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

Abstract

This work aims to present the development and application of a mathematical model, based on integer nonlinear programming, to assist in balancing an assembly line. We take into account the operation times, production rates and the space avaailable for the allocation of operators and equipment. The model seeks to minimize the assembly line´s cycle time, by determining the number of operators in each operation and the adequate production rate. To implement the model, we used microsoft excel software by means of the solver tool. The case study was carried out in a company specializing in the production of footwear. After calculating the optimum balance, the results were used as a basis for the design of a new layout. The results showed that there was a considerable reduction of cycle time, a decrease in the line idleness and better use of available space.
