A 2-Dissimilar-Unit Redundant System With Repair And Preventive Maintenance

This paper presents the stochastic behaviour of a 2-dissimilar--unit cold-standby redundant system with repair and preventive maintenance. The Laplace-Stieltjes transform of (i) The first-passage time distribution to system failure, (ii) The expected number of system failures during (0, t], (iii) The probability that the system fails at time t, are all derived by using unique modifications of a Markov renewal process. Three examples are given.
