基于节点状态的中南地区民航网络级联失效

随着中国各类突发事件的频繁发生,为保障民航交通网络的安全运营,使民航网络在不断动态演化过程中保持较强的网络抗毁能力,通过复杂网络理论构建民航网络级联失效模型,该模型根据级联失效现象下民航网络节点的变化情况,构建了一种基于节点状态的民航网络容量-负载级联失效模型,模型中的网络节点包含"正常-失效-暂停"三种状态.以中南地...

Analysis on the robustness of civil aviation network cascade failure in central and south China based on node state

With the frequent occurrence of various emergencies in China, in order to ensure the safe operation of civil aviation traffic network and maintain the strong network anti damage ability in the process of continuous dynamic evolution, In this paper, the cascaded failure model of civil aviation network is constructed by the theory of complex network. According to the change of nodes in civil aviation network under cascading failure, a cascading failure model of capacity load in civil aviation network based on node state is constructed. The nodes in the model include three states of "normal-failure-pause". A case study of civil aviation network in Central South China. The results show that the improved cascading failure model of civil aviation network can simulate the cascading failure process more accurately, and the robustness of the network under selective attack is poor. According to the analysis of simulation results, when optimizing the civil aviation network, we should pay attention to improving the robustness of key nodes of the network, which can effectively improve the safe operation of the network.
