Desarrollo de un modelo de gestión para control del stock en inventario de repuestos de maquinaria automotriz utilizando herramientas Lean Manufacturing y Just in Time en un club privado de Quito

Abstract

In this research work, it was combined with quantitative research based on these methods, statistical and real data which were obtained on the current form of management of the QTGC maintenance warehouse. Currently there are many tools dedicated to optimizing processes within an organization, the Ishikawa diagram was considered an initial step to go from general to specific problems and, through that, add more tools related to problem solving. Applying the theory of Lean Manufacturing and collecting numerical data, it was possible to identify that exist some obsolete and slow-moving items that increase the inventory cost of the warehouse. With the use of data analysis software, projections were made for future problems detecting this type of items, the actual inventory reduction was 1.71 % and the projected inventory reduction was 5.79 %. The application of the 5 S', in contrast, helped to maintain correct order, safety when managing work, cleanliness and improve planning when replacing spare parts and purchasing new items. Additionally, more didactic methods were implemented that help detect materials without movement and that are about to expire. This method is based on the placement of colored cards (green, yellow and red), which indicate the state of the material.
