Abstract: Monte Carlo methods can be used to good advantage since the required probability of failure is formulated as a multi-dimensional integral of the probability density function of the basic variables over the system failure domain (which may not have a simple boundary). However, standard variance reduction techniques e.g. importance sampling or conditional Monte Carlo methods like directional simulation must be employed to obtain accurate estimates of the required probability with reasonable computational effort. The paper examines such importance sampling and directional simulation methods. Comparisons of accuracies and efficiencies are given. Finally, examples illustrating the procedure are presented, highlighting the advantages and disadvantages of each method.
