True or False? All the Tech Support servers for our Call Center are equally skilled and
have the same concurrent work schedules - ✔️✔️False.
-Some of the workers are more talented than others.
- All the servers have different schedules
True or False? In the Call Center demo, fake customers are used to update a variable
that keeps track of the period of the day - ✔️✔️True
Consider our Call Center demo, What is the following Seize request asking for? Set,
Product 1, 1, Preferred Order, Agent. - ✔️✔️Grab a random server from the set
Product 1 and store the guy's identity in the attribute Agent
Which module/spreadsheet is NOT in the Advanced Process panel? - ✔️✔️Process
Model
- The process model is in the Basic Process panel.
Advanced Process Panel
-Seize module
-Delay module
-Release module
-Expression spreadsheets
-Failure spreadsheets
Why are things like Seize, Delay, Release in multiple templates? - ✔️✔️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. - ✔️✔️True
True or False? You are only allowed to schedule one type of failure for a particular
resource. - ✔️✔️False
Which block is NOT in the Blocks template? - ✔️✔️Process Block
- No such thing, but the Process module is in the Basic Process panel
Blocks template:
- Seize block
- Delay block
- Release block
, - Alter block
- Queue block
True or False? The Queue block can connect up to the Seize module from the
Advanced Process template. - ✔️✔️False
Which kinds of sets are allowed? - ✔️✔️- Resource 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 - ✔️✔️True
True or False? For easy display and organizational purposes, our Call Center simulation
is divided into several submodules. - ✔️✔️True
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 - ✔️✔️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. - ✔️✔️False
True or False. In our Inventory demo, fake customers are used to initiate a periodic
inventory review. - ✔️✔️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? - ✔️✔️(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? - ✔️✔️Since 3 < s, we order S - 3 then 12-3 = 9
What is the value of this logic expression ((1 == 1) * 10) + ((1==0) * 5)? - ✔️✔️Since
"1==1" is true and "1==0" is false. we have
((1==1) * 10) + ((1==0) * 5) = (1*10) + (0*5) = 10
True or False? You can find individual Seize, Delay, and Release module in this
template. - ✔️✔️True
