Multi-station manufacturing system analysis: theoretical and simulation study

This paper deals with a flexible multi-station manufacturing system modelled by re-entrant queueing model. Our model incorporates classical queueing systems with exponential service times and controlled arrival process under a priority service discipline. The system is decomposed into N 230 M. Boualem et al. fundamental multi-productive stations and 2N – 1 classes, a part follows the route fixed by the system, where each one is processed by N stations requiring 2N – 1 services. We assume that there is an infinite supply of work available, so that there are always parts ready for processing step 1. Our purpose in this paper is to present a detailed theoretical and simulation analysis of this priority multi-station manufacturing system.
