MCDA metrics generally try to answer the question, “what is the current state of the electric system’s resilience, and what enhances its resilience over time?” These metrics can be used to assess the system’s baseline resilience relative to other systems. They typically include categories of system properties beneficial to resilience, such as robustness, resourcefulness, adaptivity, and recoverability. The application of these metrics requires following a process to review to what degree these properties are present within the system under analysis. This usually involves collecting data through surveys, developing weighting factors, and performing calculations to obtain numerical scores. MCDA metrics are used to calculate a resilience index (RI) that accounts for about 1,200 attributes grouped in 350 categories to characterize system resilience.
