Abstract:

To solve the problems that the directed dependency edge is not considered in the study of cascading failure of interdependent networks, the cascading failure analysis of interdependent networks based on asymmetric dependency is carried out. A cascading failure model based on load-capacity is constructed. A robustness measurement method for interdependent networks based on connected components is proposed. The research on network robustness of different network combinations, coupling methods, tolerance coefficients and removal ratios under different attack modes is carried out. The results show that the robustness of asymmetric interdependent networks in random attack mode is similar to previous research conclusions. The robustness of asymmetric interdependent networks in intentional attack mode depends on the size of the attack range and tolerance coefficient. The analysis of an air combat system network example illustrates the practical application value of the research, and it has certain reference signification for perfect the theoretical research of interdependent networks.
