A two-stage approach to simulate interdependent critical infrastructures

Nowadays the simulation of scenarios composed by interdependent critical infrastructures is a challenge. One of the main challenge is how to manage into a single framework heterogeneous and interdependent infrastructures characterized by very different time scales, modeling paradigms and functional behavior. In this paper we propose a two-stage approach, where several sector specific simulators are integrated within a common framework by means of multi-domain simulation platforms. We describe the rational behind our approach and its advantages with reference to two complementary implementations: CISIA and Federated ABMS.
