| 摘 要： | 目前,供应链系统呈现出一种复杂网状结构,可以借助复杂网络理论对其进行研究。本文探讨了供应链网络的形成过程及相应的拓扑结构,通过分析网络节点的产生、衰亡及退出状况,建立了一种择优连接模型以描述其演化过程。结果表明该模型服从指数γ=3的幂律分布,这与实证结果比较吻合。

| Abstract: | At present,the supply chain system gradually constitutes a complex network.Consequently,it can be well studied based on the complex network theory.The paper first analyzes the forming process and topology structure of the supply chain network.After that,considering the emergence,declining and withdrawal of the nodes in the real supply chain,a preferential attachment model is proposed to describe its evolutionary process.The results show that the model follows a power law degree distribution with degree expo... |
