All rights reserved.Recently, an alternative multi-delivery policy into imperfect Economic Production Quantity (EPQ) inventory model with partial rework has been proposed, which considers the number of shipments as a fixed and given value. This paper, treating the longrun average costs per unit time as a function of replenishment lot size Q and the number of shipments n, adopts the differential calculus approach to get the optimal solution of Q and n jointly. In numerical examples, it is illustrated that the solution procedure is simple and accurate.
