区间数的几何平均排序函数及其应用

Geometry Average Sorting Function about Interval Number and Its Application

从数学和实际应用的角度出发,提出了关于正有界闭区间数的一种排序函数——几何平均排序函数,并给出了此函数的相关性质及相应的可信度概念,最后利用模糊综合评判方法进行了具体的实例分析,验证了几何平均排序函数的合理性.

From the point of mathematics and application,we put forward a new geometry average sort function which is used for comparing magnitude of the interval number.Not only we give a few properties of the sort function but the conception of confidence level.Finally,it is rational that the sort function is proved by analyzing an example who uses the fuzzy comprehensive evaluation method.
