Abstract
Recent extreme events have shown that total protection can not be accomplished. Therefore, Critical Infrastructure Protection (CIP) strategies should focus not only on the prevention of these events but also on the response and recovery following them. This shift in CIP strategies has put more interest on the concept of infrastructure resilience. In this paper, we address the problem of assessing critical infrastructure resilience. We first define the infrastructure attributes that make it resilient. Then, we propose a modeling framework to capture these attributes. After that, a resilience index is introduced to quantify the resilience of infrastructure systems. Finally, the usefulness of the proposed framework is demonstrated through an illustrative example.
