An example of application of software for assessment reliability distribution

Abstract

The paper presents a algorithm for estimation and selection of optimal reliability distribution. Reliability estimation is performed by means of the author’s own software solution which is based on the selection of one of the six most frequently used theoretical distribution functions (exponential, Weibull, normal, lognormal, Rayleigh and gamma). An example of failure of bearings in centrifugal pumps of water supply pumping stations is analyzed. The software solution enables simple data input, necessary calculations and graphical representation of reliability indicators, as well as the nonparametric estimation of statistical hypotheses.
