Reducing Vulnerability of Critical Infrastructures

The methodology proposed in this manual enables the study of two important types of interdependencies between essential infrastructures:
physical and geographical. It involves defining a study area and analyzing the customer-supplier relationships between critical infrastructures and the temporal and spatial consequences of the unavailability of a given resource. These consequences are presented as curves, which depict the propagation of domino effects over time in the study area. The methodology also permits
an analysis of how critical infrastructures
will fail and enables the identification
of infrastructures vulnerable to these failures. Overlaying these layers of information
allows areas that are most sensitive
to geographical interdependencies to be identified and mitigation measures to be implemented.
