- SummaryA work procedure for virtual product and manufacturing engineering has been developed at the Volvo Car Corporation. For the first time this was fully adhered to during the development of the P28/XC90 car model. The working methods comprise both virtual and physical analysis of different aspects of the product and production process, such as packing, assembly ability and ergonomics. A decision was taken in January 2001 to make an evaluation of the virtual working methods, for which a research team from the National Institute for Working Life and Chalmers University of Technology was engaged.The purpose was to evaluate how well the virtual working methods functioned with regard to ergonomics aspects of assembly work - and to what degree they could be applied for early identification of ergonomics problems. About 30 interviews with members of different development teams (module teams) were carried out for the evaluation. Evaluations of the assembly work for a selected number of PIIs1 for P28 were also made, starting with virtual series2 5 (VS5) in February 2001 ending with the pre-series PTO1 (Pre try-out 13) in November 2001. The overall results showed that the virtual participative working methods worked well in general and the members of the module teams (project teams) were very positive to the usage of virtual tools. A large number of ergonomic problems were identified and corrected but the number of ergonomic simulations was lower than expected. The reason for this was said to be a lack of ergonomics competence. Nevertheless the module teams believed that there was a greater potential for identifying and solving several ergonomic problems in early project phases than was the case in this study. An overall important outcome was the recommendations to the company for how to improve virtual working procedures, follow-ups of simulation results and virtual tools for the future.

- An example of a result from a long-term cooperation with Lund University (together with professor Roland Akselsson at the Department for Work Environment) there some of the authors (Engström) gained extensive grants (Wallenberg Stifelsen regarding equipment as well as other founding from e.g. the Swedish Work Environment Found). In this case the just mentioned EU-financing.

Participatory Ergonomics in Product Development and Workplace Design Supported by Computerised Visualisation and Human Modelling
- 2001
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis discusses and reports on improvements in workplace design and product development, with focus on production systems in industrial environments. The processes of workplace design and product development are considered to be both complex and placed under significant time pressure. Methods commonly used often result in poor ergonomics and inefficiency, which gives unsatisfactory results for the end users of the workplace. Participatory ergonomics represents an approach involving the people who know the work process or who actually use the workplace or product. Besides other positive effects, this makes it possible to improve the workplace or product. When using participatory ergonomics, it is important that solutions and ideas are presented in such a way as to reach a greater understanding. Computerised visualisation is a means to reach this understanding. Computer manikin software is a modern tool, which can be used to visualise and model human aspects. There is still a general lack of knowledge on how participatory ergonomics may be implemented and, in particular, how computerised visualisation and human modelling affect the participatory ergonomics process. The objective of the thesis was to provide new knowledge, based on industrial case studies, about the participatory ergonomics process as well as to further develop the existing theoretical base. An additional objective was to provide new knowledge about the role of computerised visualisation and human modelling in the participatory ergonomics process. Four case studies have been carried out, ranging from the industrial environment producing piston rings, via materials kitting for car assembly and the development of new buses, to the development of a workplace for the International Space Station. In all case studies, a participatory ergonomics approach has been used. The participatory ergonomics approach has been combined with computerised visualisation, and two case studies have also included human modelling. Results show that the involvement of workers, i.e. participatory ergonomics in its basic interpretation, gives positive effects. However, it is suggested that the worker need not be involved close to the core participatory ergonomics process but can instead act in an adjacent loop. It is proposed that a new dimension, named Activity, be added to the existing participatory ergonomics framework. Finally, a new concept of participatory ergonomics is proposed - Participatory Ergonomics Design (PED). The introduction of PED is aimed at encouraging the use of participatory ergonomics in the product design phase, which is not commonly done today. The results illustrate that computerised visualisation supports participatory ergonomics and that the computerised tools used are becoming more complex. Also, additional prerequisites are needed when using computer manikin software as tools for ergonomics analysis, which is especially important if the analysis is extensive.

Konferensbidrag (refereegranskat)abstract
- In this case study, a human factors engineering (HFE) analysis was carried out in the preliminary design phase of the Cupola. Cupola is a European Space Agency (ESA) module for manned space flights for the International Space Station (ISS) as part of a Barter Arrangement between ESA and the United States National Aeronautics and Space Administration (NASA). Manikin software was used early in the design process before the production of any flight hardware. The manikin analysis was supported by the use of hierarchical task analysis, a file exchange protocol and a relational database. This paper describes methodological aspects of the use of the supporting methods. Results show that hierarchical task analysis, a file exchange protocol and a relational database are prerequisites for successful extensive manikin analysis.

Konferensbidrag (refereegranskat)abstract
- In this case study, a human factors analysis was carried out in the preliminary design phase of the Cupola, a European Space Agency (ESA) module for manned space flights for the International Space Station (ISS). The manikin software Jack® was used early in the design process before any flight hardware production. All Cupola astronaut tasks were evaluated in a virtual environment of the Cupola. Methodological aspects concerning the analysis are described, e.g. file processing, use of coordinate systems and the use of a prior task analysis. Results show that the thorough manikin analysis supported with the hierarchical task analysis results, was an important help in the design process.
