Tidskriftsartikel (refereegranskat)abstract
- This article presents a materials kitting case study, using an alternative method for materials killing: the traditional picker-to-material principle was replaced with a material-to-picker approach. The Study was made in a materials supply workshop of an automobile plant shortly after this kitting process had been introduced. The materials kitting was video recorded and the material pickers' physical exposure was assessed using ambulatory equipment to make an integrated registration of muscular activity, work postures and movements. The material pickers assessed work situations perceived as physically stressful. The materials kitting showed improved productivity as compared with other kitting methods. The study indicated that the work situation offered pickers low levels of physical exposure. The picking work was rather light but involved great repetitiveness in arm movements. The material pickers experienced the work as repetitive and having some physically stressful work situations. The integrated analyses showed: (1) that exposure in picking operations was similar to, but could be distinguished from, other work activities and (2) that picking from one type of storage package, Euro pallets, resulted in higher exposure than picking from plastic containers. More studies are needed on the implications of exposure levels in materials picking.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This publication explains the differences between administrative and physical modularisation, which in turn implies new opportunities to deal with so-called just-in-time (JIT) deliveries. Thus are e.g. the nowadays coagulated road traffic system, in fact, possible resolve (as were the product planning system that hampered the performance of the Volvo Uddevalla plant, it was relying on traditional codification of the product variants, thus were the reduced so-called production losses never possible to accumulate between automobiles for each and every small parallel workgroup) (the information system was totally new – nothing external was allowed to enter the shop floor of this plant – but still were some assembly line approaches was still at hand). A comment: The most socio-technically advanced assembly system designs inventible requires reformed/reconfigured information systems dealing with product data (which in turn defines the product architecture and product variation). In fact, no any such (real-life) plant or assembly system would work as anticipated otherwise. And this publication is to some extent describing some selected aspects of this (very) dilemma (changing information systems are usually not something considered than designing assembly systems) (thus are totally new plants – and in turn totally new information systems – most often the real practical change to create something unorthodox) (however, which scientist will gain such opportunities, this is really rare, i.e. the projection of the Volvo Uddevalla plant was thus an exception and the trust given by the industry – by Volvo Uddevalla project organisation – was appreciated by some of the authors).

Assembly Work Structuring Based on Restructuring and Transformation of Product Information

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This publication partly explains how we had managed amalgamate manufacturing engineering according to our interpretation and e.g. Gestalt psychology (i.e. for the most socio-technically advanced assembly system designs). This is something that is elaborated further and better repetitively in other publications registered in Chalmers Public Library (CPL) (especially is this the case in some of the latest preprints/manuscripts). That is, how the learning and training principles advocated by the senior research competency within vocational learning and training were realised in practice for full-scale production purposes.
