Simulation of computer program distribution

摘要

A computer program library is essentially a "job shop" which accepts and processes requests for computer programs. Such processing usually results in an initial delivery of the program package to the requestor, followed later by deliveries of maintenance packages to him.

rn

Packages usually consist of documentation and machine readable material (cards, tapes, disks, etc.).The latter is prepared on data processing equipment installed in the shop.

rn

Simulation of this preparation process has proved to be a useful tool in the short and long range planning of the shop's facilities.

rn

The GPSS/360 model constructed simulates both the management's supervisory decision process as well as the resulting activity of machine readable material preparation. It produces a suggested equipment installation schedule, accompanied by statistics on equipment utilization, service times, costs, etc. based on that schedule.
