A model for analyzing closed-loop conveyor systems with multiple work stations

摘要

This paper presents the modeling methodology incorporated in a GPSS/360 program to simulate and test the operation of a generalized recirculating conveyor-supplied system, consisting of loader, conveyor, and multiple work stations. Features of the generalized model include its ability to simulate a constant-speed closed-loop conveyor with discretely spaced random loads, variable spacing between work stations, variable supply and return distances, variable total length, zero or specifiably finite local storages at each work station, homogeneous service rates in the work stations, variable number of work stations, and choice of arrival (loading) distribution. Output statistics include many tabulated operating characteristics of the system.
