基于新期望值的直觉模糊投资决策方法

An intuitionistic fuzzy investment decision-making method based on newly defined expectation

针对采用直觉梯形模糊数表达评价信息的投资决策问题,依据直觉梯形模糊数的几何特征定义其期望值,结合直觉梯形模糊数的集成算子,提出一种直觉模糊投资决策方法,并通过算例说明方法的可行性和有效性。

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.
