碩士 === 國立中央大學 === 工業管理研究所 === 95 === In practice, manufacturers often produce their end products by a mix make-to-order (MTO) and make-to-stock (MTS) strategy. That is, manufacturers produce the products according to the orders arrival to satisfy customer’s demand of variety or keep products in advance to shorten the lead-time of demand. This mix production system could be use to produce for single end product that is assembled by many components. The problem of making decision for which sub-item to be MTO or MTS is important. In this study, we consider the above decision problem as determine a partition line in a bill of material (BOM) of the end product. Given a partition line in a BOM, we address the problem of determine the performance measure of this production system. We consider the light traffic heuristic proposed by Sigman and Simchi-Levi (1992) and busy period to derive the distribution of delay over all customers and inventory level distribution. We evaluate the accuracy of our model by comparing it to simulation results. We also conduct a numerical analysis to explore the effect of different parameter settings impact of various parameters on performance measures of this joint production system.
