ISYE SIM ARENA Week 6, 7
Consider a vanilla (s,S) = (five,12) inventory policy. If my stock slips to three, how many items
do I order?
A) 5
b) 12
c) 9
d) 7 - ANS-c) nine
Consider our Call Center demo. What is the subsequent Seize request asking for? Set, Product
1, 1, Preferred Order, Agent
a) Grab one server from the set Product 1 inside the order indexed whilst the set was described,
and store that guy's identification inside the attribute Agent
b) Grab a random server from the set Product 1 and keep that guy's identification within the
attribute Agent
c) Grab a random Agent from the set Product 1 and shop that man's identity in Preferred Order
d) Set the fee of the variable Product 1 equal to at least one. Do this in Preferred Order (i.E.,
with excessive precedence), and then store that fee in the attribute Agent - ANS-a) Grab one
server from the set Product 1 inside the order indexed whilst the set changed into described,
and save that man's identification inside the characteristic Agent.
Consider the Arena expression DISC(0.3, 1, 0.5, three, 1.Zero, 6), which is a discrete random
variable. What is that this random variable's expected cost? - ANS-0.3 -> 0.5 -> 1.0 is a cdf so
the probabilities are sincerely 0.3, 0.2, 0.5
zero.3 * 1 + 0.2 * 3 + zero.5 * 6 = three.9
From a Create-Process-Dispose module, click on within the Process module and select the
"Seize Delay Release" option from the Action drop-down. Add 1 resource from the Resources
menu, click adequate and run this system. What do you see?
A) I see little men running from left to right with an occasional line forming over the Process
module
b) I see little men walking round however no lines
c) I do not see any movement - ANS-a) I see little men walking from left to proper with an
occasional line forming over the Process module
Go to the Basic Process template and drag and drop Create-Process-Dispose modules in that
order. They need to join mechanically. The "Connect" button connects the modules properly.
Now run the simulation by way of hitting the "Go" button. At this factor you ought to see little
guys getting generated and flowing from left to right, however do you notice lines forming?
A) Yes, I see long strains with angry customers
, b) No, I don't see any lines - ANS-b) No, I do not see any traces
Go to the Basic Process template and drop and drag a Create module over the primary display
screen. Now click on into the module. What do you spot?
A) A field for "Time Between Arrivals
b) A area for time gadgets
c) A subject for "Entities per Arrival"
d) A field for "First Creation"
e) All of the above - ANS-e) All of the above
If I wanted to make five runs of the simulation, every lasting 100 hours, what would I do inside
the Run Setup menu?
A) Set Number of Replications = 5, Replication Length = a hundred
b) Set Number of Replications = a hundred, Replication Length = 5
c) Set Number of Replications = 5, Replication Length = 5
d) Set Number of Replications = one hundred, Replication Length = one hundred
e) Set Number of Replications = 5, Replication Length = countless
PreviousNext - ANS-a) Set Number of Replications = 5, Replication Length = one hundred
If you run the thing for some time, you may see that the transform Station gets pretty clogged up
every once in a while - probable due to the fact the carrier instances are EXPO(45) minutes.
Let's assume that management has noticed this as nicely and decides to upgrade that station so
that the carrier times are now EXPO(10). Go in advance and make this alteration and touch
upon what you see.
A) There are nonetheless very lengthy traces at Rework nearly all the time
b) There are occasionally extremely lengthy lines at Rework
c) There are every now and then short strains, however long lines are very rare
d) There is by no means ever any line at Rework - ANS-c) There are sometimes brief strains,
but long strains are very rare
Joe is a purchaser who wishes to visit Point A with opportunity 0.5, Point B with chance zero.2,
and Point C with possibility zero.Three - which Decide module choice might he use to do so?
A) 2-way by hazard
b) n-manner via chance
c) 2-way by way of situation
d) n-way via situation - ANS-b) n-manner via danger
Model a single-server queueing system (e.G., a barber store) with first-in-first-out queueing
precedence. Let the interarrivals be i.I.D. Exponential with an average of 10 mins, EXPO(10),
and let the offerings be i.I.D. TRIA(five,eight,eleven) with the gadgets in mins.
What is the % of time that the server is busy?
A) 8
b) 20
c) 50
