18Bayesian Estimation
- In general, there are two types of approaches to
estimation of parameters - Frequentist - Estimates an unknown
parameter based only on observed data and an
adopted model - Characterized by
scientific objectivity - Bayesian - Estimates an unknown parameter
by appropriately combining prior intuition
or knowledge with information from observed data
- Characterized by subjective nature of prior
opinion - Each approach is valid when applied under
specific circumstances.Neither approach will
uniformly dominate the other
19Bayes Theorem Exercise
Many combat aircraft carry air-to-air missiles.
A warning light will notify the pilot if the
missile is defective. If the missile is
defective an alternative missile may be used or
the mission may need to be aborted. The missile
may or may not be defective when the warning
light is on. Given the warning light indicates a
bad missile - what is the probability the missile
is really defective? Approach Define Event A as
the missile is a dud. Define Event B as the
warning device signals the missile is a dud. From
product specs it is known that P(A) .0001
i.e., one missile in 10000 is a dud. P(BA)
.9998 i.e., the probability of the avionics
hardware and software detecting and reporting a
defective missile is .9998 P(Bnot A) .002
i.e., probability of a false warning is .002

Translating Diverse Criteria Into a Common Scale.
(i.e., Range in NMi, MTBF in Hours, etc.) - Utility Scores Range From 0 to 1 With 0 Being

58Observation
When development cost goes up (due to risk
resolution in order to decrease design margins),
production cost goes down.
Question How can development and production
cost be balanced?
59How to Determine Development Cost
Sum the development and production cost and graph
as a function of development cost.
60Summary of Course
- Review different Systems Engineering
sub-processes from the perspective of - Existing industry standard (i.e., current
state-of-the art) - Emerging trend not widely implemented
- Idea for improvement
61Fear Tigers Not Mice
Work to identify risks and decide how to best
handle them. In the absence of periodic focus on
risks your program teams will focus on
accomplishable tasks.
62Concluding Thoughts
Each of you can implement systems engineering
and/or risk management process improvements in
areas you are responsible for, assuming existing
company procedures do not already dictate a
procedure. When company procedures exist, a new
procedure pilot will many times be a good tack
for gaining approval to proceed. Suggestions for
improvements in areas outside your responsibility
may be considered and not implemented. Choose
wisely!
