摘要：

A tool based on the Markov model is described, using fuzzy theory, for the reliability and safety evaluation of fault-tolerant computational systems. As the Markov model requires some parameters which may not be well known during the calculation, this method allows uncertainty-based parameters represented as fuzzy numbers. As a consequence, the reliability/safety time response is also fuzzy and each resulting curve has an associated degree of confidence.
