Mejoramiento del proceso de ensamble en la línea chasis para automóviles modelo M4 en la Empresa Autopartista Ciauto CIA. LTDA. en la Ciudad de Ambato.

Abstract

The proposal for optimization of the M4 model car assembly process carried out at the company Ciauto Cia. Ltda, in Ambato in order to achieve reduction working times and maintain a control in the production with the desired quality in the final product. In order to optimize the production process, the information was collected by using method engineering techniques. Through these tools, the respective process analytical programs were obtained, getting assembly times in each of the substations under study, with an average production time of 39.53 minutes for each model car M4, substations E5-1, E5-3 and E5-5 have the highest times considered critical or bottlenecks that impede the continuous flow of the production process. The information obtained indicates that the planned takt time of 30 minutes is not accomplished, resulting in a daily production of 11 to 12 cars. The proposal for improvement was made by optimizing production processes, achieving eliminating delays, transports and unnecessary activities that produced losses in the company, in addition it was achieved to significantly reduce the total assembly time, resulting in a balanced production line more efficient. The proposal was simulated with the Promodel software, contrasting results; The indices of productivity indicate an improvement of 25% and a daily production of 15 cars, as well as increasing the percentage of utilization of the facilities from 80% to 93%. When applying the present study to achieve a balance in the whole assembly line of model M4 cars, similar times in the substations, which will allow the company to adapt easily to the increase in future demands.
