Interdependent critical infrastructures resilience: methodology and case study

Abstract

Purpose – The purpose of this paper is to present a coherence analysis to evaluate the resilience for a critical infrastructure (CI). This is the new way to evaluate the CI and demonstrate that the authors need to pass from the protection towards resilience. Design/methodology/approach – The authors use two approaches for this research. First is a consequence-based approach to evaluate the resilience. This approach has been used many times for evaluating the interdependencies between CIs. The second is a systemic approach to characterize the system and doing the coherence analysis. Findings – This paper presents a methodology to evaluate the coherence in a context of CIs protection. The coherence analysis in resilience is a new concept and the first result to the application seems very good for the user of the research. Originality/value – The originality of this paper is the coherence analysis applied to a resilience evaluation. The criteria for coherence analysis is innovative and it is a new way to consider the resilience and the relation between an organization and it is partners. Another value is the need for a wider scope in the analysis of hazards and how to address them that includes the infrastructure system itself, but also other related organizations and infrastructure systems.

Systematic review of critical infrastructure resilience indicators

“…Understanding the loss of performance associated with a disruptive event and the recovery time is essential to enhance the resilience of CIs. The loss of performance in CIs is directly linked to the type of crisis faced on a specific occasion, and the lack of communication among different organisations (Petersen et al , 2020; Robert et al , 2015). Evaluating the actual physical losses (extension of the infrastructure damage) and focusing on the potential for resilient behaviour (community’s static capacity for resilience) are two approaches suggested to measure a community’s resilience.…”
