摘　　要：基于区间数的相对优势度,提出了区间直觉模糊数的相对优势度概念。通过构建区间直觉模糊数比较的相对优势度矩阵,结合基于互补判断矩阵的排序公式,给出了一种区间直觉模糊数的排序方法,并将此排序方法应用到属性权重未知的区间直觉模糊多属性决策当中。通过算例分析说明了该方法的有效性和可行性。Based on the relative superiority of interval numbers, the definition of relative superiority of interval-valued intuitionistic fuzzy set （IVIFS） was proposed. And then, a ranking method combined with the priority formula was obtained by establishing a relative superiority matrix of IVIFS. Furthermore, this method was applied to multi-criteria fuzzy decision making with unknown attribute weight information, in which criteria values for alternatives are IVIFSs. And finally, an illustrative example was given to demonstrate the developed method and to show its validation and practicality.
