A deterministic inventory model with constant demand and return on the base of economic order quantity (EOQ) is considered. We consider a firm that can manufacture new products and recover the value of a used product through remanufacturing with dismantling for components. The firm provides product at a constant demand rate. Product consists of two components. Each part is manufactured separately and placed in inventory, then two components are assembled. The dismantling operation yields two spare components. Products are returned according to the return rate, other products are disposed of. The returned product is dismantled for components, any part is inspected whether it is usable or not and then is placed in inventory. Both components are usable at the different rate. The usable components are then remanufactured or directly reused, other components are disposed of.
