Abstract

The industrial performance of the company RUBAMINis based on the reliability of its critical equipment, notably the three-phase asynchronous motors. This study focuses on the diagnosis of repetitive failures of the "Slag" engine in order to optimize its availability. The methodology is based on a statistical analysis of the failure history using the Weibull probability distribution. This model allows to accurately determine the parameters of reliability R(t) , maintainability M(t) and availability A(t). By comparing theoretical results (failure rate and probability density) with operational reality, this project identifies performance gaps. The culmination of this work is the proposal for a revised maintenance strategy, moving from a reactive mode to a proactive approach adapted to real operating conditions.
