Deliverable D 2.2.2 - Tools and techniques for interdependency analysis

Interdependencies between infrastructures imply that an impact on one infrastructure is also an impact on one or more other infrastructures. In literature, different types of interdependencies have been identified and their classification has been attempted. Particularly, infrastructures can have input, mutual, co-located, shared, exclusive interdependencies and/or also can interact at different levels: physical, cyber, geographic and logical. There are different approaches for model based vulnerability analysis of interdependent infrastructures. Two leading approaches are represented by agent-based simulation and inputoutput analysis; a third one approach is represented by network models, coming from reliability analysis and complexity science. The deliverable focuses on the investigation of methods and tools for interdependency analysis throughout their possible usage inside a preliminary modelling process, in which the different types of models are built, with reference to an actual scenario. A preliminary demonstration of methods and models for vulnerability assessment of interdependent infrastructures and, as a consequence, a demonstration of the related tools and techniques is also given.
