Contribuição da metodologia seis sigma para diminuição do índice de avariados: um estudo de caso em uma empresa de distribuição de gás

Abstract

The concept of quality has evolved along with the changes experienced in the industry. As a result, quality control has become an essential part of any production, aiming to ensure the competitiveness and relevance of a company. The Six Sigma methodology studies the internal processes of a company, and then uses the facts and data obtained in the search for changes that will generate process improvements. In this sense, the present work aims to present the ways the Six Sigma methodology can contribute to reducing the number of issues in cooking gas cylinders in an industry in the gas segment. The research was conducted in the production sector of a liquefied petroleum gas (LPG) distribution company. The work was carried out at a unit of the group in São José dos Campos, São Paulo, within the P13 (cooking gas) cylinder filling sector. The study carried out a collection of qualitative data in order to delimit the needs of the sector to be studied. The method used was the case study. After the study, it was possible to map, measure, analyze and find the problems generated in the process. The filling process was better understood by the company's own team and employees were trained, generating greater precision in identifying leaks in P13 cylinders. At the end of the survey, the rate of damage to cylinders P13 was reduced by 39% compared to the company's rate at the beginning of the project.
