Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Consumer report for the company in question (the Volvo Automobile Company and the Volvo Torslanda plant) which is financed by the company and partly also by a research foundation. It is a matter of a work that in this particular case were carried out during nine years in a number of experimental workshops located outside the Chalmers University of Technology. These workshops were financed by the Volvo Automobile and Truck companies. This achievement, as the final contribution to the Swedish automotive industry after having already treated this research field/problem area for more than two decades before this particular period if time (involving several junior and senior research competencies, as well as industrial and governmental foundings).

Tidskriftsartikel (refereegranskat)abstract
- The classical dynamic lot size problem without backlogging is usually solved with the aid of various heuristics. Most heuristics are sequential, i.e. the demand is considered period for period, and a decision whether to include the demand in a certain period in the preceding batch is taken without regarding the future demand. Recently, it has been shown how to design a sequential lot sizing rule that will optimize the average performance, provided that a typical demand looks like a sequence of independent and identically distributed random numbers. The purpose of this paper is to evaluate if and how this methodology can be implemented in practice. The new lot sizing techniques are evaluated in a simulation study for different types of demand.

Naturligt grupperat arbete vid Volvo Lastvagnar – Slutrapport

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Consumer report for the company in question (the Volvo Truck Company) which is financed by the company and partly also by a research foundation. It is a matter of a work that in this particular case were carried out during nine years in a number of experimental workshops located outside the Chalmers University of Technology. These workshops were financed by the Volvo Automobile and Truck companies. This achievement, as the final contribution to the Swedish automotive industry after having already treated this research field/problem area for more than two decades before this particular period if time (involving several junior and senior research competencies, as well as industrial and governmental foundings). A comment: As 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).

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Consumer report for the company in question which is financed by the company, and carried out in cooperation with the Department Industrial Planning at the School of Architecture at Chalmers University of Technology. This effort, in turn, gave birth to some further years of cooperation with the company engaging researchers from Chalmers.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Consumer report for the company in question (the Volvo Automobile Company) which was financed by the company and partly also by a research foundation. It is a matter of a work that in this particular case were carried out during nine years in a number of experimental workshops located outside the Chalmers University of Technology. This report has been validated by Volvo expertise at the Volo Torslanda plant (the content in this report represent extensive work from the author's side). These workshops were financed by the Volvo Automobile and Truck companies. This achievement, as the final contribution to the Swedish automotive industry after having already treated this research field/problem area for more than two decades before this particular period if time (involving several junior and senior research competencies, as well as industrial and governmental foundings). Specifically, this publication explains in one particular perspective how the authors dealt with the product architecture and product variation of the automotive products disassembled, which proved to necessary to be carried out in one of the experimental workshops (FOOTNOTE 1). Besides of making the product architecture and product variation understandable for the parties involved (operators as well as practitioners), was the functions of the automotive products just as important to grasp. Especially so with regard to if such (product) functions was something that was or gradually become evident during the assembly work, or alternatively if this was impossible to understand. In the latter case, such as chassis settings (that eventually to some extent would be possible to grasp), or many marketed-oriented codes (that are extremely difficult to decode) (several complete automobiles and one heavy truck chassis were disassembled combined with having product data accessible in form of paper print-outs as well as by appropriate computer connections to the two Volvo companies etc. as well as other publication that dealt with automotive matters from the Volvo or from other sources). FOOTNOTE 1: See a conference contribution from 1992 that also is registered and available as o PDF-document at Chalmers Public Library (CPL) (a self-developed method found out together with a junior research competency from the School of Architecture at Chalmers).

Fundamental principles of ultrafiltration
- 1990
-
Ingår i: Chemical Engineering and Processing. - 0255-2701. ; 27:2, s. 67-81
-
Tidskriftsartikel (refereegranskat)abstract
- Different theoretical models describing the influence of the operating parameters are treated in this paper. The osmotic pressure, gel layer and resistance in series models are presented. The influence of different operating parameters, such as the operating pressure, temperature, cross-flow velocity and concentration is demonstrated. The complex fouling phenomenon is reviewed. Finally, various pretreatment and cleaning operations are presented.
