Abstract

A new queuing model (HE3/HE3/S):(PRP/∞/∞), in which both the interarrival times and the service times follow the hyperexponential distributions with three branches, has been justified for a machine maintenance problem.Analysis of the problem is based on the data obtained from a large and complex manufacturing system. The GPSS model is constructed so that it collects desired queuing statistics under alternative conditions of a different number of servers. The essential purpose of this study is to model a priority queuing problem with multi-servers. The GPSS design can apply to waiting line problems where random variables of interest have large variations.
