碩士 === 國立臺灣大學 === 商學系 === 82 === Master Production Schedule is an effective tool which can make high efficiency of manufacturing and high level of service at the same time for companies. An efficient master production schedule is resulted from the decisions which are designed originally. These decisions are named as MPS policies, including (1)methods of MPS, (2)master scheduling items (3) planning horizon, (4)time fence, (5)time bucket, (6)replanning interval, (7)safety stock, (8)safety time, (9)lot-sizing rule. The main goal of this paper is to discover the critical factors that affect the MPS policies for the factories in Taiwan and to discuss the reaction of each policy that caused by the critical factors. The results of this paper demonstrate that the critical factors could be classified as follows: 1.Product Factors: including (1)product profile, (2) standardiz- ing or customerlizing of products, (3)the cost of products. (4)purchasing leadtime, (5)fabrication leadtime, (6)assembling leadtime. 2.Manufacturing Factors: including (1)MPS changing cost, (2) service cost, (3) setup cost, (4)planning horizon, (5)replann- ing interval. 3.Environmental Factors: including (1)delivery leadtime, (2) volume of demand, (3) demand pattern, (4)distance of time. 4.Company Policy Factors: including the inventory policy. And in this paper, we also discuss the influences of every factors to the MPS Policies. This paper is an exploring research and its main goal is to find out of the questions, establish the hypothesis, and create continuously research of related questions. Therefore, at the end of this paper. there are seven hypothesis which could be demonstrated by the following research. And relevant suggestions and discussions are given to conclude the findings.
