The background for this history is the comprehensive renewal of concepts and solutions in connection with the rebuilding of Burmeister & Wain’s shipyard at Refshaleøen in Copenhagen 1957–61. The project was started before access to digital computers was normal, but the parallel development of the first Danish computer DASK added new possibilities for planning and control of a more complex, but consistent production flow. The basis for this paper is the author’s experience and personal files from participation in the project.
