   Carmel,   
      
   Fuzz-C does this.   
      
   If  (A is a and B is b) or (C is c) then D is d   
      
   The Degree of Membership is calculated for   
    (A is a and B is b) or (C is c) by   
      
   getting the DOM for  A is a   
   combining it with  DOM B is b with a "fuzzy and" then   
   use a "fuzzy-or" to combine the DOM for C is c.   
      
   The resulting DOM is used in evaluating the consequence of D is d   
      
      
   Fuzzy hedges are primarily shape changes to the 0..1 and 1..0 fuzzy functions.   
      
   and is often implemented as function modifying a DOM   
      
   ie   
      
   DOM = very(A is a) ;   
      
   or   
      
   DOM = about (A is a);   
      
   There is some online material here
