Análise de alternativas logísticas para o transporte de cabotagem do Amazonas utilizando simulação computacional

Abstract

Cabotage is made between ports of the same country, using sea or sea with waterway. In the state of Amazonas cabotage is mainly used to transport general cargo and containers, but cargo in containers handling has the largest growth potential due to the existence of the Polo Industrial de Manaus (PIM), which makes the port city of Manaus the main cargo hub in the Northern Region. This paper proposes the simulation of alternative scenarios for cabotage in the State of Amazonas using techniques of computer simulation to do evaluation of the operational efficiency on implementation service feeder adapted to the regional context. The study characterized the cabotage in the State of Amazonas enabling the modeling of the real system in the state. From the literature concerning the concepts of service feeder and hubs ports was developed alternative scenarios for implementing these approaches in regional transport. Thus it was possible to simulate with software ARENA the models and scenarios constructed in order to verify the performance of the system. The results showed that the operational viability of the use of hubs ports and feeder service depends on the balance between the demand for container handling and the capacity of the hub port and other ports feeders supported. Therefore, the study shows that it is necessary to equate the volume of container cargo that state of Amazonas is able to generate and attract with the operational characteristics of the hub port to avoid causing unnecessary investments for creation of transport infrastructure that may be underutilized or do not support the demand required.
