| Summary: | 碩士 === 國立中央大學 === 工業管理研究所 === 102 === With the release of the new electronic products, people replace their electronics more often. Although it brings a lot of profit for companies, it also accumulates a lot of e-waste because the new electronic products has substituted for the old one. While enterprises are growing fastly, based on environmental protection and social responsibility, enterprises should devote to new product design or dealing with the end-of-life products. Therefore, many companies provide the recycling services for the end-of-life products to recycle and disassemble the products and the parts can be used again. However, for the products such as electronics which have short life cycle, many products have substitute by new ones although it can be used normally. But it's wasteful if we recycling and disassembling this kind of product. Thus, this thesis will pick out the valuable end-of-life products to refurbish to sale, and the worthless products will be used by manufacturers after they were disassembled into parts.
This thesis studies the end-of-life computers in Taiwan, and using mixed integer programming model to solve the problem in consideration of the transport costs, products and parts opened costs, and production capacity limit. According to this research, it's valuable to open refurbishing and sale processes in certain situations. First, capacity of disassembling center is limited. Second, parts supply more than demand. Third, there's no demand of manufacturer for certain parts. In above situations, refurbishing and sale processes can reduce total cost effectively. Furthermore, we can also analyze other products such as smart phone as long as we have enough data.
