研究了二值命题逻辑中模糊推理的全蕴涵α-三Ⅰ算法的形式化问题.提出了(F(S),)中的极小α公式的概念,当α∈{k/2n|k=0,1,…,2n,n=1,2,…}时得到如下结果:(1)全体极小α(α{0,1})公式构成(F(S),)中的反链;(2)当α=1时,全体极小α公式之集是相容的;当α≠1时,全体极小α公式之集是不相容的.证明了广义MP问题的形式化α-三Ⅰ解的存在性定理.
The aim of to study the formalized theory of α-triple Ⅰ methods for fuzzy reasoning in classical propositional logic.The concept of minimal α formula in(F(S),) is introduced and the following results are proved when α belongs to k/2n|k=0,1,…,2n,n=1,2,…:(1) All the minimal α(α{0,1}) formulas constitute an antichain in(F(S),);(2) The set of all the minimal α formulas is consistent when α equals 1;otherwise,it is inconsistent.The existence theorem of formalized α-triple Ⅰ solution for problems of generalized modus ponens is also proved.
