基于收益共享契约的网购供应链ITIO的演化博弈分析

Evolutionary ITIO Analysis of Supply Chain on Online Shopping under Revenue Sharing Contract

本文以收益共享契约为切入点,建立有限理性条件下的网购供应链ITIO演化博弈模型,分别求出联合优化和不联合优化时网商和3PL的利润函数,构建各参与方的复制动态方程,并根据ITIO策略采用比例的动态变化趋势和稳定性,画出其相位图,最后得出供应链库存与运输联合优化的结论。研究结果表明,有限理性的网商和3PL是否会采用联合优化演化稳定策略,取决于联合优化的利润分配比例,网商应制定出合理的联合优化利润分配策略,以实现网商和3PL整体最优。

This paper set up evolutionary ITIO model of supply chain on online shopping under the condition of limited rationality,based on revenue sharing contract,respectively obtained the profit function of e-businessman and 3PL under the joint optimization and no joint optimization,constructed replicated dynamic equation of each parties,and based on the dynamic change trend of ITIO strategy using ratio and stability,draw the phase diagram.Finally it made the conclusion of joint optimization strategy of supply chain inventory and transportation.Research results show whether the bounded rationality of electronic retailing and 3PL would adopt combination optimization evolutionary stable strategy,depends on the joint optimization of profit distribution proportion.Electronic retailing suppliers should formulate reasonable joint optimization of profit allocation strategy,in order to realize electronic retailing and 3PLoverall optimal.
