Abstract

This paper deals with the control of the production rates and setup actions of an unreliable multiple-machine, multiple-product manufacturing system. Each part type can be processed for a specified length of time on one of the involved machine. When switching the production from one type to another, each machine requires both setup time and setup cost. Our objective is to determine the production rates and a sequence of setups in order to minimize the total setup and surplus cost. Aiming the fact that an analytical or even a numerical solution of the problem is very difficult to find, a combined approach is presented. The proposed approach is based on stochastic optimal control theory, discrete event simulation, experimental design, and response surface methodology. We will prove experimentally that an extended version of the hedging corridor policy is more realistic and guarantees better performance for two cases of study. The first one consists on the unreliable one machine case facing exponential failure and repair time distribution. The second one, which is more complex and where the optimal control theory may not be easily used to obtain the optimal control policy, consists on five machines facing non exponential failure and repair time distributions. To illustrate the contribution of the paper and the robustness of the obtained control policy, numerical examples and sensitivity analysis are presented.
