To solve the problem of complex computing and classifying of patterns in fault diagnosis, a fractal fault-tolerant diagnosis method based on roughreduction is presented.
针对故障诊断中计算量大，模式分类复杂的问题，提出了一种基于粗糙集的分形容错故障诊断方法。

Reduction and core are two important concepts and significantly applied in rough set.
约简与核是粗集中的两个重要概念，它具有重要的应用。
