This paper considers the restoration of multiple interdependent infrastructures after a man-made or natural disaster. Modern feature complex cyclic interdependencies and require holistic process. presents first scalable approach for last-mile joint electrical power gas infrastructures. It builds on an earlier three-stage decomposition restoring network that decouples ordering routing aspects. The key contributions are (1) mixed-integer programming models finding minimal set (2) randomized adaptive to obtain high-quality solutions within required time constraints. is validated large selection benchmarks based United States state-of-the-art weather fragility simulation tools. results show significant improvements over current field practices.
