The transport of grains in the Amazon region is carried out by waterways and highways, however, there are problems of congestion in the accesses and productivity of the ports that is still low. In the last decades the Brazilian bulk production has been experiencing a great growth, the search for better logistical solutions in the scope of the production flow in the shortest time and at the lowest cost, has brought a prominent role to the Amazon region. As the largest watershed in the world, its waterways have become one of the most important axes for all national production. Notwithstanding the forecast of increased production, it has become essential to develop strategic methods to ensure its viability and optimization, in this way, the main companies operating in this market already use river convoy models for flow. In the competitive scenario, ways and means were developed to improve its transport logistics, employing sufficient measures to optimize the entire process. It is known that the agricultural bulk process by push convoys is carried out by river barges. These projects were developed in a different navigation and demand scenario. In search of a more adequate solution, with the conditions of the Amazonian navigation environment and the high capacities necessary for the bulk carrier convoys, this work has the fundamental scope to elaborate on model in the fluvial convoy formation that could analyze the additional cost for convoys over 210 m, which intend to navigate in the Estreito de Breves-PA, using the possible formations that would generate a better economic viability of the fluvial convoys used in the Amazon, being the model presented in this dissertation of great importance for optimization for the formation of the convoys of push, since it could obtain the cost per ton for each formation due to the normative requirements for navigation in the region of the straits of the island of Marajó with the following results: extra pushers for convoys of 35 and 45 barges and auxiliary pushers (scouts) for the formations of 25, 35 and 45 barges, generating highly positive aspects s in the commercial scope for large companies that use this type of service.
