碩士 / 明新科技大學 / 工程管理研究所 / 93 / Reverse Logistics is a new concept that deals with the management of the products in the reverse way, i.e., it is the process of managing all the flow of returned products and information from the point of consumption to the origin. The actual development of reverse logistics strategies in many companies across the world makes it a very interesting topic to work with. It is expected that in few years it will be a
crucial element in determining the way in which products will be designed, produced and distributed. The magnitude and impact of reverse logistics varies with industry, channel position and channel choice. However, it is clear that the overall amount of
reverse logistics activities in the economy is large and still growing. In this paper we consider a reverse logistics system with manufacturing, remanufacturing, and disposal operations. Customer demands must be fulfilled from serviceable stock which has two sources: the remanufacturing of base items or manufacturing of new items. Used items are either put into base item stock or disposed of. To coordinate manufacturing, remanufacturing, and disposal operations efficiently, the PUSH and PULL strategies are used for inventory control. This study proposes a research structure to evaluate the impact of inventory policies and decision variables (including remanufacturing and manufacturing related variables, order related variables, and cost related variables) on system performance in the reverse logistics system with multiple products. Of the two inventory policies, the preferences are investigated with respect to different performance indexes. An example is used to demonstrate the research structure. Based
on the results of the example, order quantity homogeneity (OQH) has a major impact on system performance with respect to all performance indexes. Furthermore, the PULL policy is recommended if the inventory level of serviceable items is used as the major performance index. The PUSH policy is recommended if the service level or the inventory level of base items is used as the major performance index.
