The Productivity of Rotating Machines under the Case of a Server with a Spare Machine

This paper proposes a practical approximation method for productivity evaluation of N rotating machine system which are served by single with spares. The productivity of the system is measured by the efficiency of the machines and by the utilization of the single server. In example cases, the results from the interative approximation method showed very little differences from simulation results. Furthemore, the proposed method has some advantage in computation time and cast over the simulation.
