Purpose and Problems
What does the output mean?
- How are we going to estimate the mean no. of customers waiting and their mean waiting time?
If ? (denote the mean no. of customers waiting) is an unknown which we are trying to estimate, then a single simulation run constitutes only a SINGLE OBSERVATION of ?.
Before drawing conclusion based on output data, a proper statistical analysis is required. The purpose is to acquire some assurance that these estimates are sufficiently accurate for the proposed use of the model.
