A revised framework for deriving preference values from pairwise comparison matrices

In a recent study, Choo and Wedley proposed a framework to categorize and conduct simulations to compare methods for deriving preference values from pairwise comparison matrices. This study demonstrates that some pairs in the examined methods are identical and some methods can be solved in better ways. Additionally, the simulations of Choo and Wedley are somewhat idealized. Thus, this study provides additional simulations. The simulation results lead to different method ranking and conclusions from those of Choo and Wedley.
