Abstract: Restoration interdependency among infrastructures brings serious challenges to infrastructure restoration after a non-routine event. In order to restore infrastructures efficiently and orderly, it is critical making restoration decisions according to interdependency relationship. With the conditions of time and resource constraint, the paper proposes a mixed-integer programming model for infrastructure restoration design and scheduling with time-sensitive options restoration interdependency based on network flow theory. The objective of model is to maximize the cumulative performance of infrastructure restoration. Then, the applications of the model are discussed in the three typical decision-making environments containing centralized and decentralized and information-sharing decision-making environments. Finally, based on real infrastructure data set, the model is tested in the three decision-making environments, and the study finds: (1)it is feasible to apply the model to the infrastructure restoration design and scheduling after a non-routine event; (2)decision-making environments have a significantly effect on the whole cumulative performance of infrastructure restoration existing interdependency; (3)compared with decentralized decision-making environment, the whole cumulative performance of infrastructure restoration of independent decision can be improved greatly in information-sharing decision-making environment.
