Abstract
Abstract This invention relates to the methods and devices mentioned in the title, where an investigation is performed to see if an identity is found among the set membership functions, different numbers are allocated to the membership functions that are different from each other, the same number is allocated to the membership functions that have the identity, and stores these membership functions in association with their numbers, labels and names of their input/output variables.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
An apparatus for setting membership functions, which comprises: means for checking whether there is identity among membership functions set for each input and output variable and for each identification code; means for assigning different numbers to different set membership functions and identical numbers to set membership functions possessing identity; first memory means for storing data, which represents a set membership function, in correspondence with the number assigned thereto; and second memory means for correlating and storing the numbers assigned to the membership functions, the identification codes of the membership functions which correspond to these numbers, and names of the input or output variables.
Claim 2
Dependent Claim
30 words
An apparatus for setting membership functions according to claim 1, wherein said identification codes of the membership functions are items of linguistic information representing characterizing features of the membership functions.
Claim 3
Dependent Claim
63 words
An apparatus for setting membership functions according to claim 1, further comprising means for forming membership functions of a standard shape for each of the input and output variables in dependence upon the number of types of membership functions set on a positive side of the variables and the number of types of membership functions set on a negative side of the variables.
Claim 4
Independent Claim
97 words
A method of setting membership functions, which comprises: checking whether there is identity among membership functions set for each input and output variable and for each identification code; assigning different numbers to different set membership functions and identical numbers to membership functions possessing identity; storing, in first memory means, data representing a set membership function in correspondence with the number assigned thereto; and correlating and storing, in second memory means, the numbers assigned to the membership functions, the identification codes of the membership functions which correspond to these numbers, and names of the input or output variables.
Claim 5
Independent Claim
46 words
An apparatus for analyzing membership functions comprising: means for calculating degree of resemblance between two membership functions by correlating membership functions; and means for comparing the calculated degree of resemblance with a predetermined reference value and outputting at least membership functions judged to resemble each other.
Claim 6
Independent Claim
43 words
A method of analyzing membership functions, which comprises: calculating degree of resemblance between two membership functions by correlating membership functions; and comparing the calculated degree of resemblance with a predetermined reference value and outputting at leapt membership functions judged to resemble each other.
