Gradual rules represent constraints restricting outputs of a fuzzy system for each input. They are tailored for inter- polative reasoning. Our approach to inference is founded on the use of well-conditioned fuzzy systems. It is based on the computation of the fuzzy output under an interval- valued input. A double decomposition of fuzzy inputs is done in terms of partitioning in order to infer locally and in terms of -cuts to simplify the fuzzy input.Cet article propose une méthode générique d'inféren...
