Is anybody on the network interested in fuzzy logic? Is there already a group to discuss this area? If not, how about starting one? I do not know the procedures to start a new group, so will somebody out there get in touch with me. Sanjiv

If there is one, I'm ignorant of it (someone please inform). I recently posted a reply to someone on this subject. Is there a more general interest?

I am a junior in Computer Engineering and very interested in knowing more about fuzzy logic. Could anyone out there suggests some suitable books or articles to me? Thanks very much. Yin

I am an Honours student at the University of Tasmania currently writing an essay on Fuzzy Logic and its applications to production systems. The recent stream of postings on Fuzzy Logic has been most helpful, especially the references, so thank you for posting. One article that was refered to by Giovanni Moretti (G.Moretti@massey.ac.nz) was "Designing with Fuzzy Logic" by Kevin Self (IEEE Spectrum, Nov 1990, pp42-44,105). This is a short, chatty, interesting article which explains mainly about Fuzzy Control Systems. One statement in this article was : Fuzzy logic is a misnomer. Developed by Lotfi A. Zadeh of the Univeristy of California at Berkley, it is firmly grounded in mathematical theory. Combining multivalued logic, probability theory, artificial intelligence (AI), and neural networks, it is a digital control methodology that simulates human thinking by incorporating the imprecision inherent in all physical systems. The problem I have with this statement is its accuracy. My understanding of Fuzzy Logic leads me to believe that probability theory is not combined within Fuzzy Logic, though closely related. Fuzzy Logic does not contain any concept of randomness that probability does. Further, AI and neural networks are not requirements of Fuzzy Logic, and it is not only a method of digital control. This is probably being very pedantic, but I am finding that many articles have confused me. Am I correct in assuming that Fuzzy Logic and Fuzzy Set Theory are independant of AI and NN? I was wondering was how much of current research is really relevant to any form of application ( after seeing an article on Fuzzy Sets and Aristotlian semigroups )? What is the purpose of all this work? How much could be described as being a firm basis for use within production systems?

Fuzzy logic is the popular name for what is probably better called continuous logic, as opposed to bivalent logic. For references, look for papers and books by Zadeh, Klir & Kosko.

WRONG. Fuzzy Logic may be considered to belong to the class of continuous logics but it is certainly not a generic (let alone a popular) name for non-bivalent logics. However, it is true that Fuzzy Logic is popular. People like fuzzy things. -wido.
