Abstract
Most manufacturing systems have to face multiple sources of product demands. In this situation, tradeoffs between efficiency and flexibility are important decisions. Efficiency means that a manufacturing system can produce mass quantity of products on time with minimum production costs. Flexibility means that product variety is high in order to satisfy high level of customization. Product variety includes two main factors. One is the number of product types and the other is product mixes. In this work, the effects of product variety on the manufacturing system operation are studied. In this thesis, a stochastic and probability model for product mixes is first presented. It is then applied to three cases of production control of parallel machine systems: FCFS, time bucket, and batch queue. The efficiency loss is measured by the setup changeover. The relationship between variety and efficiency is then derived.
