摘　　要：针对一种覆盖粗糙模糊集的不确定性度量,分析了不确定性的物理含义,给出了一种基于模糊贴近度的度量方法,进而对其性质进行了分析。结果表明该度量方法能客观反映粗糙模糊集不确定性的程度,从定量的角度为刻画粗糙模糊集的不确定性提供了方法。For the uncertainty measure of a kind of coveting rough fuzzy set, we first analyze the physical meaning of uncer-tainty. Thus, an uncertainty measure based on fuzzy similarity measure is developed, and its properties are studied. The results indicate that this measure can reveal the uncertainty of coveting rough fuzzy sets objectively, and provides a method for the quantitative analysis of uncertainty.
