ABSTRACT:
An optimized method of computing the value of the degree of membership of a fuzzy variable defined within a universe of discourse that is discreted into a finite number of points by way of a membership function thereof, wherein the membership function is quantified into a finite number of levels corresponding to a finite number of degrees of truth, and is stored as a characteristic value of each subset of fuzzy variable values being all mirrored in one value of said degree of membership corresponding to one of said levels. The computing method includes generating a binary sequence; generating an address signal from the bits in the binary sequence; reading the contents of the memory storing the membership functions at each address signal to obtain a characteristic value; and comparing the characteristic value with the value of a fuzzy input variable. These steps are repeated until a characteristic value is found that is equal to or greater than the value of the fuzzy input variable, the degree of membership sought being correlated with the address value of the characteristic value.
