... are expensive to obtain in complex engineering problems. This paper first proposes a new enhanced Mahalanobis distance (EMD) metric by multiplying the original Mahalanobis distance with a direction angle to incorporate the correlation information using limited experimental and simulation data. Combining...

... the scaling factor and the undetermined coefficients in GEMFS-RBF, an expanded correlation matrix is constructed by considering the correlations between the acquired samples, the correlations between the gradients, and the correlations between the samples and their corresponding gradients. To evaluate...

... correlation analysis (CCA)-based MFS model in which the least squares (LS) method is used to determine optimal parameters, named CCA-LS-MFS, is proposed. The CCA-LS-MFS model consists of three stages. The first stage is to construct two transition matrices of HF and LF samples using the CCA method...

... with the engineering systems with complicated correlations among various variables across levels by using the existing hierarchical sensitivity analysis method based on variance decomposition. To overcome this limitation, a mapping-based hierarchical sensitivity analysis method is proposed to obtain sensitivity...
