“…Cardenas-CardenasBarron [2] where an error appearing on Salameh and Jaber [31] was corrected. Thereafter, Chan et al [3] proposed a non-shortage model similar to that in Salameh and Jaber [31], where products are classified as good quality, good quality after alternative, defective value and piece. Rosenblatt and Lee [30] suppose that the elapsed time until the production process shift is a random variable and is exponentially distributed, and derive an approximated optimal production run time in their models.…”

This paper develops an economic production quantity (EPQ) inventory model with rework process for a single stage production system with one machine. The existence of a unique machine results in limited production capacity. The aim of this research is to determine both the optimal cycle length and the optimal production quantity for each product to minimize the expected total cost (holding, production, setup, rework costs). The convexity of the inventory model is derived. Also the objective function is proved to be convex. The proposed inventory model is validated with illustrating numerical examples and the optimal period length and the total system cost are analyzed.

“…Salameh and Jaber [35] considered an EPQ model wherein defective products are discovered during inspection and, then, sold at discounted prices in the secondary markets. Chan et al [36] incorporated product inspection of all goods into an EPQ model, wherein defective goods are treated by selling them at discounted prices, reworking them, or rejecting them. Chiu [37] developed an EPQ model that considered shortages, and assumed that randomly produced defective products were reworked or discarded.…”

Abstract. This study investigated a production-inventory model with defective items under a two-part trade credit, where the agreement of conditionally freight concession is considered in an integrated supply chain. It is assumed here that the retailer conducts the inspection process before selling incoming items. All the defective items are discovered, stored, and sold as a single batch to a secondary market at a decreased price. Furthermore, shortages are allowed and completely backlogged for the retailer. The purpose of this study is to determine the optimal number of shipments per production cycle for the supplier and the optimal length of time when there is no inventory shortage and replenishment cycle for the retailer, such that the total pro t function has a maximum value. In theoretical analysis, the existence and uniqueness of the optimal solutions are shown, and an algorithm is developed to nd the optimal solutions. Furthermore, numerical examples are presented to demonstrate the solution procedures, and a sensitivity analysis of the optimal solutions regarding all parameters is also carried out.
