Aplicação da metodogia DMAIC na redução de rompimentos por esmagamento em máquina de papel kraftliner

Abstract

Organizations must seek improvements in their processes in order to maintain continuous production, eliminating waste that does not add value to the customer and still reduce production costs. A methodology that works with this objective is lean six sigma, which seeks through its tools to solve complex problems and generate profit for organizations. The work exposes a case study of a kraftliner paper machine with excessive disruption due to dirt. To develop this study, the DMAIC (define, measure, analyze, improve and control) was established, as it is a methodology that has structured phases with tools capable of bringing satisfactory results at the end of projects. The aim of the study is to reduce 25% of disruption due to dirt in 2021 compared to 2020, avoiding a loss of more than BRL 300,000.00. After carrying out the action plans, it was found that there was a 61% reduction in disruption, bringing savings of approximately BRL 800,000.00 for the company and that even with the monitoring of the project during 2022, it was possible to notice the operational development in the decision-making under the problem, which improved machine performance.
