Profit Evaluation of an Identical Units System with Arbitrary Distribution

In this paper we do profit evaluation of parallel system of two identical units with arbitrary distributions. Every one unit has absolute failure from standard mode. The structure is measured in up-state if as a minimum of one component is functioning. Failed unit (in case of failure) is mended by server who visits the system without delay for doing repair of the unit. After giving fixed repair time to server it is replaced by new one giving some replacement time. Profit evaluation of the system is done by using arbitrary distributions to all random variables by using Semi-Markov process and RPT. The numerical study of the results obtained for a particular case has also been made.
