| Summary: | 碩士 === 國立中央大學 === 工業管理研究所 === 103 === High technology produce the electronic products sooner. Products’ life cycle become shorter and come over more wasted problems. In this situation, reverse logistic becomes an important part in supply chain. How to let recycling useful in cost and time aspects becomes a valuable question. Automatic control electronic devices are the stable embedded system products. Because of the products have long life cycle and the materials are high level stable, products can be valuable in recycling.
This thesis researches the repair policy of automatic control electronic devices, and uses linear programming model to develop the minimize cost in consideration of repair cost, inventory cost and additional working cost. The recycling constrains are including repair capacity and inventory capacity. Furthermore, the thesis also analyzes the warranty cost from each used year. For the best decision in scenario analysis 1 is extended the four years warranty. And for the best decision in scenario analysis 2 is to reduce 10 percentages. Both analyses can get the highest profit.
