Aplicação do Evento Kaizen no Processo de Troca de Correia Transportadora: um estudo de caso na mineradora Vale S.A

Abstract

Competitiveness is the power that the organization has of fulfilling its mission and objectives more efficiently than other competing organizations, and this is something that is gaining tremendous force among big companies. In order to achieve the highest possible efficiency, it is necessary to adopt ideas to increase productivity with the implementation of improvements. Thus, the present work proposes to analyze the effectiveness of the Kaizen Event for the solution of problems during the exchange of conveyor belts comparing the literature with the practical development in a mining company. The increased use of the Kaizen Event in organizations for problem solving is apparent. Thus, analyzing the use of the Kaizen Event serves as a foundation for other organizations to adopt this method in order to remain in the market. This work shows how the event is described in the literature and how it was developed in practice, based on the analysis of a case study, making comparisons between events. In order to obtain a basis for the practical analysis of the Kaizen event, some quality tools were applied, such as Brainstorming, Pareto Graph, Ishikawa Diagram and GUT Matrix. Thus, the results obtained show the nonconformity between theory and practice in the promotion of events like this one. In the end, it is concluded that the event was well accomplished in regard to achieving its objectives. The deployed improvement achieved its goal by providing more safety in belt changes
