考虑风险与资金约束的闭环供应链定价与回收决策

针对回收商资金约束的闭环供应链，考虑成员面对需求不确定时表现出不同风险态度，研究闭环供应链的定价与回收决策问题.通过均值-方差法刻画闭环供应链各成员的风险态度，分别给出集中决策和分散决策下的最优批发价格、零售价格和回收率，分析各成员的风险态度、贷款利率和需求不确定性对最优决策以及成员和闭环供应链效用的影响.研究表明:风险中性的回收商对供应链成员均有利，风险中性的零售商和制造商只对自身有利；贷款利率的增加会降低供应链成员的效用；较低的需求不确定性对零售商、回收商和分散决策下的闭环供应链有利.

Pricing and Recycling Decision of Closed-Loop Supply Chains Considering Risks and Capital Constraints

Based on a closed-loop supply chain with recycler capital constraints， the pricing and recycling decision of closed-loop supply chains is studied considering participators’ risk attitudes faced with stochastic demands. The risk attitudes of participators are described based on mean-variance. The optimal wholesale price， retail price and recycling rate in centralized and decentralized decisions are determined respectively. Then the impacts of risk attitudes of participators， loan interest rates and demand uncertainty on the optimal strategies and the utility of members and closed-loop supply chains are analyzed. The results show that the recyclers of risk neutrality is beneficial to all participators， while the retailers and manufacturers of risk neutrality are only beneficial to themselves. The increase of loan interest rates will reduce the utility of participators， while lower demand uncertainty is beneficial to the retailers， recyclers and closed-loop supply chains in decentralized decisions.
