Análisis y estandarización de procesos en el área de talleres empleando herramientas Lean Manufacturing en la Empresa SIPROELECTRIK S.A. ubicada en Quito

Abstract

The main objective of this technical research was the standardization of processes in the workshop area by Lean Manufacturing tools in the company SIPROELECTRIK S.A., located in Quito city. First, through the Pareto diagram, the mechanical and electrical maintenance processes were selected as the ones to be standardized. Then, VSM (Value Stream Map) diagnostic tool was applied, which yielded a time of 12 hours, 53 minutes, and 19 seconds. Additionally, the initial 5S' were evaluated, showing 36.33% compliance for the control area, 47.43% for the mechanical area, 32.67% for the machining area, 36.57% for the winding area and 31.67% for the painting area, with an average compliance of 37.73%; the OEE index was also calculated, which gave a value of 42.78%, reflecting an unacceptable level. After the initial diagnosis, Lean Manufacturing tools were implemented, beginning with the application of the 5S methodology, which allowed the organization, normalization and standardization of procedures in the workshop area of the company, as well as the development of TPM (Total Productive Maintenance) based on the pillars: focused improvement, autonomous maintenance, planned maintenance, training and safety, which allowed raising the OEE index to 64.17%. The implementation of Lean Manufacturing tool reduced the cycle time by 25 minutes and 25 seconds and reached an average value of 83.92% for the 5'S compliance level, which is a highly satisfactory result. Periodic checks are recommended to ensure continuous improvement based on the proposed techniques and methods.
