Research On The Expert System Based On Fuzzy Theory For Diagnosis Of Domestic Animals Diseases

Expert system is front field of modern science and technology in the 21st century and important application of artificial intelligence in the field of production.There are following characteristics about expert system,attaching importance to knowledge (knowledge representation and knowledge application),attaching importance to reasoning(using knowledge reasoning and solving problems).Using heuristics searching algorithm and data driven model.Great benefits have been brought by its application in the fields of agriculture When an domestic animal shows disease symptoms, it is important to make an accurate diagnosis to support control strategies. Diagnosing disease in domestic animals requires considerable expertise. Only a few experts have the ability to do this, and each expert has his owm specific domain. To retain expertise and to make it more generally accessible, expert system for domestic animal disease diagnosis should be developed.In the article,firstly introduces artificial intelligence and expert system.secocdly introduces theory and applications of fuzzy mathematics.then the architecture and function of the platform for agriculture development are described. It supports network and component development Key techniques, running environment, interface standard, extension and application are expatiated. We have analyzed the system structure of computer network and the character of required services provided by AIIT, constructed internet-based computer agriculture information network and devised expert system matching it. An open and flexible architecture for general component expert system development platform based on author's former expert system development works is proposed. This architecture supports customized, composed and cooperated developing for detail expert system designer. The expert system constructing problem is divided into three levels, they are constructing function component, composing single expert system and assembling distributed agent system. According with the analysis of the architecture of expert system platform, three software models to compose different layers of the expert system are built up.Finally, this article gave the implementation of the expert system. The software structure referenced the Browser/Server model in popular network techniques. The browser software was a Web browser, e.g. Microsoft Internet Explorer (IE) ,Netscape Communicator,Express and so on. The server software was Microsoft Internet...
