In this paper, the author has considered an A.T.M. (automated Teller Machine) system to analysis its cost function. The author has been taken one parallel redundant bank computer to enhance system's overall performance. The whole system can fail due to either its normal working or human error. All the failures follow exponential time distribution where as all repairs follow general time distribution.
