摘　　要：针对特征取值为区间数的方案排序问题,提出两个区间数的偏离度概念用以构造方案间的偏离度矩阵,并给出一种基于总体偏离度优化的特征权重确定方法.利用提出的区间数向量的相对贴近度概念刻画一个方案接近于另一个方案的程度,进而对候选方案的优劣排序.该方法提出的各种度量较直观、易于理解,并通过实例验证方法的有效性和实用性.For the alternative ranking problem with deviation degree of two interval numbers is alternatives and a method to determine wei proposed as well in this paper. By using ght the attribute values being interval numbers, the concept of presented to construct the deviation degree matrix for vector based on the total deviation degree optimization is proposed concept of relative closeness degree of interval number vectors, the degree of an alternative close to another is depicted, and thereby the merit of alternatives are ranked. The proposed measures of this method are intuitive and easy to understand, and an illustrative example is employed to demonstrate its feasibility and practicability.
