Supply Chain Optimization Of Small And Medium-sized Enterprises Based On Evolutionary Game Model

In order to explore the income distribution of SME supply chain members under different dominant powers, this paper constructs an evolutionary game model to analyze the optimal decision of the three-level supply chain composed of product manufacturer, third-party logistics enterprise and retailer. The results show that the profit of supply chain under decentralized decision is lower than that under centralized decision. Therefore, by designing a revenue-sharing contract mechanism, the profit of supply chain is higher than that of decentralized decision. The win-win situation of all members of supply chain is realized. The designed revenue sharing contract is flexible, and the profit level depends on the bargaining power of supply chain members.
