Summary: Allen’s interval algebra allows one to formulate problems that are, in the general case, intractable; for this reason several tractable sub-algebras have been proposed. In this paper the attention is focused on the fuzzy counterparts of those sub-algebras and a different method to identify their relations is shown: rules for identifying fuzzy tractable relations starting from the knowledge of the classic tractable relations. Enumeration is used to verify the rules and quantify expressiveness, and algebraic considerations adopted to bind the enumeration itself.
