Diseño y aplicación de un modelo de gestión de inventario de repuestos e insumos para el mejoramiento de las actividades de mantenimiento de la flota automotriz del GAD Municipal de Guano

Abstract

The research addressed planning attention in automotive maintenance supplies at Gobierno Autónomo Descentralizado (GAD) of Guano. It focused on optimizing inventory management to improve automotive fleet maintenance activities. The methodology applied included an in-depth organizational diagnosis, highlighting aspects such as warehouse structure, inventory control systems, and incoming and outgoing records. An analysis of the demand for spare parts and consumables was carried out, guiding the design of an inventory management model based on the ABC system. The implementation of an economic ordering model sought to optimize supply and reduce inventory-related costs. The results revealed economic and mean time to repair (MTTR) improvements for the mechanical department, with a notable decrease in the steps required for the purchasing process. The application of the new model demonstrated tangible benefits, such as cost reduction, more efficient operation and accurate order planning. The analysis of automotive equipment failures and proposed solutions contributed to improving the reliability of the vehicle fleet. The solution was based on an economic ordering model implemented in Excel by adapting to the existing infrastructure. The final evaluation confirmed the success of the new model, highlighting the accuracy of inventory management, the prevention of delivery delays and the reduction of costs associated with stock-outs. The purchasing process was simplified, improving operational efficiency. In conclusion, the comprehensive research addressed inventory management in GAD of Guano, proposing effective solutions that generated significant improvements in operational efficiency and economic solutions in automotive maintenance activities.
