| 摘 要： | 产品概念设计是一种创造性的活动，它是一个产品方案形成和方案优化的过程。概念设计一直是产品并行开发中的瓶颈问题。该文介绍基于实例推理的产品概念设计系统。基于所提出的实例模型概念，根据设计要求和产品的特征，建立产品的实例模型。采用面向对象技术描述实例，建立产品实例库。基于设计要求和实例模型进行实例推理，获得的产品设计的相似实例，基于设计和制造的知识对产品的相似实例进行评价与修改，进而获得产品概念设计的优化解。该系统可对北京第一机床厂的定梁龙门铣床的六类进给箱进行概念设计，实际应用表明，基于实例模型的实例推理方法可提高实例推理的效率。

| Abstract: | Product conceptual design is an innovative activity that is to form and optimize the projects of products. It is a bottle neck problem in the process of product concurrent design. This paper introduces a case based reasoning product conceptual design system. Case model has been established according to the design requirements and the features of products. The case is described based on object oriented and the case library is built. Product conceptual design can be carried out by means of case based reasoning based on case model according to user requirements. Product similar case can be evaluated based on the knowledge of design and manufacturing, so the optimum solution of product conceptual design can be acquired. This system has been used successfully in design of six types of feedboxes of Beijing No.1 Machine Tool Plant. The efficience of case based reasoning can be improved dramatically based on the case model. |
