Abstract
A Simulation Process was developed at the El Segundo Division of Hughes Aircraft company whereby actual shop operating data contained in an existing data processing system is used as input to an IBM 7090 computer for simulation of the El Segundo Fabrication Shop. The Simulation Process was used as a study tool to evaluate the effects of various management decisions on the operation of the Fabrication Shop. Management Technology, ISSN 0542-4917, was published as a separate journal from 1960 to 1964. In 1965 it was merged into Management Science.
