Tiered Approach to Resilience Assessment

Marie-Valentine Renée Agnès Florin, Aleksandar Jovanovic

Regulatory agencies have long adopted a three-tier framework for risk assessment. We build on this structure to propose a tiered approach for resilience assessment that can be integrated into the existing regulatory processes. Comprehensive approaches to a ...
