Research And Application Of Testing And Training Expert System Based On Web

With the rapid development of the Internet,web-based expert systems have been researched and applied because of the limitation of the traditional expert systems.It is the inevitable development direction to the expert system.However now the web-based expert systems are facing the problem of lacking suitable developing tools.In order to improve the efficiency of the expert system design and development and shorten the development cycle of an expert system,take the crane knowledge as the demand,the thesis study the designing and the realization about the testing and training expert system based on web.By introducing the concepts and structures of web-based expert systems,the thesis points out the existing system imperfections in the development technology through the researches and analyses of the current test experts.The thesis introduces the advanced "browsers/web server/database system ",three-tier network architecture, not only proposes and implements the scheme of an expert system shell based on programming in Asp.net(c#) associated with Prolog,but also designs and realizes an web-based crane expert system of the testing and training based on the detailed design requirements.The thesis has made an introduction from systematic composition,function,key technology and implementation method adopted.The thesis realizes the integration of the management information system and the expert system of the operation failure analysis.The network deign is implement by ASP.NET.The database and knowledge database is designed by SQL Server 2005,and the database accessing is implement by ADO.NET.The expert system reasoning is realized by amzi! Prolog,may play to the functions of the prolog logic reasoning.The network security of the system is discussed and designed.Finally,the system is operated within the LAN network.The result proved that the system is effective and the structure of the system is reliable.It provides a convenient,fast and efficient approach for developing the web-based expert system.Not only has this system some theoretical significance,but also has broadly practical value.
