In this paper, we consider a repairable system in which two types of failures can occur on each failure. One is a minor failure that can be corrected with minimal repair, whereas the other type is a catastrophic failure that destroys the system. The total number of failures until the catastrophic failure is a positive random variable with a given probability vector. It is assumed that there is some partial information about the failure status of the system, and then various properties of the conditional probability of the system failure are studied. Mixture representations of the reliability function for the system in terms of the reliability function of the residual lifetimes of record values are obtained. Some stochastic properties of the conditional probabilities and the residual lifetimes of two systems are finally discussed.failures by minimal repairs, and by system lifetime, we mean the time until a catastrophic failure in the system. The aging properties of the system, under the condition that the system can be repaired (N − 1) times and the Nth failure destroys the system, has been studied in [16]. In this paper, we consider the situation when one may have some partial information about the system lifetime, i.e., the time until the catastrophic failure, and we are then interested in finding the dynamic
