A number of variance reduction Monte Carlo techniques have been proposed to overcome this difficulty; importance sampling methods are among the most efficient.

We describe two variance reduction methods for estimating the mean time to failure (MTTF) in Markovian models of highly reliable systems.

In this paper we describe several computational algo- rithms useful in studying importance sampling (IS) for Markov chains. Our algorithms compute opti-.

The mean time to failure (MTTF) of a Markovian system can be expressed as a ratio of two expectations. For highly reliable. Markovian systems, the resulting ...
