退货约束下供应商主导调拨的订货与定价模型

Ordering and pricing model of supplier-dominated transshipment with return constraints

针对调拨过程中供应链成员之间可能会由于缺乏信任以及信息不对称等因素导致调拨策略失效问题,建立了零售商有条件退货情形下供应商主导的调拨模型.证明了零售商订货纳什均衡的存在性和惟一性,构建了订货量与批发价格和调拨价格的关系.在此基础上,分析了最优调拨价格与退货率的关系,并在一定条件下得到了最优调拨价格.然后,进一步分析了调拨价格和批发价格等与退货率的关系.结果表明,零售商有条件退货情形下供应商主导的调拨实施后,供应商的利润得到提高,零售商的利润是否提高取决于退货率的大小,供应链的整体效率得到改善.

Retailers often fail to implement transshipment policy due to the lack of trust or asymmetric infor- mation among them in the process of transshipment. Considering this, a model of supplier-dominated trans- shipment with retailer returning conditionally is developed. The unique existence and uniqueness of ordering Nash equilibrium is proved. In addition, the relationship between the ordering quantities and the wholesale price and transshipment price is also analyzed. Based on this analysis, the paper studies the relationship be- tween the transshipment price and return rate, and obtains the optimal transshipment price in some conditions. Finally, the relationship between the transshipment price, the wholesale price, ordering quantities, the profit of retailers, the profit of suppliers and the efficiency of the supply chain and return rate is further analyzed. The results show that the supplier always benefits from transshipment, whether the retailer＇s profit can be improved or not depends on the return rate, and the efficiency of the supply chain can be improved by implementing supplier-dominated transshipment policy under retailer returning conditionally.
