Fuzzy Logic on Arduino board

I have a question about how to convert files (.Fis) to Arduino code.
The website (http://www.makeproto.com/) doesn't work, I don't know why.
if there is another way to implement fuzzy logic in the arduino board, please tell me
Thanks to all of you.

isn't fuzzy logic simply the product of the sub-ranges of of wo or more variables scaled from 0-1.0 compared to some threshold (e.g. 0.9)?

may be something to look at here ? (that's the same thing but you run it yourself)
