在役压力管道缺陷安全评定专家系统知识库子系统的研究

Study on knowledge base management subsystem of expert system for safety assessment of in\|service pressure pipelines containing defects

研制开发了在役压力管道缺陷安全评定专家系统并在工程中得到实际应用，为压力管道超标缺陷科学处理提供了有力工具。介绍该专家系统的知识库管理子系统的结构和功能。为提高专家系统问题求解速度，作者引入决策表技术构造了一种新型的知识库内结构规则树，使知识库内规则以规则树形式存在，提高了推理速度，本文将详细介绍其实现方法。

An expert system for safety assessment of in\|service pressure pipelines containing defects developed by authors has been used in engineering. In this paper, the structure and function of the knowledge base management subsystem of the expert system are briefly described. In order to raise the problem solving speed of the expert system, decision table technique is introduced to build a new type of knowledge base rules tree, in which the rules exist in binary tree structure. The built method is described in detail.
