随机需求和奖惩机制下的闭环供应链决策模型

研究新产品和再制造产品需求均为不确定下的闭环供应链系统。通过比较两种产品的消费者WTP(willing to pay)差异性,构建三种政府奖惩机制条件下的闭环供应链模型。深入分析不同制造商主导的博弈模型及其数值实验。结果表明:无论是基于回收率还是回收量的政府奖惩机制,第三方回收模式下回收率最高,制造商利润最高,制造商回收模式下零售商利润最高;消费者对再制造产品WTP差异增加时,制造商利润、零售商利润及渠道总利润先减少后增加;政府奖惩机制变化时,第三方回收模式的回收率随政府奖惩的增加而增幅最大。

Decision model of closed-loop supply chain under stochasticdemand and premium-penalty mechanism

The closed-loop supply chain system based on stochastic demand of new product and remanufactured products have been researched. This paper compared the WTP differentiation of retail to two products, and structured three classes closed-loop supply chain models based on premium and penalty mechanism of government. When manufacturer was the leader of the game, and deep analyzed numerical example. The results show that, based on both collection rate and collection quantity of premium and penalty mechanism, the collection rate and manufacturer's profit are highest in third-party recycling mode and retailer's profit are highest in manufacturer recycling mode; the profit of manufacturer, retailer and total profit first decrease and then increase with the WTP otherness of remanufactured products increased. Increment of collection rate under third-party recycling are highest increase with premium and penalty mechanism of government.
