带有区间数的多属性决策问题是有关多属性决策研究中的一个重要课题。针对如何计算每个决策方案的综合评价值 ,本文提出了一个新的分析方法 ,它是基于简单加权法则 ,通过建立线性目标规划模型来得到的方案的评价值。本文的方法改进了已有分析方法的不足之处。最后 ,给出了一个算例 Multi-attribute decision making with interval numbers is an important issue in the study of multi-attribute decision making. Aiming at how to calculate the comprehensive evaluation value of each decision scheme, a new analysis method is proposed in this paper. It is based on the simple weight rule, which is obtained by establishing a linear target programming model. The method in this paper improves the deficiencies of the existing methods. Finally, an example is given
