A Method for Assessing the Robustness of Infrastructure Networks Based on Multilayer Complex Networks

Abstract

The invention discloses a method for evaluating the robustness of an infrastructure network based on a multi-layer complex network, including: (1) constructing several different infrastructure networks into a multi-layer network according to traditional cascading dynamics; Establish a one-to-one interdependence relationship between the networks to form a multi-layer network model; (2) Simulate the process of faults in the real infrastructure network through the multi-layer network model in step (1), and calculate the multi-layer network model according to the seepage model The size of the maximum connected component when reaching the steady state; or according to the generation function and self-consistent equation theory, utilize the numerical analysis method to solve the multilayer network model in the step (1) and reach the size of the maximum connected component when the steady state; (3) according to the step The size of the largest connected component in (2) evaluates the infrastructure network robustness. This method solves the problem that the existing methods ignore the characteristics of the real network and underestimate the robustness of the network, and can evaluate the robustness of the real network more realistically.

Description

technical field [0001] The invention belongs to the field of complex network cascading dynamics, and in particular relates to a method for evaluating the robustness of an infrastructure network based on a multi-layer complex network. Background technique [0002] With the rapid development of society and the continuous advancement of technology, the internal connections between infrastructure networks in the real world have not only become intricate, but also often interdependent, interdependent, and mutually restrictive. [0003] The importance of interdependent systems for protecting the nation's critical systems was first mentioned in a 1997 report by the U.S. Commission on Critical Infrastructure Cyber ​​Protection. In reality, there are many cascading failures caused by the dependence between infrastructure networks, especially in 1998, the failure of the US Xinsi space communication satellite "Galaxy 4" communication satellite caused the continuous energy crisis in Cal...
