Comparison of the REMBRANDT system with analytic hierarchy process

This study compared the use of the REMBRANDT system with analytic hierarchy process (AHP) in a group multiple criteria selection problem. The decision was to select an operations management text, and the decision was the responsibility of a faculty group. The primary purpose of this study is to apply REMBRANDT to the same problem that was supported by AHP. There are no noticeable differences between the techniques from the perspective of the users, as the same input is used. Important technical differences between AHP and REMBRANDT are demonstrated, including (1) different ratio input scales, (2) alternative calculation of impact scores, and (3) a different aggregation procedure. REMBRANDT was found to recommend the same decision as AHP when the geometric mean was used for aggregation, but a different decision was given by conventional AHP using arithmetic mean aggregation.
