Creating a simulation environment for critical infrastructure interdependencies study

The critical infrastructures (CIs) on which our daily life depends are mutually interdependent. What happens to one infrastructure can directly or indirectly affect another infrastructure or maybe even more. The development of advanced techniques of modeling and simulation is significant for the interdependencies study between CIs. In this paper, an approach to model critical infrastructures as well as adopting HLA (High Level Architecture) to simulate the interoperations between individual models under system-of-systems design architecture is proposed. Two examples of interdependent systems (CIs), which are studied in this approach, are : Electric Power Supply (EPS) System and Supervisory Control and Data Acquisition (SCADA) System.
