ABSTRACT:
A fuzzy inference apparatus and corresponding method which uses a plurality of rules to realize a fuzzy inference conclusion. The apparatus includes a first component which represents the rules as geometric shapes. A second component determines an area and center of gravity position of each of a number of the geometric shapes, each corresponding to one of the rules. A third component of the apparatus determines the fuzzy inference conclusion in accordance with a mathematical summation of a product of the area and center of gravity of each of the geometric shapes, divided by a summation of the center of gravity of each of the geometric shapes. The third component could further determine the fuzzy inference conclusion based on the significance of the rules, as well as the center of gravities and areas of the geometric shapes representing the rules.
