Homework 9
SUP Chapter 9, Part III
1. For the Kid’s World entertainment park model from chapter 6, the simulation appears
to stabilize almost immediately and typically only has around one person in it. A one
hour warm-up period was selected.
a. The average ticket queue length is: 0.0035795
The maximum length is: 3
b. The average number of customers completing ticketing per hour is: 24.09
c. The average utilization of cashiers is: 33.37
2. For the Southern California Airline check-in facility in chapter 6, the 90% confidence
interval for each of the ticketing queues after 15 replication of 100 hours is:
E Ticket Queue: [0.298 to 0.346]
P Ticket Queue: [1.041 to 1.261]
T Ticket Queue: [1.233 to 1.497]
3. For the DumpOnMe model in chapter 6, the 90% confidence interval for the average
number of trucks loaded per day is [117.316 to 117.814].
4. There is some change in the steady-state boundary when the random number seed
(STREAM) is changed. For three different seeds, the steady state boundary drifted by
about five hours.
5. For the NoWaitBurger model from chapter 6, the comparison of the two
configurations shows that the single queue model, while having approximately the
same total throughput as the dual queue model (460 exits over 100 hours) has slightly
lower average queue sizes (10.94 compared to 13.87), and therefore is preferable.
