A simulation model was developed for ingot delivery process to provide an analytical tool for the investigation of different dispatching policies. As the first step, the simulation model was successfully validated against the given actual production area. A simulation experiment was designed as the next step and all the necessary statistical tests were conducted. Even though the results of the experiment showed that the single area discipline and priority rule were superior to others in terms of the measured variables, the economic dispatching rule should not be neglected. The effect of the economic rule is the reduction of engine trips, which means that the rule minimizes the engine costs, whereas the priority rule minimizes the delay costs. Therefore, the optimum policy may be a combination of these two rules if one's objective is to minimize the total operating cost. Sensivity tests were performed on the percent delivered within 10 percent over bogey track times, and the results showed that the system was indeed very sensitive to changes in number of strippers, number of drags of buggies, and mean track times.
