2. The purpose of the probabilistic modeling is to simulate the effects of variability in the system, its environment, and the uncertainties in the performance prediction methods on the performance. The numerical simulation combines deterministic analytical or computational methods in a probabilistic structure in which the variabilities and/or uncertainties are treated quantitatively.
