Resilience of Interdependent Critical Infrastructures: A Case Study in Quebec (Canada)

Managing interdependencies among critical infrastructures (CIs) represents a constant challenge for local authorities. When assessing a community's resilience, this challenge takes on all its importance. Civil security authorities are responsible for taking on this challenge and ensuring continuity in the assessment of resilience. The work of the Centre risque & performance (CRP) in Montréal has identified the core element to support the authorities. The space of resilience that authorities need to create to better manage interdependencies among CIs allows them to directly analyze the resilience of CIs in their territory. The DOMINO tool developed by the CRP supports the authorities in portraying CIs and their dependence, analyze resilience as a temporal and geographical simulation of failure and, ultimately, maintain the space of resilience that ensures collaboration sustainability and integrate them into high-performance system.
