Abstract: As the characteristics of engineering design are considered, a universal model for designing expert systems is presented. The model is given on the basis of HEARSAY-Ⅲ. The model possesses quite a few new features. By use of the model , the knowledge for designing can be expressed and dealt with easily, and expert systems can be established easily. The designing expert systems basde on the model are able to solve complex designing problems dffdctively. With the model, an expert system foe designing deep-drawing dies is constructed.The performance of the dies proves that this model is effective and practical.

Key words: pert system model, designing expert system, Knowledge representation, Blackboard structure
