Second (STOCK, 1998), logistic reversa is an area with great amplitude for study is inserted in logistic enterprise, that in turn is inserted in the management of the suppliment chain, whose its main activity is to put into motion corresponding products, goods and information they, for all the productive chain. In contrast of logistic the traditional one that acts in the flow of the exit of the products since the beginning of the manufacture until the o consumption of the finished product, aiming at to take care of to the customer of agile form with an excellent level of service, logistic reversa is worried as it will be made the return of the products, materials and parts for the origin company. In the concept of Rogers & Tibben-Lembke (1999) is considered as: the process of planning, implantation and control of flow-efficient and low cost of materials, supply of processes, supply of products, supply of finished products as well as information related, since the consumption point until the one of origin, with the purpose to recoup the value or to make the discarding of the adequate form. The efficiency of Logistic reversa can present good or bad results, this if must some critical factors that condition the system (Rogers and Tibben-Lembke, 1999): Controls of entrances (GateKeeping); Mapping and formalizao of the process; Time of cycles of the products; Systems of information; e? Relation between customer and supplier. It is necessary to correctly identify the state of the materials that return, in order to facilitate to the flow reverse and to guarantee that its reutilizao can occur of adequate form and hinder that material inadequate they generate unnecessary expenditures and services. A logistic system of reversa must be brought up to date well, therefore m unbalanced system can bring difficulties in the course of the process.
