ISYE6644 (Simulation) Midterm 1
At a high degree, how are random numbers generated in a computer? - ANS-1. Generate
pseudo-random numbers (PRNs) the usage of a deterministic algorithim (now not truely random
however seems to be)
2. Generate other random variables by beginning with the PRN and applying variations to get
any other form of random variable.
Characteristics inclusive of the priority or velocity of a consumer are known as ...?
A) variables
B) characteristic values
C) entities
D) attributes
E) Activities - ANS-D) attributes
How are regular-nation simulations analyzed? - ANS-First address initialization (start-up) bias
- generally "warm up" simulation earlier than accumulating information
- failure to do so can spoil statistical evaluation
Many strategies for dealing with regular-kingdom
- ex: batch means
How are terminating solutions analyzed? - ANS-Usually analyzed via independent replications.
1. Make independent runs (replications) of the simulation, each beneath identical conditions
2. Sample way from each replication are assumed to be approximately i.I.D. Regular
three. Use classical information techniques on the i.I.D. Sample means (not on the unique
observations)
How many simulation languages are there? - ANS-More than 100 industrial languages within
the ether.
If the f(x) is position, the first derivative is the velocity, what's the second by-product? -
ANS-acceleration
In phrases of simulations origins in manufacturing, what are some of the approaches that
simulation turned into/is used? - ANS-1. Calculated the movement of parts and interaction of
system additives.
2. Evaluates part glide through the machine
three. Examines conflicting call for for resources
4. Studies pondered modifications before their introduction
, 5. Prevent design mistakes
Inscribe a circle in a unit rectangular and toss one thousand random darts at the square.
Suppose that 800 of those darts land within the circle. Using the technology developed in this
lesson, what is the resulting estimate for 𝜋
A) -3.2
B) 2.8
C) 3.Zero
D) three.2
E) 4.Zero - ANS-D) 3.2
Since the estimate 𝜋̂ = four x (proportion in circle). Note that (a) is the University of Georgia
solution, and is absolutely incorrect.
Let's simulate a financial institution that closes at 4:30 p.M. What sort of simulation method
could you take?
A) Steady-kingdom simulation
B) Terminating simulation
C) Arnold SChwarzenegger simulation
D) I'm from the university of georgia. What is simulation? And what's a financial institution? -
ANS-B) Terminating Simulation
Let's take a group of independent observations from a "properly-behaved" distribution. The
Central Limit Theorem says that the standardized pattern suggest of those observations
converges to what distribution? - ANS-Normal
Regarding chance, occasions are unbiased while what definition is met? - ANS-If the possibility
of A intersect B equals P of a times P of B then A and B are independent activities.
Suppose customers to a barber save show up at times 4 and eleven. Moreover, assume that it
takes the barber 12 mins to serve customer 1 and then 14 minutes to serve customer 2. When
does purchaser 2 depart the barber?
A) 18
B) 25
C) 30
D) 40 - ANS-C) 30 - Since client 2's service starts most effective when consumer 1 leaves,
which takes place at time four + 12 = sixteen.
Suppose that we're using some estimator 𝑇 to estimate an unknown parameter 𝜃. Further think
that 𝑇 has a bias of three and a variance of 5. What is 𝑇's mean squared error? - ANS-MSE =
𝖡𝗂𝖺𝗌2 + Variance = 14.
