中文摘要：

给出了Vague集比较的可能度定义,并研究了其所具有的性质。针对属性权重已知和完全未知的Vague集多属性决策问题,应用最优点方案来建立最优化决策模型。应用Vague集间比较的可能度公式,提出了解决Vague集多属性决策问题的新方法。最后以应用实例对该方法进行说明和验证。

英文摘要：

This paper gives the definition of possibility degree between Vague sets.And some properties are studied.The Vague multiple attribute decision-making problems are investigated,in which the information about alternative weights are known or uncertain completely.By using optimal plan,the optimization model is established.Then,based on formulas of possibility degree,a new method is given.Finally,an example is used to illustrate the feasibility and effectiveness of the presented method.
