介绍了粗糙集理论的基本概念和特点 ,研究了基于概念泛化和粗糙集的数据挖掘算法(CRCG)的决策分析 ,并以拉深模具为例 ,将其应用于模具质量评价和诊断 ,使模具质量控制的决策更科学、合理
The basic concepts and characteristics of rough set theory are introduced. The decision analysis of data mining algorithm (CRCG) based on concept generalization and rough set is studied. Taking deep drawing dies as an example, this method is applied to the evaluation and diagnosis of mold quality. Mold quality control decisions more scientific and reasonable
