In this paper, the simulation speeds of four different process simulators – BioWin, GPS-X, WEST and STOAT - are tested for a simple MLE process. In addition, more complex models were tested using the BioWin and GPS-X simulators. The speed tests were carried out for steady-state and 14-day dynamic simulations. It was found that all simulators could carry out simulations in less than 6 minutes for the MLE process. More complex models incorporating IFAS ran much slower and the extra time required for this must be considered when carrying out process evaluations. Finally, it is noted that simulation speed is not the primary concern for process modeling, but that it is model accuracy that is of paramount importance.
