基于不确定语言的EDAS决策方法

EDAS Decision Method Based on Uncertain Language

探讨基于不确定语言信息的EDAS决策方法.首先计算平均方案,然后对两个不确定语言变量进行比较,再依据EDAS方法的思想,确定各方案与平均方案的距离值.把距离值综合,得出综合评价值,用以对方案进行排序.最后通过案例表明该决策过程以及方法的有效性及合理性.

This paper discusses the EDAS decision-making method based on uncertain linguistic information.Firstly,the average scheme is calculated,and then two uncertain linguistic variables are compared.Then,according to the idea of EDAS method,the distance value between each scheme and the average scheme is determined.By synthesizing the distance values,the comprehensive evaluation value is obtained,which can be used to rank the schemes.Finally,a case study shows the effectiveness and rationality of the decision-making process and method.
