Abstract

In the performance of an information security risks analy-sis and assessment task in weakly formalized environment mostly necessary to perform data processing in fuzzy conditions. For this process realization are used systems, in which the evaluation is based on the linguistic variables, which are based on parametric triangular fuzzy numbers etalons with a given number of terms. Etalons are deter-mined by expert’s at basic unit’s initialization stage during configuration of such systems. As a basis the expert takes ranges of values, that based on his conclusions, converts into fuzzy numbers. Efficiency of those evaluation systems will increase, if will be stipulated the opportunity of auto-matic intervals transformation without the involvement of appropriate expert’s. In this study proposed appropriate conversion method to solve such problem. It will simplify the etalons formation procedure, by implementing process of intervals transformation in triangular fuzzy numbers and minimizes impact of human factor.
