This work is devoted to the modeling of the fuzzy assessment of the impact of human factors in emergency situations in industrial activity. Relevance of the research lies in the uncertainty, heterogeneity and uncertainties of the input data, on the basis of which it is necessary to assess the impact of human factors in emergency situations. The article describes the main stages of the fuzzy modeling: fuzzification of input data, the construction of inference rules and defuzzification of the output variable. The proposed base of fuzzy inference rules include input linguistic variables, fuzzy rule-production and output linguistic variable. The constructed model allows us to estimate the degree of influence of the human factor in the conditions of uncertainty and subjectivity.

The effect of sodium chloride concentration on the job ORTA electrodes. It is found that the electrodes OPTA, especially in the sodium chloride concentration below 50 g/liter, three groups occur conjugate processes, oxidation of chloride ions, the solid-phase oxidation of the anode material, dissolution of the active catalytic coating. The processes of oxidation of chloride ions prevail in current densities of 0.001 - 0.032 A/cm2 at high current densities become essential processes of oxidation of the ruthenium oxide coating. The oxidation of chloride ions, especially at concentrations less than 50 g/liter can be described as occurring in a constantly evolving anode active material due to its corrosion and solid-phase oxidation.

We consider a class of complex systems, such as socio-technical systems on the example of the elemental sulfur producing by Claus process. Its operation takes place in different types of uncertainty and requires the development of specific approaches to the analysis and evaluation of many factors that affect the system operation and aren't giving in to the quantitative and qualitative description. The paper formulates the problem of multifactor risk analysis of emergency situations at hazardous production facilities using the methods of system analysis. The main groups of factors, parameters, and communication of human operator with the technical subsystem are identified. A method is proposed for assessing the level of selected factors influence on the emergency situations risk in system. Introduced the terminological basis for constructing patterns of socio-technical systems state indicators. According to the expert survey an example of the impact assessment diagram of each parameter to the "weight" of one of the indicators was made.

Discusses the use of complicated UWB signals in supergrades and subsurface radiolocation. The aim of this work is to analyze the possibility of complex UWB signals using a simpler aproximarse signals, which greatly simplifies the task of finding the basic parameters of the echo signal. As a model of the complex signal of the selected signal with linear frequency modulation. Designed the error of approximation of ultra-wideband LFM echo signal of the echo signal with a rectangular spectrum with different environment settings and the coefficients of the high bandwidth. Based on these data it is concluded that at high modulation indices it is possible to replace the analytical calculations of complex expressions for the spectrum of the chirp signal by a simple ratio aproximarse spectrum.
