Simulation methods have recently been developed for the solution of the extremely large Markovian dependability models which result from complex fault-tolerant computer systems. This paper presents efficient simulation methods for the estimation of transient reliability/availability metrics for repairable fault-tolerant computer systems which combine estimator decomposition techniques with an efficient importance sampling technique recently developed. Comparison with simulation methods previously proposed for the same type of metrics and models shows that the methods proposed here are orders of magnitude faster.
