Abstract:		In this paper, the AHP, a multi-criteria decision method designed to solve hierarchically structured problems, is discussed. Two of its main procedures are reviewed in detail: pairwise comparisons that allow transformation of values measured on a physical scale into dimensionless numbers and derivation of weights and additive aggregation used to synthetize priorities. Drawbacks of the procedures are shown and substantiated, variants of their optimization and elimination are suggested. In order to conduct sensitivity analysis, visualization methods are used. These methods permit the comparing of alternatives taking into account possible uncertainties, generate scenarios of possible rankings of decision alternatives under different conditions and assess the impact of changes of criteria weights on the result. In this case, the visualization serves as an argumentation base for the final decision, it allows to analyze a huge amount of tabular data within a limited amount of time.
