For a comparison of different methods, see for example How to derive priorities in AHP: a comparative study, by Alessio Ishizaka and Markus Lusti, as available here: http://eprints.port.ac.uk/9041/1/filetodownload,70633,en.pdf

The AHP preference matrix
if the AHP consistency ratio is larger than this value, AHP is not applied and equal weights are returned.
