Infrastructure systems that exist in modern society are interdependent. In such a system, due to the interdependence, the influence of the failure that occurred in a certain system is propagated to other systems, and there is a possibility that a cascade failure occurs. Improving the robustness of the network is an important issue, however, it is difficult to completely prevent failures in the network because of its nature. Resilience is a word that has both meanings of recovery and resistance. Improving resilience means improving the ability to cope with disabilities. In this paper, we propose and verify a network restoration order determination method using the characteristics of complex networks network interdependency for the purpose of improving the resilience of network. Experimental results show that the proposed method is effective for determining the recovery order of a damaged network.
