Abstract: Based on theory of Vague sets and voting model，some methods of transforming Vague sets into Fuzzy sets are introduced，and some problems of these methods are pointed out.On the basis of these methods，a new method is presented，and some instances show that the method is more reasonable than other existing methods.

摘要： 基于Vague集理论及投票模型下的解释，介绍了Vague集向Fuzzy集转化的一些方法，并指出了这些方法的不足，在此基础上提出了一种新的转化方法，并证明了该方法的有效性，实例表明该方法比已有的方法更合理。
