两零售商竞争下第三方回收闭环供应链的决策及协调

为研究同时考虑零售商竞争与第三方回收闭环供应链的定价决策及协调问题, 分别建立了集中与分散决策模式下的闭环供应链优化模型, 并提出了基于改进K-S法的协调机制。研究表明:在分散式闭环供应链决策下, 较之两零售商与第三方, 制造商总是可以获得最大的利润。两零售商在产品价格上竞争程度的增强不仅可以有效提高产品销量, 同时对废旧产品的回收也起到了很好地促进作用。闭环供应链成员企业间的合作策略能有效消除系统的“双重边际”效应, 且较之零售商及第三方回收商, 制造商的合作动力更强。

Decision and Coordination for Third-party Collecting Closed-loopSupply Chain with Two Competing Retailers

In order to study the pricing decision and coordination problems of closed-oop supply chain(CLSC)with two competing retailers and a third-party collector,the optimization models of CLSC are constructed under centralized and decentralized systems respectively,and a coordination mechanism based on improved K-S method is established.The results show that:the manufacturer always receives more channel profits than the two retailers and the third-party collector under decentralized decision.The enhancement of competition between the two retailers in product price can not only effectively increase product sales,but also promote the recycling of waste products.The channel member’s cooperative strategies can effectively avoid the“double marginal”effect of CLSC systems,and the manufacturer has more incentive to cooperate compared with the two retailers and third-party collector.
