摘要
为了在一定程度上提升模型的实用性与容错率,首先给出程度模糊粗糙集模型和局部程度模糊粗糙集模型的定义,然后,将局部模糊粗糙集模型与局部程度模糊粗糙集模型通过逻辑联结词结合起来,提出局部双量化模糊粗糙集模型,并给出模型的相应性质.最后,通过一个相应的例题说明其有效性.
In order to improve the practicability and fault tolerance of the model to a certain extent,firstly,the definitions of graded fuzzy rough set model and local graded fuzzy rough set model are given,and then the local double-quantitative fuzzy rough set model was proposed by combining the local fuzzy rough set model and local graded fuzzy rough set model by logical connectives.Secondly,the corresponding properties of the model are given,Finally,a corresponding example is given to illustrate the validity of the model.
