TOPSIS dataset provides a structured representation of criteria, performance scores, weightages, and other relevant information necessary for the TOPSIS method to facilitate decision-making.
TOPSIS calculates the similarity scores for each alternative based on its proximity to the ideal and anti-ideal solutions. The similarity scores are then used to rank the alternatives.
The alternatives are ranked based on their similarity scores. The one with the highest similarity score is considered the most favorable and is chosen as the best alternative.
