TOPSIS

TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) is a decision-making method that helps choose the best option from several alternatives. It works by identifying an ideal solution (best possible) and a worst solution (least desirable). Each option is evaluated based on how close it is to the ideal and how far from the worst. The option closest to the ideal and farthest from the worst is considered the best choice. TOPSIS provides a clear, quantitative way to compare options based on multiple criteria, making complex decisions more objective and manageable.
