The aim of this work is to generalize reliability equivalence technique to apply it to a general series-parallel system consists of n subsystems connected in series, and each subsystem i has i m components connected in parallel system, with mixing life time and delayed time. We derive the reliability and mean time to failure of the original and improved(More)
The two-parameter linear failure rate distribution has been used quite successfully to analyze lifetime data. Recently, a new three-parameter distribution, known as the generalized linear failure rate distribution has been introduced by exponentiating the linear failure rate distribution. The generalized linear failure rate distribution is a very flexible(More)
In reliability analysis an investigator is often interested in the assessment of a specific risk in presence of other risk factors. It is well known as the competing risks problem in the statistical literature. In this paper we consider the analysis of incomplete data in presence of competing risks among several groups. We mainly consider the latent failure(More)
