In this study, the application of the RCM methodology (which is a maintenance management model) is shown in a factory of tongue and groove floors, in the area of Advanced Transformation; in this section is where the final finish of all floor surfaces is given. The application of the RCM methodology allowed the analysis of the primary and secondary functions, the identification of the failure modes, the effects of the failure and the hierarchy of risks of the most critical equipment of the system or problem area. The AMEF was carried out to determine the maintenance plan and in turn, with the NPR, the most critical failure modes were selected. Subsequently, these failure modes were analyzed in the information sheet and in the decision sheet with the objective of determining the activities and frequency of maintenance tasks. As a consequence of this analysis, documents were developed that help with the proper maintenance management (Resume, technical file, novelty report, maintenance service request, work order and maintenance report). Also, instructions for maintenance activities of the machines were developed. Finally, some results of the simulation of the methodology are shown, such as: the reduction of the average times to repair (TMPR) and the increase of the maintenance tasks concluded within the established term. These results will be reflected in the increased availability of plant equipment.
