1. A system for simulating interdependencies between a plurality of infrastructure models of different infrastructure categories, comprising: a first infrastructure data model that models a first infrastructure, the first infrastructure being of a first infrastructure category that is selected from the group consisting of behavioral infrastructures, relational infrastructures, and physical infrastructures; a second infrastructure data model that models a second infrastructure of a second infrastructure category, the second infrastructure being of a second infrastructure category that is also selected from the group consisting of behavioral infrastructures, relational infrastructures, and physical infrastructures, wherein the second infrastructure data model is from an infrastructure category that is different from the infrastructure category of the first infrastructure data model; a simulation engine adapted to automatically produce a change in the second infrastructure data model in response to a change in the first infrastructure data model; and a user interface permitting a user to interact with the simulation engine.
