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. - correct answer ✔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. - correct answer ✔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. -
correct answer ✔True
Which module/spreadsheet is NOT in the Advanced Process panel? - correct answer ✔Process Module.
This is in the Basic Process panel.
Why are things like Seize, Delay, Release in multiple templates? - correct answer ✔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. - correct answer ✔True
TRUE or FALSE? You are only allowed to schedule one type of failure for a particular resource. - correct
answer ✔False
Which block is NOT in the Blocks template? - correct answer ✔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. - correct answer ✔False
Which kinds of sets are allowed? - correct answer ✔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. -
correct answer ✔True
TRUE or FALSE? For easy display and organizational purposes, our Call Center simulation is divided into
several submodels. - correct answer ✔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. - correct answer ✔True
TRUE or FALSE? All of the Tech Support servers for our Call Center are equally skilled and have the same
concurrent work schedules. - correct answer ✔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. - correct answer ✔True
Consider our Call Center demo. What is the following Seize request asking for? Set, Product 1, 1,
Preferred Order, Agent - correct answer ✔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. -
correct answer ✔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? - correct answer ✔(0.3)(1) + (0.5-0.3)(3) + (1.0-0.5)(6) = 3.9
