Abstract
Scheduling jobs in a machine shop is a complex problem that is intractable analytically. A detailed simulation model allows managers to try policies under realistic conditions without disrupting operations. Our model, written in GASP IV for a CDC 7600 computer, was produced from an in-depth study of the operations of a job shop. The model uses actual company data (approximately 1300 components) on individual machines and operators and incorporates double shifts, overtime, machine breakdown and absenteeism, limited batch splitting, alternate job routings, and stores. We validated the model by comparing its output with actual data. The model provides information on output, completion dates, cost per unit of output, and miscellaneous measures such as queue length and labor and machine utilization. An example application of the model shows the testing of various priority rules.
