摘要

  The witness seminar ”Styrbjörn: Utvecklingen och användningen av ett konstruktions- och produktionssystem för skeppsbyggnad vid Kockums under 1960- och 1970-talen” [Styrbjörn: The Development and Use of a System for Construction and Production in Ship-Building at Kockums during the 1960s and 1970s] was held at AVEVA AB in Malmö on 2 October 2007 and was led by Tomas Ohlin. It dealt with the development, use, and diffusion of Styrbjörn, a computer-based system for construction and production in ship-building developed by the shipyard Kockums during the 1960s and the 1970s. Originally, Styrbjörn was a numerical system for construction of body details, but soon developed into an integrated system for both construction and production of ships. At the seminar, the cooperation between Kockums and Saab was highlighted. Kockums used the Saab manufactured computer D21 as well as the programming language ALGOLGENIUS created at Saab. Together the two companies developed KOCK, a derivative of ALGOL-GENIUS specially designed for ship-building. When the Saab computers disappeared from the market in the beginning of the 1970s, Styrbjörn was rewritten to the programming language PL/I and was thus made compatible with IBM computers. Also discussed during the seminar was the transition from main frame computers to mini computers during the 1970s and the beginning of 1980s and the implications this shift had for Styrbjörn.
