通过对区间直觉模糊数的犹豫区间进行讨论,提出了区间直觉模糊数的新得分函数和精确函数,并讨论新的得分函数具有的性质,在此基础上给出了区间直觉模糊数的一种新的排序方法。进而,结合区间直觉模糊加权平均算子给出了属性值为区间直觉模糊数的多属性决策方法,并通过算例阐明该方法的可行性和有效性。
By discussing the hesitancy interval of interval intuitionistic fuzzy numbers, the new score functions and exact functions of interval intuitionistic fuzzy numbers are proposed, and the properties of the new score functions are discussed. Based on this, a kind of interval intuitionistic fuzzy numbers New sorting method. Furthermore, a multi-attribute decision-making method is proposed based on interval intuitionistic fuzzy weighted average operator, whose attribute value is interval intuitionistic fuzzy number. The feasibility and validity of this method are illustrated through examples.
