In a fuzzy inference system using a plurality of output label membership functions mBi(y), each of which is represented by a singleton having a position yi and a consequent grade gi, a defuzzifying method comprising the steps of: selecting and identifying n singletons in magnitude order of the consequent grade as g1, g2, . . . , gn (g1 is the highest); and obtaining the center of gravity y0 as the final result of defuzzification, by calculating the following approximate equation (n=2, 3, . . . )y0 APPROX y1+g2 (y2-y1)+g3 (y3-y1)+. . .+gn(yn-y1).
