Abstract

Material flow in a semiconductor manufacturing system has the marked property of reentrancy. This property leads to interesting problems of machine scheduling. This property also introduces the non-product-form features into the corresponding queueing model of the semiconductor manufacturing system, and thus making it extremely difficult to exactly analyze the model, and evaluate the performance of the system. In this paper we present an efficient analytical technique for predicting the performance of a semiconductor manufacturing system, employing any fixed buffer machine scheduling policy. The method is based on mean value analysis, a well known queueing theory based technique for analyzing queueing networks. Compositionally the method is overwhelmingly efficient compared simulation. The method also facilitates explicit modeling of scheduling policies used in multiclass manufacturing systems.
