基于3M特征的设计知识表达模型
Design knowledge representation model based on 3M features
摘要
Abstract
Aiming at the problem that knowledge for supporting innovative design was classified representation and management,and lack of unified knowledge representation and management model,a kind of unified knowledge representation and management method based on 3M (multi-attribute multi-dimensional multi-hierarchy) features was put forward .According to the knowl-edge demand for innovative design,knowledge attributes were divided into innovation attributes and basic attributes .The innovation attributes were the abstraction of knowledge and realized multi attribute correlation between knowledge,including the function,input and output flow, TRIZ principle,field attributes of knowledge .The basic attributes were the specific description of the physical attributes of the multidisciplinary knowledge,including the background,function, principle,and structural attributes .With the establishment of knowledge representation template based on the unified framework of knowledge innovation attributes and basic attributes,the com-prehensive representation and cross transferring of different types of knowledge could be realized, and the corresponding knowledge base prototype system was constructed .The application process of the knowledge repository was demonstrated by the example of the improved design of the nu-clear reactor under stack structure,which indicated that this knowledge model could represent and manage design knowledge uniformly,and could assist designers with knowledge search and application in innovative design effectively .关键词
