摘　　要：在一般局域世界演化模型基础上,建立了供应链复杂网络的局域演化生长模型。应用节点间相关度的概念来确定每一新加入节点的局域世界,并定义局域世界的规模是动态增加的。通过解析的方法,导出这一模型的度分布、聚类系数和平均路径长度,发现其具备复杂网络的无标度、小世界等特性,并通过数值仿真进行了验证。Based on the simple local-world evolving network model, we propose a local-world evolving growth model of the complex supply chain network. Using the concept of correlation degree between nodes we build a local world of each node in the network, and the size of the local-world increases with time. Using analytical computing, we get the expression of degree distribution, cluster coefficient and average path length, and find this network model possessing complex networks＇ characteristics like scale-free and small-world. Finally, numerical simulations are given to validate the results.
