摘要
定义了区间直觉模糊集的加权算子和加权几何集成算子,介绍了现有的区间直觉模糊集的得分函数和精确函数.定义了一个新的精确函数,此函数弥补了已有函数的不足和缺陷,应用新定义的精确函数,提出了对区间直觉模糊集多属性决策问题进行决策的方法.最后以应用实例对该方法进行说明和验证.
The interval-valued intuitionistic fuzzy weighted arithmetic average operator and interval-valued intuitionistic fuzzy weighted geometric average operator are defined. The score function and accuracy function for interval-valued intuitionistic fuzzy sets are introduced. A new accuracy function is defined. It overcome the defect of exiting accuracy functions and score functions. Based on the new accuracy function, a multicriteria fuzzy decision-making method for interval-valued intuitionistic fuzzy sets is presented. Finally, an example is used to illustrate the feasibility and effectiveness of the presented method.
