双回收模式下闭环供应链信息分享问题研究

研究制造商和零售商同时对废旧产品进行回收的双回收模式下闭环供应链中零售商的需求预测信息分享问题。建立信息分享与信息不分享下产品定价和回收努力决策模型,比较均衡解,并通过数值算例分析回收竞争强度、价格弹性系数等参数对均衡解和期望信息分享值的影响。研究表明:双回收模式下闭环供应链中信息分享使得整个供应链的期望利润减少,并不能提高系统的绩效。

Information sharing in a closed-loop supply chain under dual-recycling mode

The problem of demand forecasting information sharing is studied among retailers in closed-loop supply chain under the dual-recycling mode in which both manufacturers and retailers recycle waste products simultaneously. The decision-making models of product pricing and recycling effort are established under information sharing and non-sharing. The equilibrium solutions are compared, and the effects of recycling competition intensity and price elasticity coefficient on equilibrium solutions and expected information sharing values are analyzed through the numerical examples. The results show that the information sharing in the closed-loop supply chain can reduce the expected profit of the whole supply chain, but cannot improve the performance of the system.
