不同攻击模式下中国航路网络抗毁性研究

Research on the Invulnerability of China's Air Route Network under Different Attack Strategies

运用复杂网络理论,分别对随机攻击模式和蓄意攻击模式下中国航路网络的抗毁性进行分析.分析两种攻击模式下最大连通子图的大小、聚集系数、平均度以及最大度的变化.结果表明:在随机攻击模式下,最大连通子图的大小更适合用来衡量一个网络的抗毁性;而当采用蓄意攻击时,度值攻击可以有效反映网络的抗毁性;中国航路网络具有随机攻击下抗毁性较强,而面对蓄意攻击抗毁性偏弱的特性.

The theory of complex network is used to study the invulnerability of China’s air route network under random attack strategy and intentional attack strategy. Under these two different attack strategies, this paper analyzes the changes in the size of the maximum sub-graph, cluster coefficient, mean degree and maximum degree, respectively. The results are as follows： the size of the maximum sub-graph is more suitable to describe the invulnerability of a network under random attacks, while the degree attack can be used to characterize the invulnerability when intentional attacks are applied. Besides, China’s air route network shows a strong invulnerability to random attacks, but a weak invulnerability to intentional attacks.
