连锁故障的非局部效应及对策
Nonlocal effects and counter measures in cascading failures
摘要：
我们研究了复杂供应网络中连锁故障的传播，重点是远离初始故障发生的非局部效应。它示出了一个高的聚类和一个小的平均路径长度的网络一般抑制非局部过载。这些属性对于许多现实世界的网络（通常称为小世界网络）来说是典型的，因此级联在这些网络中主要是局部传播的。此外，我们分析了空间方面的对策的基础上有意去除额外的边缘。在冗余度低的网络中，通常需要非局部动作，因此特别容易受到级联的影响。
英文摘要：
We study the propagation of cascading failures in complex supply networks with a focus on nonlocal effects occurring far away from the initial failure. It is shown that a high clustering and a small average path length of a network generally suppress nonlocal overloads. These properties are typical for many real-world networks, often called small-world networks, such that cascades propagate mostly locally in these networks. Furthermore, we analyze the spatial aspects of countermeasures based on the intentional removal of additional edges. Nonlocal actions are generally required in networks which have a low redundancy and are thus especially vulnerable to cascades.
