Application: Resilience Investment and Design for Infrastructure Distribution Networks


Graph of probability distribution of Total Impact across ScenariosPrevious network resilience analysis methods have generally focused on either pre-disruption prevention investments or post-disruption recovery strategies. The ability to identify combinations of pre- and post-disruption activities that enhance resilience could provide a more comprehensive approach for designing infrastructure resilience. This application introduces a mathematical model that seeks investment-recovery combinations that minimize the overall cost to a distribution network across a set of disruption scenarios. A set of numerical experiments illustrates how changes to disruption scenarios probabilities affect the optimal resilient design investments.
