A STANDBY SYSTEM UNDER INTERFERENCE MODELS WITH ONE AND MORE REPAIR FACILITIES

Abstract

Here we have considered an n-standby system with one and more than one repair facility (ies) for interference (or stress–strength) models. The system is working under impacts of stresses. Each impact is called a cycle. When a component fails it goes for repair; the repair policy is first-come-first-serve (FCFS). The failure times of components, system and repair times all are measured in cycles. The reliability of the system at the Nth cycle is evaluated in different cases. When stress–strength distributions both are either exponential or gamma or normal the reliability of the system is numerically evaluated for given n, N and for some particular values of the parameters involved and are tabulated. The numerical values of the system reliability are on the expected line.
