基于数量损耗的生鲜电商供应链协调研究

Research on Supply Chain Coordination of Fresh E-commerce Considering Quantity Loss

针对单一生鲜供应商和单一生鲜电商组成的二级供应链,通过Stackberg博弈模型和供应链契约理论分析3种模式下的供应链最优收益、生鲜农产品采购数量、生鲜电商单位农产品销售价格、生鲜电商自营物流服务水平。结果表明:生鲜损耗率在一定区间时,协调后的供应链利润总大于协调前;契约参数满足一定条件时,“收益共享+成本共担”的混合契约可以协调生鲜电商供应链,实现双方的帕累托改进。

Aiming at the two-level supply chain composed of a single fresh supplier and a single fresh electricity supplier,this paper analyzes the optimal supply chain revenue,fresh agricultural product purchase quantity,fresh agricultural product sales price of fresh electricity supplier and fresh electricity supplier's self-service logistics service level under the three modes by means of Stackberg game model and supply chain contract theory.The results show that when the fresh loss rate is in a certain range,the profit of the supply chain after coordination is always greater than that before coordination.When the contract parameters meet certain conditions,the hybrid contract of“revenue sharing+cost sharing”can coordinate the fresh e-commerce supply chain and realize the Pareto improvement of both sides.
