Operational Research: Application of the Arena Software for the Optimization of the Inox Tower Manufacturing Process

摘要

This study aims to use the operational research techniques to seek improvements in the performance of the production of stainlesssteel towers for bodyguards in a Brazilian microenterprise in the state of Minas Gerais. The data obtained through the process mapping and the chronoanalysis were treated through the statistical control of the process and later in the Arena Student software 14 for the simulation of the current and proposed scenarios. During the study, it was found that many interruptions occurred during the production process, mainly caused by the lack of site organization, materials and tools, and machine setup. With this, the alternative presented for the optimization of process time was the application of the FacPlan method and the restructuring of tools. The results of the simulation of the proposed scenario showed a reduction of 13 minutes in each batch of towers, increasing the productive capacity of the company to 163 towers/month.
