RESTORATION OF A MODEL OF A DYNAMIC NONLINEAR SYSTEM FROM THE TIME SERIES GENERATED BY IT
Description
The main task in the analysis of time series is the reconstruction of the dynamical system that generated this series. To illustrate the nature of the behavior of a dynamic system described by a nonstationary time series, a «phase portrait» method is proposed. An acceptable description of the phase space of a dynamical system can be obtained if we take instead of real variables of the system delay vectors composed of the values of the series at consecutive moments of time. Restoration in a given class of a system of differential or difference equations is performed based on the scalar time series of the observed process. In order to eliminate the measurement error and accurately represent the position of the object in the current, future, or any of the past moments, it is proposed to apply the Kalman filter using the known mathematical model of object dynamics

Description
The article describes a development of the mathematical model for managing access rights affecting the assessment of the effectiveness of the integrated systems of protection with selection factors, as well as groups of factors affecting the system security policy. The model works due to forming a binary expression which would lead to either a zero value or the unit, or not significant value. Next, we have control comparisons and analysis of the values that provides an expert decision about blocking the access rights or not. This system is adaptive and able to evolve by adding various factors and expansion of expert decisions
