公共交通网络的攻击脆弱性
Attack Vulnerability of Public Transport Networks
摘要：
复杂网络在攻击下的行为很大程度上取决于特定的攻击场景。特别令人感兴趣的是无标度网络，它通常被视为在随机故障或攻击下是健壮的，但似乎特别容易受到有针对性的攻击。在最近对世界14个主要城市的公共交通网络的研究中，我们表明这些网络可能表现出无标度行为[Physica A 380，585（2007）]。我们的进一步分析，本报告的主题，重点是失效或删除节点的公共交通网络的属性的影响。模拟不同的攻击策略，我们阐述了脆弱性标准，允许找到最小的战略，对这些系统的影响很大。
英文摘要：
The behavior of complex networks under attack depends strongly on the specific attack scenario. Of special interest are scale-free networks, which are usually seen as robust under random failure or attack but appear to be especially vulnerable to targeted attacks. In a recent study of public transport networks of 14 major cities of the world we have shown that these networks may exhibit scale-free behaviour [Physica A 380, 585 (2007)]. Our further analysis, subject of this report, focuses on the effects that defunct or removed nodes have on the properties of public transport networks. Simulating different attack strategies we elaborate vulnerability criteria that allow to find minimal strategies with high impact on these systems.
