| Resumé≠ | DEFUZZ-ALPHA-CUT (Alpha-Cut Defuzzification — Crisp interval or representative via α-level cut) is a defuzzification multi-criteria decision-making (MCDM) method introduced by Zadeh, L.A. in 1965; 1985. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result. | FUZZY-TOPSIS (Fuzzy TOPSIS (Chen-Hwang 1992) — Trapezoidal fuzzy TOPSIS with Zadeh sup-min similarity distance) is a ranking multi-criteria decision-making (MCDM) method introduced by Chen, S.-J., Hwang, C.-L. in 1992. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result. |
