Analysis of constraint conditions and measurement method on fuzzy entropy of vague sets
Vague集模糊熵的约束条件及其度量方法分析*

The fuzzy entropy of vague sets should include the unknown and the uncertainty, at first, gave a counterexample to show that the result used the existing method in some cases and practical conclusions were inconsistent, then proposed an improved definition on the fuzzy entropy of vague sets taking really into account two factors that were unknown and uncertainty, and presented a corresponding new measurement on the fuzzy entropy of vague sets. Finally pointed out the unknown and the uncertainty to take really into account simultaneously by theorem proof and example analysis. And then it is proved that the definition on the fuzzy entropy of vague sets is more efficient and rational.
