Sistema integrado de manutenção centrada na confiabilidade (MCC) auxiliado por lógica fuzzy

Abstract

The Reliability-centered Maintenance (RCM) has become increasingly important within industries, where tiny improvements projects huge profits. Specifically, the FMEA/FMECA tool, largely applied in RMC concept, has fundamental protagonism in actions priorization within a efficient maintenance plan. However, the FMEA/FMECA has some limitations, from your mathematical mecanism. The proposal is to reduce significantly the limitations of the FMEA/FMECA tool acting on the priorization methodology of the failures modes. For this, the fuzzy logic was used to modify the application of the tool. With success, a Java application was proposed and developed, which brings together the versatility of the FMEA/FMECA tool and a more elaborated calculus algorithm to obtain the risk priorization number (RPN) of the original FMEA/FMECA. The results are satisfactory and the main tool limitation was overcome. In this way, a more efficient priorization of the failures modes could be done.
