对基于区间直觉模糊信息的多属性决策问题进行了研究。给出了区间直觉模糊数之间的距离公式,并定义了区间直觉模糊正、负理想点,进而提出了一种基于TOPSIS的区间直觉模糊多属性决策方法。最后进行了实例分析。
The mukiple attribute decision making problems with interval-valued intuitionistic fuzzy information are investigated. The formula for measuring the distance between interval-valued intuitionistic fuzzy numbers is given, and the concepts of interval-valued intuitionistic fuzzy positive-ideal point and interval-valued intuitionistic fuzzy negative-ideal point are defined. Then a TOPSIS method for multiple attribute decision making with interval-valued intuitionistic fuzzy information is developed. Finally, an illustrative example is given.
