基于期望值与宽度的区间数可能度的一种新定义

A New Definition of Possibility Degree for Interval Numbers Based on the Expectation and Width

基于区间数的期望值和宽度,结合已有的区间数可能度公式,给出了一种与之等价的区间数可能度的定义及性质,并利用区间数可能度矩阵给出了排序步骤,最后通过实例讨论了区间数可能度法的简单应用。

According to the expectation and width of the interval number,combined with the existing definition of possibility degree for interval numbers,a new definition of possibility degree for interval numbers is proposed and its properties are researched. Through setting the matrix of possibility degree for interval numbers,the steps of ranking are given and the simple application of the new method for ranking interval is discussed in this paper.
