Re: probability vs. fuzziness

Dear colleagues,

I have read various messages to fuzzy mail. I work more on
the mathematical basis of fuzzy logic, modeling of linguistic
meaning, and also fuzzy control. I am somewhat surprized by some
standpoints. They often come, in my oppinion, from misunderstanding
the core of fuzzy logic. It is evident that the latter deals with
other phenomenon than probability: probability deals with uncertainty
(occurrence of events) while fuzzy logic with vagueness (delineation
of properties). Hence, incorrect application might lead to
misunderstandings. I do not deny that various applications of
probability theory may be better - fuzzy logic is not a panacea.
But I am strongly convinced that reasonable combination of both
approaches is the right way - simply because then we can manage the
whole phenomenon we meet - the undeterminateness. Either probability
or fuzzy logic deals with only one of its part and thus, it can hardly
be sufficient. And quarels, which part is more important and useful,
are baren.

I challenge you all, doubters: come to IFSA'97 Prague, June 25-
29, 1997 with your criticism. We can have a very nice discussion.
