The identification and mitigation of interdependencies among critical infrastructure elements such as telecommunications, energy and transportation are important steps in any protection strategy and are applicable in preventive and operative settings. This paper presents a graph-theoretical model and framework for analyzing dependencies based on a multigraph approach and discusses algorithms for automatically identifying critical dependencies. These algorithms are applied to dependency structures that simulate the scale-free structures found in many infrastructure networks as well as to networks augmented by random graphs.

Keywords: Infrastructure interdependencies, multigraph models, simulation
