Air pollution in residential areas near industrial plants is one of the most significant problems of modern ecology. The resulting dust is one of the important factors in assessing the adverse impact on the environment. Studies show that the greatest danger to the human body is particles up to 10 microns in size. When analyzing the dispersion of dust in the residential and industrial areas, it is possible to estimate the percentage of particles PM10 and PM2.5 from the total amount that is necessary to effectively control the effects of dust on human health. The article gives a comparative analysis of the results of studies of the dispersion composition and dust concentration in the air of the working zone and the urban environment.

We explore the problem of the control system design of train asynchronous electric traction drives. The proposed train autopiloting contrl system ensures complex optimization of train traction, namely: keeping of desired speed of the wage wheels slippage relative to the rail thus ensuring the maximum traction; minimizes the loss of energy in the power unit of the electric traction drive under changing of speed and power of motion process. In order to solve the stated we use methods and principles of synergetic control theory

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.
