Continuous and multidimensional assessment of resilience based on functionality analysis for interconnected systems

International audienceThe increasing number of disruptions, from natural disasters to terrorist attacks, is today a major concern of our modern society. As a result, to the interdependent nature of infrastructures, disruptions cause domino and cascade effects. For instance, a disruption in an energy infrastructure affects a rail-transportation infrastructure that further affects other infrastructures. Mitigating the negative effects means that the infrastructures must recover in minimum time, with minimum costs their initial functioning capacity, i.e., they must be resilient. So, stakeholders must analyse the resilience of infrastructures before any disruption to anticipate the right decisions. This article studies the concepts of resilience and resilience assessment to bridges the gap between rough stakeholders’ data and resilience evaluation for interdependent systems. The result is an original toolequipped approach that combines continuous with multidimensional resilience evaluation and assessment. The approach is based on simple and generic criteria that can be extended and adapted depending on the context and needs
