Reliability and Availability Analysis of Arepairable System With Two Types of Failure

Abstract

This paper investigates reliability and availability of a repairable system with two types of failure. Let failure rate and repair rate of [type1, type2] components are assumed to be exponentially distributed. The expressions of availability and reliability characteristics such as the system reliability and the mean time to failure are derived. We used several cases to analyze graphically the effect of various system parameters on the reliability system and availability system.

Reliability Performance of Improved General Series-Parallel Systems in the Generalized Exponential Lifetime Model

“…Beyond the assumptions of constant hazard rates, equivalent studies have been concerned with other lifetime distributions. The gamma distribution was addressed in [18], the Weibull distribution was modeled for a series parallel system in [17], the exponentiated exponential distribution was proposed for the parallel system in [19], reliability equivalence factors of a system with a mixture of independent and non-identical components with delay time were obtained in [20], the exponentiated Weibull distribution was considered for a series parallel system in [21], two types of failure rates in a series-parallel systems were analyzed in [22], the reliability equivalence factors of a general parallel system with a mixture of lifetimes were explored in [23], and improving the reliability of a series-parallel system using the modified Weibull distribution was applied in [24].…”
