The region analyzed in the case study includes New York City and some New Jersey counties. The highly concentrated critical infrastructures of this area are vulnerable to the direct impact of catastrophic events, such as hurricanes, as well as to the disruptive cascading effects that are spread through the existing interdependencies. The Inoperability Input-Output model, developed by Haimes and Jiang, is selected to numerically define the degree of interconnection among these systems and quantify the effect of an external perturbation on the network's functionality. Based on the model's results, a new indicator, named the "inoperability ratio," is introduced to select and rank the priority actions that policymakers should implement during the restoration process. These initiatives reduce the inoperability ratio to prevent cascading effects and to improve the overall resilience in the region. Thus, these ratios also allow for primary and secondary initiatives to be distinguished.
