SYSTEM SIMULATION PRACTICE AND
ANSWERS 2025
TRUE or FALSE? You can pre-assign a service time as an attribute before you actually
get to the server that you'll be using. - ANS>>True
TRUE or FALSE? If you have Create module generating one-at-a-time customer
arrivals, then it is not possible to use a different Create module with 4-at-a-time
customer arrivals. - ANS>>False
TRUE or FALSE? Fake customers can be used to schedule machine breakdowns, keep
track of which time period the simulation is currently in, and carry out other duties not
associated with actual customers. - ANS>>True
Which module/spreadsheet is NOT in the Advanced Process panel? - ANS>>Process
Module. This is in the Basic Process panel.
Why are things like Seize, Delay, Release in multiple templates? - ANS>>The Process
module does not allow us to use Seize, Delay, Release with sufficient generality.
TRUE or FALSE? You can schedule failures to occur after a random number of
customers have used a resource or after a random amount of time has passed. -
ANS>>True
TRUE or FALSE? You are only allowed to schedule one type of failure for a particular
resource. - ANS>>False
Which block is NOT in the Blocks template? - ANS>>Process block. There is no such
thing. However, the Process module is in the Basic Process panel.
TRUE or FALSE? The Queue block can connect up to the Seize module from the
Advanced Process template. - ANS>>False
Which kinds of sets are allowed? - ANS>>Resources set, counter set, entity type set,
entity picture set
TRUE or FALSE? It is possible for the resource Joey to be a member of three different
resource sets. - ANS>>True
TRUE or FALSE? For easy display and organizational purposes, our Call Center
simulation is divided into several submodels. - ANS>>True
, TRUE or FALSE? The customer arrival pattern for our Call Center changes over the day
and is therefore modeled as a nonhomogeneous Poisson proces. - ANS>>True
TRUE or FALSE? All of the Tech Support servers for our Call Center are equally skilled
and have the same concurrent work schedules. - ANS>>False
TRUE or FALSE. In our Call Center demo, fake customers are used to update a
variable that keeps track of the period of the day. - ANS>>True
Consider our Call Center demo. What is the following Seize request asking for? Set,
Product 1, 1, Preferred Order, Agent - ANS>>Grab one server from the set Product 1 in
the order listed when the set was defined, and store that guy's identity int he attribute
Agent.
TRUE or FALSE. In our inventory demo, fake customers are used to initiate a periodic
inventory review. - ANS>>True
Consider the Arena expression DISC(0.3,1,0.5,3,1.0,6) which is a discrete random
variable. What is the random variable's expected value? - ANS>>(0.3)(1) + (0.5-0.3)(3)
+ (1.0-0.5)(6) = 3.9
Consider a vanilla (s,S) = (5,12) inventory policy. If my inventory slips to 3, how many
items do I order? - ANS>>9.
Since 3<s, we order S-3 = 9
TRUE or FALSE? It's perfectly OK for a customer to go from server 1 to server 2 and
then back to server 1. - ANS>>True
TRUE or FALSE? Crazy stuff can happen if you start fooling around with multiple server
visits, service priorities, and server times. - ANS>>True
TRUE or FALSE? There are 100s of SMARTs files for you to play around with. -
ANS>>True
Modules and spreadsheets from which panels are used in the demo? - ANS>>Basic
Process, Advanced Process, Advanced Transfer
((1==1)*10) + ((1==0)*5) = ? - ANS>>10
TRUE or FALSE? You can find individual Seize, Delay, and Release modules in this
template (Advanced Process Template). - ANS>>True
Where can you find some sort of Seize? - ANS>>Within a Process module in the Basic
Process template, A seize module in the Advanced Process template, A Seize block in
the Blocks template
