  • Descrição: This paper presents a methodology, developed through a case study, to support preventive maintenance tasks selection based on Reliability Centered Maintenance (RCM) methodology. The case study was carried out in an electronic goods company that follows the Total Productive Maintenance (TPM) philosophy. The methodology has six steps and it is intended to be applied in every mechanical and electromechanically equipment of the plant and it is applicable in equipment with some historical data of interventions. To validate the methodology, one system of the plant was selected and all the steps of the methodology were followed. With this application, a reduction of 33% in failures number and production losses was achieved, as well as a MTBF improvement of about 15% and therefore an increase in machine yield. This chapter presents a methodology, developed through a case study, to support preventive maintenance tasks selection based on Reliability Centered Maintenance (RCM) methodology. The case study was carried out in an electronic goods company that follows the Total Productive Maintenance (TPM) philosophy. The chapter provides a short literature review. It focuses on the development of the critical equipment maintenance planning methodology and explains all its steps. Maintenance was based on the premise that every part has a defined life time at which it is necessary to do a general review, so it was applied the scheduled maintenance approach. RCM methodology is based on system functions, failure modes and effects study and its aim is to define the system maintenance requirements. The methodology has six steps: system selection and information collection; system barriers definition; system description and functional block diagram; system functions and functional failures; Failure Mode and Effects Analysis (FMEA); and decision tree analysis.
