Abstract
There is system analysis and information security risks assessment based on processing of linguistic variables. These variables are based on standard parametric trapezoidal fuzzy numbers with a fixed number of term sets. These standards are defined by experts at the initialization stage of basic units in the course of system setup. Its efficient use will increase, if there is a possibility of standards correction without the corresponding experts' involvement. To solve this problem, the implementation method of function transformation of linguistic variables standards based on a single increment number of terms using expert assessments made at the stage of system settings is proposed. This will simplify the procedure of standards adjustment, through the process of a single increment number of terms for trapezoidal fuzzy numbers.
