This paper treats the following decision problem to assign at the time of each failure the failed machine to a repair facility so as to minimize the long run average cost when K greater than or equal to 2. Using the theory of Markov processes the paper discusses this decision problem under various hypotheses 1 When failure and repair times have Erlang distribution 2 when the M mn machines are divided into G classes with a failed machine being replaced only by one of like class, each repair facility operates under a pre-emptive repeat priority queue discipline with class j having priority over class l greater than j, and failure and repair times have exponential distribution 3 when each machine is subject to delta different types of failure, the time to a failure of type i has exponential distribution, and repair times have Erlang distribution.
