ANÁLISE DO PROCESSAMENTO DE PERFIS METÁLICOS: APLICAÇÃO DE TEORIA DE FILAS EM UMA INDÚSTRIA DE ESQUADRIAS

Abstract

Production systems often face bottlenecks and waiting times due to variability in the arrival of materials, the availability of machines or limited labor. In the framing industry, due to the requirement for high productivity and quality as well as the complexity of the mechanical profile forming process, queuing theory is a tool that can be used to size the process and identify bottlenecks. Therefore, the present study aimed to analyze the processing flow of metal profiles in order to identify accumulations in the operation, and suggest new scenarios through simulations to optimize the process. Data analysis revealed the existence of a bottleneck in the production process of a profile of the studied system. In view of this, 4 scenarios were simulated in Software Arena with the aim of finding an efficient configuration to ensure good functioning of the system. The best alternative found to significantly reduce the crowding of parts in the queue and the waiting time consisted of adding a new machine to produce only the bottleneck product, in this way it is expected that with the data provided by the work the company will be able to assess the risks and advantages of adopting the suggestion.
