A Kind of Approximate Reasoning Principles

In this peper, we reseach the following form of approximate reasoning.Ant 1: (If x1 is A1 and x2 is A2and… and xn is An then y is B) is t1.Ant 2: (x1 is A’1 and x2 is A’2 and… and xn is A’n) is t2.Cons: (y is。B’) is ts.First we put forward two reasonable approximate reasoning principles, then, accordingg tO the two reasoning principles we construct a new kind of approximate reasoning methods. The bole idea which the new kind of approximate reasoning methods is that according to the strength p(A1(x1), …, An(xn) )→B (y) which A1(x1),…, An(xn) implicate B(y) and the degree of A’(x) approximates to A(x), we determine the upper limit and B’(y), then take a definite value B’(y) in between the upper limit and the lower limit, and make the reasoning method satisfied the two reasoning principles.
