Quantitative Assessment of Economic, Social and Environmental Impacts of Critical Infrastructure Disruptions

Metrics for critical infrastructure resilience quantification and performability assessment are proposed to help in understanding the infrastructure resilience and identifying its weak spots. Analysis of critical infrastructure performance and its behavior during and after the occurrence of malfunctions and negative impacts of disruptive event of infrastructure functioning is performed through quantitative assessment. Interactions between infrastructures using indices of impact of malfunctions in them are analyzed. Proposed metrics are also concerned with demands ranging and operating and environmental conditions having influence on unrealized tasks.
