摘要
In order to apply the knowledge based engineering to solve the low efficiency of serialized design,by analyzing the top-down design characteristics,a composite representation method for the design knowledge is proposed.The object-knowledge is expressed by framework,and the construction principles of the framework are given,the design knowledge element is used to express the process-knowledge.Then the knowledge reasoning model for design decision-making is established.Finally,a case shows that the proposed method and model are effective.
