Simulation for planning and scheduling

摘要

This paper discusses a simulation approach to production planning and scheduling utilized at Raytheon's Missile Systems Plant in Andover, Mass.* A GPSS model and computer program has been developed to simulate the production of some 35,000 printed wiring assemblies. There are a number of different types of assemblies, each of which follows a fixed sequence of operations performed at different work stations. This situation results in a large-scale queuing problem which must be solved by a dynamic technique like simulation. The output from the simulation is currently being used to determine lot size, manpower requirements and production schedules.
