TOPSISEvery run follows the same five-step pipeline — transparent, reproducible, auditable.
Upload or paste your decision matrix. 23+ family formats auto-detected.
Min-max, vector, or linear-sum normalization — direction-aware for benefit vs cost criteria.
Subjective (AHP, BWM, SWARA) or objective (Entropy, CRITIC, NMD). Quintet of alternatives shown.
Primary method (TOPSIS, VIKOR, ELECTRE, PROMETHEE) + 4 alternatives for cross-validation.
Weight perturbation, method cross-agreement, rank reversal detection. Defensibility score.
Answer three questions and we'll surface three MCDM methods that match your data profile.
Alternative count drives whether pairwise outranking stays tractable.
