Infrastructure Robustness for Multiscale Critical Missions

This paper introduces estimates of robustness across interdependent infrastructures. Robustness equates to maintaining certain functions and features of the infrastructure systems at an acceptable level during disruptions. The critical mission of a collection of components of infrastructures describes the features to be maintained. A multiscale approach provides a complete scheme to mitigate contingencies of disruptions over any collection of infrastructure components and over any geographical area. This work pertains to the challenging task of protecting our critical infrastructures and assesing resources for protecting the most valuable key assets from terrorist threats.
