Technique for Order Preference by Similarity (TOPSIS) have been developed. The TOPSIS method also been developed using intuitionistic fuzzy set. The existing method use the Eucledean distance, but in this article we use the new formula. This formula different from the existing method. It is comparable and more transparent with the measure proposed earlier. This formula is used to calculate distance for each alternative according to the positive-ideal solution and negative-ideal solution. Clearly this is different from existing CIF-TOPSIS methods. We explain the method step by step. Finally, we presented the illustrative example of this method to select a new hospital location. © 2025, Diogenes Co. Ltd.. All rights reserved.
