| Summary: | The article deals with the survival analysis of a.c. machines operating under the conditions of the underground mine “Mir” (Yakutia). The estimation of their survival is carried out using the Kaplan-Meier estimator. The main advantage of this method is in the opportunity to process censored (incomplete) data, which in turn leads to the accuracy of results. The statistical data used in this article were obtained from maintenance books and reports made by a repair team working in the considered mine. This analysis allows not only identifying faulty electric machines and their fault-free operation but also the faulty components of a certain electric motor. |
