摘　　要：方案设计是产品设计过程中的关键阶段,为了有效地重用已有设计中蕴含的设计知识和设计经验,提出了可拓关联规则挖掘与重用的方法。引入了可拓学理论,通过基元对设计知识进行了形式化的描述,基于基元的蕴含性建立了产品设计过程的基元蕴含模型,提出了一种改进的FP-growth关联规则挖掘算法,对产品实例库进行了可拓关联规则挖掘,建立了基于可拓关联规则推理的知识重用模型。最后以某水轮机的选型方案设计为例验证了该方法的可行性和有效性。Scheme design is the key stage of product design process. To reuse the design knowledge and the design experience implicated in the existing design, a method of extension association rule mining and reuse was proposed. This method introduced extension theory; the design knowledge was formally described with basic element; the bas- ic element implication model of product design process was established based on its implication ; a kind of improved FP-growth algorithm of association rule mining was proposed; extension association rules were mined from product case library; a knowledge reuse model based on extension association rule reasoning was established. Finally, the feasibility and efficiency of the method were verified by an example of hydraulic turbine scheme design.
