基于复杂加权网络理论的中心可靠性分析

Center Reliability Analysis Based on Complex Weighted Network Theory

轨道交通作为城市客运体系中的重要支柱,站点瘫痪会影响网络的连通性和运营效率。文章采用Space L法构建拓扑模型,建立定量化评价站点可靠性的指标,并以某市地铁线网为例,利用Matlab软件分析节点度和度分布、平均路径长度、聚类系数和介数等特征指标的分布规律,量化分析各站点在遭受随机性攻击和选择性静态与动态中心节点攻击条件下的可靠性变化,确定出网络的结构类型及中心站点,为日常的运营优化和规划建设提供科学依据。

Rail traffic is an important pillar in urban passenger transport system, the station failure will affect the network connectivity and operation efficiency.This article established the topology model through space L method, determined the quantitative evaluation index for station reliability, then, with the subway network in a city as the example, it analyzed the distribution rules of characteristic indexes such as node degree, degree distribution, average path length, clustering coefficient and number by Matlab software, quantitatively analyzed the reliability changes of various stations under the conditions of random attack and selective static and dynamic center node attack,determined the network structura type and the central station ,thereby providing the scientific basis for the daily operation optimization and planning construction.
