摘要
模糊数直觉模糊集是直觉模糊集和区间数直觉模糊集的拓展,本文提出了二型直觉模糊数概念,对基于二型直觉模糊信息的多属性决策进行了研究。以结构元理论为基础,给出了二型直觉模糊数的距离公式,然后定义了二型直觉模糊正、负理想点,进而给出了一种基于二型直觉模糊数的多属性决策的步骤。最后通过实例来证明其有效性。
Fuzzy number intuitionistic fuzzy set is the development of intuitionistic fuzzy set and interval number intuitionistic fuzzy set. In this paper, 2-type intuitionistic fuzzy number is put forward and the 2-type intuitionistic fuzzy multiple attribute decision making is studied. Based on fuzzy structured element theory, the distance between 2-type intuitionistic fuzzy numbers is given. The concepts of 2-type intuitionistic fuzzy positive-ideal point and 2-type intuitionistic fuzzy negative-ideal point are defined. Then a method for multiple attribute decision making with 2-type intuitionistic fuzzy numbers is developed. Finally, an example is given to verify the effectiveness of the developed method.
