Clusters, criteria and calibration-A reply to Hauser and Peniwati

Hauser and Peniwati have critized papers by the authors on the grounds that (1) clusters are not criteria and (2) transformable multiple-criteria problems are really single-criterion problems. They claim that the axiom of independence only applies to criteria. Although in agreement with several of their statements, the authors point out that the axiom applies to levels and that criteria priorities must perform a calibration (scaling) function if composite ratio results are to be achieved.
