Study on multi-stage fuzzy multiple attribute decision making based on Vague set

综述了基于Vague集的多属性决策方法,针对现有研究成果存在的不足,提出了基于Vague集的多阶段模糊多属性决策方法,阐述了该方法的基本步骤和实现过程。该方法分阶段对决策方案进行筛选淘汰,找出最佳决策方案,能有效解决现有Vague集排序函数失效的问题。数值实验表明,该方法有很好的求解能力,为基于Vague集求解模糊多属性决策问题提供了一种新的思路和方法。

Multiple attribute decision making theories based on Vague set are reviewed and introduced. Concerning of the shortcomings of existing research methods, a multi-stage fuzzy multiple attribute decision making method based on Vague set is proposed. Basic steps and implementation processes of the method are detailedly presented. Through multi-stage filtering of decision programs, the best decision is gotten, and the method effectively over- comes the common seen failure problem of various Vague set sorting functions. Numerical experiment shows that the method has good solving ability, and it provides a new way to solve fuzzy multiple attribute decision making problems based on Vague set.
