BIAF code for reliability studies.

The systems we want to evaluate the reliability are more and more complex. Analytical developments related to classical models are no more sufficient. The Monte Carlo method provide a mean to compute important statistique to evaluate reliability which the analytical models are unable to predict. The BIAF code is a simulation program based on a state description of the system. This code is able to study non markovian system like delays. It can evaluate first passage probability, sojourn time, path probability... and is able to follow in time special physical conditions (temperature variation for instance). Several biasing techniques are used in BIAF. We try to optimise the variance of some estimators. [ABSTRACT FROM AUTHOR]
