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 Provincial de Chimborazo

Abstract

This technical project objective is to develop a maintenance plan using the Reliability Maintenance methodology for group 2 vehicles of the Provincial Decentralized Autonomous Government of Chimborazo. For this, the latest maintenance management was analyzed through an audit of the Maintenance Effectiveness Survey (EEM). It demonstrated that it is in the Acceptable category, identifying that the planning area has an opportunity for improvement after obtaining the lowest score. The improvement proposal covers the development of the Maintenance Plan based on updating the technical inventory information, coding the vehicle fleet according to the ISO 14224 Standard, and identifying the principal vehicle systems. Subsequently, the criticality analysis was performed, using the semiquantitative risk criticality matrix “MCR” methodology to determine the level of each equipment so we could prioritize maintenance strategies for the most critical equipment. The “RCM” methodology was carried out to define the new maintenance tasks and the annual maintenance schedule, taking into account the information sheet that mentions seven function systems with their functional failures, failure modes, the effects, causes, and consequences when the failure occurs. To prevent failures 592 condition-based tasks and 540 cyclic reconditioning tasks were established. Finally, the personnel in charge of the management and execution of maintenance were trained to publicize the project carried out, as well as give viable recommendations for carrying out maintenance, highlighting the feasibility of implementing software to manage maintenance correctly, thus achieving good maintenance practices that exceed 70% in the evaluation of maintenance management.
