摘　　要：在多粒度粗糙集的基础上,结合粒度选择和分类选择的不确定性建立基于β-相似关系的广义多粒度粗糙集模型。该模型在一定程度上弥补了多粒度粗造集模型粒度选择和分类选择的局限性。讨论基于β-相似关系的广义多粒度粗糙近似算子的性质以及与多粒度粗造集模型的关系。通过案例验证了该模型的应用实效。Based on the multi-granulation rough set theory,a generalized multi-granulation rough set model based onβ-similarity relation is established by combining the uncertainty of granulation selection and classification selection.The model made up for the limitations of granulation selection and classification selection of multi-granulation rough set model.The properties of generalized multi-granulation rough approximation operator based onβ-similarity relation and its relationship with multi-granulation rough set model were discussed.A case was used to verify the application effect of the proposed model.
