“…Among them, GSA is the most potential in engineering applications, and the indicators can also be called uncertainty importance measures [13] which have attracted lots of research interest in the literature. At present, a number of SA techniques with only aleatory uncertainty, such as a variancebased importance method [14][15][16][17][18][19] for single output or multiple output under a statistic or stochastic process, transformation invariance property and kinds of the moment-independent importance measures [20][21][22][23][24][25][26][27][28], the elementary effect method and the corresponding applications [29,30], the derivative-based method [31,32], the regional analysis techniques and their evolutions [33][34][35][36] and the parametric method [37][38][39], have been developed by different researchers. However, it is also essential for analysts to measure the contribution of distribution parameters to the probabilistic response such as the expectation function, standard deviation function and failure probability function (FPF) of the model output.…”
