You have performed queueing analysis. You plan to use these queueing results to verify your simulation model. You then run 10 replications of the simulation each with a run length of 5 hours (see the experiment in the attached simulation model). However, your simulation and queueing results don't quite match. In particular, your queueing calculations for the overall NIS and TIS do not fall within the 95% confidence interval of the corresponding simulation results.

Identify ALL possible explanations/reasons for this mismatch.

Fix the issues identified in part (a). Clearly show/explain how you fixed each issue.
