Abstract: A system for simulating interdependencies between a plurality of infrastructure models includes a first infrastructure data model that models a first infrastructure, a second infrastructure data model that models a second infrastructure, a simulation engine including a society of software agents and adapted to automatically produce, in response to a first change in the infrastructure data model, a second change in the infrastructure data model, and a user interface permitting a user to interact with the simulation engine. The system is adapted to simulate interdependencies between different critical infrastructure models as well as interdependencies between an infrastructure of one infrastructure category and an infrastructure of a different infrastructure category. Infrastructure categories include behavioral infrastructures, relational infrastructures, and physical infrastructures.
