Quantification of the economic resilience from the community level to the individual business level: The bay area case study

The paper presents a methodology to evaluate economic resilience at the community level which can be applied to any type of disruptive event rather than earthquakes. The goal is to help decision makers to understand the economic resilience problem of inter-dependent networks from a community level to a business level. The case study chosen in this paper is the San Francisco Bay Area, a region which is very sensitive to natural disasters as proven by the numerous projects and institutions working on identifying performance levels to be achieved to obtain a resilient city. The two approaches - which aim to compute economic resilience and identify the effects arising from different investment allocation - are compared. Some insights on how these approaches can be implemented to evaluate the life-cycle costs of structural systems and the return of investments on preparedness measures (like building structures with higher performance with respect to the minimum required performance levels) will be investigated.
