Aplicação da metodologia seis sigma como fator estratégico para aumento da eficiência operacional: estudo de caso de uma empresa no setor portuário

Abstract

This work proposes the application of the Six Sigma methodology iligned 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. It is an exploratory research in which the case study was carried out with the implementation of the methodology in the operational processes of the unit of a company in the port sector located in São Luís - MA. To carry out this work, Six Sigma tools and concepts were used, with emphasis on the DMAIC (Define, Measure, Analyze, Implement and Control), one of the most widespread methods into Six Sigma, which uses its various phases to organize the reasoning in the development of projects and the use of other quality and statistical tools. Going through the five phases of this method, we sought to map the main operational impacts on the efficiency of the unit and, prioritizing four of these impacts as a target in the development of Six Sigma projects, applying quality tools and statistics to analyze the causes and solutions and in the end, the improvement actions were implemented. After the implementation of this work, operational losses were reduced by 0.42 hours per ship, meaning a potential gain of 375 hours per year, contributing to obtain greater operational efficiency at the port and reach the company's strategic objectives.
