Aplicação de métodos da manutenção centrada em confiabilidade para determinação do ponto ótimo de manutenção preventiva em um equipamento de uma indústria frigorífica de médio porte do sudeste de Minas Gerais

Abstract

The Reliability Centered Maintenance (RCM) activities are recognized as an effective way to conduct maintenance activities. It enables the company to achieve its operational excellence, making it more competitive since the reflexes of a well- applied RCM directly impact the operational costs of the production line, reducing costs associated with defects, repairs, replacements, accidents in addition to providing greater availability indexes of plant assets. This paper discusses the results of the application of concepts and tools of maintenance centered on reliability in a critical equipment of a sector with high demand for maintenance in a medium-sized beef and pork slaughterhouse in southeastern Minas Gerais. For this purpose, equipment shutdown data were collected, which made it possible, using the Weibull probability distribution method, to determine the cumulative distribution of failures, reliability and availability of the equipment in relation to its operating time. In addition, the costs of preventive and corrective maintenance of the equipment were determined, which made it possible to determine the optimum operating time of the equipment for a preventive intervention by the maintenance team.
