Research on Virtual Range Multi-domain Modeling Methodology Based on Metamodel

摘要

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 multidomain 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.
