Research on Virtual Range multi-domain modeling methodology based on Meta-model

To achieve the integration and interoperability of the Virtual-Range multi-domain models, the meta-model theory and the meta-modeling method are introduced. Following the Meta Object Facility specification, a multi-domain meta-model hierarchical structure of Virtual-Range is proposed to facilitate the meta-model development. Based on that, a general meta-modeling method for integrating the Virtual-Range multi-domain models is presented. A Virtual-Range system is decomposed into multiple single domain subsystems by the method first, and the meta-model components of each subsystem are built up by concept abstraction. The Backus-Naur Form is adopted to formalize the established meta-models, providing a uniform semantics for model integration and reuse. An available Virtual-Range simulation system was designed with the proposed meta-model modeling method, and the multi-domain models can be integrated in a higher level with the new system architecture.
