For the economic analysis of railway enterprises assessment the special form has been worked out. The results of the economic estimation allow the economic subject supervisor to obtain analytical material for the managing decision making. One of the main trends of economic subject activity is economic state assessment on the basis of analysis with up-to-date management theory based on economic information technologies that allows to compare production transformation results on the temporal periods and related economic subjects. The peculiarity of this economic assessment method is that all indexes used in the analysis have the same direction vector, i. d. the higher index, the more favorable economic state of analysed economic subject.

The development of the approach to multi-criteria robust optimization is presented in article by developing of a technological machines robust optimization method in a joint synthesis of a parameters and tolerances on them. The ability to search for optimal solutions is the advantage of the proposed method in the absence of functional dependencies for single quality parameters from the input parameters that have extreme character and in terms of the existence of intuitive perception about their best averages. A structural (functional) synthesis, a parametric synthesis and a synthesis of tolerances theories were used to develop a method. This article may be useful for researchers studying the problems of finding optimal solutions during the implementation stages of creating and implementing life cycle of technological machines and for researchers studying the problems of improving the quality and competitiveness of technological equipment in domestic enterprises.

"Effective and affordable sorbents produced from natural organic raw materials and waste products of agricultural and livestock origin, because these sorbents are part of existing ecosystems and, therefore, best meet environmental requirements, in order to ensure the rational nature management and preservation of consumer properties of water resources. For the solution of actual problems, such as the removal of oil and oil products from water surface, as sorbents was investigated by the waste processing of leather and agricultural industries: wool (sheep and goat) and feather (chicken and waterfowl). It is established that application of organic and mineral acids at certain concentrations , for treatment of wastes from the processing of wool allows to obtain sorbents directional spectrum for removal of oil products (such as diesel gas oil and engine oil) and oil from water. The modifiers of wool and feathers obtained after the chemical treatment, was used to study the sorption of oil and oil products from water surface. It was determined by sorption characteristics of the modified sorbents, such as oil capacity and moisture absorption. The kinetics of sorption–desorption of oil, which showed that the greatest degree of absorption is observed for the first 10-15 minutes. It is found that wastes from goat and sheep wool have a 90% holding capacity that persists in time. It was revealed the effect of temperature on oil absorption capacity of the sorbent and the calculation of heat of adsorption. The temperature increase leads to a reduction of the capacity of emulsified oil, reducing the degree of purification by 15-30%."

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.

Construction of three-dimensional structures faces the need to cover the hard concrete layer with lightweight insulation and waterproof carpet. This combination of materials with different mechanical and physical properties requires the creation of methods for determining the stress-strain state of elastic composite layer lying on absolutely solid. According to these criteria the general solution of elasticity theory problem for each layer has been calculated. The system of differential equations is solved. A homogeneous solution can be used to study various problems of stress state in a layer. Formation of the problem of infinitely extending beamless surface has been drawn as an example. These solutions can be used in studding various problems of stress state layer. The solutions of engineering problems require the definition of complex roots of transcendental characteristic equation. In this paper, the roots were determined by Newton`s method. The obtained roots of the characteristic equation determine the stress and displacements in each point of a composite layer.

The work is dedicated to the analysis such indicator of the contentious background as an emotional state. The study has both theoretical and practical orientation. The theoretical framework discusses the origins of the relationship of latent protest with this indicator. In practical terms, the work adapts to the problem conditions previously developed measurement technique according to the technology of semantic differential. Testing was conducted on the basis of concrete experimental data obtained by questionnaire survey among students DSTU (faculty "Innovative business and management") at the end of 2015. The Survey was of a pilot nature, was attended by 79 students, mostly 2 - 4 courses. To measure the affective component respondents were asked to characterize the semantic scales of his real emotional state, as well as two perfect construct. Measured the affective level of perception of the emotional state based on the proximity in the semantic space of the image of the real object to ideal constructs. In particular, in the linear approximation, as polprasert the appropriate relative distances. In addition to the distribution functions of the searched level of the respondents obtained through the linear approach, the paper presents updated results. The latter was calculated according to adapted for these purposes, a previously developed stochastic non-linear model. In models of individual affective level of perception was defined by stochastic integro-differential equation of gradient type. Which is numerically solved using the agent-oriented simulation package AnyLogic. Using Monte Carlo for these solutions was determined by the statistical parameters of the study audience, such as the responsibilities in the distribution of the respondents affective level of perception of their emotional state. In the whole group received a neutral level of perception of the emotional state, the average for all respondents the value zero. A large part of the studied audience (81%) showed a positive or moderately negative emotional state. And this indicator is not characterized by a high degree of conflict. And only a small portion (9%) is very negative (from -0,6 to -1 on a scale from -1 to +1) emotional state, contributing to the development of the protests. The result shows the potential of the developed method of measurements to assess the risk of political tension. This is the first main result. In particular, for the study of the audience revealed that this subgroup of the risk is 9% of the respondents. Note that this estimate coincides with the results of the monitoring in the affective perception of political orders, also conducted earlier among the students of the same faculty. The second important result is connected with a comparative analysis of affective and cognitive component of perception of emotional state. The cognitive component was determined for the appropriate group of questions in the same questionnaire. It is found that when cognitive appraisal of their emotions by the respondents at the average position values that are different from the actual feel. This indicates the failure of the direct conventional estimates of emotional state and the need of measuring the affective component.
