考虑运输时间和消费者偏好的水产品供应链协调研究

Research on Aquatic Product Supply Chain Coordination Considering Transport Time and Consumer Preference

本文研究了由一个供应商和一个零售商组成的两级生鲜品供应链协调问题。考虑消费者水产品生鲜偏好、运输时间和保鲜努力水平等影响因素,分别构建了集中决策和分散决策下冷链保鲜存储的零售商和供应商的供应链成员之间Stackelberg博弈模型。通过理论证明和数值仿真的研究表明,在“保鲜成本分担+收益共享”契约,供应链总体利润大于一般保鲜成本共担契约,能获得更高的利润,“保鲜成本分担+收益共享”契约更能提高冷链储存的保鲜努力水平。

This paper studies the coordination problem of two levels of fresh produce supply chain composed of supply chain member.We take into account such factors as consumers’preference for fresh aquatic products,time of transportation,and level of preservation efforts.A Stackelberg game model between retailer and supplier’s supply chain members under integrated decision and dispersed decision is structured.The theoretical demonstration and numerical simulation indicate that the overall profit of the supply chain is greater than the common retaining freshness cost-recovery policy contract,and the retaining freshness cost-recovery policy&benefit-sharing contract can increase the retaining freshness efforts of cold chain store.
