随机故障和定向攻击下的公交网络

Public Transport Networks under Random Failure and Directed Attack

Bertrand Berche, Christian von Ferber, Taras Holovatch, Yurij Holovatch

摘要:

复杂网络在故障或攻击下的行为很大程度上取决于特定的场景。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,我们已经表明,这些系统在用适当的图表示时可能会表现出无标度行为。在本文中,我们简要地回顾了一些最近的结果,失效或删除节点的公共交通网络的性能的影响。模拟不同的定向攻击策略,我们得出的脆弱性标准,导致最小的战略,对这些系统的影响很大。

英文摘要:

The behaviour of complex networks under failure or attack depends strongly on the specific scenario. Of special interest are scale-free networks, which are usually seen as robust under random failure 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 systems when represented by appropriate graphs may exhibit scale-free behaviour. In this paper we briefly review some of the recent results about the effects that defunct or removed nodes have on the properties of public transport networks. Simulating different directed attack strategies, we derive vulnerability criteria that result in minimal strategies with high impact on these systems.
