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.
