Understand MCDM methodology from first principles. Choose a path that matches your experience level.

What is a credible decision route?

How do I defend the result?

Which assumptions shaped the route?

Key concepts

Weighting: Assigning relative importance to criteria. Methods: AHP, Entropy, CRITIC, BWM.
Normalization: Scaling criteria to a common unit. Types: min-max, vector, linear, sum.
Robustness: Stability of rankings under parameter changes. Tests: sensitivity, rank reversal.
Aggregation: Combining multiple method rankings into consensus. Methods: Borda, Copeland, Schulze.
Outranking: Pairwise comparison of alternatives without full compensability. E.g., ELECTRE, PROMETHEE.
Ideal solution: Best possible values per criterion. Distance from ideal determines ranking. E.g., TOPSIS.

30 methods

TOPSIS, VIKOR, ELECTRE, PROMETHEE, EDAS, CODAS

25 methods

30 methods
