基于中心度的中国航空客流网络抗毁性分析

摘要

以中国航空客流为样本，运用复杂网络理论，构建中国航空客流网络，并论证其系统结构特性。从点度中心度、中间中心度和接近中心度角度确定网络的关键节点，采取基于3个中心度的蓄意攻击方式，根据网络整体效能和簇系数两项指标及其下降率的变化情况，对网络的抗毁性进行了实证分析。在可视化视角下，对比分析3种蓄意攻击方式下航空客流网络结构的变化情况。研究表明：目前中国航空客流网络面对3种蓄意攻击时，网络抗毁性较弱，结构呈现出不同的变化，为此应分别从3个中心度角度出发，着重确保网络关键节点的安全，增加更多的功能不同的关键节点，优化航线网络结构。%This paper studies the air passenger flow of China ,builds the air passenger flow net‐work ,and demonstrates its system structural features by complex network theory .We determine the key nodes of the network according to Degree Centrality ,Node Betweenness Centrality ,and Closeness Centrality .Then discuss deliberate attacks based on these three centrality ,according to the variations of network overall efficiency and clustering coefficiency including their down‐trend ,we analyze the invulnerability of air passenger flow network of China .With the help of vi‐sualization technology ,we compare the structural changes of air passenger flow network of China under three different attacks .The results show that the air passenger flow network of China is weak when faced deliberate attacks . To ensure the security of key nodes in the network ,we should add more kernal hub nodes and optimize the structure of the route network .
