In this paper, we examined the reliability of Funtone software and its impact on quality service to the user. As Global System for Mobile (GSM) software is relatively new in the market and the level of awareness of its quality service is low; the need for quality assessment of these services...

Purpose – The purpose of this paper is to compute reliability, availability, and mean time before failure of the process of a plastic‐pipe manufacturing plant consisting of a ( K, N ) system for various choices of failure and repair rates of sub‐systems. This plant consists of eight...

Purpose – To present the bootstrap procedure to correct biases in maximum likelihood estimator of mean time to failure (MTTF) and percentiles in a Weibull regression model. Design/methodology/approach – A reliability model is described by a Weibull regression model with parameters being...

In this paper one considers a model representing a two‐unit identical system with one unit operating online, and the other unit in warm standby. The online unit is controlled by a protective unit which protects the online unit from any damage occurring. The online and protective units may fail...
