Abstract:

This paper presented a task-structure modeling and a PCM (propose-critique-modify) method for product design knowledge modeling, based on analysis of application characteristics of product design knowledge. A united product design task decomposing structure for standard products, optional products and series products was proposed, and was figured with an tree and/or chart. A knowledge model of four layers structure was presented, by the model, knowledge can be organized at hierarchical classification, and expressed with different forms of knowledge. The paper also designed a working-sheet for acquiring design knowledge, it helps to unify knowledge acquiring and knowledge bottleneck analysis. A case-road pavers design knowledge model was presented herein.

Key words: product design knowledge, knowledge model, task structure, propose-critique -modify, knowledge acquiring
