Abstract
The Model Driven Architecture (MDA) concept and key technology were discussed, including modeling technology, model transformation technology and model template. A MDA framework using UML for Platform Independent Model (PIM) and XML for Platform Specific Model (PSM) was proposed for simulation system development. The main technology of the MDA framework was introduced, which included PIM modeling guideline, PIM validity checking, PSM template, corresponding relation, symbol dictionary, CODE template and other key technologies. A MDA tool oriented simulation system was built based on the MDA framework. The tool has realized MDA process, where models in simulation system representing static and dynamic behaviors could be transformed from PIM to codes of different platforms. The MDA tool has been used in the transportation system simulation, the simulation models of different MDA periods are given, and the feasibility of applying MDA tool in the simulation system model development is verified.
