实例推理方法在机械产品方案设计中的应用

Case-based reasoning for mechanical product alternative design

机械产品方案设计是产品设计过程中最关键的设计阶段.提出基于实例推理(Case-Based Reasoning,CBR)的方案设计过程,论述了实现推理的关键技术:实例表示、实例检索和实例修正;从基于实例的产品方案设计过程的研究、CBR与其他推理方法的综合应用以及CBR与创新设计方法的结合3个方面探讨了CBR技术在机械产品方案设计中的主要应用.

The alternative design for mechanical products is the most vital phase in entire design process.Based on the case-based reasoning（CBR） technique,the alternative design procedure,together with enabling techniques,is postulated in terms of case representation,retrieval and revise.Furthermore,the applications of the CBR technique for mechanical product alternative design are presented based on the integrations with other reasoning techniques and innovative design methodologies.
