灰色信息系统中的优势粗糙集模型

摘要

文章将一种新的优势关系引入到区间集灰色信息系统中，定义了对象灰度与对象确定度、整体灰度与整体确定度等概念，建立了基于优势关系的粗糙集模型，由此得出一系列相关性质与定理，最后用一实例进行了说明。%A new set of dominance relation is introduced into the interval sets of gray information systems. Concepts such as gray of the object, the degree of certainty towards the object, the overall gray and the overall degree of certainty are defined. A rough set model is presented based on the relationship of dominance, based on which a series of related properties and theorems can be harvested. Finally, an illustrate example is discussed.
