<<That is possible, but the main goal is to

point.<br><br>Here I must take exception. <br><br>Fuzzy Logic does
not deal with uncertainty. Rather it deals with
imprecision. <br>The two are not the same. If uncertainty is
the issue, then Bayesian and probabilistic reasoning
is what is needed.<br><br>FL deals with imprecision
in both specification and in data precision. As was
pointed out, there<br>are many FL introductory texts
books/webpages<br>that will make this point.<br><br>Fuzzy inferencing is
a kind of approximate reasoning in which
inferencing is done based upon<br>imprecise
conditions/specifications and imprecise data and is
deterministic.<br><br>Is it legitimate? Depends on your definition of
legitimacy. If you own a Saturn automobile with and automatic
transmission, you better hope its<br>legitimate. Same with high
end Fords.<br>Foreign auto manufactures are very fond
(and very<br>quiet) about using FL in their ABS, fuel
injection, engine management, etc. systems (e.g.<br>BMW, and
most Japanese manufacturers). Would you<br>buy a car
that uses something "fuzzy" in the<br>braking system
or shifting gears for you? Probably not.<br><br>Why
they don't tell you should be obvious.<br><br>Why do
they do it?<br><br>Because they can get a good,
reasonably accurate<br>approximate result in a short amount
of time from<br>imprecise data, imprecise control
specifications,<br>and that is computationally<br>efficient, robust, and
flexible to reprogram via<br>ROM/FPGA based uprocessor
controllers.<br><br>IMHO, fuzzy logic is a "stealth" technology that <br>is
used more pervasively than most people
are<br>aware.<br><br>There are several other benefits to using fuzzy logic
that I'll leave for the interested person<br>to
discover for themselves.<br><br>It may be of interest to
some that the FLAKEY<br>autonomous robot project at
SRI used fuzzy logic<br>extensively to "blend"
multiple behaviours into<br>final multiple, concurrent
actions.
