Methodology for Assessing the Resilience of Networked Infrastructure

TLDR
The method includes resilience and interdependency measures, and focuses on the contribution of power delivery systems to post-event infrastructure recovery, to characterize the behavior of networked infrastructure for natural hazard events such as hurricanes and earthquakes.
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.

Review on modeling and simulation of interdependent critical infrastructure systems

TL;DR: To better understand CISs to support planning, maintenance and emergency decision making, modeling and simulation of interdependencies across CISs has recently become a key field of study and this paper reviews the studies in the field and broadly groups the existing modeling and Simulation approaches into six types.

Generic metrics and quantitative approaches for system resilience as a function of time

TL;DR: Generic metrics and formulae for quantifying system resilience are proposed that are generic enough to be implemented in a variety of applications as long as appropriate figures-of-merit and the necessary system parameters, system decomposition and component parameters are defined.

A three-stage resilience analysis framework for urban infrastructure systems

TL;DR: In this paper, a multi-stage framework is proposed to analyze infrastructure resilience and a series of resilience-based improvement strategies are highlighted and appropriate correlates of resilience identified, to then be combined for establishing an expected annual resilience metric adequate for both single hazards and concurrent multiple hazards types.

Metrics and Quantification of Operational and Infrastructure Resilience in Power Systems

TL;DR: In this article, the resilience trapezoid is defined and quantified using time-dependent resilience metrics that are specifically introduced to help capture the critical system degradation and recovery features associated to the trapezoids for different temporal phases of an event.

Fostering resilience to extreme events within infrastructure systems: Characterizing decision contexts for mitigation and adaptation

TL;DR: A conceptual framework for understanding the factors that influence the resilience of infrastructure systems in terms of robustness and rapidity is developed, and common decision contexts arise across many different infrastructure contexts when considering ways to make infrastructure systems more resilient.

Hurricane Andrew's Landfall in South Florida. Part I: Standardizing Measurements for Documentation of Surface Wind Fields

TL;DR: In this article, a set of procedures were used to represent the various types of wind measurements in a common framework for exposure, measurement height, and averaging period, and the procedures are accurate to ±10% for marine and land observing platforms, and boundary layer model adjustments of flight-level winds to the surface compare to within 20% of the nearest surface measurements.
