A Novel Repair Sequence Scheduling Method for Post-Disaster Critical Infrastructure Systems

Abstract

This paper formulates the repair sequence scheduling problem for damaged component in post-disaster critical infrastructure systems (CISs) under limited repair resources in a general form and proposes a heuristic method to solve the problem. The proposed method are compared with typical existing solution methods in the literature in terms of the optimality gap and computational cost. All these methods are applied into post-earthquake damage scenarios for a real electric power system. Results show that the proposed method has better performance than existing methods and can be applied to the recovery of large-scale CISs with extensive disruptions.
