COMBINING PROMETHEE AND AHP: MATCHING THE MEANING OF WEIGHTS

No specific guidelines are provided on how to determine weights in multi-criteria decision analyses with PROMETHEE. Among other weighting methods, the AHP has been proposed as a tool to support the elicitation of weights. However, little attention has been paid to the meaning of the weights derived, and the match of these weights with the model requirements of PROMETHEE. We discuss the diversity in meaning of weights in multi-criteria decision analysis, and proposed recommendations to prevent possible mismatches when combining AHP with PROMETHEE.
