Reliability Modeling of a System With One Main Unit and Two Associate Units Along With Sub-Unit

In this paper, we develop a stochastic reliability model of one-unit main system with two associate units. Each unit also has one sub-unit. Sub-units depend upon Associate units and the unit. The will be operable when at least sub-unit are in operation. As soon as job arrives, all work load. It is assumed that only taken for processing time. There single repairman who repairs failed on first-come-first-served basis. Various characteristics effectiveness obtained by using semi-Markov processes regenerative point techniques.
