Modeling of a Probabilistic Re-Entrant Line Bounded by Limited Operation Utilization Time

Stochastic re-entrant line modeling for an environment stress testing in a semiconductor assembly industry

Environmental stress testing (EST) is a reliability test for the semiconductor products that is concerned with how products perform its intended functions under some environmental conditions. Planning, implementation and delivery schedules are affected by the outcome of these tests and it is crucial to determine the throughput of the EST process. In this paper we present an efficient modified a...

An Artificial Neural Network Approach – Performance Measure of a Re-entrant Line in a Reflow Screening Operation

This paper presents an artificial neural network (ANN) method applied to a multistage re-entrant line system. Generally, queuing networks adopt analytical methods or use simulation packages to determine their performance measure. The contribution of this paper is the development of an alternate solution method using ANN approach to determine performance measure namely the total cycle time for a...

A 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...

Modeling and Analysis of Re-entrant Production Systems

This paper presents a model and analysis of a reentrant production line with finite buffers and unreliable machines. Semiconductor device and liquid crystal display (LCD) fabrication processes are characterized as a re-entrant process, in which a similar sequence of processing step is repeated several times. The purpose of this paper is to present mathematical formulations and algorithms to ana...
