The Effects of Machine Load Sitnations on Performance of Job Shop and Group Scheduling

Abstract

Perfonnance of job shop and group scheduling ndermulti­natch work input environment was exarnined against two nachine load (light and high load) situations. n order to conduct the analysis, a deterministic computer ;im ulation program was written and used. A job shop {JS) model is applied to the shop floor area and :ompared with a simulation of a similar proposal except hat group technology (GT) model was used in the shop loor area instead. )etailed analysis of the results from applying different nachine load sitnations and different models were ssessed according to the performance criteria of order ardiness, work-in-progress and machine utilisation.
