Aplicações em modelos para gestão de materiais e estoque em uma empresa de remanufatura

Abstract

Remanufacture can be defined as the industrial process where products worn, broken or used are restored getting a new life. Currently, many companies remanufactured products, driven by economic or environmental benefits, or by the force of law. Performing materials management and inventory in this environment with peculiar characteristics efficiently, it is necessary to contain waste with excess inventory or lack of material for production. In addition, the purchasing department holds an important position in most organizations, as parts, components and supplies can represent 40-60% of the final value of sales of any product. Thus, the objective of this work is the proposition and implementation of inventory management models in a remanufacturing company of fire extinguishers and analyze the efficiency of these through the expenses accumulated during one quarter. Based on preliminary analysis of the historical consumption series of selected materials, three propositions were suggested. The results show that when we analyzed the implementation of the proposals in material individually, there were cost reductions and better regularity in buying some, and in others, the proposals have not brought benefits. With the results, it is suggested that the application of the propositions, even partially for some materials, can help to increase the company's competitiveness with the availability of capital that was previously allocated to the purchase of these.
