摘要
首先分析了物流配送网络逐渐由简单到复杂的演变过程,然后以一类典型第三方物流企业为主体的物流配送网络为基础,以实际运营的物流配送网络为研究对象,通过大量调研记录网络中各个节点之间的关系,利用MATLAB程序实现物流配送网络节点度分布的计算,最后通过计算结果分析发现节点度分布的幂律指数符合无标度网络的特征,以物流配送网络无标度网络的特征为基础,为建立物流配送网络中的配送节点和客户节点的生成模型提供理论基础。
The paper analyzes the process of the simple-to-complex evolution of logistics distribution networks. Using a typical logistics distribution network operated by a third-party logistics company as the foundation of the study and its logistics distribution network practical operation as the study object, the paper records the node relationship through a large number of site surveys, and calculates the node degree distribution of the logistics distribution network using MATLAB Program. The result of the calculation proves thai power law index of the node degree distribution is in compliance with the characteristics of the scale-free network, which provides the theoretical basis for establishing a generative model of the distribution nodes and client nodes in the network.
