摘　　要：介绍了Vague集与Fuzzy集的特点,结合Vague集理论及投票模型下的解释,对Vague集向Fuzzy集转化的多种方法进行了分析,指出已有方法的不足,根据Vague集的三维特性并结合人的心理变化情况首次直观地提出一种新的有效非线性方法,并通过实例说明该方法的正确性和直观性。The features of Vague sets and Fuzzy sets are introduced.Based on theory of Vague sets and voting model,several methods for transforming Vague sets into Fuzzy sets are analyzed,and problems of the existing methods are pointed out.Finally,according to three-dimension characteristics of Vague sets and combined with the psychological changes in people,a new nonlinear method of effectiveness is presented intuitively,and its correctness and intuition are explained by taking examples.
