摘要
为了更精准的预测复杂网络中的薄弱环节并针对其采取预防措施,结合节点度数和节点介数的分析方法设计一种基于节点重要度的复杂网络脆弱性分析方法,将网络效率作为衡量网络性能的指标,并以某地区城区铁路网络为案例进行单节点攻击和多节点攻击仿真实验来验证所提方法的性能。仿真实验表明,所提方法所得的结果比高度数节点法和高介数方法所得预测结果更好,可以更加准确的预测网络中的薄弱环节。
In order to predict the weak links in complex networks accurately and take preventive measures against them,this paper designs a vulnerability analysis method of complex networks based on node importance combining with node degree and node betweenness analysis method.The network efficiency is taken as an index to measure the network performance,and the simulation of single-node and multi-node attacks is carried out with a case of railway network in urban area.Experiments are carried out to verify the performance of the proposed method.The simulation results show that the results obtained by the proposed method are better than those obtained by the high-degree node method and the high-betweenness method,and the weak links in the network can be predicted more accurately.
