| Abstract: | The characteristics of design process, design object and domain knowledge of complex product are analyzed. A kind of knowledge representation schema based o n integrated generalized rule is stated. An AND-OR tree based model of concept f or domain knowledge is set up. The strategy of multilevel domain knowledge acqui sition based on the model is presented. The intelligent multilevel knowledge acq uisition system (IMKAS) for product design is developed, and it is applied in th e intelligent decision support system of concept design of complex product. |
