ISYE 6644 Midterm 2 with Study Questions and
100% Correct Verified Answers
What are attributes? - ✔✔Each customer passing through the system has various properties
(attributes).
What are variables? - ✔✔Unlike attributes, whose values are specific to each customer,
variables are global. If changed, it gets changed everywhere e.g. WIP
What can you do with an Assign module? - ✔✔You can change attributes and variables e.g.
entity pictures
What is the Attribute Spreadsheet? - ✔✔Keeps track of existing attributes that you might
define in an Assign module
What is the Variable Spreadsheet? - ✔✔Pretty much the same as Attribute spreadsheet
What is the Entity spreadsheet? - ✔✔Allows you to set initial picture
What are internal variables - ✔✔Arena keeps track of and continuously updates lots of stuff
as the simulation runs
Examples:
TNOW (current sim time)
NR(Barber) - # of resource Barber's servers now working
NQ(Process 1.Queue) = # of customers in that queue
Create 1.NumberOut = # of customers who have so far left the module Create 1
, What kinds of display information can you display while a simulation is running? - ✔✔Clock,
calendar, variable displays, histograms, graphs
What does the batch module do - ✔✔Combines multiple customers into one super
customer. Type = permanent means customers will lose their identities
What does separate do - ✔✔Duplicates a single entity or split multiple entities that have
been combined in a Batch module. If dealing with a permanent batch, usually use duplicate
original to get several customers all with the same attributes. If temp batch, use split to get
original attributes
Record Module - ✔✔Collect statistics when an entity passes through the module
What options do you get in the replications tab - ✔✔Number of reps
Initialize between reps
Warm-up period
Rep length
Terminating Condition
What sort of options/tab can you change in run setup? - ✔✔Replications, run speed, reports,
run control
What are some ways to handle different service times? - ✔✔1. Pre-assign the service times
as an attribute in an assign module
2. Use Assign to store each customer's arrival time as an attribute using TNOW
3. Record departure times, allowing us to get average cycle times for any of the 3 types of parts
