ABSTRACT:
An apparatus for processing fuzzy information based on a membership function defining a fuzzy set, which generates the membership function with an elliptic, parabolic or rectangular, shape of equi-grade contour plane or line, incorporates the membership function at any position in a multi-dimensional space with a plurality of input variables and grade of compatibility as coordinates, and calculates and outputs a value of the grade of compatibility with respect to the incorporated membership function for given input variables.
