中文摘要：

研究了基于粗集（RS）理论的产品配置规则获取方法，实现信息约简，产生更简洁、更有意义的规则。给出了数据约简方法，包括建立RS知识模型、RS决策逻辑表示、确定辨识矩阵、计算其核心、进行属性归约、规则形成等内容。结合案例进行了验证，利用RS理论对传动机构总成的配置模型进行约简，可以得出最简化的配置规则，用于产品配置设计。

英文摘要：

The acquirement method of product corffiguration rules is studied based on Rough Set （RS）.Terse and significant rules are expressed through information reduction.lnformation reduction method is given;in which includes RS knowledge modeling,RS decision logic expression,distinction matrix making,cores calculation,attributes reduction,rules generation,etc.Transmission assembly case study is discussed to prove the theory.The configuration model reduction based on RS is put forward and product configuration design hales are discovered.
