中文摘要：

针对属性权重信息完全未知的直觉模糊多属性决策问题进行了探究,提出了一种综合考虑隶属度、非隶属度以及犹豫度的新的得分函数,利用改进的得分函数将传统的熵权法推广到直觉模糊领域,为属性权重完全未知的直觉模糊多属性决策问题提供了一个新的排序方法.实际的铁路冻害整治算例进一步说明该方法的可行性和有效性.

英文摘要：

Intuitionistic fuzzy multi-criteria decision-maKing approacn wnn unknown welgnt is investigated. A new score function is defined based on membership degree, non-membership degree and hesitancy degree. As for intuitionistic fuzzy multi-criteria decision-making problems in which criteria weights is unknown, an intuitionistic fuzzy multi-criteria decision-making approach is proposed based on the prospect score function and entropy-weighted method. Finally, an illustrative example is given to show the feasibility and effectiveness of this approach.
