摘　　要：针对区间直觉模糊数的排序问题,定义一种新的区间直觉模糊数精确函数。在考虑犹豫度信息的情况下,讨论了该精确函数的性质。通过实例与已有的精确函数比较,结果显示,该精确函数的排序能力有一定程度的提高。最后将其应用到区间直觉模糊多属性决策中,并用实例分析验证该方法的有效性。A new way to define a new accuracy function of interval-valued intuitionistic fuzzy numbers is proposed for sorting the interval-valued intuitionistic fuzzy numbers in this paper. The properties of the function are discussed based on considering the information of hesitancy degree. Some examples are designed and compared with some existing accuracy functions. The results show that the sorting capability of the new accuracy function is improved to the certain extent. At last, this new accuracy function is applied to the multiple attribute decision making on interval-valued intuitionistic fuzzy numbers and its effectiveness is illustrated by a numerical example.
