Abstract
La presente investigación se realizó en una empresa, dedicada a la confección
textil, teniendo como principal objetivo aplicar herramientas de Lean
Manufacturing y demostrar la mejora en los indicadores de calidad de la línea
de polos, para tal fin se hizo uso de una metodología aplicada de tipo
preexperimental, dónde primero se realizó el análisis y diagnóstico de la
empresa para identificar los principales problemas que afectan a los
indicadores de gestión de calidad. A partir de las problemáticas encontradas
como fallas de equipo, excesiva merma y productos defectuosos y finalmente
desorden y movimientos innecesarios, se procede a plantear propuestas de
mejora mediante el uso de herramientas lean manufacturing como 5S y TPM,
además de herramientas de seguimiento (auditorias de 5S) que garanticen que
los cambios realizados se mantengan en el tiempo.
Dentro de los resultados obtenidos con la implementación propuesta se logró
reducir el tiempo estándar del proceso de elaboración de polos en 13.2
minutos, asimismo, el OEE aumentó en 24.56%. Con estos datos se logró
reducir el ratio de reclamos en 5.0%, aumentar el % lote perfecto en 6.7%, el
cumplimiento de entrega en 9.6%, la efectividad en 6.3%, la satisfacción de
clientes en un 21% para finalmente obtener un NPS final de 60%. Luego se
realizó la evaluación económica, dónde se obtuvo un VAN de S/23,223.64, una
TIR de 24.1% y la relación costo beneficio de 3.6, lo que indica que el proyecto
es rentable y puede ser implementado.
The present research was carried out in a company dedicated to textile manufacturing, with the main objective of applying Lean Manufacturing tools and demonstrating the improvement in the quality indicators of the shirt line. For this purpose, an applied methodology of pre-experimental type, where the analysis and diagnosis of the company was first carried out to identify the main problems that affect the quality management indicators. Based on the problems found such as equipment failures, excessive waste and defective products and finally disorder and unnecessary movements, proposals for improvement are made through the use of lean manufacturing tools such as 5S and TPM, in addition to monitoring tools (5S’s audits) that guarantee that the changes made are maintained over time. Among the results obtained with the proposed implementation, it was possible to reduce the standard time of the popsicle making process by 13.2 minutes, likewise, the OEE increased by 24.56%. With this data, it was possible to reduce the complaints ratio by 5.0%, increase the % perfect batch by 6.7%, delivery compliance by 9.6%, effectiveness by 6.3%, customer satisfaction by 21% to finally obtain an NPS final 60%. Then the economic evaluation was carried out, where a NPV of S/23,223.64, an IRR of 24.1% and a cost-benefit ratio of 3.6 were obtained, which indicates that the project is profitable and can be implemented.
