Planejamento e projeto de uma linha de montagem com o uso de programação linear inteira binária: um estudo de caso em uma empresa fabricante de eletrodomésticos

Abstract

This paper aims to present a proposal for planning and design of a new assembly line by means of a mathematical model for the great balancing, considering the volume of sales planned for the planning horizon. The company selected for the case study is in the business of manufacturing home appliances. We developed a model of Binary Integer Linear Programming to the problem of balancing. The model was implemented in a spreadsheet, and the optimal solution obtained through the Software OpenSolver, which uses the Branch and Bound algorithm. Since the model does not include all operating constraints, developed balancing implementable optimal solutions on the basis of the model. The results show that increasing productivity occurred because there was a decrease in the number of workstations required to perform the operations compared to the existing line, and therefore optimal use of the capacity of the new line.
