2024 COMPLETE 100 QUESTIONS
AND CORRECT ANSWERS!!
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. - ANSWERTrue
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. - ANSWERFalse
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. - ANSWERTrue
Which module/spreadsheet is NOT in the Advanced Process panel? -
ANSWERProcess Module. This is in the Basic Process panel.
Why are things like Seize, Delay, Release in multiple templates? - ANSWERThe
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. -
ANSWERTrue
TRUE or FALSE? You are only allowed to schedule one type of failure for a
particular resource. - ANSWERFalse
Which block is NOT in the Blocks template? - ANSWERProcess 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. - ANSWERFalse
Which kinds of sets are allowed? - ANSWERResources 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. - ANSWERTrue
TRUE or FALSE? For easy display and organizational purposes, our Call Center
simulation is divided into several submodels. - ANSWERTrue
, TRUE or FALSE? The customer arrival pattern for our Call Center changes over the
day and is therefore modeled as a nonhomogeneous Poisson proces. -
ANSWERTrue
TRUE or FALSE? All of the Tech Support servers for our Call Center are equally
skilled and have the same concurrent work schedules. - ANSWERFalse
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. - ANSWERTrue
Consider our Call Center demo. What is the following Seize request asking for? Set,
Product 1, 1, Preferred Order, Agent - ANSWERGrab 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. - ANSWERTrue
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? - ANSWER(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? - ANSWER9.
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. - ANSWERTrue
A sequence must consist of unique visitation locations.... no repeat visits! -
ANSWERFalse
You could use the Advanced Set functionality to define a "Set of Sequences" -
ANSWERTrue
The name of the automatically supplied ARENA attribute that stores a particular
entity's sequence is Entity.Sequence? - ANSWERTrue
TRUE or FALSE? You SEIZE-DELAY-RELEASE a conveyor. - ANSWERFalse
An ENTER module is usually paired with what other module? - ANSWERLEAVE
Which property is not desirable for a good pseudo-random number generator? -
ANSWERWe must be able to look up the series of PRNs from a table.
TRUE or FALSE? Crazy stuff can happen if you start fooling around with multiple
server visits, service priorities, and server times. - ANSWERTrue
