function of an accessory
matrix of preferences
For use in models of decision-making of the information formalized on the basis of the theory of fuzzy sets, procedures of construction of corresponding functions of an accessory are necessary. From that the how much adequately constructed function reflects knowledge of the expert or experts quality of accepted decisions depends. Matching standard forms of functions of an accessory (triangular, Gaussian and bell-shaped) on expert data that are set by tabu-lated way as association of one-dot sets, or on the basis of a matrix of preferences is lead.
