Balanceamento de uma linha de montagem com o uso de programação não linear inteira: um estudo de caso em uma empresa calçadista

Abstract

This paper aims to present the study and research to create a mathematical model based on integer nonlinear programming, for use in balancing problem in an assembly line. The use of this model defines the optimal solution, taking into account the limitation of the belt assembly and use more than 85% of the workforce. The case study was conducted in a company that specializes in footwear production. To implement the model we used the software Microsoft Office Excel 2007 through the Solver tool, which uses the generalized reduced gradient algorithm. After calculating the optimal balancing responses were used as a basis for the design of the physical layout. The results show that there was a considerable reduction of the cycle time, a decrease in the idle line, and a greater utilization of the structure.
