A New Importance Measure for Sensitivity Analysis

Abstract: Uncertainty is an integral part of risk assessment of complex engineering systems, such as nuclear power plants and space crafts. The aim of sensitivity analysis is to identify the contribution of the uncertainty in model inputs to the uncertainty in the model output. In this study, a new importance measure that characterizes the influence of the entire input distribution on the entire output distribution was proposed. It represents the expected deviation of the cumulative distribution function (CDF) of the mo… Show more

“…Several global sensitivity measures have been proposed [12][13][14][15][16][17]. Among them, the first-order sensitivity index [14] and the total-order sensitivity index [15] are popularly used.…”

“…If the distributions of the model outputs are highly skewed, variance will not be suitable to represent uncertainty. In this case, other sensitivity indices, such as the indicator proposed by Liu and Homma [17], might be suitable.…”

“…Generally, SA can be divided into two main branches [2,3]: local SA and global SA. Recently, global SA is widely investigated and lots of global SA techniques have emerged, such as non-parametric techniques [4], variance-based techniques [5][6][7], and moment-independent techniques [8][9][10][11][12][13]. In References [14,15], Borgonovo and co-workers ascribed the latter two kinds of sensitivity indices to the same rationale and proved some general results according to their properties.…”

“…(10) During the past few decades, a large number of indices have been developed by different researchers for global SA. (11)(12)(13)(14)(15)(16)(17) Among all these SA indices, the variance-based one proposed by Sobol and Homma and Saltelli (11,12) and the moment-independent one (also called delta index) proposed by Borgonovo (17) have gained the most attention.…”
