Análise e solução de problemas em uma linha de produção através do método DMAIC

Abstract

This paper presents a case study with quantitative aspect, analyzing the application of the DMAIC tool in a Kaizen project with the main objective of reducing the cycle time of a production cell of face mask respirators and, consequently, increase the average productivity per hour to ensure compliance with the monthly production demand. Production cell works manually on a secondary sector industry, located in the Manaus Free Trade Zone. To achieve this goal, a detailed process analysis was conducted, identifying the bottlenecks and opportunities for improvement. Next, it was necessary to implement corrective actions to ensure the improvement of the work center. The results appreciated that the application of these tools contributed to the improvement of the production performance, with an 8% reduction in cycle time. In addition, it was possible to reduce process waste, with a 1% reduction in losses related to poor quality inputs.
