为了解决具有不确定性区间数的多属性决策问题，本文给出了一种分析方法．首先是基于文献［５］，介绍了一个决策分析模型；然后针对以区间数形式表示的决策方案综合评价值，提出了关于区间数优势及可能度的概念，并且相应地给出了带有可能度的方案排序方法，这也是本文的重点内容．最后，给出了实例计算 In order to solve the multi-attribute decision making problem with uncertain interval number, this paper gives an analysis method. Firstly, a decision analytic model is introduced based on the literature [5]. Then, the concept of the advantages and possibilities of interval numbers is proposed for the comprehensive evaluation of decision-making schemes in the form of interval numbers. Correspondingly, Degree program ranking method, which is also the focus of this article. Finally, an example calculation is given
