The main goal of this dissertation is to design and implementation of an Operational Simulation Model (OSM) of the handling of raw material in an Integrated Steelmaking Plant, considering operations of receiving, unloading, stocking, handling and supplying the different raw materials related to the production process with an operational perspective. The aim of this focus is to help in the decision making of the team controlling the ore inventory. The construction of this computer model was based on the methodological framework developed by Coelho, which passed through problem formulation, planning and elaboration of a detailed specification of the model. The OSM showed that most of the valid concepts for simulations with a strategic focus do not present relevance from an operational point of view. The advantage of the OSM is the fact that it is not random or stochastic, but deterministic. The methodology allowed the model elaboration with a minimum effort and great consistency. The results of scenarios with scheduled equipment stops have shown the simulator s flexibility, with previous identification of bottlenecks and allowed the decision making of corrective actions for avoid them on real situations. The filling of the stockyard map using results of consistent scenarios was a great advance in order to automate this activity. The correct behaviour of the simulator allowed the raw material yard team to consider the well succeeded study.
