What is defuzzification?

Defuzzification is the process of converting a fuzzy set into a crisp value, typically used in fuzzy logic systems. It involves selecting a single representative value from the fuzzy output set, enabling practical decision-making or control actions. Common methods of defuzzification include the centroid method, which calculates the center of gravity of the fuzzy set, and the maximum method, which selects the highest membership value. This step is crucial for translating the imprecise, qualitative information from fuzzy logic into precise, quantitative results.
