Scoring and Ranking Each Alternative

Performance Trade-off uses a combination of requirements and weights to score each alternative and, thus, to rank the alternatives relative to each other.

Performance Trade-off scores and ranks each alternative based on a combination of the thresholds and objective assigned to the parameter along with the weight assigned to the parameter and the ranking method. Alternatives in the data table are sorted by rank, which is inversely related to the score—the alternative with the highest score is given a rank of one.

Performance Trade-off uses the weighted sum ranking algorithm to compute the scoring and ranking. See The Weighted Sum Ranking Algorithm for more details.
