In this paper, we study the tractability of the Fuzzy Temporal Qualitative Algebra QAf uz . To this aim, we extend to the fuzzy framework the study presented in [7] where all tractable fragments of the Qualitative Algebra are identified. We don’t directly extend classical proofs to our fuzzy framework, but we generalize the results obtained in the classical case exploiting the notion of α-cut in relating the QAfuz to its classical counterpart QA.

Abstract
In this paper, we study the tractability of the Fuzzy Temporal Qualitative Algebra QAf uz . To this aim, we extend to the fuzzy framework the study presented in [7] where all tractable fragments of the Qualitative Algebra are identified. We don’t directly extend classical proofs to our fuzzy framework, but we generalize the results obtained in the classical case exploiting the notion of α-cut in relating the QAfuz to its classical counterpart QA.
