At a high level, how are random numbers generated in a computer? - CORRECT
ANSWER: 1. Generate pseudo-random numbers (PRNs) using a deterministic
algorithim (not really random but appears to be)
2. Generate other random variables by starting with the PRN and applying
transformations to get any other type of random variable.
Characteristics such as the priority or speed of a customer are known as ...?
A) variables
B) function values
C) entities
D) attributes
E) Activities - CORRECT ANSWER: D) attributes
How are steady-state simulations analyzed? - CORRECT ANSWER: First deal with
initialization (start-up) bias
- usually "warm up" simulation before collecting data
- failure to do so can ruin statistical analysis
Many methods for dealing with steady-state
- ex: batch means
,How are terminating solutions analyzed? - CORRECT ANSWER: Usually analyzed via
independent replications.
1. Make independent runs (replications) of the simulation, each under identical
conditions
2. Sample means from each replication are assumed to be approximately i.i.d. normal
3. Use classical statistics techniques on the i.i.d. sample means (not on the original
observations)
How many simulation languages are there? - CORRECT ANSWER: More than 100
commercial languages in the ether.
If the f(x) is position, the first derivative is the velocity, what is the second derivative? -
CORRECT ANSWER: acceleration
In terms of simulations origins in manufacturing, what are some of the ways that
simulation was/is used? - CORRECT ANSWER: 1. Calculated the movement of parts
and interaction of system components.
2. Evaluates part flow thru the system
3. Examines conflicting demand for resources
4. Studies contemplated changes before their introduction
5. Prevent design blunders
Inscribe a circle in a unit square and toss 1000 random darts at the square. Suppose
that 800 of those darts land in the circle. Using the technology developed in this lesson,
what is the resulting estimate for 𝜋
A) -3.2
B) 2.8
C) 3.0
, D) 3.2
E) 4.0 - CORRECT ANSWER: D) 3.2
Since the estimate 𝜋̂ = 4 x (proportion in circle). Note that (a) is the University of
Georgia answer, and is completely incorrect.
Let's simulate a bank that closes at 4:30 p.m. What kind of simulation approach would
you take?
A) Steady-state simulation
B) Terminating simulation
C) Arnold SChwarzenegger simulation
D) I'm from the university of georgia. What is simulation? and what is a bank? -
CORRECT ANSWER: B) Terminating Simulation
Let's take a bunch of independent observations from a "well-behaved" distribution. The
Central Limit Theorem says that the standardized sample mean of those observations
converges to what distribution? - CORRECT ANSWER: Normal
Regarding probability, events are independent when what definition is met? -
CORRECT ANSWER: If the probability of A intersect B equals P of a times P of B then A
and B are independent events.
Suppose customers to a barber shop show up at times 4 and 11. Moreover, suppose
that it takes the barber 12 minutes to serve customer 1 and then 14 minutes to serve
customer 2. When does customer 2 leave the barber?
A) 18
B) 25
C) 30
