基于实时数据库技术的HAZOP专家系统框架设计

The design of HAZOP expert system framework based on the real-time database

首先简要介绍了专家系统的基本概念和组成,然后分析确定了HAZOP专家系统的功能及结构。设计指出了HAZOP专家系统包含八个组成部分:用户界面、知识库、实时数据库、推理机、人机接口、系统数据库接口、知识获取机制和解释机制,并着重从知识库、实时数据库和推理机三个部分讲述专家系统的详细设计情况。其中知识库的设计包括知识库的表示与组织、知识库的管理两个方面,接着提出实时数据库的设计思想并进行框架结构设计,最后采用正向推理方式实现推理过程。

This paper introduced the basic concept and composition of expert system. Then the function and structure of HAZOP expert system were analyzed and determined. According to the component of system, there were eight parts which consist of user interface, real-time database, knowledge database, inference machine, human machine interface, system database interface, knowledge acquisition mechanism and explanation facility. The realtime database, knowledge database and inference machine were emphasized to focusing on design of expert system in detail among these aspects. The knowledge database was composed of knowledge organization and management. With that the real-time database was put forward and the frame structure was designed on the basis of thought. At last, the way of the forward reasoning was used for process.
