摘要:
将任意两个区间数在数轴上的可能位置关系粗略划分为13种情形,并从确定性角度和基于度的角度出发,详细分析了目前已有的区间数排序方法及其相互关系。提出一种综合考虑数据的均匀性和分散性,并具有明显度量特性的区间数排序方法。

Abstract:
Interval number has been an effective method dealing with uncertain variables in engineering and decision-making fields. But the method of ranking interval numbers should be solved first for their widespread use. Roughly, there are thirteen possible position relations of any two interval numbers in real axis, which are illustrated in this paper. The ranking methods of interval numbers and their correlations are labored from both the point of certainty and the point of degree-based. Finally, a new ranking method for interval numbers, which synthesizes the uniform and dispersity of data, is presented.
