本文研究了在不确定需求条件下由多个相互竞争的制造商、零售商和消费市场组成供应链网络均衡问题。由于需求的不确定性,零售商会对当前利润和供需平衡时的最大利润进行对比,从而产生后悔或欣喜的心理。基于后悔理论,建立了零售商利润最大化、后悔值最小最大化的多准则均衡模型,且通过变分不等式理论得到网络各级决策者的均衡条件和整个供应链网络的均衡条件。最后通过数值算例分析决策者的后悔心理对网络各决策者最优订购量、最优利润值、后悔值的影响。
This paper studies the equilibrium of supply chain networks with multiple competing manufacturers, retailers and consumer markets under the condition of uncertain demand. Due to the uncertainty of demand, the retailer will compare the current profit with the maximum profit at the balance of supply and demand, resulting in regret or delight. Based on the regret theory, a multi-criteria equilibrium model of retailer’s profit maximization and regret value minimization maximization is established, and the equilibrium conditions of decision makers at all levels and the equilibrium conditions of the entire supply chain network are obtained by using the theory of variational inequality. Finally, numerical examples are used to analyze the influence of decision makers’ regret mentality on the optimal order quantity, the optimal profit value and the regret value of the network decision makers.
