Re-diseño, simulación y optimización de una línea de producción de asientos automotrices de la empresa Elasto S.A.

Abstract

This document has the purpose of making a detailed study for the improvement of the production line of front seats of the company Elasto SA, which is a company dedicated to the manufacture of automotive parts and pieces located in the city of Quito and whose Clients are both local and foreign assembly companies. The diagnosis revealed problems such as: some types of Lean Manufacturing waste, low productivity with respect to the current design, unsafe working conditions, production interruption, among others. The analysis revealed the need to elaborate flow diagrams, as well as perform the study of times, analysis of operations and a sequence of work for the operators. The work stations were defined together with the activities carried out in each one of them. A time study was carried out using a digital chronometer and its respective timesheet obtaining the average time in seconds, the normal time (assigning operator speed) and finally the standard time (establishing supplements). It balanced the workloads for each work station based on the Takt Time principle that relates the available time per day with the customer's demand and represents the rhythm that the production line must maintain. The Standardized Work must be an understandable recipe for any worker under the concept of continuous improvement and discipline; detailing the processes with images and symbology to work orderly in addition to looking for a continuous flow, improve delivery times, eliminate risks, among others. Each station on the line was equipped with the sequence sheet and its work element sheets.
