Method of and apparatus for evaluating membership functions or rules in fuzzy reasoning system

摘要

For an input value, conformity grades are computed and are displayed for established membership functions. Alternatively, conformity grades and change rates thereof developed when a fuzzy reasoning system is operated are displayed. Alternatively, a change with respect to time of the input value is displayed to be superimposed onto a table representing the established rules. Alternatively, an output value resultant from a fuzzy reasoning conducted with a particular rule removed is compared with a fuzzy reasoning achieved by using all rules, thereby displaying the difference on a rule table. As above, various features in the fuzzy reasoning are extracted and are displayed so as to check adequacy of the established membership functions and rules.
