论机械设计知识的混合表示方法

A HYBRID REPESENTATION APPROACH FOR MECHANICAL DESIGN KNOWLEDGE

本文通过分析机械产品方案设计专家知识的类型和特点,在比较现行的各种知识表示方法的优缺点的基础上,提出了一种集框架表示、规则表示和过程表示于一体的混合知识表示方法,并结合“三系列工业汽轮机方案设计专家系统(TDES)”的研制,着重探讨了机械设计专家系统的混合知识表示方法和知识库组织管理两方面的问题。

This paper analyzes in detail the type and feature of mechanical product scheme design knowledge in the view point of applying the AI technology effectively to mechanical design, and compares current all kinds of knowledge representation approaches. Based on the result of the discussion, a hybrid knowledge representation approach including frame representation、rule representation and procedure representation is put forward. In this paper, We will introduce in detail the hybrid knowledge representation approach and the organization of knowledge base with the development of TDES
