Elaboración de un plan de mantenimiento mediante la metodología del mantenimiento centrado en la confiabilidad para el grupo 2 de vehículos del Gobierno Autónomo Descentralizado Municipal de Riobamba

Abstract

The purpose of this technical project was the development of a maintenance plan based on the Reliability Centered Maintenance (RCM) methodology for group 2 of vehicles of the Municipal Decentralized autonomous Government of Riobamba (GADMR). As a first point, the evaluation of the current maintenance management was performed through the technique called “Maintenance Effectiveness Survey” (MES), also the inventory of the equipment was made, in addition the criticality analysis was carried out through a semi-quantitative tool called Risk Criticality Matrix (MCR), this allowed to identify the highly critical equipment to which the methodology of Reliability Centered Maintenance (RCM) was applied, Two important documents emerged, the first one called “Information Sheet” and the second one called "Decision Sheet” where the functions, functional failures, failure modes, effects and consequences were established in order to determine maintenance tasks with their respective frequency and the necessary resources to execute them, as well as training for the administrative and technical staff of the Municipal Workshops. The evaluation revealed opportunities for improvement in all areas, but with greater emphasis in the area of information management. The critical analysis included the identification of 5 highly critical pieces of equipment, and the RCM methodology yielded a bank of 880 maintenance tasks with their respective frequency and logistics. In conclusion, it was determined that the maintenance plan will allow improving maintenance management, having better control over the assets and the tasks delegated to them, in order to avoid the greatest possible number of stoppages. It is recommended to establish a maintenance management evaluation committee, to maintain the codification line, and to have a training program on the applied methodology.
