摘　　要：多粒度粗糙集的研究是近几年来研究的热门课题之一。提出了一种介于乐观和悲观多粒度软粗糙集的新模型——程度多粒度软粗糙集。首先,通过计数函数建立了程度多粒度软粗糙集模型;其次,讨论了程度多粒度软粗糙近似算子的性质;再次,定义并研究了程度多粒度软粗糙集的不确定性度量及性质;最后,通过医院对病人诊断的案例验证了模型的实用性。In recent years,the research on multi-granulation rough set has become one of the hottest researches.In this paper,a new model of the grade multi-granulation soft rough set is presented,which is between optimistic multigranulation soft rough set and pessimistic multi-granulation soft rough set.Firstly,the grade multi-granulation soft rough set is established by count function.Secondly,the properties of approximation operators are studied.What's more,the uncertainty measure of grade multi-granulation soft rough set is defined and the properties are studied.Finally,an example diagnosis of patient in hospital illustrates the feasibility of this model.
