Propuesta de balanceo de línea mediante técnicas de optimización y simulación en la producción de llantas. Caso de estudio: Continental Tire Andina

Abstract

The tire industry has become a fundamental pillar for developing new processes whose main objective is to achieve a competitive advantage. Given its massive production, the most common process is linear. However, production systems are not perfect and face different problems, the most notable being line balancing. The methodology used to achieve the objective is structured in three phases. In the first phase, a time analysis is carried out in each process or subprocess of the production line that is directly involved in the tire process. In the second phase, buffers are created: the first at the input of the rebarbeo process and the second at the input of the uniformity analysis process. This causes an increase in the demand for tires to be processed, which is why it is necessary to adjust capacity by adding a TUG#2 machine, specifically dedicated to the analysis of rim 16 due to its high production volume. Finally, in the third phase, the production flow is simulated using the Flexim software and the function of the proposal is evaluated. As a result, blockages are eliminated at the system entrance in the final finishing area, at the exit of TUG machines and balancing machines. In addition, a new design is proposed that improves the flow of tires along the entire line, optimizing the location of operators, bands and stations, which increases the percentage of utilization and increases the number of tires ready for marketing. both for replacement in 612 tires and for original equipment in 303 tires.
