Estudio de caso acerca de la estandarización de los procesos de reparación de sistemas de inyección diésel electrónicos en un Laboratorio Diésel, utilizando la metodología Lean Manufacturing y Lean Six Sigma

Abstract

This degree project presents the development of a case study aimed at improving the repair process of electronic diesel injectors at Laboratorio Diesel Solution, located in Villavicencio. The project arises from the need to optimize operational efficiency and reduce repair times, rework, and associated costs through the application of Lean Manufacturing tools and the DMAIC methodology from Six Sigma. Initially, a situational diagnosis was carried out to identify bottlenecks, deficiencies in the workspace layout, and the lack of standardization in critical activities. The measurement phase made it possible to establish key indicators such as OEE, sigma level, average repair time, and warranty rate. Subsequently, through the Ishikawa analysis, improvement strategies were implemented based on the 5S methodology, time and motion studies, and the creation of a Kanban board for visual process control. As a result, there was a significant reduction in repair times, an improvement in the organization of the technical area, and an increase in the reliability of the serviced equipment. Finally, control indicators were established to ensure the sustainability of the implemented improvements and to support future decision-making within the laboratory.
