风险规避对闭环供应链决策的影响

Effect of Risk Aversion on Decision of Closed-Loop Supply Chain

构建了3种不同回收渠道(制造商回收、零售商回收和第三方回收商回收)下的闭环供应链模型,以制造商为Stackelber领导者,分析了分散化决策下的3种最优决策模型,考察了闭环供应链各参与方的风险规避程度对其定价决策和期望利润的影响,并借助数值分析对求解结果进行了验证。研究结果表明:随着风险规避程度的增大,零售商趋向于降低零售价格,回收方趋向于提高回收价格;在其他因素不变的情况下,闭环供应链各参与方的风险规避程度增大往往会导致其期望利润减少。

The closed-loop supply chain models under three different collecting channels（manufacturer collecting, retailer collecting,third-party collecting） are constructed. Three optimal decision models as decentralized decision-making systems with the manufacturer being the Stackelberg leader aer analyzed. The impacts of risk aversion on pricing decisions and expected profits of participants in closed-loop supply chain are discussed. Finally, the results of three models are verified through the numerical analysis. The results show as follows：with the increasing of risk aversion,the retailer tends to reduce retail price and the collecting parties tend to increase collecting price;in the case of other factors constant, with the increasing of the participants＇ risk aversion,the expected profit often leads to decline.
