Aplicação dos conceitos do Lean Six Sigma em uma linha de produção de bombom

Abstract

This project aims to apply the concepts of the Lean Six Sigma methodology, respecting the steps of the DMAIC tool, with a focus on improving the mean time between failures indicator in a candy production line. The scenario found demonstrates great difficulty in reaching the target mean time between failures, which is 45 minutes, for the current step of the line, considering that the company applies the Total Productive Maintenance (TPM) methodology and divides the evolution of the processes within the TPM, in stages ranging from step 1 to 7. The weekly indicators measured over a year only reached the target a few times, preventing the line from being enabled for the next evolutionary step in the TPM. Only after achieving the goal of 45 minutes for the average time between failures, the line advanced within the TPM methodology. The target for this indicator in the next step is 60 minutes, só this project was the solution found to achieve the desired results. During the project, applying the DMAIC tool, it is noticed that after the improvements proposed by the project team are implemented, the mean time between failures target will be reached with ease, leaving room for 2 or 3 more steps of the evolution of the TPM in the line. In addition to expecting a considerable increase in TMEF results, the expectation of improvement in secondary project indicators is evident, but which, in a collateral way to its application, will benefit, such as the scrap and reprocessing indicator.
