How we score

TOPSIS compares every alternative to the best and worst possible outcomes, then ranks by relative closeness. The output includes each score and final rank.

Normalized criteria

Each criterion is scaled to neutralize unit bias.

Weighted priorities

Weights shift the ranking toward what matters most.

Scores are converted to an ordered list automatically.
