Abstract : Two types of maintenance systems are examined: (1) a multicrew system with 'preemptive priority' discipline; (2) a multi-service Markovian system with 'first come first served' discipline. In the first model, four operating characteristics are obtained for machines of priority type p: average number of machines in the system and in the line, and the corresponding waiting times. In the second model the policy structure is analyzed. A procedure is attained for choosing the optimal policy for controlling such a system. It is shown that optimal policies are of the connected type and that only in one case any one of the finite number of policies will yield the same value for the objective function.
