1. Explain the differences between fixed and random factors in
Design of Experiments (DoE).
2. Explain the three pillars of DoE.
3. What are the differences between replication and
repetition?
4. In plastic injection molding, temperature, time in mold, and
injection pressure each play an important role in determining the
strength of the part. At MAR Inc., experimenters are studying the
effects on part strength when the temperature is set at either
250o, 275o, or 300oF; the time in mold...
Explain and describe the key differences
between these two sets of experiments:
Sets of Experiments I: HCV Status
Experiments
In the first set of experiments, examine the blood samples of
individuals with known HCV status. There are three groups of
individuals in this experimental set: (1) individuals with chronic
hepatitis C (this includes patients known to have chronic hepatitis
C or blood donors who are known to have passed HCV onto
recipients); (2) individuals with acute hepatitis C infections or...
Explain the three types of exchange rate systems:
free-floating, managed, and fixed. Discuss the differences between
them. What are the advantages and disadvantages of each system?
Which system is the United States currently operating? Do you think
the U.S. should change the type of exchange rate system? Why or why
not?
What are the main differences between natural and
forced convection flows? In the lab experiments, explain how we did
use one experimental test rig to demonstrate the characteristics of
both flows. ?
A. Explain and describe the key differences between these two
sets of experiments (see below):
B. Also explain the the significance of having two experiments
as opposed to one experiment.
C. Identify the independent and dependent variable for these
experiments.
Sets of Experiments I: HCV Status
Experiments
In the first set of experiments, examine the blood samples of
individuals with known HCV status. There are three groups of
individuals in this experimental set: (1) individuals with chronic
hepatitis C (this...
Explain the differences between Economies of Scale and
Diseconomies of Scale and explain what factors influence over them.
In order to do so, you will have to use the concepts of Short and
Long Run average total costs. Remember that in the Short Run
Average Total Cost curve, you can find at least one of your assets
as fixed and in the Long Run Average Total Cost curve, all the
assets are considered variable, meaning that you are assuming the...
One-Factor-at-a-Time (OFAAT) and Design of Experiment
(DOE)
Per the textbook, trying to understand factors that impact the
outcomes of business process is an important aspect of improving
business operations. Conventional wisdom plans experiment
one-factor-at-a-time (OFAAT).
Compare and contrast the main advantages and disadvantages of
OFAAT and DOE and select the approach (for example, OFAAT or DOE)
that you would use in order to obtain effective business process.
Provide a rationale for your response
