An optimization concept for business data-processing equipment
D. R. Swanson · 1955
It is demonstrated that under certain conditions there exists an optimal relationship, based on cost and performance, between the number of magnetic tape units and the number of digital computers in a business data-processing system. The relationship is derived in such a form as to indicate how the concept might be generally applied to any kind of system. Some discussion is also given on the question of random access in business data processing.
