This paper considers simulation of truck dispatching system designs using maximum expected production of the truck-shovel system as the measure of perfommnce. Two methods are utilized, multiple comparisons with the best (MCB) and the combination of MCB and the variance reduction technique known as common random numbers (CRN). These two techniques are compared via simulation experiments.The results show that the combined procedure of MCB with CRN is the superior tool to reduce the total number of replications needed to ensure the specified probability of correct selection over the finite number of designing systems.In this case study, MCB with CRN reduces the variance by 29°/0 and the number of required replications by 48Y0. Also, the MCB with CRN procedure narrowed the confidence interval by 18°/0.
