The TOPSIS method is a static comprehensive evaluation method for wide range applications. However, it encounters the reverse order problem in practical applications. Moreover, its evaluation value Ci only reflects the relative proximity of each evaluation object inside but not to the degree of closeness to the ideal optimal solution. The evaluation value is also limited to distinguish between the ranges of merit ranking. Since TOPSIS method has the wide range of applications, it is necessary to overcome the drawbacks of TOPSIS method. This article proposes a new improved TOPSIS method, which shows strict isotonicity and is more sensitive than the traditional TOPSIS method. The medical application based on this improved TOPSIS method is introduced.
