The simulation model analyzed different scenarios
obtained by altering the number of vehicles available for
product movement. The residual analysis shows that the
assumptions can be satisfied for all performance
measures, so further statistical analysis can be carried
out. From the results of the analysis of variance, the
vehicle number significantly affects the average delivery
time and the average throughput at 95% confidence
level. Ordinary least-squares estimation techniques were
applied to develop models for each response variable.
Thus, the generated models are as follows:
