零售商价格领导权结构下考虑专利保护的闭环供应链定价策略

Pricing Strategy of Closed-loop Supply Chain with Patent Protection under Retailer Price Leadership Structure

很多零售商常处于其所在供应链的主导地位,针对零售商具有价格领导权并且考虑专利保护的闭环供应链进行分析,运用博弈理论得到了零售商、原制造商和再制造商的最优策略,以及最优策略关于再制造成本节约的变化规律。研究表明:随着再制造成本节约的增加,最优单位专利许可费和废旧产品回收价格逐步增加,最优产品批发价格和销售价格逐步降低,并通过数值算例表明:零售商、再制造商和供应链系统的利润逐步增加,原制造商的利润逐步减少。

Many retailers are usually in the leading position of the supply chain. We study the closed-loop supply chain with patent protection in which the retailer has the price leadership, and obtain the optimal strategies of the retailer, the original manufacturer and the re-manufacturer using game theory, and the changing law of the opti- mal strategies with respect to the remanufacturing cost savings. The study indicates that as the remanufacturing cost savings increases, the optimal unit patent licensing fee and collection price of used products increase gradu- ally, and the optimal wholesale and sale price decrease gradually. Furthermore, we find the profit of the retailer, the re-manufacturer and the supply chain system all increase gradually, and the profit of the originally decreases gradually from the numerical example.
