Mechanical systems deteriorate over time and do not perform according to their intended functions and eventually fail due to the failure of one or more their components or units. Failed components are either repaired or replaced depending of several factors such as cost, criticality, or reliability. Repair is perfect, minimal, or imperfect. This study assesses the performance of a standby system which upon the failure of any component is either replaced or repaired. Two models are constructed and analyzed, the first model assumes the system to be perfectly repaired after each failure, whereas in the second the failed component is either replaced or imperfectly repaired. Steady state availably is used as a performance measure.
