Mejora del plan mantenimiento, aplicando la metodología de la optimización del plan de mantenimiento, para el parque automotor de la Empresa Eléctrica Riobamba S.A.

Abstract

The objective of this technical work was to improve the maintenance plan by applying the maintenance plan optimization methodology for the automotive fleet at Empresa Eléctrica Riobamba S.A. The effective methodology was used because it rationalizes preventive maintenance (PM) and generates added value for maintenance management, the information from technical documents, failure histories, maintenance plans and operation manuals of the vehicle fleet was ordered through collection, analysis and classification of technical data inherent to operation and maintenance. Then the functional failures, consequences and operation were analyzed to formulate maintenance tasks for each group of equipment, the optimized preventive maintenance plan was also designed by grouping, prioritizing and dimensioning the new maintenance tasks, with the criticality functional analysis. to determine the critical systems where the consequences of failure are evaluated, designating the appropriate task for each failure mode in relation to its consequences. As a result, it was obtained from the new optimized plan made up of 56 tasks for its vehicle fleet, after having optimized the maintenance plan it can be seen that the new plan is structured by a total of 46 tasks, that is, this reduction of 17.86% is due because in the current plan there was the existence of repetitive tasks and ineffective tasks. In addition, it can be said that the evaluation of the current maintenance plan in the area reached a general average of 67%. Concluding that through the implementation of proposals or corrective actions, the efficiency and effectiveness of maintenance planning and programming can be increased. And it is recommended to apply the new maintenance plan to be able to correctly distribute the time, and that the maintenance tasks in the different vehicles do not accumulate.
