Remarks
In fuzzy logic, the confidence in a conclusion is equal to the confidence in one of the precedent facts. In a fuzzy OR, the confidence in the conclusion is the maximum value of its precedent facts. In a fuzzy AND, the confidence is the minimum.For instance, a car’s desirability might be caused by it being great fun to drive OR having great gas mileage. If a car had a 0.4 grade for funToDrive but greatMileage of 0.8, the carDesirability would be set to 0.8 — the maximum of its precedents. funToDrive, in turn, might require power AND handling. So a car with plentyOfHorsepower of 1.0 but goodHandling of 0.4 would end up with a funToDrive grade of 0.4 — the minimum of its precedents.
