Techniques for Order of Preference by Similarity to Ideal Solution (TOPSIS)

TOPSIS is a decision-making method that helps compare options based on multiple criteria. It identifies the best choice by measuring how close each option is to an ideal solution—perfect scores across all criteria—and how far it is from the worst-case scenario. The option most near the ideal and far from the worst is considered the best. Essentially, TOPSIS ranks choices by analyzing their strengths and weaknesses relative to ideal standards, providing a clear, quantitative way to make complex decisions systematically.
