本文引入了直觉梯形模糊数的期望值概念，给出了直觉梯形模糊多准则决策问题的一种处理方法，其中方案对准则的偏好值和准则的权重值均为直觉梯形模糊数。提出了一种简单而精确的公式来确定备选方案的准则期望权重值和备选方案的加权期望值。因此，期望值方法扩展到排序方案，并可以选择最可取的（S）根据加权的期望值。最后通过一个算例说明了该方法的简单性和有效性。
In this paper, we introduce the expected values for intuitionistic trapezoidal fuzzy numbers and presented a handling method for intuitionistic trapezoidal fuzzy multicriteria decision-making problems, in which the preference values of an alternative on criteria and the weight values of criteria take the form of intuitionistic trapezoidal fuzzy numbers. Simple and exact formulas are proposed to determine the expected weight values of the criteria for an alternative and weighted expected value for an alternative. Therefore, the expected value method is extended for ranking alternatives and the most desirable one(s) can be selected according to the weighted expected values. Finally, an illustrative example shows that the proposed method is simple and effective.
