通过改变边连接来提高互依网络鲁棒性的方法有两种。一个是改变连接链路,另一个是改变互连链路。在本文中,我们专注于影响连锁故障传播的因素。并在研究故障传播过程的基础上,找出影响连锁故障传播的两个因素。最后,提出了一种局部优化NPC(Neighbor node priority connection)耦合策略。通过将该策略应用于ER-ER和SF-SF两类相互依赖网络,我们发现NPC耦合的相互依赖网络的鲁棒性优于三种经典策略。
There are two kinds of methods to improve the robustness of interdependent networks by changing the edge connection. One is to change the connectivity link, and the other is to change the inter-links. In this paper, we focus on the factors that affect the propagation of cascading failures. And based on the study of the propagation process of failures, the two factors affecting the propagation of cascading failures are found. Finally, a coupling strategy of local optimization NPC (Neighbor node priority connection) is proposed. By applying this strategy to two kinds of interdependent networks ER-ER and SF-SF, we find that the robustness of the interdependent networks coupled by NPC is better than that of the three classical strategies.
