A New Knowledge Modeling Method for Product Design

Abstract

The representation and organization of knowledge is the core of key technologies of artificial in- telligence, and the modeling of design knowledge is an important and difficult step in developing intelligent designing system. The Design-Mode-Oriented Model (DMOM) used in representation of design knowledge was proposed in this paper. And corresponding to DMOM, three object design models, named as function model, parametric model and case model were also proposed to represent the knowledge of object design. The information gathered from users can be classified into three kinds and each of which represents func- tions, technical specifications and types of product respectively. Three design modes were also established by mapping the three kinds of information to corresponding object design models. By using model trans- formation, design information can be processed and the solution of design can be found. This modeling method can be used in the applications of designing for most of electrical and mechanical products.
