N2 - A parametric uncertainty analysis is described for a pulse load charging scenario for a simulation of a shipboard power system, assessing the propagation of the effect throughout the system. Models are developed to summarize the dependence of several response variables used to characterize the behavior of the simulated system in terms of six uncertain parameters of the simulation. Gaussian process models are constructed using adaptive sampling based on prediction variance, and sensitivity and uncertainty analyses are carried out on these surrogate models. Models are also constructed using a dimension-adaptive collocation method, and the results from the two approaches are compared.
