Multi-criteria evaluation of complex phenomena is an important part of decision problems. The multi-criteria evaluations are different types of difficulties, in particular, the multiplicity and diversity of the assessed phenomena, the multiplicity and the variety of diagnostic variables characterizing the evaluated phenomenon, the difficulty to transform the quality characteristics of quantitative traits, the difficulty of aggregating subcriteria. This paper presents selected models of multi-criteria evaluation corresponding to different decision-making situations. These models will be applied in the system supporting management in the area of knowledge management in mechanical engineering industry enterprises.
