Dissertação (Mestrado em Engenharia de Processos) – Universidade Federal do Pará, Belém, 2019.https://rigalileo.itegam.org.br/handle/123456789/856This dissertation takes place in the fuel management of Vale S/A railroad. As the work is developed, the project phases are guided according to diagnostics, applying a cyclical and continuous improvement along with the methodologies of study for the problems encountered. In view of this, we sought to implement a continuous process improvement project for critical fuel management activities through lean tools, in order to respect the principle of employing routines, easily communicable and understood by everyone in the organization. The main results are: team engagement from 32% to 64% (staff participation in the development of improvements), reflecting the increased problem resolution of the area (794 improvements) and reduction of supply time by 16%, increase productivity by 30% of the supply flow, and practice innovation in the method of training procedures, reducing operating costs and providing quality processes.pdf.Lean ManufacturingGestão de CombustívelMelhoria ContínuaSeis SigmaPDCADissertação de MestradoEngenharias
