Abstract

This work focuses on the evaluation of the intermodal transport problems under the influence of seasonal constraints that are not usually considered on the phase of planning and sizing the fleet. Considering the superposition of two different seasonal factors along the transportation chain – first one the variation on grain production and the second one the level of water in the waterways throughout the year –, a discrete event simulation model was built to show the real effects of those constraints in the grain supply chain. So, it is possible to evaluate the impact of those constraints not only on the usage level of storages in this system, but also the number of vehicles required to transport this commodity from the Midwest of Brazil to the port. In a complex multimodal transportation system, the simulation model in this work includes roadways, waterways and seaways to transport all the cargo from farms to the final costumer. This study is composed by several scenarios to evaluate the bottlenecks in this intermodal transportation system, specially analyzing scenarios with and without seasonal constraints, as well as analysis of sensitivity of performance of equipment of loading and unloading, in which the fleet and the required stocks are substantially different if seasonality is not considered. In other words, it is possible to evaluate the risks involved when managers are making decisions if they do not take in consideration any of those seasonal constraints.
