一种直觉梯形模糊数的排序方法及其在多准则决策中的应用

摘要

According to the characteristic of intuitionistic trapezoidal fuzzy number, a new distance of intuitionistic trapezoidal fuzzy numbers is defined. This paper proposes a new ranking method of intuitionistic fuzzy numbers with the ideal points,which is applied to fuzzy multi-attribute decision making. Also,a practical example is provided to verify the effectiveness of the developed approach.%先根据直觉梯形模糊数的特点,定义一种新的直觉梯形模糊数距离公式,再结合理想点方法,提出一种直觉梯形模糊数的排序方法,最后将该方法应用于模糊多准则决策中,并通过实例说明了所提方法是有效的.
