Mejorias en la Productividad de un Proceso de Prefabricados de Concreto con Flujo en Linea Despues de un Esfuerzo de Estabilidad Basica

Publication: Journal of Construction Engineering and Management
Volume 140, Issue 4

Abstract

Los principios y metodología lean han sido aplicadas con éxito en plantas de prefabricados y flujo de lotes. La transformación de procesos en ambientes de flujo de lotes a flujo en línea es la principal causa de beneficios en productividad reportadas en la literatura. Por medio de una investigación-acción enraizada en la filosofía lean, mostramos que beneficios en la productividad son posibles en procesos de prefabricados que ya se encuentran funcionando con flujo en línea. El presente estudio fue realizado en una compañía donde previamente se habían medidas de la filosofía lean, tales como MCV (Mapa de Cadena de Valor), organización del área de trabajo(5S), sistema empujado y MPT (Mantenimiento Productivo Total). Dicha iniciativa trajo como consecuencia mejoras en la productividad, a pesar que de una manera variable y no constante. El enfoque de esta investigación pudo idear una estabilidad simple en el proceso teniendo como foco la metodología y mano de obra. Después de una serie de ciclos de mejoría, el proceso de producción consiguió una estabilidad casi completa y obtuvo adicionalmente una mejora de la productividad del 24%. Estos resultados sugieren que al descuidar el tema de la estabilidad durante procesos de implementación lean dichos esfuerzos se traducen en pérdida parcial del potencial de mejorías, sin mencionar el riesgo de perder todas las mejorías ya obtenidas, inclusive en ambientes aparentemente optimizados tales como líneas de flujo.
