Enabling System of Systems Analysis of Critical Infrastructure Behaviors

Critical infrastructures are highly complex collections of people, processes, technologies, and information; they are also highly interdependent where disruptions to one infrastructure commonly cascade in scope and escalate in impact across other infrastructures. While it is unlikely that disruptions can be prevented with certainty, an effective practice of critical infrastructure analysis can reduce their frequency and/or lessen their impact. We contend that proper critical infrastructure analysis necessitates a system of systems approach. In this paper, we identify requirements for integrated modeling and simulation of critical infrastructures. We also present our integrated modeling and simulation framework based on a serviceoriented architecture that enables system of systems analysis of such infrastructures.
