【 摘 要 】

This paper integrates a cost reduction delivery policy into an imperfect production system with repairable items for the purpose of lowering producer’s stock holding cost. The present paper reexamines a manufacturing lot-size problem studied by a prior paper, and improves its production batch size solution in terms of lowering its inventory holding cost. Ann+1 delivery policy is proposed here in lieu ofnmulti-delivery plan used by the prior paper. Under such a policy, an initial (additional) installment of finished products is shipped to customer within the production uptime for satisfying product demand during producer’s regular production and rework times. Fixed quantityninstallments of finished items are then distributed to customer at a fixed interval of time, at the end of rework. Mathematical modeling and analyses are employed in this study. As a result, the optimal replenishment lot size solution is derived. A numerical example is provided to show its practical usage as well as its significant savings in stock holding cost.
