Sensitivity analysis of a hybrid-electric aircraft powertrain based on Sobol indices

An interpretation of the SIMP method based on topological sensitivity

We propose a random forest based estimation procedure for Quantile Oriented Sensitivity Analysis - QOSA.. In order to be efficient, a cross validation step on the leaf size of trees

This paper proposes a new sensitivity index, based upon the modification of the probability density function (pdf) of the random inputs, when the quantity of interest is a

On the contrary, based on available measurements of the track geometry and of the corresponding train dynamical responses, it can be shown that the method developed in Section II

Yet, we can use this method even when the inputs are dependent and Gaussian because we can separate the inputs into two variables : one corresponding to the variable of interest

Notably, we can observe that for the main-effect global sensitivity index for the first uncertain input variable, the estimate obtained with the PLoM method even for the small

By considering the ratio of each partial variance to the total variance, we obtain a measure of importance for each input variable that is called the Sobol index or sensitivity index

Evaluating this estimation uncertainty is crucial in practice as the limited sample size can lead to erroneous result from a certain level of perturbation (e.g. when there are
