◉ Consider our Call Center demo. What is the following Seize
request asking for? Set, Product 1, 1, Preferred Order, Agent
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.
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?
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?
Answer: 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.
Answer: True
◉ TRUE or FALSE? Crazy stuff can happen if you start fooling around
with multiple server visits, service priorities, and server times.
Answer: True
◉ TRUE or FALSE? There are 100s of SMARTs files for you to play
around with.
Answer: True
◉ Modules and spreadsheets from which panels are used in the
demo?
Answer: Basic Process, Advanced Process, Advanced Transfer
◉ ((1==1)*10) + ((1==0)*5) = ?
Answer: 10
◉ TRUE or FALSE? You can find individual Seize, Delay, and Release
modules in this template (Advanced Process Template).
, Answer: True
◉ Where can you find some sort of Seize?
Answer: Within a Process module in the Basic Process template, A
seize module in the Advanced Process template, A Seize block in the
Blocks template
◉ Where can you set the buffer size of a certain queue?
Answer: In a Queue block in the Blocks template
◉ TRUE or FALSE? It's possible to request servers in a set randomly,
cyclically, or according to some priority characteristic (such as the
order in which they are placed in the set).
Answer: True
◉ What would I do to change the lead time of orders from my
supplier to UNIF(0,1) days (which happens to be a little faster than
the current lead time)?
Answer: Go to the Expression spreadsheet in the Advanced Process
template and change the expression Delivery Lag to UNIF(0,1). OR
Go to the "Wait for Delivery" Delay module in the main program and
change the expression Delivery Lag to UNIF(0,1)
