 enabling technologies. Heavy emphasis is placed on people’s requirements and preferences of data, information and knowledge for enhancing their performance and satisfaction at work. This paper examines the relationship between existing literature on dissemination of data, information and knowledge within the manufacturing industry with state-of-the-art research on Industry 4.0. The outcome of the research recognizes the increased importance of utilizing data, information and knowledge for people at work, facilitated by exploiting the new possibilities from Industry 4.0. To accomplish this, it is concluded that there exists an urgency to design: both a holistic framework for identifying and accommodating individuals’ needs and expectations of relevant data, information and knowledge; and demonstrators and concepts to simplify the implementation of Industry 4.0 enabling technologies that support the aforementioned dissemination of data, information and knowledge.

- The manufacturing industry is becoming increasingly more complex as the paradigm of mass-production moves, via mass-customization, towards personalized production and Industry 4.0. This increased complexity in the production system also makes everyday work for shop-floor operators more complex. To take advantage of this complexity, shop-floor operators need to be properly supported in order to perform their important work. The shop-floor operators in this future complex manufacturing industry, the Operator 4.0, need to be supported with the implementation of new cognitive automation solutions. These automation solutions, together with the innovativeness of new processes and organizations will increase the competitiveness of the manufacturing industry. This paper discusses three different aspects of production innovation in the context of the needs and preferences of information for Operator 4.0. Conclusively, product innovations can be applied in the manufacturing processes, and thus becoming process innovations, but the implementation of such innovations require organizational innovations.

Supporting individual needs for intra-organisational knowledge sharing activities in pre-industry 4.0 SMEs
- 2018
-
Ingår i: Proceedings of the International Conference on Intellectual Capital, Knowledge Management and Organisational Learning, ICICKM. - : Academic Conferences and Publishing International Limited. - 2048-9803 .- 2048-9811. - 9781912764099 ; , s. 160-170

Konferensbidrag (refereegranskat)abstract
- The complexity of modern manufacturing industry and the emergence of Industry 4.0 puts changing cognitive demands on human operators at work. Operators in this environment, Operator 4.0, will share knowledge through the use of new digital technologies that should be implemented in parallel with an organizational development towards Organization 4.0. On an individual level within the organization, people benefit from understanding their own knowledge needs and gain necessary knowledge through knowledge sharing activities. In pre-Industry 4.0 organizations, this is done primarily through meetings. Originally developed to create smart meetings in smart factories, an elaborated version of the MEET model (Gullander et al, 2014) is used in this paper to evaluate the needs for sharing of tacit and explicit knowledge, both in regards to how it affects the Information System and the Organization System. By adding a systematic process approach to mapping individual knowledge needs related to production activities, these needs can be identified for each process step. By using this systematic approach to apply the MEET model, two Swedish SMEs within the manufacturing industry have developed their knowledge sharing activities. This human-centred study, based on questionnaires and interviews, focuses on how shop-floor operators perceive changes in knowledge sharing activities due to the use of the MEET model. Novelty in this research lies in the attempt to link the technology-intensive Industry 4.0 development with an organizational emphasis. Results show that the applied method can be used to pragmatically improve knowledge sharing from certain aspects, but further research is required to determine the correlation between different areas and their effect on knowledge sharing. This paper suggests that knowledge sharing in organizations can be benefitted from Industry 4.0 enabling technologies, introducing this as Organization 4.0.

- Learning factories play an important role when studying multi-disciplinary problems. Such a problem is to support operators in multi-variant assembly. Multi-variants cause problems with product quality, production time as well as cognitive load and therefore it is important to find ways to support operators in this context. To assess the effects of multi variants, a design concept were developed in a learning factory environment (SIILab, CPPS-testbed). The concept was constructed at a conveyer belt with three assembly stations using Casat software for instruction presentations. The following aspects were included in the human-centered learning factory: studying the introduction of advanced automation, managing product variety, supporting operators in finding information and supporting existing human-automation interactions.
