基于MDA的仿真系统研究与实现

he MDA concept, the key technologies and development status are discussed. To develop the simulation system model better, the MDA frame is proposed that PIM is expressed by UML, and PSM is expressed by XML. The modeling principle, the translation rule, model template and other key technologies in the MDA frame are introduced. Simulation system automatic code generation flow including the dynamic model from PIM to the different languages has been initially realized by the MDA tool of facing simulation system. Take the transportation simulation system as an example, the model of MDA different periods is given, the process of applying MDA in the simulation system model development is showed. The model development and management of simulation system is improved through the application of MDA.
