| Summary: | 碩士 === 中原大學 === 工業工程研究所 === 102 === One of the foremost difficulties in remanufacturing is the uncertainty of return rate which directly influences the profit-making of companies. Hence, for remanufacturing to acquire huge prosperity, there is an indispensable prerequisite to precisely strategize the production quantity as much as possible. This paper proposes two models throughout the remanufacturing process of computer accessories, which is composed of (1) prior to the arrival of products, a stochastic return rate is used for initially setting up the layout, equipment, and manpower; and (2) after the used products have arrived, the quantity of each used product is known for production plan in each period. In these models, pure remanufacturing and decentralized input setting are applied by considering the product life cycle. Simultaneously, a theoretical definition and framework of remanufacturing are offered to have a more general view in this study. Examples are provided for illustrating the proposed models and are run on the AIMMS software. In addition, some parameters such as optimum quantity, inventory stock, production cost, setup cost, and inventory cost which are the major influencing characteristics to total profit are examined. We believe that using these models in remanufacturing, the operations in companies will be smoother and more profitable.
