Methods for making group decisions – Promethee GDSS and AHP

Summary/Abstract: Making a “good” decision requires considering many decisive variants. Different decision makers may evaluate the variants and criteria in different ways, hence a multicriterial decision cannot be recognized as fully detached. One way to make such an evaluation significantly more objective is to take advantage of a group of experts instead of only one expert. In this work, the AHP and Promethee GDSS methods were applied for group evaluation. GAIA analysis was performed to evaluate the “accuracy” of the obtained decision and to point out the ways of its possible improvement.
