Visual Rice Growth Models system represented an effort to design crop modeling software with object-oriented paradigm and to organize classes in system with model-document-view architecture. Firstly, the crop-environment system was abstracted as many subsystems and physiological processes with object-oriented paradigm while many classes were established to simulate the behaviors of these subsystems and physiological processes. In VRGM, the document-view architecture in Visual C++ was extended as model-document-view architecture for agricultural integrated system. In the model-document-view architecture, document gets the final simulation results by manipulating the models classes and acts as a communicating intermediacy between model and view. Views display the simulation results and translate users' operation and data entering to document. The architecture separates the domain models, data management and user interface.

To avoid the collision accidents of ships at sea, with the universalizing and application of computer, and the development and maturity of the technology of Expert System and Artificial Intelligent, this paper developed an intelligent collision avoidance expert system for navigation. The main research work centers on several aspects, which will be represented as below:By the navigation rules" understanding and analyzing, and by the navigation experience and navigation samples" collecting and trimming, we put forth and build a multi-unit and layering KB systematic structure, and implement the KBM. According to features of different knowledge, we adopt multifarious KR, such as: frame KR, production rule KR, procedure KR. We also build a multi-inference system, which based on analog inference, forward illation inference, conversion inference and meta-rule inference. At the same time, we develop each reasoning algorithm. For some problems in collision avoidance region during the building of the expert system, we put forth and build a set of models to solve them using neural network technology.
