Mapeamento de processos na gestão da manutenção: um estudo de caso

Abstract

In this paper a case study was conducted in a sugar-alcohol company located at the minas triangle and its goal was to evaluate the maintenance system through the DMAIC (Define, Measure, Analyze, Improve, Control) method searching for possible improvements. The maintenance process evaluated must follow a sequence of steps known as maintenance workflow, and in order to better understand the problems, a Brainstorming section (Define) was conducted and a survey was applied to a group of the company‟s members (Measure). After the qualitative analysis of the answers, quantitative data were generated and analyzed through the Pareto‟s chart. The Pareto‟s chart highlighted the two phases with the biggest error, MNT – 3.0 Planning p.1 and p.2 and MNT – 4.0 Scheduling p.1 and p.2 Planning of the weekly schedule/Daily coordination (Analyze). In order to evaluate the processes of those two phases, a process mapping was constructed and the items that caused the flaws were identified. The paper was concluded with the design of an action plan developed through the 5W1H tool, leaving suggestions for improvement in a short and medium timeframe, leaving, as an opportunity for future research, in its implementation and the fulfillment of the DMAIC cycle and also another iteration of the cycle that would lead to a continuous improvement of the process.
