零售商竞争下三级闭环供应链利润共享契约模型研究

Research on Profit-Sharing Contract Model in Triple Closed-loop Supply Chain under Retail Competition

基于零售商产品销售价格竞争环境,并考虑零售商废旧品回收过程,文章研究了两零售商、分销商和制造商组成的三级闭环供应链的协调过程。通过对分散决策和集中决策时供应链各成员及整条链的利润分析,设计了零售商价格竞争下三级闭环供应链利润共享契约协调模型,在合理的利润分配系数下,供应链各节点可以实现最优。最后,通过算例分析验证了模型的科学性和合理性。

Based on the competition environment of retailers product sales price, considering the recycling process of retailers waste product, the coordination process of triple closed-loop supply chain is studied ,which is composed by the two retailers, distributor and manufacturer. Through the profit analysis of the supply chain members and the whole chain on the decentralized and centralized de- cision, designing the profit-sharing contract coordination model of triple closed-loop supply chain under the competition of retailer price, the node enterprises in the supply chain can realize the optimal under the reasonable profit distribution coefficient. Finally, the example is used to verify the model which is scientific and feasible.
