: Convert the TFN weight back to a single "crisp" number using the Center of Area method: Normalization : Ensure all final weights sum to Validation: Consistency Ratio (CR) fuzzy ahp excel template
Fuzzy AHP solves this by replacing crisp numbers with . A TFN represents a range of probabilities using three values: Lower bound ( ) : The minimum possible value. Prominent/Middle value ( | Feature | Standard AHP | Fuzzy AHP

The template applies a defuzzification formula – for instance, ( \textCrisp weight = \fracl + 2m + u4 ) (a common centroid method). It then normalizes the weights so that they sum to 100%.
