After extreme events, a community's socio-economic recovery depends on the recovery of its infrastructure systems, such as power and water distribution systems, transportation networks, communications systems, and critical buildings. We need to build resilient infrastructure systems to support the national economy and wellbeing of citizens, resist extreme events, and ensure their capacity to rapidly recover to full service afterwards. The PRAISys (Probabilistic Resilience Assessment of Interdependent Systems) platform will perform post-event resilience analysis of communities by addressing stochastic interdependencies among infrastructure systems in a probabilistic way.
