Abstract: The invention relates to a codifying and storing method for membership functions (MF) representing a membership degree (α) of fuzzy variables (x) defined within a universe of discourse (U.d.D.) which is discretized into a finite number of points (n). The membership functions (MF) are quantized into a finite number of levels (p) corresponding to a finite number of membership degrees, and are stored by means of a characteristic value of each sub-set of values of fuzzy variables (x) having for their image the same value of the membership degree (α) corresponding to one of said levels.
The invention further relates to a method for calculating the value of the membership degree of a fuzzy variable defined within a universe of discourse (U.d.D.) discretized into a finite number of points (n) with reference to a membership function (MF) thereof, as well as to a circuit (10) for calculating the membership degree (α) of a fuzzy variable (x) with reference to a membership function (MF) thereof.
