Abstract

A common problem in Probabilistic Risk Analysis (PRA) is to find the distribution of a function of random variables, i.e.,
$$\text{Y = f}\left( {\text{X}_\text{1} \text{,}\,\text{X}_\text{2} \text{, \ldots \ldots ,X}_\text{n} } \right)$$
(1)
Y may be the failure rate of a system or the rate of occurrence of an event, while Xi may be the failure or repair rate of a component, a human error rate, etc. The probabilistic model, e.g., a fault tree, determines the function f.
