Programação matemática aplicada ao balanceamento de uma linha de montagem de tratores

Abstract

The balancing of assembly lines emerged as a possible proposal to optimize production lines, resulting in increased productivity. This was done through mathematical models aiming at an equalized processing time across workstations and involved workers. This research project considered the conditions and characteristics of five seven workstations in an assembly line of tractors in the region of Curitiba-PR. These workstations are grouped around the bottleneck station of the line. Based on the information obtained, the existing precedence relationships between performed tasks were established. It was considered 21 models, which together represent 100% of the assembly line production mix for the Small category. The main objective was to find a more balanced solution of processing times across workstations by the repositioning of tasks, leading to a reduction of the bottlenecks of the line, as well as the improvement of the line indicators reaching increases of about 13% in line productivity from the change in the arrangement of two line tasks.
