Abstract:

Because the current expert systems only support once diagnosis, without double or multiple diagnosis, in this paper, the model of a reproductive disease diagnosis expert system is proposed with the webbased design requirements of reproductive disease diagnosis, which is based on secondary diagnosis, certainty factors and weighted uncertain reasoning. The basic principle and key technologies of the expert system are  discussed in detail, including system structure, function, knowledge base, the design and realization of the reasoning machine, and so on. The practice shows that the expert system features high stability and accuracy.
