5.3 Comparison with Traditional Ranking Methods
In order to verify the similarity as well as the discrepancy between different
ranking methods, the CPWR DRAPE rankings are compared to those obtained from
the following traditional ranking techniques: dominance functions (DOM), simple
average ranking (SAR) and utility functions (UTI).
As an example, the rankings for all the considered methods were applied to
American countries and the comparisons are reported in Fig.7a when equal weights
are given to all the criteria and in Fig.7b when proportional weights are given to the
criteria.
