Item Modelo lean manufacturing para la eliminación de desperdicios en la empresa Curtiembre Aldas(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería Industrial, 2025-02) Peñafiel Ibarra Juan Carlos; Ortiz Guerrero Daysi MargaritaThis project presents a proposal for implementing Lean Manufacturing methodology at Curtiembre Aldas, located in the Tungurahua province of Ecuador. The company specializes in transforming cattle hides into finished leather for footwear and clothing. The main focus of this proposal is to eliminate non-value-adding activities, targeting key wastes such as unnecessary movements, excessive transport, and waiting times. Through the use of Lean tools, these issues within the company were addressed effectively. The research suggests the application of the 5S methodology to improve workstations by introducing manuals and systems for order and cleanliness. This approach aims to minimize time lost searching for tools or cleaning equipment, resulting in a significant 35.6% improvement compared to the company’s initial performance. As part of the SMED methodology implementation proposal, internal activities were converted into external ones, effectively organizing the necessary tools and equipment at the workstations. This led to reduced machine changeover times: from 25.83 minutes to 15.11 minutes on the splitting machine, from 68.44 minutes to 46.54 minutes on the trimming machine, and from 31.42 minutes to 19.06 minutes on the fleshing machine. Following the implementation of both methodologies, noticeable improvements were achieved in the production processes of Curtiembre Aldas, particularly in the ribera area.
