摘　　要：针对属性值为区间数的多专家多属性群决策问题,首先,给出了一个度量区间数相似度的新公式,然后研究了相似度一些优良的性质,提出了一种基于相似度的区间数群决策方法,并给出了决策的具体实施步骤.该方法利用OWA算子集结群体专家意见,通过各方案与正、负理想方案的比较,实现对决策方案的排序.最后,通过算例分析验证了该方法的可行性和合理性.This paper studies the multi-expert multi-attribute problem with interval numbers.It proposes a new formula for similarity degree of interval number and discusses the desired properties of similarity,which leads to a group decision-making method based on similarity of interval numbers.The paper also provides the specific procedures for the decision-making,in which the opinions from experts are summed up through OWA operator and alternative ranking is realized by comparing the alternatives with positive and negative ideal schemes.Finally,the feasibility and rationality of the proposed method is tested in a case study.
