MODELING COMPLEX HIEARCHICAL SYSTEMS ACROSS SPACE AND TIME

A system model of a real-world system includes a multi-level hierarchy of Capabilities, where each Capability includes a Verb specifying an action and an Object acted on by the Verb. The system model also contains one or more multi-level Performer hierarchies, where each Performer hierarchy includes a plurality of Performers each having an associated lifecycle and at least one associated Capability provided or required by the Performer. In addition, a multi-level Location hierarchy associates one of a plurality of Locations with each Performer. A plurality of Capability Instances define requirement and provision of Capabilities by Performers in the one or more multi-level Performer hierarchies. In response to a query specifying a Location and a time, a view of the system model for the specified Location and time is output.
