This thesis studies the cold-standby M/M/R machine repair
problem with K failure modes under steady-state conditions. It
is assumed that any one mode of failure is served by one or
more repairmen, and the K failure modes have equal probability
of repair. Failure times of the machines and repair times of
the repairmen are assumed to be follow a negative exponential
distribution. A cost model is developed in order to determine
the optimal values of the number of cold standbys and the
number of repairmen simultaneously and maintain the system
availability at a certain level. Under the optimal operating
conditions, numerical results of sevsral system characteristics
are presented for three and four failure modes.
