A number of trial runs were performed to validate
the model an d 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 60 min. Then, there was very
little variation among the replications. With this in
mind, each simulation in our experiment was run for
1440 min after a warm-up period of 60 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 10 times. The total number of
simulation experiments performed is 2(scenarios)
10(replications) which are 20. The performance
measures collected from the simulation are given as
delivery time, transport time, throughput, and AGVs
utilization.
