专家系统的结构及其在铁路上的应用

Structure of Expert System and Its Application in Railway

专家系统是人工智能研究领域中最成功的一个分支，确定专家系统的结构是构造专家系统过程中非常关键的一步，作者在文中提出和分析了专家系统的三种结构：专家系统的基本结构、专家系统的流行结构、专家系统的理想结构，对每一种结构都做了详细的描述，为构造专家系统提供了一条捷径。并在原铁路路基病害诊断专家系统的系统结构基础上提出了铁路路基病害诊断专家系统的理想结构。

Expert System(ES) is a most successful branch in the research of the Artificial Intelligence(AI). Deciding the characteristics of the structure of the studied ES is a critical step. In this paper,three structures,i.e.the basic, the popular and the ideal structure of ES are presented,and each of the structures is analysed in detail. All of these offer an express way to ES.Based on the existing structure of ES for railway subgrade defect diagnosis,an ideal structure of ES for railway subgrade defect diagnosis is presented.
