Mejoramiento de la capacidad productiva aplicando herramientas de manufactura esbelta en la construcción de calderas generadoras de vapor

Abstract

SUMMARY The present research work proposes to improve the productive capacity through the application of lean manufacturing tools in the construction of steam generating boilers, specifically in the company “Gilberto Narváez Mecánica y Electricidad Industrial”. As a starting point for the research, the methodology proposed by the “Organización Internacional de Trabajo”, which begins through the introduction to the organization and selection of the product for study, in this first point we delved into the important aspects of the company and it was established after analysis that the boiler to be studied would be the so called GN.1001–LTJ; to later, and following the OIT methodology, record the process by observation in the field, resorting to appropriate techniques such as course charts, then the standard time of each activity and cycle time of the construction process of the boiler under study was calculated, thus making it possible to make visible clearly those activities that control the production process and that would become the points for improvement. Subsequently and in accordance with the provisions of the OIT, the methodology proposed by the “Escuela Española de Organización Industrial” was accepted, which recommends continuing the investigation with the diagnosis and training of the starting situation where it was identified on the points susceptible to improvement of waste and the lean manufacturing tools that best match their elimination were established, in order to assert that the implemented system provides benefits to the organization, the current situation was measured through indicators, the next phase of this methodology is the launch of the system, that is, the radical changes in the construction process are presented, and it is after this that the process is measured again in order to compare the current situation with the improved one and corroborate improving productivity.
