In this paper, the characteristics of the object oriented modeling method are discussed firstly, then the parametric object expression, object construction and assembly, and the mechanism of establishing and managing the parametric object model are described.

The progress of object-oriented modeling on aerial armament test system software has been introduced in details.

In this paper, the object-oriented modeling technology is used to design the air conditioner simulation system, and the structure, function and components of the system are designed and described in detail by using Unified Modeling Language (UML) to design the Use Case Diagram, the Class Diagram and the Sequence Diagram.

The root basis of the model was extended object model,which was constructed by augmenting the conventional object model in object-oriented modeling methodology with relationship object set R and constraint object set C.

For realizing the self-adaptive simulation of the whole transient process,this paper proposes the theory of Object-Oriented Modeling(OOM) by analyzing the class structure of power system elements.

The object oriented technique (OOT) and Object oriented modeling (OOM) are mainstream methods of developing software nowadays, as they provide the approaches of analysis and modeling to sole software crisis with the traditional structured developed mode, which limits the geophysical software developing at some degree in China.
