A considerable usage increase of multicriteria methods is recently observed in the area of quantitative analysis of social or economical phenomena. The PROMETHEE methods are discerned from other multi-criteria methods by depth of their intrinsic logic and by using preference functions, which make up a foundation of the methods. Shapes of functions and their parameters are chosen by decision-makers thus exerting clear advantages and features of the methods. This paper reveals influence of the choice of preference functions and their parameters on the outcome of evaluation. Along with already recently described by the authors PROMETHEE I method the other PROMETHEE II method is described and examples of its application are provided. New types of preference functions were proposed.
