.... This approach, in turn, enables the focused assessment of only those capabilities that are relevant to the challenge problem. The credibility assessment using PCMM is based on different decision attributes that encompass verification, validation, and uncertainty quantification (VVUQ) of the CASL codes. For each...

...%. Since both experiments and simulations involve models, it follows that tools developed for computer-simulation validation/uncertainty quantification (V/UQ) may be applied to experimental-data uncertainty analysis. Examples of these tools include the probability-bounds analysis of Ferson and Hajagos [ 17...
