Abstract: Abstract In this paper, an inventory system with production, remanufacturing and refurbishing activities is studied, over a finite planning horizon. The demand is assumed time varying. Used products are returned by customers, and after inspection, they can be classified either as “remanufacturable” or as “refurbishable” items. The remanufacturing process brings “remanufacturable” items up to quality standards that are as rigorous as those of new items. The refurbished items are sold to a secondary market at a reduced price. In order to control the system, two types of policies are considered. For these two policies, a procedure is proposed that determines the order and remanufacturing quantities and the inventory level of returned (used) items at the start of the inspection and recovery processes, which minimize the total costs.
