Comparative Analysis of a Novel M-TOPSIS Method and TOPSIS

Abstract

In this study, we introduce a novel modified synthetic evaluation method (M-TOPSIS) based on the concept of original TOPSIS and calculate the distance between the alternatives and ‘optimized ideal reference point’ in the D⁺D⁻-plane. It could avoid rank reversals and solve the problem on evaluation failure that often occurs in original TOPSIS, so we believe that the mechanism of M-TOPSIS is more reasonable. Furthermore, the M-TOPSIS method is simple in both concept and calculation procedures.
