【Abstract】 For investment decision-making problems which use intuitionistic trapezoidal fuzzy numbers to express evaluation information, this paper defines the expectation of intuitionistic trapezoidal fuzzy numbers based on its geometric characteristics. Combined with the integration operator of intuitionistic trapezoidal fuzzy numbers,this paper proposes a method of intuitionistic fuzzy investment decision-making that based on information. The feasibility and effectiveness of the method are illustrated by an example.更多还原
