This paper uses System Dynamics modeling and process simulation to explore coordination in two logistic processes(procurement and production) of the supply chain of an ethanol plant. In that sense, three production scenarios areevaluated to identify: a) stock movement according to current inventory policies, and b) the critical variables affectingthe coordination for these two processes. Since the main goal in the company is to meet customer demand, thisresearch incorporates sales forecasting, and four performance indicators to evaluate the state of the processes: 1)average percentage of demand satisfaction, 2) maximum amount of ethanol in excess, 3) available ethanol at the endof the year, and 4) inventory costs. To model the case study, the change in production yield and specific constraintsfor the chain are considered. The simulation results show that System Dynamics modeling can be used to observe theeffects of policies on inventory, and meeting the demand in a real system. It also can define the coordination for asupply chain and give information to improve it. The developed model uses STELLA® software to simulate the logisticprocesses and execute the evaluation employing the performance indicators.
