Question 5
a. A field for “Time Between Arrivals” (i.e., the interarrival time distribution)
b. A field for time units (for the interarrival times).
c. A field for “Entities per Arrival” (i.e., how many customers show up at a
time).

a. Attribute spreadsheet (which concerns user-defined properties that
customers can have, e.g., height, weight, etc.).
b. Entity spreadsheet (which lists types of customers).
c. Queue spreadsheet (which lists the various queues in the system).
d. Resource spreadsheet (which gives properties of the various servers).
Question 9
Correct!
b. You won’t see any customers leaving (at least, after the first customer),
and the line will start to get pretty big (and eventually, Arena may give you
an error because the number of customers in the system will exceed the
student version’s limits).
a. Pretty much the same nice behavior as in the previous problem.
Question 8
a. 50% of all customers go to the Process module named “men shopping”
and 50% go to “women shopping”.
b. The Decide block changes the entity’s picture from a man to a woman
with probability 50%.

Question 12
Question 13
a. The eventual tip is determined in the Assign module, and the queue is
ordered by highest tip amount using the Queue spreadsheet.
b. The eventual tip is determined in the Assign module, and the queue is
ordered by highest tip amount using the “Priority” field of the Process
module.
c. The Barber’s service time depends on the amount of the tip.

Question 17
Question 16
a. The customer either goes to Process 1 with 50% probability or Process
2 w.p. 50%.
b. The logical expression “NQ(process 1.queue) < NQ(process 2.queue)”
checks to see if Process 1’s queue is smaller than Process 2’s.
c. The logical expression “NQ(process 1.queue) < NQ(process 2.queue)”
returns a value of either 0 (False) or 1 (True); if True, then the customer
goes to Resource 1 in Process 1.
d. The logical expression “NQ(process 1.queue) < NQ(process 2.queue)”
returns a value of either 0 (False) or 1 (True); if True, then the customer
goes to Resource 2 in Process 2.

Correct!

c. It fits a probability distribution to data, e.g., are the observed interarrival
times exponential?
d. It keeps track of the current number of people in a queue.
