铸件孔、洞类缺陷分析的CCDAI专家系统

“Expert System”for Analysis of Casting Porosity Defects

CCDAI是一个基于知识推理的专家系统,它用于分析铸件内部的不健全程度。该系统由五个部分组成:知识库、推理机、知识库、维护模块。解释模块及自学习模块。知识库由产生式规则及命题表构成。推理机采用不精确推理、目标驱动和深度优先搜索策略。应用实例表明我们开发的本软件是可行的。

An “expert System” has been developed to identify casting unsoundness. There are five components in the system: knowledge base, infereuce eugine. Knowledge acquisition module, user interface and self-learning module. The knowledge base consists of produetional rules and parameters-base. Inexact reasoning, Back ward chaining and depth first search formed the control strategy,It has been proved that this software is successful and gains acceptance in the foundry.
