A gestão de materiais de manutenção, reparo e operação apoiada pela metodologia de gerenciamento de tarefas.

Abstract

Due to the constant internal and external pressures to reduce costs, the companies are increasingly seeking viable alternatives to reduce their operating costs and increase profitability levels. Constant targets of costs reduction are the inventories held by businesses, especially those items known as MROs or Maintenance, Repair and Operation. These items besides representing a high cost for stocks, because they are mostly A rating, also pose a high risk if they are not available in the warehouse shelves at the moment that a particular device stops working. There is a great difficulty in accurately predicting the time to stop an outfit, especially for companies that have no knowledge or a specific area of maintenance. In most companies the maintenance is relegated to the background, until the machine stops working and jeopardize the entire production process of the company. It is to support inventory management that the maintenance management methodologies are increasingly seeking to interact with the industry supply companies. This interaction allows much greater accuracy in the maintenance sector that gets to know more of the industry supply and their interactions, as well as industry supply, which comes to know further in advance the maintenance sector needs. This survey conducted a case study in a great company of the mining sector with the aim of analyzing its methodology for maintenance management and its interactions with the supply sector, making more reliable restocking predictions. The results demonstrate the effectiveness of the methodology management tasks used by the company under study, after the stabilization period of the methodology was achieved considerable reduction in stock levels and higher operational availability of production equipment.
