摘要
基于模糊等价关系,在模糊概率空间上利用模糊条件概率建立了概率模糊粗糙集模型.讨论了概率模糊上、下近似算子的性质.最后给出了模糊集的近似精度和粗糙度的计算公式.
In the fuzzy probability space , the probabilistic fuzzy rough set model is established on the basis of fuzzy equivalent relation by means of fuzzy condition probability .The properties of probabilistic fuzzy upper and lower approximation operators are discussed .Finally , the calculation formulas of approximation accuracy and rough-ness measure of fuzzy sets are given .
