The known information security assessment risk system (developed by authors) is based on processing methods of linguis-tic variables. These variables are based on the standard parametric trapezoidal fuzzy numbers with a fixed number of term sets. Eta-lons are defined by experts at the stage of base units initialization during setting-up system. Efficiency of its use would increase if it is available to correct etalons without the involvement of appropriate experts. To solve this problem authors propose a method of function realization for linguistic variables etalons transformation based on a single incrementation the terms number using expert estimates made during system setting-up. This will simplify the procedure for correcting etalons, by implementing a single process incrementation the number of terms for trapezoidal fuzzy numbers.
