Aplicação da metodologia DMAIC para o aumento de eficiência de máquinas em uma indústria de laticínios

Abstract

This paper describes a case study on the use of the DMAIC methodology to increase the efficiency of yogurt producing machines in a dairy industry. Then there is a brief contextualization of the company and presentation of the methodology used to do the work, going through all the stages of the DMAIC, which was applied in the Machines A, B and C, belonging to the family Yogurt pulp factory. In the Define stage, the project's scope, responsibility and schedule were defined. In the Measure stage, we verified the existence of the problems and defined which of them would be analyzed through graphs. In the Analyze stage, we investigated the root cause of the problems chosen for the study, using quality tools (Ishikawa Diagram, 5 Why Test and 5W2H). In the Improve stage, gains were estimated on the projects' applications, which was 1.63% efficiency for Machine B, 3.54% for Machine C and 2.06% for Machine A, and later plans were suggested to the Control stage. Finally, there is a topic with the conclusions of the study, where future actions of continuous improvement are also suggested for the company studied.
