Ways to evaluate fuzzy predicates

Hi,

I was wondering what systems people use to evaluate fuzzy predicates. I
have seen definitions such as:

A AND B=min(A,B)
A OR B=max(A,B)

and am wondering what alternative definitions exist. Are there any means
of assigning different weights to A and B, for example? Can fuzzy
implication be dealt with in analogous terms to normal Boolean
implication? i.e. does this hold:

A->B == NOT(A) OR B == max(1-A,B)

Cheers,
Frank O'Dwyer.
