Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter focuses on experiences concerning the development of assembly systems within the Volvo Corporation. It provides research and development work within the Swedish automotive industry. The chapter considers a specific trajectory concerning assembly system design in the Swedish automobile industry, generalising the Volvo Kalmar and Volvo Uddevalla experiences. During 1988–1990, the managers at Volvo were planning the manufacturing of the new 800 model at the main Volvo Torslanda plant, as well as looking for a total redesign of the plant. The average product quality in the Uddevalla plant was high–in fact better than in Volvo's line assembly plants–but the product quality varied considerably. Productivity and flexibility proved to be superior to traditional serialassembly systems. Two ways of decreasing the time losses are to introduce parallel flow assembly systems–that is assembly systems consisting of many, short, unpaced flows–or to introduce buffers between work-stations.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Consumer report ("avnämarrapport" in Swedish) for a research foundation (Styrelsen för Teknisk Utveckling, Stockholm). A comment: Publishing consumer reports was the praxis during this (early) period of time at Chalmers University of Technology, as well as probably at some other universities. This means that frequent and vast academic publication by means of e.g. conference papers and refereed contributions to scientific journals was almost unheard of. At least so for some of the applied science disciplines. However, today are the situation indeed very different (i.e. earlier was the publication in many respects focused on trying to satisfy the executive administrator the research foundation in question etc.). To be more precise, this early praxis was definitively the case for the research and development work carried out at the Department of Transportation (a broadly applied science discipline), which was characterized by more practical strives to e.g. engineer research results. Rather than relying on truer scientific efforts in a narrower sense. Functional satisfaction (i.e. something engineered work as planned instead verification/falsification of a hypothesis) was judged as being a primary aim of this research and development work. Therefore are (in the context of the publications registered in Chalmers Public Library CPL) the author making distinctions between consumer reports, on one hand. And, one the other hand, reports and preprints (manuscripts), while instead the academically orientated publications are various sort of scientific contributions presented at conferences or published in scientific journals (actually it is somewhat more complex, but further explanations are omitted here). The consumer reports were aimed at a various external organization with who the authors cooperated, and these are in many cases not available in PDF format to be easily read by logging in at CPL. This particular approach has judged as being fair/relevant fair in order to mirror of work conducted by the author or authors during the passing decades. Besides, the competencies at Chalmers Library, who actually have been very helpful, have not managed to provide appropriate answers to the various questions implied being at hand just above (this despite trying to get hold of such answers, hence this very comment).

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This manuscript is an extensive book (or preprint not yet finished to due to one the author’s retirement) summaries four decades research and development work dealing with development work of alternatives to assembly lines and assembly line work, as have been the case for one of the two authors from a technical point of departure (he is a senior research competency in mechanical engineering). On the other hand, the other authors have an even longer time perspective, but he has a social science background (he is a senior research competency within sociology for more than four decades). That is, they have been working at Chalmers University of Technology respectively at Gothenburg University all throughout their professional life. This while they both are belonging to a normative sociotechnical research tradition earlier at hand in the Gothenburg area, which actually has emanated from specific precursors at Gothenburg University (i.e. mainly professor Edmund Dalhström at the Department of Sociology), this research tradition was later on brought over to Chalmers by professor Ulf Karlsson responsible for operation management at the same university. It is fair to state that this research area required the amalgamation of technical as well as social science aspects. Efforts that during the passing years have been substantiated by extensive help and support from the Swedish automotive industry (Saab Scania and Volvo companies, as well as other parts of the industry) and also from several governmental research foundations. In fact, a truer cross and multi-science research approach than what usually is at hand has always been required. The extensive book manuscript is exceeding more than 600 pages. Twelve chapters exists as well as also a number of freestanding appendixes and the necessary (all-pervading) definitions of primary concepts and term in combination with explaining various synonyms and homonyms (a particular dilemma for cross and multi-science approaches) (i.e. are we in agreement with the text it alone, or are we eventually together understanding the underlying meaning). Moreover, the text is scrutinized by word process programs in form of Word as well as by the professional English check-up program Grammarly) and all of the necessary figures are completed. i.e. several revisions of this manuscript have been iterated first between the authors and later on against other parties. Most notable are external revisions by two senior research competencies (professor David Bennet responsible for operation management at Aston Business School, Birmingham and professor Lennart Nilsson responsible for vocational learning and training at Gothenburg University, Gothenburg). The authoring just described (involving the initiated hinted just above) have occupied our minds for more than one decade (our co-authoring and work with specific Japanese research colleagues, have most certainly underlined a need for careful writing, since among other things just nicking the practitioners’ nomenclature will be misleading, as is also the case while relaying on one or a few scientific research areas) (see some of the other publications registrated in Chalmers Public Library CLP) (it is most certainly an extensive research area, and the skills needed to be mastered in order to understand are indeed wide). The underlying principles of any (real-life) assembly system must, according to our understanding, are inventible required to be explained. Thus, it is important for the analyst to grasp whether or not the principle applied is correct or if the practice is questionable. This means, metaphorically speaking, is the original drawings accurate or have the execution (practice) faulty. The two most sociotechnically advanced (real-life) assembly systems both proved to be successful (more efficient and flexible in relation to comparable assembly lines, and work and work conditions were far better). They were both based on correct principles (i.e. the nowadays defunct Volvo Uddevalla plant and the so-called assembly docks at the Volvo Tuve heavy truck chassis plant located in Gothenburg). As will become evident by the content brought forward in this extensive book manuscript. 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).

Tidskriftsartikel (refereegranskat)abstract
- This paper reports on a crucial learning experience relating to design principles applied in the Volvo Car Corporation final assembly plant in Uddevalla, Sweden. These principles include the concept of holistic learning, specifically through the creation and transformation of complementary, interrelated physical, semantical, and cognitive structures. We report on the learning environment and learning aids, as well as the learning method applied to the assembly of one-quarter of an automobile performed by one single person. Through the application of this learning concept, it proved possible to dramatically reduce the learning time required for long cycle time assembly work, making cycle times of 2 hours or more a practical proposition for full-scale automotive manufacturing today.
