Gestão de estoque de produtos de manutenção, reparo e operação

Abstract

Inventory Management is among the most important challenges in an organization. Maintenance, repair and operation inventory products may represent the biggest part of invested money and gross sales in a year. Having a part at the correct time assuring a quality service level to the customer, regarding low costs and keeping a short inventory, demands a straight and firm inventory policy. Based on actual datas, it was analysed the products and its demand, sharing them as product family and applying the ABC Curve. Among the available policies to the inventory control, we choose the Order Point System, to determine the best time to buy replacing parts for the inventory and to keep them for the safety stock. Comparing to the actual scenario which does not apply any policy, and its replacement is based on a critical analysis of the engineering department, this implementation leads to optimize the inventory control and specially to reduce the big harm caused by a long lead time, which may cause on stock-out and low service level. Both, Order Point System and Safety Inventory suggests a stock replacement when stock levels falls to a set quantity, based on demands past reports, error prediction and safety inventory to ensure service level of 85%. We conclude that the proposed method is effective, showing the best point to replace the stock to each product, reducing stock-out and optimizing service level.
