基于数据库的专家系统设计

The Design of Expert System Based on Database

该系统属于基于规则的产生式系统,系统采用关系模式来描述知识库,用数据库方法存储管理知识库,以改善知识库的性能,克服专家系统不能有效地利用现有知识库的局限。该系统由以下几部分组成:诊断模块,咨询模块,分析模块和帮助模块等。同时,还建立了咨询知识库和缺陷图形库。为将来对系统的进一步开发打下了良好的基础。

The system is a rule-based production system.An approach to design knowledge base of expert system is used in the system.We describe a knowledge base by relation schema and use the database method to store and man-age the knowledge base,to improve the property of knowledge base management ,and to surmount the limitation of which an expert system can not use knowledge base effectively.The system consists of several parts:diagnosis module,consult module,analysis module an d help module.We also build up a consult knowledge base and a fault picture base.It establishes the basis for further programming of the system.
