Aplicação do método DMAIC na gestão de manutenção de materiais rodantes: um estudo de caso em uma empresa do setor ferroviário

Abstract

The search for operational efficiency, processes optimization, failures reduction and continuous improvements was fundamental for increasing the adoption of quality management and Six Sigma methodology by companies, in the railway sector was no different. Quality management is a strategic tool that promotes a systemic view of the entire company and is aligned with concepts and practices recognized worldwide. This work consists in a case study presentation, in which the DMAIC method (Define, Measure, Analyze, Implement and Control) was applied in a rolling materials maintenance management of a railway sector company. DMAIC is a method of the methodology Six Sigma, which aims to identify the deficiencies of the processes, investigate their main causes and propose improvements with a set of quality tools. This work has as its general objective analyze the impacts of applying the DMAIC method in the management of rolling materials maintenance in a company in the railway sector. The method application, in the company under study, standardized processes and reduced failures. In addition, it identified possibilities for improvements regarding the organization's strategy, acting on elementary causes, thus generating a high performance of the processes, and consequently reducing costs and rework. The study was of paramount importance in reducing locomotive damage, as it enabled a detailed analysis of the failures and, in most cases, the identification of the root of the problem.
