机械设计专家系统的知识表示

The Knowledge Representation of Mechanical Design Expert System

知识表示是机械设计专家系统(MDES)的核心问题之一。本文在分析机械产品设计过程和知识特点的基础上,结合传动箱设计专家系统——GBES的研制,提出了知识元、规则、过程、向量、表等的综合知识表示方式和相应的知识库结构及维护手段。GBES用SCheme Lisp语言编写,已在IBM PC/AT机上成功运行。

The knowledge representation is one of the key problems of mechanical design expert system(MDES). The composite knowledge representation approach to knowledge unit, rule, procedure, vector and list,and the structure and the maintenance means of knowledge base are presented in this paper, on the basis of analysing the design process and the knowledge characteristics of mechanical products,and combining the research of Gear Box Expert System------GBES, GBES is written in Scheme Lisp,It has, run, successfully on an IBM RC/AT computer.
