METHOD OF AND APPARATUS FOR EVALUATING MEMBERSHIP FUNCTIONS OR RULES IN FUZZY REASONING SYSTEM

摘要

For an input value, conformity grades are computedand are displayed for established membership functions. Alternatively,conformity grades and change rates thereof developed when afuzzy reasoning system is operated are displayed.Alternatively, a change with respect to time of the inputvalue is displayed to be superimposed onto a tablerepresenting the established rules. Alternatively, an output valueresultant from a fuzzy reasoning conducted with a particularrule removed is compared with a fuzzy reasoning achieved byusing all rules, thereby displaying the difference on arule table. As above, various features in the fuzzyreasoning are extracted and are displayed so as to checkadequacy of the established membership functions and rules.
