Methodology for Assessing the Resilience of Networked Infrastructure

TLDR

The model is an important component of a scheme to develop design strategies for increased resilience of urban infrastructure for extreme natural hazard scenarios. The paper outlines a method to characterize the behavior of networked infrastructure during natural hazards, focusing on how power delivery systems influence post‑event recovery. The method incorporates resilience and interdependency measures to assess networked infrastructure behavior, using power delivery and telecommunications data. An example calculation using post‑landfall power delivery and telecommunications data from Hurricane Katrina demonstrates the approach.

Abstract

In this paper, we outline a method to characterize the behavior of networked infrastructure for natural hazard events such as hurricanes and earthquakes. Our method includes resilience and interdependency measures. Because most urban infrastructure systems rely on electric power to function properly, we focus on the contribution of power delivery systems to post-event infrastructure recovery. We provide a brief example of our calculations using power delivery and telecommunications data collected post-landfall for Hurricane Katrina. The model is an important component of a scheme to develop design strategies for increased resilience of urban infrastructure for extreme natural hazard scenarios.
