It is reasonable to expect that preparation time is needed to ready a repair facility before a repair can be carried out. A three-unit system with a "preparation time' for the repair facility is studied in this paper. The steady-state availability of such a system is obtained. The asymptotic confidence limits of the steady state availability are obtained numerically.
