Summary :

This paper considers a 2-dissimilar unit warm standby system. The failure rates are constant but the repair rates need not be constant. We shall say that a major breakdown occurs in the system when both unit fail. The system fails if one unit under repair is not repaired within a fixed time measured from the instant at which major breakdown occurs, or if the number of major breakdowns during the mission period exceeds a fixed number. As a special case, this number is allowed to be infinite". The Laplace transform of the reliability and the mean time to system failure (MTSF) are derived. The special case of constant failure and repair rates is treated. We present the asymptotic results which describe the performance of system with short mean repair time. Also the case when allowed down time is negligible, compared to the mission time, is discussed.
