摘要
为研究零售商风险规避背景下的双渠道供应链网络均衡问题,构建了一个包含多个竞争性供应商、制造商、零售商及需求市场的双渠道供应链网络均衡模型。采用均值-CVaR法量化网络中零售商的风险规避特征,运用变分不等式表征供应链各层级主体的均衡条件。利用投影收缩算法进行模型求解和算例分析,揭示零售商风险规避行为对均衡结果的影响。仿真结果表明:零售商越规避风险,供应链网络成员的整体利润或效用水平越高;零售商自身更倾向于关注期望利润,而网络其他成员则期望其更关注CVaR利润;零售商的风险规避行为会影响需求市场对不同销售渠道的偏好选择。为双渠道供应链网络优化生产定价决策以及管理需求不确定性风险提供理论依据。
To study the network equilibrium problem of dual-channel supply chains under the background of retailers'risk aversion,a dual-channel supply chain network equilibrium model including multiple competitive suppliers,manufacturers,retailers,and demand markets was established.The Mean-CVaR method was employed to quantify retailers'risk aversion characteristics,and variational inequalities were utilized to characterize the equilibrium conditions of decision-makers at each tier of the supply chain.The projection contraction algorithm was applied to solve the model and conduct numerical analysis,thereby revealing the impact of retailers'risk aversion behavior on equilibrium outcomes.The simulation results indicate that a higher degree of risk aversion among retailers enhances the overall profit or utility levels of supply chain network members.While retailers tend to prioritize expected profit,other network participants prefer them to focus more on CVaR-based profit.Furthermore,retailers'risk aversion behavior significantly influences demand markets'channel selection preferences.The results provide a theoretical basis for optimizing production and pricing decisions and managing demand uncertainty risks in dual-channel supply chain networks.
