| 摘 要： | 在进行了阐述Vague集的相关概念和运算后,对多目标模糊决策进行了定义,给出多目标模糊决策的基本思路,并对已有的基于Vague集的多目标模糊决策方法进行了分析,得出现有Vague集的多目标模糊决策方法存在着缺陷,从而提出了一种新的多目标模糊决策的Vague集方法,该方法利用一个新的评分函数对方案进行排序,选出最优方案.最后给出其相关性质,证明其解决了现有方法的缺陷,并通过实例阐明本文方法的有效性和优越性.

| Abstract: | After the related notions and operations of Vague sets are presented,multicriteria fuzzy decision-making is defined and basic thinking of multicriteria fuzzy decision-making based on Vague set is posed,while the present methods of multicriteria fuzzy decision-making based on Vague set are analyzed,the faults existing the method of multicriteria fuzzy decision-making based on Vague set are presented.Moreover,a new method based on Vague sets is given,which all alternatives are ranked using a new score function and the best one is selected.Finally,the relevant property of the new method is presented and proved,and the defect of present methods is solved,and the example show that the method is more efficient and advantageous. |
