Mejora de la productividad en la fabricación de las partes del techo aplicando el estudio de métodos y medición del trabajo en el área de fibrado de la Empresa Carrocería CAR – buss Yaulema del Cantón Riobamba

Abstract

Currently, the company "Carrocería Car-Bus Yaulema" is engaged in the manufacture of interprovincial buses. In the fiberglass area, they produce roof parts, where it was found that their production method is not standardized. This led to time-wasting tasks, causing delays in the delivery of fiberglass roof parts. Therefore, this study aimed to improve productivity in the manufacture of roof parts by applying methods of study and work measurement in the fiberglass area of Carrocería Car-Bus Yaulema in Riobamba canton. Using a mixed-method approach, the methodology began with data collection, including timing the activities of the production process. Flow diagrams, route diagrams, and process diagrams were also used to understand the activities at each workstation, aiming to standardize the production procedure by eliminating unnecessary movements and inactive times within the process. The time study technique was applied to identify factors causing downtime that limit work effectiveness. As a result, production time for the front, central, and rear parts decreased by 26.52%, 32.57%, and 30.26% respectively, increasing the production rate by 34%. This means each part was produced in 1 hour, 16 minutes, and 51.6 seconds; 5 hours, 4 minutes, and 0.6 seconds; and 1 hour, 56 minutes, and 37.8 seconds respectively. In conclusion, the company can achieve efficient production by incorporating equipment and techniques that significantly improve production capacity, as the proposed new method demonstrates an increase in production.
