Abstract: To analyze the effect of customer returns on retailer's inventory system, a retailer's optimal ordering decision model, a retailer's noncooperative game model with inventory competition and a transshipment game model between two locations were constructed. The analytical form of optimal ordering was given, and the influence of customer returns on retailer's optimal ordering as well as expected profit was verified. The analytical form of pure Nash equilibrium strategy's evidence theory and equilibrium ordering in inventory competition game was given. The pure Nash equilibrium strategy's existing basis and sufficient condition of existence and uniqueness in transshipment game model was derived, and analytical form of Nash equilibrium ordering was given. The intercomparsion relationship of retailer's optimal order quantity under three conditions was analyzed, and the evidence theory that regulating retailer inventory by transshipment prices was obtained. Thus, the reasonable setting for transshipment price could coordinate retailer's lateral transshipment and allocate system total expected profits effectively. Based on these conclusions, the effect of customer returns on retailer's expected profits was analyzed emphatically by numerical examples. The results demonstrated that the influence of customer returns for retailers was deteriorated because of inventory competition, but lateral transshipment could weaken the influence of customer returns for retailers.
