| 摘 要： | 在对产品设计知识应用特征分析的基础上，研究了支持设计知识建模的任务结构模型及建议－评估－修改方法，和支持标准型、变型及系列产品设计知识的统一产品设计任务分解结构（用树状与或图表示）。提出了4层结构的产品设计知识模型，实现了多种知识表示方法下复杂产品设计知识的分层与分类表示。为解决设计知识获取问题，设计了产品设计知识获取工作表，对设计知识进行了规范说明和瓶颈分析。最后，建立了路面摊铺机设计知识模型。

| 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. |
