Abstract
There are several challenges involving the representation or an ore loading port system on a simulation package. This kind of port handles bulky material, much more adequately represented by continuous flow then discrete flow, as in opposite to the case of a container-handling port. This paper addresses some challenges faced such as the navigation restrictions to enter/leave the berth, the stacker/reclaimer position in the ore pile, the impact of meeting product mix requirements in the delivery and the loading plan for the ships. When these aspects are not represented under the correct level of detail, the model can present poor results. Also, results reporting challenges are addressed in this paper. The modeling approach of each of these aspects is presented, and the experimentation in the case of Porto do Açu, located at Rio de Janeiro, is addressed with the purpose of evaluating the efficiency of the solutions proposed.
