不完备灰色信息系统属性约简

Attribute reduction of incomplete gray information system

在研究分析灰色信息系统中灰数、灰相似度的基础上,定义了改进型灰色相似关系,建立了灰色粗糙集模型的一种扩展模型,给出了不完备灰色信息系统的处理过程和对象数据筛选算法,提出了一种灰色信息系统的属性约简算法,并通过算例进行了验证分析。

Based on the research and analysis of the grey number and grey similarity in grey information system, the improved grey similar relationship is defined, and a kind of extended model grey rough set model is established. And then, the handle process of the incomplete grey information system and the algorithm of the object data selection are given. A kind of the attribute reduction algorithm to the grey information system is proposed and verified through the example in the end.
