基于知识组件的产品设计知识重用方法研究

Knowledge Reuse in Component-based Product Design

【目的】促进产品设计活动中设计知识的重用,提高产品设计效率。【方法】根据产品设计活动中知识重用需求,进行知识组件的结构分析,提出基于知识组件的产品设计系统框架,结合计算机组件技术进行知识组件的设计实现研究。【结果】以身管产品为研究对象,构建身管产品的知识组件,设计并实现基于知识组件的身管设计系统。【局限】开发的知识组件具有一定领域局限性,仅适用于相同产品或结构相似的同类产品,知识组件的通用性、系统的移植性和知识的迁移性还有待进一步验证。【结论】基于知识组件的方法可以有效地实现产品设计知识的重用。

[Objective] To promote the knowledge reuse in product design and improve its efficiency. [Methods] First, we analyzed structure of the knowledge components in accordance with the knowledge reuse requirements of product design activities. Second, we proposed a framework for product design system based on knowledge components. Finally we implemented the reuse of knowledge components with the help of related computer programs. [Results] We constructed the knowledge components for barrel products, and then established a designing system based on the new knowledge components. [Limitations] The new system had certain limits, and could only be applied to the same or similar products. More research is needed to examine the universality of the knowledge components, the adaptability of the system, as well as the transferability of knowledge. [Conclusions] The new system based on knowledge components could effectively reuse the product design knowledge.
