摘要
本文基于文献[4]提出的广义多粒度粗糙集进行模型推广,提出广义多粒度变精度粗糙集模型.在多粒度的粒度不确定性的基础上考虑类选择的不确定性,研究新模型的一些基本性质并以实例计算说明.本文给出的广义多粒度变精度粗糙集为多粒度粗糙集理论的研究和应用奠定一定的理论基础.
In this paper, we study a generalized multi-granulation variable precision rough set model which is proposed from Reference [4]. Uncertainty of classifications are considered with the uncertainty of multiple granulations. Some basic properties of the new model are approached and an example is supplied to explain the contents researched. The generalized multi-granulation variable precision rough set approached in this paper can lay the theoretical foundation for research and applications of variable precision fuzzy rough set.
