Abstract : In support of a request from the Air Force Logistics Command, a model of the Advanced Logistics System (ALS) CYBER 73 Batch processing system was developed. The initial specification required that this model allow changes to the magnetic tape unit configuration and to all essential installation parameters. In order to determine the best approach, the various computer system modeling techniques are first surveyed. Then, based on the modeling goals and requirements, a queue level simulation model is selected as the best approach. The basic features of the CYBER 73 computer system are discussed and a description of job movement through the system is given. This discussion is used to describe the various system queues and the SCOPE integrated scheduler. The algorithms used in the model are then developed and the accuracy of the model verified by comparison against data obtained from the ALS CYBER 73 batch system during test runs of a typical jobmix. The verification process showed that all of the original design objectives were met, although several areas of possible improvement to the model are indicated and discussed.
