针对Borgonovo基本输入变量重要度中概率密度函数积分不易求解的缺陷,基于重要度定义将范数的概念引入灵敏度分析中的重要度排序分析领域,提出一种新的基本输入变量重要度排序的计算策略,并为该计算策略选择了若干等价范数,从而避免求解积分的困难.该方法将所求积分用其等价范数进行替代,同时采用适用性更加广泛的一种正则化基本输入变量重要度的计算方法.从理论上讲,该计算策略能够为重要度排序计算提供多种等价范数形式.从所提计算策略与Borgonovo方法、Liu方法的比较可以看出：所提方法是三种方法中最简单有效的.最后,给出两个算例来说明所提方法的可行性.

The probability density function integral of Borgonovo input uncertainty importance measure is hard to calculate.Hereby based on the definition of the input uncertainty importance measure,the concept of norm is introduced into the uncertainty importance ranking analysis for the first time,and a new importance ranking computational strategy is developed,for which some equivalent norms are selected. This strategy replaces the integral by its equivalent norm,and introduces a kind of regularization computing method for uncertainty importance measure at the same time,which has more applicability.Theoretically, this strategy can provide many kinds equivalent norms for estimating the uncertainty importance ranking. Comparisons of present work with Borgonovo method and Liu method subsequently show that the new method is the easiest one.Finally,two examples are illustrated the feasibility of the present work.
