Optimización del proceso en la línea de ensamblaje de estructura de carrocerías para buses en chasis tipo AK en la empresa carrocerías Modelo en la ciudad de Santo Domingo de los Tsáchilas.

Abstract

The aim of this technical project was the process optimization for the structural assembly line of buses with AK-type chassis for Carrocerías Modelo in Santo Domingo de los Tsáchilas canton, with the objective of obtaining better processes in the assembly areas, fundamental stage of the body construction. An investigation on methods to reduce times and movements in carried out activities was conducted, thus optimizing resources to increase productivity of the enterprise. A current situation analysis of the enterprise was performed aiming to implement suitable methods and standard times applicable to production, innovating and maintaining quality, without increasing production costs. The main problem to solve through this research work was the delay on the assembly process, principal motive of customer dissatisfaction due to failing in meeting job deadlines. Consequently, a method adjusted with the need of the enterprise was needed to assist the enterprise improving productivity. To support this research, experts in the bus body construction were consulted, who affirmed that industrial engineering along with an optimization method allows to reduce stages and manufacturing times without reducing assembly quality, continuous improving method (Kaizen). In conclusion, in the assembly area, a reduction of 93.48% of activities and a 49.55% of times was achieved, obtaining a production of two structures per day´s work applying the proposed method, recommending readjust, reorder and distribute the working areas to improve performance and efficiency of the employees.
