“…However, the most common resilience analyses deal with descriptive and qualitative analysis. It is then still challenging to define consensual metrics for quantitative resilience analysis (Hollnagel et al 2008;Johnston et al 2008;Hollnagel et al 2011;Stewart & Yuen 2011;Barker et al 2012;Dinh et al 2012;Miller-Hooks et al 2012;Shirali et al 2012;Francis & Bekera 2014;Manyena 2014;Matthews et al 2014;Pant et al 2014;Roege et al 2014;Shafieezadeh & Burden 2014;Aldunce et al 2015;Angeon & Bates 2015;Bond et al 2015;Cardoso et al 2015;Chopra & Khanna 2015;Dijkstra & Viebahn 2015;Kelman et al 2015;Khalili et al 2015;Labaka et al 2015;Lindbom et al 2015;Lundberg & Johansson 2015;Mugume et al 2015;Oken et (Mebarki et al 2014a(Mebarki et al , 2014bMebarki and Barroca 2015).

The paper presents an integrated framework which deals with natural hazards (tsunamis), physical vulnerability modelling, risk of failure for industrial structures (metal structures) and structural resilience provided by plastic adaptation. Simplified models are proposed to describe the runup and wave height attenuation in case of tsunamis. The results are calibrated in the case of important tsunamis having taken place in Asian region. The mechanical vulnerability of cylindrical metal tanks erected near the shoreline is also investigated. The fragility curves are then developed in order to describe the multimodal failure: overturning, rupture of anchorages and sliding, buoyancy, excessive bending effects or buckling. Corresponding fragility curves are developed under various conditions: height of tsunami waves, filling ratios and service conditions of the tanks, friction tank/ground as well as dimensions effects. Probabilistic description of the natural hazard and the fragility curves are presented. Sensitivity analysis is also performed in order to investigate the effect of various governing parameters. Furthermore, resilience concepts and metrics are proposed. Theoretical description of the damages and postdisaster recovery functions are discussed: plastic adaptation as well as elastic and plastic attractors.

“…Since it is extremely difficult to predict the direct and indirect consequences of a disruption on a complex, large-scale system, quantifying resilience in terms of the recovery time required for a system to return to its equilibrium state is even more difficult. The definition of resilience used in this study is a reworking of ecological resilience for industrial and infrastructure systems [41,42]. Henceforth, resilience in this paper refers to the ability of a system to maintain its structure and function in the face of disruptions.…”

Modern society is increasingly dependent on the stability of a complex system of interdependent infrastructure sectors. It is imperative to build resilience of large-scale infrastructures like metro systems for addressing the threat of natural disasters and man-made attacks in urban areas. Analysis is needed to ensure that these systems are capable of withstanding and containing unexpected perturbations, and develop heuristic strategies for guiding the design of more resilient networks in the future. We present a comprehensive, multi-pronged framework that analyses information on network topology, spatial organization and passenger flow to understand the resilience of the London metro system. Topology of the London metro system is not fault tolerant in terms of maintaining connectivity at the periphery of the network since it does not exhibit small-world properties. The passenger strength distribution follows a power law, suggesting that while the London metro system is robust to random failures, it is vulnerable to disruptions on a few critical stations. The analysis further identifies particular sources of structural and functional vulnerabilities that need to be mitigated for improving the resilience of the London metro network. The insights from our framework provide useful strategies to build resilience for both existing and upcoming metro systems.

“…Cascading effects of some real‐world hazards such as earthquakes, terrorist attacks like economic effects of the 9/11 attack (for example, the considerable disorder in international trade as the result of making international movements harder under more restrictive security concerns), power outages like the 2003 Italy blackout, and so on motivated researchers to study and evaluate the effects of cascading failures in interdependent networked systems . The studies showed that small‐ or large‐scale failures in some critical infrastructure sectors (CISs), including cyberspace, potentially cascade and make catastrophic events . It is evident that the stability of the security and economy of nations are tightly influenced by threats to the cyberspace from different sources.…”

Security of the systems is normally interdependent in such a way that security risks of one part affect other parts and threats spread through the vulnerable links in the network. So, the risks of the systems can be mitigated through investments in the security of interconnecting links. This article takes an innovative look at the problem of security investment of nodes on their vulnerable links in a given contagious network as a game-theoretic model that can be applied to a variety of applications including information systems. In the proposed game model, each node computes its corresponding risk based on the value of its assets, vulnerabilities, and threats to determine the optimum level of security investments on its external links respecting its limited budget. Furthermore, direct and indirect nonlinear influences of a node's security investment on the risks of other nodes are considered. The existence and uniqueness of the game's Nash equilibrium in the proposed game are also proved. Further analysis of the model in a practical case revealed that taking advantage of the investment effects of other players, perfectly rational players (i.e., those who use the utility function of the proposed game model) make more cost-effective decisions than selfish nonrational or semirational players.
