Abstract:The increased number of extreme events and the management of complex interdependent infrastructure systems produce a need for better post-disaster recovery plans. Researchers have presented important approaches in restoring components of interdependent infrastructure systems after an extreme event. These approaches include the selection of components that should be restored, the scheduling, and the assignment of these components to the restoration work crews or machines. However, the accessibility of the transportation network is ignored in previous analyses, assuming work crews can move instantaneously along the transportation network to perform restoration tasks. The availability of the transportation network is the key component that will help the restoration of other infrastructure. With this new approach, we present an interdependent network model that considers the movement of work crews based on the availability and restoration of the transportation network. We provide results from computational experiments for a set of realistic interdependent networks from Panama.
