Modelling and Simulation of Interdependent Critical Infrastructure: The Road Ahead

Developed societies base their existence on services and resources provided by an increasingly complex network of interdependent critical infrastructures, from power distribution and communication networks, to logistics and healthcare systems, to the Internet. Understanding the behaviour of this system of systems under normal and exceptional circumstances is a mandatory step in order to reduce our dependence and design strategies to increase its dependability. Unfortunately, its complexity overcomes the capability of available methods. In the chapter, we provide an overview of the emerging methodologies and tools, discussing relative potentials and limits.
