The Technique For Order of Preference by Similarity to Ideal Solution (TOPSIS)

Abstract

The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is the part of the analytical multi-criteria decision-making technique. The main idea of this technique, the preferred alternative is the one with the most close to the positive ideal solution and the further to the negative ideal solution. The positive ideal solution is formed as a combination of the best points of each criterion. The negative ideal solution is a combination of the worst points of each criterion. This technique is only can be applied for the numerical dataset where the importance weights of the criterion known or defined based on the experts opinion numerically. And the ranking results can be obtained corresponding the importance weights of the defined criteria. In this study the detailed information about this technique will be presented.
