碩士 === 輔仁大學 === 資訊管理學系 === 90 === Master production scheduling plays a role as the heart of a modern business. It inputs the production problems, such as committed and uncommitted PO, forecasting, product line capability, quality problems, key parts stocks, etc., and outputs the plans and schedules. This drives all the related business processes such as purchasing materials, producing products, dispatching jobs, …and so on. In this research, we investigate the related production activities and idenfy the problems in an electronic company. An APS model that fits in the case company is proposed. With 6 scenario testing, we verify the APS model to be suitable for the case company. This model uses linear programming and TOC (Theory of Constraints) as the engine of scheduling. This APS model considers the constraints of capacity and its objective is to minimize the total cost. We also find an interesting phenomenon (we name it “The Eclipsed Moon phenomenon”), which can be used to determine if a business should employee an APS system or do the scheduling manually.
