Ranking the Alternatives With a Modified TOPSIS Method in Multiple Attribute Decision Making Problems

In this article, we present a method for ranking alternatives in multiple attribute decision making (MADM) and group MADM problems. Our method first determines the importance of separations of each decision from positive ideal solution and negative ideal solution and then computes the relative closeness of each alternative. The alternatives are ranked based on relative closeness. The method is illustrated using three examples and the results are compared with other methods.
