A number of trial runs were performed to validate the
model and to determine a proper simulation warm-up
period. First, it was observed that several statistics in the
simulation started to show a smaller variation after
about 200 min. Then, there was very little variation
among the replications. With this in mind, each
simulation in our experiment ran for 1440 min after a
warm-up period of 120 min. Statistical test using
ANOVA has shown that the replication effect did not
significantly affect the statistics collected in the simulation.
Therefore, each experiment was replicated three
times.
