【摘要】：供应链是一种动态的、自适应性、自组织的复杂网络系统,具有典型的复杂网络特征。考虑了供应链网络的整体宏观行为,通过分析企业节点的产生、衰亡及退出等生长演化规律,以节点多属性参数组合作为优先连接的依据,建立了一个分层加权供应链网络模型。实验结果显示,该模型具有无标度特性,其幂律分布的指数落在(2,3)范围内,而且具有较大的集聚系数及较小的平均路径长度,表明了其具有小世界效应。
[Abstract]:Supply chain is a dynamic, adaptive, self-organized complex network system with typical complex network characteristics. Considering the overall macroscopic behavior of the supply chain network, by analyzing the rules of growth and evolution of the enterprise nodes, such as the generation, decline and exit of the enterprise nodes, the paper takes the combination of the multi-attribute parameters of the nodes as the basis of priority connection. A hierarchical weighted supply chain network model is established. The experimental results show that the model has scale-free property, the exponent of the power law distribution falls within the range of (2 ~ 3), and it has a large agglomeration coefficient and a smaller average path length, which indicates that the model has a small world effect.
