In Arena, a DECIDE module can route customers probabilistically or
conditionally to multiple locations.
True
In Arena, a primitive QUEUE block can connect with a PROCESS
module.
False
In Arena, you can pre-assign a service time as an attribute before
you actually get to the server that you'll be using.
True
In Arena, it's perfectly OK to have a CREATE module generating one-
at-a-time customer arrivals, while also having a different CREATE
module with4-at-a-time customer arrivals elsewhere in the model.
True
In Arena, "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.
True
What is the expected value of the Arena expression
EXPO(DISC(0.5,2,1,3))?
2.5
Suppose there are 7 people in the line called joe.queue and 2 people
in the line called tom.queue. What is the value of the following
Arena expression?
(NQ(tom.queue)>=NQ(joe.queue)) + (TNOW>−1)
1
In Arena, the SEIZE, DELAY, RELEASE functionalities are in multiple
templates.
, True
In Arena, 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.
True
In Arena, you are only allowed to schedule one type of failure for a
particular resource
False
In Arena, it is possible for the resource Joey to be a member of three
different resource sets
True
For easy display and organizational purposes, our Arena Call Center
simulation is divided into several submodels.
True
The customer arrival pattern for our Arena Call Center simulation
changes over the day and is therefore modeled as a
nonhomogeneous Poisson process.
True
All of the Tech Support servers for our Arena Call Center simulation
are equally skilled and have the same concurrent work schedules.
False
In Arena, what kind of module would you use to change an entity's
picture?
Assign
In Arena, where would you find the Expressions spreadsheet
Advanced Processes Panel
Consider the Arena Inventory model that we did in class as a demo.
Did this model allow for backlogs? YES or NO?
Yes
In an Arena PROCESS module, it is possible to do a DELAY without an
accompanying SEIZE or RELEASE.
True
