中文摘要：
针对复杂网络遭遇蓄意攻击引发的相继故障问题,采用Physical ReviewE77,026101（2008）所提出的相继故障模型,对比了BA无标度网络和WS小世界网络上遭遇两种边袭击策略导致的全局相继故障现象,并探讨了网络拓扑结构对边袭击策略的影响.理论解析和数值模拟均表明了在模型中可调参数的一定取值内,袭击网络中负荷最小的边比袭击网络中负荷最大的边更易于导致相继故障现象,而且,网络拓扑结构的不同对袭击策略也有着非常重要的影响.
英文摘要：
In order to discuss cascading failures on complex networks subject to attacks,this paper adopts a cascading failure model presented in Physical Review E 77,026101（2008）,compares the universal cascading failure phenomena on BA scale-free and WS small-world networks subject to two different attacks on edges, and explores the effects of network structures on edge attack strategies.Both theoretical analysis and numerical simulations indicate that the attack on the edges with the lowest loads is more prone to trigger cascading failures than the attack on the ones with the highest loads in the certain range of the tunable parameter,and the difference network structures have much important effects on attack strategies.
