Keywords: reliability indicators, distribution of Gnedenko-Weibull, mean residual life


The working life model (behavior model) of the object - the Gnedenko-Weibull distribution law is postulated. As a measure of reliability the article uses the mean residual time (MRL). For the Gnedenko-Weibull model, new representations of the mean residual are obtained. The considered example of processing real operational data of pumps failures allows predicting the residual operating time of submersible equipment at the operational stage and can be used to assess the resource characteristics of the equipment.
