Aplicação de indicadores de desempenho de manutenção em unidades geradoras de usinas termoelétricas, usando Motores ICO

Abstract

This paper develops a conceptual approach regarding equipment maintenance, as well as its management through the implementation of performance indicators in a Thermoelectric Power Plant. The maintenance management has been, year after year, adapting to new methods, focusing mainly on decreasing productivity losses and reducing costs. Improving processes makes it possible to anticipate failures and breakdowns of equipment, reducing pauses in production and poor operating time, consequently improving product quality. For this analysis, some of the data monitored by the information system of the company were used, which are: production time, number of failures that caused interventions and machine repair time. The data were applied to calculate MTBF (Mean Time Between Failures), MTTR (Mean Time to Repair), Availability and Reliability. It was verified that monitoring of equipment performance indicators allows better conditions for decision making, providing managers vital information for effective process control. In addition, it provides a feedback of the results obtained with corrective, preventive and predictive maintenance. It is notable that if greater emphasis is placed on analyzing machine failures, an increase in availability can be achieved. The results obtained in this study indicate which equipment presented higher and lower indices according to the predicted goal.
