Desenvolvimento de modelo de sele？？o de materiais metálicos aplicando uma abordagem logística : o caso de empresas do setor minerometalúrgico

logistics has become a decisive process for the survival of companies. logistic aspects are responsible for the flow of materials and information from the supplier to the consumer, and have a direct impact on the performance of companies, as well as on the costs of the products and services they offer. this is enough to justify the addition of logistic aspects as tools for analysis and material selection. this work aims at presenting the development of a model for the selection of metallic material, which considers the logistic aspects on the decision process. for this reason, we have used an adaptation of the pert net (program evaluation and review technique), relating indicators of variables from material selection with those from logistics. for the purpose of validation, we then implemented the model and presented it to experts of the mining-metallurgical sector. these experts had previously reported a lack of management systems that support the selection process relating to material and logistic information. as a result, they considered the proposed model to be an important instrument for undertaking managerial decisions.
