Aplicação da Metodologia Seis Sigma como Fator Estratégico para Aumento da Eficiência Operacional: Estudo de Caso de uma Empresa no Setor Portuário. 2020. 102 f. Dissertação (Mestrado em Engenharia de Processos) – Universidade Federal do Pará, Belém, 2020.https://rigalileo.itegam.org.br/handle/123456789/815This work proposes the application of the Six Sigma methodology aligned with the strategic goal of a company in the port sector to increase its loading capacity by optimizing operational processes, reducing losses, and improving efficiency. The exploratory research was conducted through a case study with the implementation of the methodology in the operational processes of a port unit located in São Luís - MA. Six Sigma tools and concepts were used, with emphasis on the DMAIC method (Define, Measure, Analyze, Improve, and Control). After implementation, operational losses were reduced by 0.42 hours per ship, resulting in a potential gain of 375 hours per year, contributing to greater operational efficiency at the port and achieving the company's strategic objectives.pdf.Seis SigmaEficiência OperacionalSetor PortuárioDMAICMelhoria de ProcessosDissertação de MestradoEngenharia de Produção
