Propuesta de mejora del control de inventarios y la trazabilidad de materiales mediante el uso de códigos de barras, con metodología 5S en los procesos de producción de una empresa metalmecánica

Abstract

This technical project aims to improve inventory control and material traceability within the production processes of a metalworking company, where deficiencies have been identified in the identification, organization, registration, and tracking of the materials and inputs used in product manufacturing. An initial diagnostic revealed the presence of undocumented materials, inconsistent records, disorganized storage areas, the existence of “ghost materials” due to lack of identification, prolonged search times, and material deterioration caused by inadequate storage conditions. To optimize material management and reduce errors associated with handling and usage, the implementation of a barcode labeling system complemented by the 5S methodology is proposed. These tools enable more precise identification, real-time traceability, improved storage organization, and reduced material losses, thereby generating a more efficient workflow. The methodology applied in this project follows a quantitative-descriptive approach, supported by direct observation, operator interviews, and review of documentary records. The results obtained allow the design of a physical and digital labeling model adaptable to the company’s needs, as well as an organization and standardization plan based on the 5S methodology, aimed at ensuring timely material availability, improving workplace organization, and strengthening the efficiency of the production process.
