The objective of this research was to develop a decision model for chemical engineering students are trained in making decisions related to the Management of Production and Operations (GPO). The model is supported in discrete simulation and through this, users can pose different scenarios of operation of a typical process addressed by the chemical engineering, such as the production of bioethanol from sugarcane and evaluate how these scenarios affect production level. Model is expected to be used in the training of future chemical engineers in making decisions about GPO, facilitating experimentation with a real system by simulation. The importance of the use of simulation in training processes, using models and tools built between teachers and students, allowing break the space, time and cost to experiment with real systems and barriers and promote training in virtual environments is concluded learning.
