Critical infrastructures are those upon which a country’s health, economy, and security collectively depend. Understanding interdependencies and dynamics between critical infrastructures will enhance communication and coordination between emergency management and homeland security as well as many other authorities. This project addresses the need for assessing the supply chains of petrochemical products within a petrochemical complex. A geometric network was used to model connectivity between different supply chain networks in the petrochemical complex. ArcGIS Utility Network was used to create failure events on the failed facilities and select the impacted facilities. Then the Failure Consequences Model was used to provide graphical and statistical figures on the cascaded failure impact.
