| Criterion | Fuzzy Weight (l, m, u) | Crisp Weight | Rank | | :--- | :--- | :--- | :--- | | Cost | (0.32, 0.41, 0.53) | 0.42 | 1 | | Security | (0.21, 0.28, 0.36) | 0.28 | 2 | | Scalability | (0.15, 0.18, 0.22) | 0.18 | 3 | | Support | (0.08, 0.13, 0.19) | 0.12 | 4 |

A well-constructed is a cost-effective, transparent tool for researchers and practitioners to handle uncertain multi-criteria decisions without specialized software. While Excel has limitations, a careful implementation following the geometric mean + CoA defuzzification method yields reliable rankings. Users are strongly advised to validate the template against benchmark problems before real-world application.

The final sheet multiplies Criteria Weights by Alternative Scores to produce a final ranking (e.g., Supplier A = 0.52, Supplier B = 0.31, Supplier C = 0.17).

: If your decision has many criteria (e.g., 10+), the number of pairwise comparisons grows exponentially. Without a clean UI, the spreadsheet can become a "wall of numbers."
