Shu‐Ping Wan · Kongzhi yu juece · 2011
Interval-valued intuitionistic trapezoidal fuzzy number is investigated.Some operational laws of interval-valued intuitionistic trapezoidal fuzzy numbers are defined and some related properties are researched,the weighted arithmetic average operator and weighted geometric average operator for the interval-valued intuitionistic trapezoidal fuzzy numbers are given.The score function and accurate function of intuitionistic trapezoidal fuzzy numbers are defined,and then an approach for ranking interval-valued intuitionistic trapezoidal fuzzy numbers is presented.The model of multi-attribute decision making is constructed based on interval-valued intuitionistic trapezoidal fuzzy numbers.The corresponding method of decision making is proposed.The example analysis shows the effectiveness of the method.
