Con el propósito de neutralizar los diversos problemas de pérdidas productivas, en los procesos constructivos se desea implementar la herramienta Value Stream Mapping (VSM) la cual pertenece a la filosofía Lean Manufacturing que es implementada en Lean Construction, con el fin de tener una construcción sin pérdida, dicha herramienta consiste en la creación de mapas que representan el procedimiento de las actividades y flujos de información necesarios para obtener un producto en su etapa final, en este caso sería la obtención de un elemento estructural. La cual nos podrá ayudar a obtener un diagnóstico del estado actual de los procesos. Value Stream Mapping no solo detecta los problemas productivos desde su origen, si no te ayuda a poder proponer mejoras en los procesos con el objetivo de poder eliminar las pérdidas productivas del proyecto en general. Una vez analizada las propuestas de mejora se procederá a realizar un mapa de estado futuro obteniendo un mayor rendimiento en el ciclo de producción. Los datos obtenidos en campo fueron tomados en un periodo aproximado de 3 meses en la obra “Condominio Bolivia Nº 4848” (Edificio Multifamiliar) dichos datos permitieron obtener el rendimiento productivo actual de los procesos, mediante la herramienta Value Stream Mapping se procedió analizar el estado actual y elaborar el mapas de flujos de valores para ver el estado futuro del proceso del elemento estructural. Para la elaboración del mapa del flujo de valor futuro se consideró las mejoras obtenidas por el Value Stream Mapping, finalmente, se justifica que si se puede mejorar los procesos constructivos a través de la herramienta Value Stream Mapping. / In order to neutralize the various problems of productive losses, in the construction processes we want to implement the Value Stream Mapping (VSM) tool which belongs to the Lean Manufacturing philosophy that is implemented in Lean Construction, in order to have a lossless construction, this tool consists in the creation of maps that represent the procedure of the activities and information flows necessary to obtain a product in its final stage, in this case it would be to obtain a structural element. Which can help us get a diagnosis of the current state of the processes. Value Stream Mapping not only detects productive problems from its origin, it does not help you to be able to propose improvements in processes in order to eliminate the productive losses of the project in general. Once the improvement proposals have been analyzed, we will proceed to make a future status map obtaining a higher performance in the production cycle. The data obtained in the field were taken in a period of approximately 3 months in the work "Bolivia Condominium No. 4848" (Multifamily Building) this data allowed to obtain the current productive performance of the processes, using the tool Value Stream Mapping proceeded to analyze the current state and develop the value flow maps to see the future state of the structural element process. For the development of the future value stream map, the improvements obtained by the Value Stream Mapping were considered, finally, it is justified that if construction processes can be improved through the Value Stream Mapping tool. / Tesis

En este trabajo se analiza el modelo de producción de una planta de extracción y procesamiento de materiales para la construcción del radio urbano de la ciudad de Lima, buscando identificar aquellos factores que afectan a su productividad. Mediante un análisis basado en el mapeo del flujo de valor de los procesos (value stream mapping) tomando en consideración tiempos, secuencia y flujos, se identificaron las restricciones del sistema, sus cuellos de botella y los trabajos no “contributorios”. Utilizando esa información, se individualizaron los procesos constitutivos y se identificaron sus problemas. Aplicando los métodos de la filosofía Lean, se evaluó que es posible modificar los factores de éxito como alcance, tiempo, costo y calidad. Esto permitiría lograr a corto plazo una mejora en la productividad de la empresa. Además, la incorporación de premisas guías de gestión de la calidad y gestión del mantenimiento pueden resultar en otras oportunidades de mejora. La propuesta desarrollada proporcionaría los siguientes beneficios para la empresa: identificación de las principales causas de las paralizaciones en la producción, mejora del registro, control y evaluación de los procesos, incremento en la vida útil de los equipos y maquinaria, y reducción de los tiempos en los procesos operativos. Una conclusión importante es que será el monitoreo periódico el que permitirá que la mejora en la productividad sea una constante en la empresa. / This work is devoted to the analysis of the production model of a construction materials extraction and processing plant of Lima City, identifying those factors that affect its productivity. By applying a value stream mapping analysis considering operation times, sequencies and streams, the main system restrictions were identified along with bottlenecks and non-contributing activities. This information allowed to identify each individual process and associated problems. By applying the Lean Method, it would be possible to modify the success factors such as reach, times, costs and quality, which would allow to improve the plant productivity in the short term. In addition, the inclusion of guidelines of quality control management and maintenance control management could represent novel opportunities for quality improvement. The proposal developed here would result in the following benefits for the company: identification of the main causes of stoppages in production, improvement of the record keeping, control and evaluation of processes, enhanced lifetime of equipment and machinery, and reduction in operational times. An important conclusion is that only by periodically monitoring the system a long-lasting company productivity improvement could be achieved. / Trabajo de investigación

Purpose – The purpose of this study is to increase the knowledge about the material handling of a module house manufacturing company. In order to achieve the study's purpose, three research questions were formulated. ▪ Which factors affect material handling? ▪ Which factors are considered important for material handling? ▪ How can standardization improve material handling? Method – The study has been characterized by an inductive approach to conducting the case study. To achieve the purpose, empirical data has been collected via a pilot study, interviews, observations, and document studies from reality. Subsequently, previous theories were examined via a literature collection. Furthermore, the processing and analysis of collected empirics and theory have helped to answer the purpose and demonstrate the generalizability of the study. Findings – The study has focused on the entirety of the various processes and an understanding of the various factors that influence material handling has been obtained. The case study company has challenges to look at the entirety of the modular house production and separates the production and construction sites. The wastes transport, movement, waiting and unused skills are considered to be the most important wastes to reduce or eliminate. It is clear that the case study company’s new employees must constantly reinvent the wheel and learn from their own mistakes. Moreover, it is difficult to determine if the mistake is a deviation, error or insufficient knowledge. By implementing a standard for what should be on drawings and how materials are to be delivered from production to the construction sites, deviations and wastes can be reduced and costs reduced. Implications – The study is based on a problem area that already exists in separate theories and comparisons. However, operations that have a material handling that both concerns manufacturing and construction work have not previously been investigated to the same extent, which is the theoretical contribution of the study. The empirical contribution to the study is to identify which factors affect material handling in businesses that have common flows between manufacturing and construction work. Limitations – The study only addresses two of the material handling flows; the material flow and the information flow. The study also does not take into account the processes of suppliers, subcontractors, or customers. Finally, the study will not include financial calculations to demonstrate potential cost efficiencies. Keywords – Material handling, Lean, Construction logistics, Wastes, Current flow, Value stream mapping, Lean tools.
