摘要
选取公路交叉口作为网络拓扑节点,以节点间的连通关系作为网络拓扑边,基于对偶法,利用MATLAB构造出了抽象的宁夏公路网拓扑图,并计算出节点度、网络聚集系数和平均最短路径长度等路网复杂特征指标,通过对需求网、拓扑图和特征指标的定量和定性分析,结合宁夏冷链物流企业间的企业网络定性分析,总结出了宁夏冷链物流网络的现状,并由此发现了其发展过程中的问题,并提出了相关的对策建议。
This paper selects the highway intersections as nodes of the network topology and selects the relation between the nodes as edge of the network topology. The Ningxia highway network topology graph is constructed by MATLAB based on the dual method. At the same time, this paper calculates some network complexity characteristic indexes such as the node degree, clustering coefficient and average shortest path length. Based on the quantitative and qualitative analysis of the demand network, the topology graph, the characteristic index and the enterprise network of Ningxia cold chain logistics enterprises, this paper sums up the status of Ningxia cold chain logistics network, found the problems in the development process, and thus puts forward relevant countermeasures and suggestions.
