We consider the dynamic repair allocation problem for a general multi-component system that is maintained by a limited number of repairmen. Component functioning and repair times are assumed to be exponentially distributed with parameters that may depend on the component but not on repairmen. At most one repairman may be assigned to a failed component. The objective is to determine repair allocation policies that maximize a measure of performance for the system such as the expected discounted system operation time or the availability of the system. We consider systems composed of highly reliable i.e., small failure rates, components and study asymptotic techniques for the determination of optimal policies. In the final section we find asymptotically optimal policies for the series, parallel and a system composed of parallel subsystems connected in series. Author
