Abstract
This paper deals with the reliability and sensitivity analysis of a repairable system with M operating units S warm standby units and R unreliable service stations Failure times and service times of operating or standby units are assumed to be exponentially distributed While the service station is working it is subject to breakdowns according to a Poisson process When the station breaks down it requires repair at a repair facility where repair times follow the negative exponential distribution This paper provides the expressions for system reliability R Y t and the mean time to system failure MTTF We perform a sensitivity analysis for changes in the reliability characteristics along with changes in specific values of the system parameters Sensitivity analysis for the MTTF is also investigated
