Diseño e implementación de una mejora de procesos para reducir el alto nivel de desperdicios, aplicando herramientas de Lean Manufacturing en una empresa ladrillera / Design and implementation of a process improvement to reduce the high level of waste, applying Lean Manufacturing tools in a brick company

Arévalo Barrera, Brenda Carolina, Parreño Marcos, Fátima Elena 22 January 2020 (has links)
El desempeño del PBI de Construcción ha sostenido un crecimiento significativo entre los años 2015 y 2017, llegando a superar el PBI Global con una proporción de 5 a 1. Dentro de este rubro, se encuentra el sector ladrillero que paralelamente incrementa su demanda debido a ser uno de los principales materiales utilizados en la construcción. La presente investigación engloba el estudio de pymes ladrillera que presentan una baja productividad, afectando su rentabilidad y participación en el mercado. El principal problema del proceso fue identificado utilizando como referencia estudios pasados y diagnósticos a todo el proceso productivo, a través de la aplicación de herramientas de ingeniería industrial (VSM, DAP, DR) en una empresa del sector. A partir de este análisis, se identifica que el problema es el alto nivel de desperdicios habiendo cuatro mudas presentes en el proceso: almacenamiento, tiempo de espera, reprocesos y productos terminados defectuosos. El modelo de solución de basa en el impacto a cada causa raíz identificado del problema, reforzándose en la filosofía Lean Manufacturing y empleando técnicas como 5S, SMED, TPM, Poka Yoke, Jidoka y estandarización del método de trabajo. Este modelo es validado a través de un piloto y una simulación presentando resultados comparables del proyecto propuesto. / The performance of the Construction GDP has sustained significant growth between 2015 and 2017, exceeding the Global GDP with a ratio of 5 to 1. Within this area, there is the brick sector that in parallel increases its demand due to being One of the main materials used in construction. This research encompasses the study of brick SMEs that have low productivity, affecting their profitability and market share. The main problem of the process was identified using as reference past studies and diagnoses to the entire production process, through the application of industrial engineering tools (VSM, DAP, DR) in a company in the sector. From this analysis, it is identified that the problem is the high level of waste, with four molts present in the process: storage, waiting time, reprocesses and defective finished products. The solution model is based on the impact on each identified root cause of the problem, being reinforced in the Lean Manufacturing philosophy and using techniques such as 5S, SMED, TPM, Poka Yoke, Jidoka and standardization of the working method. This model is validated through a pilot and a simulation presenting comparable results of the proposed project. / Trabajo de Suficiencia Profesional
