ABSTRACT:
In the antecedents of a group of fuzzy reasoning rules, a proposition x1=PL which appears the most frequently is extracted, and one group consisting of Rules 1, 2, 6, 8, 9 which contain this proposition is formed. Rule 8, in which only the proposition x1=PL is contained in its antecedent, is placed at the beginning of an array of rules. In the Rules 1, 2, 6, 9 which remain, a proposition x2=PM which appears the next most frequently is extracted, and a sub-group consisting of Rules 1, 6, 9 which contain this proposition is formed. The rules of this sub-group are arranged in a fixed order following the Rule 8. The remaining Rule 2 is placed next in the array. Processing is performed in similar fashion with regard to other Rules 3, 4, 5, 7, 10. By thus rearranging rules in accordance with a sequence which includes propositions having a high frequency of appearance, redundant processing regarding redundant propositions is eliminated and processing is made more efficient.
