Propuesta de optimización del sistema de control de inventarios en el área de mantenimiento de los ítems para los equipos utilizados en la industria de consumo masivo

Abstract

The research focuses on optimizing the inventory control system in a mass consumption industry within the food sector, specifically in the spare parts maintenance area. The study highlights the importance of mass consumption industries, not only because of their economic impact but also for their ability to meet changing demands. Despite the use of ERP systems like SAP and Oracle, the research identifies that without proper data management, these systems lose effectiveness, leading to issues such as overstocking or the lack of items in inventories. The main objective of the research was to optimize inventory control, specifically for items with critical turnover. To achieve this, an ABC classification model based on the criticality of the machines was proposed. The analysis of 671 items and 3,134 inventory movements since 2019 showed that optimizing control could reduce 70.9% of the items, revealing an excess of inventory that results in unnecessary overstocking. The conclusions suggest that the ABC classification and the reorganization of the warehouse, prioritizing high-turnover spare parts, would significantly improve efficiency, optimizing available space and reducing search times. Additionally, it was observed that 80% of the inventory cost is found in low-turnover items, but those critical to the functioning of the machines, highlighting the importance of proper inventory management to avoid production failures.
