A utilização do modelo de simulação computacional para análise e modificação de um sistema de produção de pinturas automotivas

Abstract

This paper describes the use of computer simulation applied to the factory environment for an automotive paintshop, in order to analyze proposals for future modification in the factory, to meet a new level of production demand. The painting process occurs on intermittently production line, with conveying by automatic cranes. The flow shop system consists mainly of blasting, e-coat (electrodeposition) and top-coat (powder) painting operations. The challenge consists of a structured analysis of the production process using scientific methods, in this case the computer simulation, and not only the tacit knowledge of the company's managers, aiming fastness and solid foundation for making decisions with regard to different market scenarios. The solution was sought considering the knowledge of experts who work in the system, simultaneously to the analysis by production simulation. The research-action methodology was applied as a structure for the computer simulation and modeling. The simulation software used was the Tecnomatix Plant Simulation, from Siemens Company. Considering the results, a reduction of 64% was achieved on the investment required to the proposed capacity increase.
