| Abstract: | The process characteristics of the complex product design and the resolvability of the design goal in intelligent CAD systems are analyzed. The immanent relationship between the design sub-goals and the sub-knowledge bases is discussed. The model of hierarchical knowledge representation and knowledge base is set up based on the control of meta-knowledge and the guiding of hierarchical framework. The strategy of intelligent multi-level domain knowledge acquisition is presented based on the model of and/or tree of concepts. |
