| 摘 要： | 本文首先基于区间二型梯形模糊数的周长、面积、负指数距离提出了一种新的区间二型梯形模糊相似测度,讨论了其性质。其次,基于该相似测度公式分别构建了区间二型梯形模糊专家权重和属性权重确定模型,然后通过集结区间二型梯形模糊决策信息与权重信息,给出了一种基于该相似测度的群决策方法。最后,通过投资方案选择实例说明了该方法的合理性和有效性。

| Abstract: | A new interval type-2 trapezoidal fuzzy similarity measure is proposed on the basis of the perimeters, areas and negative exponential distances of the interval type-2 trapezoidal fuzzy numbers, and then some desirable properties of the new similarity are investigated. Moreover, two models to determine interval type-2 trapezoidal fuzzy expert weights and attribute weights are constructed by using the new similarity measure. Furthermore, a new fuzzy multiple attribute group decision making approach is presented based on the new interval two trapezoidal fuzzy similarity measure . In the end, an example is given to show the rationality and effectiveness of the proposed method. |
