Abstract

The objective of this curricular integration work consists in the preventive maintenance systematization of the vehicle fleet that belongs to EQUIPMENTS & SERVICES 3R CIA. LTDA. Company from Francisco de Orellana city, using the Maintenance focused on Reliability methodology. It began by evaluating maintenance management through the application of an instrument extracted from the degree work named "Development of an audit model for evaluating the maintenance management of physical assets based on international regulations applied to the study case: Unión Cementera Nacional (UCEM) Planta Chimborazo"; which allowed to know the company management level. In this analysis the maintenance planning item evaluation was found unsatisfactory, this issue justifies this project. A technical assets inventory was elaborated and then codified using the criteria of ISO 14224 standard, which helped to organize the information through technical sheets. Therefore, the assets criticality was analyzed with the CTR (Total Criticality by Risk) method. Subsequently, the RCM methodology was applied to determine the optimal maintenance activities in its current operational context and its technical and economic justification. The tasks frequencies were determined by several methods: the Weibull distribution application, the fleet maintenance personnel work experience and even maintenance manuals. From the development of this methodology, 1680 maintenance tasks with their respective frequencies were determined. Then, the matrix of the fleet preventive maintenance was structured, the necessary resources were assigned for each task: materials, spare parts, tools and labor for the 43 assets of the vehicle fleet. The preventive maintenance plan and the obtained information were registered and configured in the System maintenance. Finally, three maintenance technicians and one administrative technician were trained about systematization that was carried out.
