基于概率语言和区间数的多属性决策TOPSIS方法及其应用

TOPSIS method for multi-attribute decision making based on probabilistic language and interval numbers and its application

多属性决策过程中为了解决候选方案的评价信息表现为概率语言术语集和区间数情形的问题,相应模糊信息的处理过程成为决策关键.在构建概率语言术语集和区间数的序关系和距离测度基础上,改进TOPSIS多属性决策方法,以适应具有混合形式模糊决策信息的多属性决策过程,一个算例分析说明了所提出的改进TOPSIS方法的实用性和普适性.

In the process of multi-attribute decision-making, in order to solve the problem that the evaluation information of candidate schemes is expressed as probabilistic language term set and interval number, the processing of corresponding fuzzy information has become the key of decision-making.On the basis of constructing the order relation and distance measure of probabilistic language term set and interval number, the TOPSIS is improved to adapt to the multi-attribute decision-making process with mixed fuzzy decision information.An example shows that the improved TOPSIS method is practical and universal.
