Optimización de la gestión de mantenimiento basado en la disponibilidad operacional de equipos en la planta de pintura de la empresa Ciauto Ambato-Ecuador.

Abstract

The objective of the present degree work was to optimize the maintenance management based on the operational availability of equipment in the paint plant of the company CIAUTO located in the parish of Unamuncho Camino Real - El Inca in the city of Ambato, Tungurahua province. When performing the previous evaluation to the teams; excessive failure modes were found that worsened the availability of this process, for which an information survey was carried out in each stage, identifying unavailability times, creating a fault history generated by line stoppages and unforeseen corrective maintenance of the series process of body paint; incorporating as part of the development of technical work, inventory control based on the STANDARD ISO 14224. With these results, the implementation of strategies and tasks that help to improve the management of the maintenance department is applied. The painting plant consists of seven stages, there being major critical inconveniences in the Elpo stage and the enamel furnace, whose equipment failures contribute to constant line stoppages. Optimizing this maintenance management consists in following up on the symptomatology of failures that will gradually mitigate the unavailability of the series stages that restrict the speed of the process and the loss of units produced per day, establishing an efficiency of 54.45 % in the production system, under certain conditions and operating times that will increase production. Applying this optimization of maintenance management, will improve the indicators of availability by accurately determining the current situation of equipment and processes, criticality analysis of equipment, calculations of availability by machinery and stages, establishing efficiency higher than 86.88% in the productive system.
