不同决策模式下农产品质量控制策略研究

Research into Quality Control Strategy of Fresh Agricultural Products under Different Decision Modes

农产品质量已经引起公众的广泛关注。考虑由一个供应商和一个零售商构成的两级农产品供应链,构建零售商主导下的Stackelberg分散决策博弈模型和两者协同合作下的集中决策博弈模型,以供应商和零售商的最优质量努力水平为状态变量,利用逆向求解法得出供应商和零售商的最优质量决策。研究表明:在一定条件下,农产品供应链中主体的合作可以实现供应商、零售商和整个供应链系统利润的Pareto改善,在此基础上分析实现Pareto改善的条件以推动农产品供应链达到协调。

Quality of agricultural products catches the eye of the public.This paper considers two levels of supply chain including a supplier and a retailer to establish two kinds of differential game models: Stackelberg game model led by retailers and the game model under subject cooperation.Optimal quality effort level is considered as state variable and optimization decision of supplier and retailer can be solved using the method of feedback.The results show that under certain conditions subject cooperation can achieve Pareto improvement of suppliers,retailers and the entire supply chain system profit.The conditions of achieving Pareto are analyzed to promote the coordination of the fresh agricultural product supply chain on the basis of above research.
