System characteristics of a two-unit repairable system are studied from a Bayesian viewpoint with different types of priors assumed for unknown parameters, in which the service station is unreliable. Time to failure and time to repair of the operating units are assumed to follow exponential distributions. In addition, the failure time and repair time of service station also follow exponential distributions. When time to failure and time to repair of operating units, failure time and repair time of service
station are with uncertain parameters, a Bayesian approach is adopted to evaluate system characteristics. Monte Carlo simulation is used to derive the posterior distribution for the mean time to system failure and the steady-state availability. Some numerical experiments are performed to illustrate the results derived in this paper.
