Aplicação do Ciclo PDCA como método de análise e solução de problemas para redução de falhas em carregadores de navio – estudo de caso em uma mineradora

Abstract

Today's companies are constantly looking for improvements in their productivity, so problems in the area must be vigorously tackled in order to achieve their goals, as the labor market is increasingly demanding. Based on this context, this work presents the use of the PDCA method to solve problems in the area of shipment of a mining company that we have here as an example for study. The concepts used cover topics as, belt conveyors that are large equipment inside the mining company, maintenance, because the study is based on the improvement for these activities as well as monitoring of their indicators. The use of the PDCA method also stands out due to the focus of this work, which turns to application of this methodology together with the quality tools that helped in the development of this work in order to solve problems in the area. An equipment known as CN3 was taken for analysis because of its priority and urgency in treating a chronic misalignment fault on its conveyor belt. Through the application of the PDCA method, it was possible to reduce the failures due to misalignment by 100% in the CN3, corrective maintenance expenses were 0 (zero) hours of interventions, no more failures due to the rip at the belt edge, Resulting in an increase in the availability of the equipment in 100%, that is, the entire volume of ore planned was shipped. In this way, the work is descriptive, exploratory and explanatory
