Re-entrant Manufacturing Systems
Re-entrant manufacturing systems differ from traditional manufacturing systems in the sense that a job may visit a service station more than once, at various stages of the product development cycle. Several parts at different stages of processing may be in contention for service at the same machine, which gives rise to the need to solve scheduling problems. This document surveys some of the fac...
متن کاملA Scheduling Model for the Re-entrant Manufacturing System and Its Optimization by NSGA-II
In this study, a two-objective mixed-integer linear programming model (MILP) for multi-product re-entrant flow shop scheduling problem has been designed. As a result, two objectives are considered. One of them is maximization of the production rate and the other is the minimization of processing time. The system has m stations and can process several products in a moment. The re-entrant flow sho...
متن کاملScheduling Manufacturing Systems of Re{entrant Lines
Re{entrant lines are manufacturing systems where parts may return more than once to the same machine, for repeated stages of processing. Examples of such systems are semiconductor manufacturing plants. We consider the problems of scheduling such systems to reduce manufacturing lead times, variations in the manufacturing lead times, or holding costs. We assume a deterministic model, which allows...
متن کاملPeriodic Orbits in a Class of Re-Entrant Manufacturing Systems
Queue changes associated with each step of a manufacturing system are modeled by constant vector 6elds (8uid model of a queueing network). Observing these vector 6elds at 6xed events reduces them to a set of piecewise linear maps. It is proved that these maps show only periodic or eventually periodic orbits. An algorithm to determine the period of the orbits is presented. The dependence of the ...
متن کاملAnalysis of Control Mechanisms in a Re - entrant Manufacturing System
Modern semiconductor wafer fabrication facilities need to run at high levels of utilization in order to absorb the huge investments made in facilities and equipment. Simultaneously these facilities desire to minimize the cycle times of products in the factory for a variety of reasons including improved customer response, increased yield, and support of product development efforts. However, prob...
