Abstract

A data processing system for testing a rulebase implemented in a rule evaluation process utilized for transforming fuzzy inputs to fuzzy outputs in a fuzzy logic operation, the rule evaluation process including a plurality of rules, wherein a path in the fuzzy logic operation includes one of the fuzzy inputs specified by the path, one of the plurality of rules specified by the path, and one of the fuzzy outputs specified by the path, wherein the rule evaluation process implements a MIN/MAX method of rule evaluation. The system determines which paths in the fuzzy logic operation can be tested simultaneously, and assigns values to test vectors in order to test the paths in a manner consistent with the determination of which paths in the fuzzy logic operation can be tested simultaneously, wherein paths that can be tested simultaneously can be tested by a same test vector.
