Research on Methodology of Object-Oriented Modeling in Concurrent Design

On the basis of events and the object oriented thought, this paper analyzes the functions of a system as a whole, puts forward Object Operation Diagram and Object Function Matrix, and discusses their functions and properties, then expounds the method and process of object oriented modeling in concurrent design with the two tools. Compared with the existing object oriented methods, the modeling method in this paper makes the classes and objects obtained in analysis and design to be complete, consistent and objective, and the modeling process to be more effective.
