It will also be done the research and analyzis of the logistics flows in the Rio de Janeiro port terminals, it will allow the presentation of the current situation of the port terminals established in the state of Rio de Janeiro, demonstrating the current operational indexes. Besides that, it s the intention to evaluate the degree of compromising of the port terminals regarding the operations and the consequent logistic needs for the state of Rio de Janeiro and to the users states of port infrastructure. Finally the research and analyzis of the flows logístics of free import processes in Rio de Janeiro is presented, wich, through the presented analysis, will be used for operational evaluation of the processes and procedures adopted by the logistics s operators involved into referred processes, looking for determine solutions for the main detected problems.
