摘　　要：A novel fuzzy decision-making technique concerning two kinds of uncertainty is intro-duced. It uses a similarity measure of fuzzy sets and threshold λ to determine whether arule should be fired and a modification function (MF) is used to modify the deduced con-sequent. The strength of confirmation (SC) of every production rule, which is given by ex-perts, is distinctive and is used to modify the consequent once more. It provides a more effi-cient tool for the building of some Expert Systems. Finally, an efficient algorithm is pro-posed and numerical examples are presented.A novel fuzzy decision-making technique concerning two kinds of uncertainty is intro-duced.
