支持性能驱动设计的产品性能表达

从性能需求驱动产品设计思想出发，研究支持产品设计的知识资源的基础建设问题。提出产品性能元概念，并采用面向对象方法定义了性能特征类，达到对已有产品按性能进行分类存储的目的。最后讨论了面向对象的定义对后续的由性能需求到产品结构特征和制造特征的映射研究的意义。

Representation of Product in Performance-Driven Design

For realizing performance requirement-driven product design, the organization of existing knowledge is very important. A scheme to organize and describe the knowledge of existing products is put forward, in which the concepts of product performance cell is defined. An object-oriented definition and realization of performance features is presented to simplify the extension of product database and carry out the operations such as classification and storage of cases. Performance feature not only connects requirements of consumers with the final product design, but also makes it possible to reuse knowledge of existing products and their ways of design in the future works.
