Building resilience into today's complex infrastructures is critical to the daily functioning of society and its ability to withstand and recover from natural disasters, epidemics, and cyber-threats. This study proposes quantitative measures that capture and implement the definition of engineering resilience advanced by the National Academy of Sciences. The approach is applicable across physical, information, and social domains. It evaluates the critical functionality, defined as a performance function of time set by the stakeholders. Critical functionality is a source of valuable information, such as the integrated system resilience over a time interval, and its robustness. The paper demonstrates the formulation on two classes of models: 1) multi-level directed acyclic graphs, and 2) interdependent coupled networks. For both models synthetic case studies are used to explore trends. For the first class, the approach is also applied to the Linux operating system. Results indicate that desired resilience and robustness levels are achievable by trading off different design parameters, such as redundancy, node recovery time, and backup supply available. The nonlinear relationship between network parameters and resilience levels confirms the utility of the proposed approach, which is of benefit to analysts and designers of complex systems and networks.read more

Resilience and efficiency in transportation networks

TL;DR: It is demonstrated that many urban road systems that operate inefficiently under normal conditions are nevertheless resilient to disruption, whereas some more efficient cities are more fragile, and resilience, not just efficiency, should be considered explicitly in roadway project selection and justify investment opportunities related to disaster and other disruptions.

Validating resilience and vulnerability indices in the context of natural disasters
TL;DR: It is found that disaster indices, though thoughtfully substantiated by literature and theoretically persuasive, are not all created equal and policymakers should use index results carefully when developing regional policy or investing in resilience and vulnerability improvement projects.

Resilience Analysis of Critical Infrastructures: A Cognitive Approach Based on Granular Computing
TL;DR: This paper is argued to be the first work that combines GrC and resilience analysis of CIs, and an illustrative example that shows how to apply the results, and a discussion on the necessary contextualizations and extensions of the GrC results to be better adapted for CIs resilience.

Bouncing forward: a resilience approach to dealing with COVID-19 and future systemic shocks.
TL;DR: This paper reviews the impact of COVID-19 on socioeconomic systems, discusses the notion of resilience, and provides specific recommendations on both integrating resilience analytics for recovery from the current crisis as well as on building resilient infrastructure to address future systemic challenges.

The Resilience to Emergencies and Disasters Index: Applying big data to benchmark and validate neighborhood resilience capacity
TL;DR: Hurricane Sandy had a significant and immediate impact on neighborhoods classified as least resilient based on the calculated REDI scores, while the most resilient neighborhoods were shown to better withstand disruption to normal activity patterns and more quickly recover to pre-event functional capacity.

Resilience and Stability of Ecological Systems
TL;DR: The traditional view of natural systems, therefore, might well be less a meaningful reality than a perceptual convenience.

Catastrophic cascade of failures in interdependent networks

TL;DR: In this paper, the authors develop a framework for understanding the robustness of interacting networks subject to cascading failures and present exact analytical solutions for the critical fraction of nodes that, on removal, will lead to a failure cascade and to a complete fragmentation of two interdependent networks.

TL;DR: This work offers a comprehensive review on both structural and dynamical organization of graphs made of diverse relationships (layers) between its constituents, and cover several relevant issues, from a full redefinition of the basic structural measures, to understanding how the multilayer nature of the network affects processes and dynamics.
