Manutenção centrada em confiabilidade aplicada na redução de falhas: um estudo de caso

Abstract

The contemporary industrial systems are required to operate within limits, parameters and targets set, aimed at reducing costs and ensuring the availability and reliability. The Reliability Centered Maintenance (RCM) is techniques that can help organizations develop a systematic maintenance program to reach the goals effectively with a lower cost. The RCM combines other techniques and tools in a structured methodology for the selection of maintenance actions, reducing costs and unnecessary activities and increasing system reliability by reducing the occurrence of failures. The deployment model proposed in this work consists of steps: (i) system selection and data collection; (ii) identification of functions and functional failures of the system, (iii) Failure Mode Effects & Criticality Analysis (FMECA), (iv) selection of maintenance activities; (v) maintenance plan, and (vi) continuous improvement. This paper describes the methodology for implantation of MCC to reduce the functional failures of System Voltage Control of a lamination process, selecting critical components and identifying maintenance activities based on the operational context of each component and the consequences of their failures.
