| Abstract: | For the uncertainty measure of a kind of covering rough fuzzy set, we first analyze the physical meaning of uncertainty. 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 covering rough fuzzy sets objectively, and provides a method for the quantitative analysis of uncertainty. |
