The recognition that resilience is a critical aspect of infrastructure resilience has caused the national and homeland security communities to ask “How does one ensure infrastructure resilience?” Previous analysis methods have primarily focused on system recovery activities following the occurrence of a disruptive event. In this report, we expand on those methods by including pre-disruption investment options, in addition to post-event recovery activities, as means to infrastructure resilience. The report describes a stochastic optimization model for designing network infrastructure resilience to a variety of uncertain potential disruptions. The model seeks investment-recovery combinations that minimize the overall cost to a regional distribution network. A set of numerical experiments illustrates how changes to disruption scenarios probabilities affect the optimal resilient design investments.
