Quantitative assessment of investments: regional eco-efficiency
(Commission of Motorization and Energetics in Agriculture, 2016) Voytsekhovska, V.; Simak, A.; Voytsekhovska, Yu.
The article is dedicated to development of the methodological approach to determine the most effective ways and areas of investments use aimed at reducing the negative impacts of pollution. This takes into account the reality that the level of pollution is different for different areas (regions), and the degree of negative impact is due to two main factorsvolume of gas emissions and the number of residents living in these territories. Taking into account the lack of quantitative laws regarding the impact of pollution on human lives the expediency to limit some qualitative considerations that significantly contribute to the solution of the problem are developed in the article. The paper develops analytic approach, which is based on establishing the parameters that characterize the essence of the developed phenomenon. The state of air pollution in particular is seen as the main factor that significantly affects the residents’ life quality. At one and the same degree of negative pollution, its effect will depend on the number of residents living in the area. As our research continues with the assessment of air pollution reduction state, where two indicators were developed – harmful gas components in the air and population density in the area. Based on the hypothesis of parabolic type, the corresponding functional relation between the parameters proves, that the product of assumed parameters determines the priority of pollution reduction in some areas. The conducted proposed approach to interpretation of dust pollution on the example of regions of Poland is developed.

The technology of hierarchical agglomerative cluster analysis in library research
(Commission of Motorization and Energetics in Agriculture, 2016) Кunenets, N.
This article describes the simple technology of the hierarchical agglomerative cluster analysis of 20 different libraries, presented by the samples of classification attributes of the same volumes. It is necessary to construct a proximity matrix for an effective process of cluster analysis, using the data from the table “library-classification features”. For separating a set of selected objects into clusters, so that each of them has objects, the most appropriate for its type, it is necessary to create a table “object-property”, where libraries are objects and individual and equal dimension vectors (sets) of characteristic classification features are properties. To do this you should: form the set of libraries that are the objects of clustering; define for each library the set of classification features and its power (volume) in the same nominal scale; choose the value scale of classification features; form a table object-property. This technology is implemented in the environment of MsExcel-2003. It includes the transformation of one-dimensional data into multi-dimensional indexes, using the descriptive statistics and distributions of individual parameters, the creation of the “object-property” table, the building of the proximity matrix, the definition of the dendrogram structure and the cluster interpretation. The application of clustering method can further focus on creating algorithms of effective information search, and also building the scientifically-reasonable classification systems orientated on the library science. The method of hierarchical agglomerative cluster analysis can be used with typological or semantic distribution of library funds, or studying of their thematic and specific composition. This method can be considered as universal, that gives an opportunity to formalize the typology division of any objects of librarianship.

The article investigates improvement of the supply chain according to the requirements of nowadays, particularly impact of natural disasters. The main role in this process is given to humanitarian logistics. The phases of the disaster and the actions of humanitarian supply chain during these phases are analyzed. It is very important to understand in which cases more appropriate using particular type supply chains. From this point of view authors analyzed the main differences between commercial and humanitarian supply chains. The most important role in the supply chain during the crisis situations played humanitarian organizations. For the purpose of comprehensive understanding peculiarities and involve members were identified main participants of humanitarian supply chain. The ranking of donor countries that are in the top 10, and examples of humanitarian operations and logistics companies in the aftermath of disasters are shown. Authors analyze usage of model of disaster management by logistics companies and humanitarian organizations in different disaster stages. The main advantage of proposed approach is getting clear criterion which arises during the recovery phase of the disaster and enables logistics companies, humanitarian organizations and the military to integrate their efforts and logistics performance, and adapt them to the specific needs.
Investigation of mathematical models for vibrations of one dimensional environments with considering nonlinear resistance forces
(Commission of Motorization and Energetics in Agriculture, 2016) Pukach, P.; Sokhan, P.; Stolyarchuk, R.
In this paper we consider important classes of one dimensional environments, bending stiffness of which can be neglected. It is impossible to apply approximate analytical method of solution of mathematical models of dynamic processes. So justification of existence and uniqueness of solutions, carried out a qualitative their evaluation, based on numerical analysis are considering in this paper. Also the features of dynamic processes of some of examined class of systems are analyzed. Methods of qualitative study of oscillations for restricted and unrestricted bodies under the influence of the resistance forces, described in this paper are based on the general principles of the theory of nonlinear boundary value problems – Galerkin method and the method of monotonicity. Scientific novelty consists in generalization these methods of studying for nonlinear problems at new classes of oscillating systems, justification of solution correctness for specified mathematical models that have practical application in real engineering vibration systems.

(Commission of Motorization and Energetics in Agriculture, 2016) Bublyk M.; Rybytska O.
In order to study the social component of man-made damage in the national economy, an expert model for establishing levels of technogenic morbidity of the population of Ukraine, due to the destructive influence factors (emissions, discharges, waste), have been built by means of fuzzy logic in this paper. The economic evaluation and prediction of the social component of man-made losses – cost of treating patients with tumors due to environmental pollution have been conducted. In the national economy these results should be considered in the formation of public expences on health care and the treatment of patients. This will increase the effectiveness of state regulation of the phenomenon, provide appropriate allocations for their eradication and compensation.
Double-sided analysis of the labor market in Ukraine: graduates’ and employers’ view
(Commission of Motorization and Energetics in Agriculture, 2016) Horbal, N.; Shpak, M.; Shpak, Y.
The current state of the labor market in Ukraine is researched. A lot of processes are irregular and uncontrollable as a result of shadow or informal employment at the market nowadays. Different structural and cyclical influences caused high unemployment and a gap between labor market needs and labor force qualification and education. The impact of the political crisis on employment has been related to a large and growing internal flow of people leaving the areas of warfare and looking for new jobs. The migration of the working age population to other countries has accelerated over the last years. Thus it is important to increase the economic activity of young people by reduction of imbalance between supply and demand for labor, reduction of shadow employment, labor migration of young people. The problems and difficulties for university graduates in the job search and difficulties for employers related to hiring educated young people in the conditions of considerable supply of labor in the Ukrainian labor market are analyzed. The gaps of labor demand and supply are considered from two directions: graduates’ view – challenge of finding jobs for young people; employer’s view – complexity of the employee selection with a high employment potential and an adequate psychological portrait. The measures for preventing and solving the mentioned problems are proposed, among them innovative ways of interviewing and an algorithm for employers for finding highly skilled workers. It is stressed that the problems of employment in Ukraine can not be addressed in isolation from the global processes on the world labor market. The Association between Ukraine and the EU may have a significantl influence, increasing the number of migrant workers and mobility.
Economic problems of aircraft equipment recovery
(Commission of Motorization and Energetics in Agriculture, 2016) Poplavska, Z.; Kalynovskyy, A.
The formation of effects of different order in the process of aircraft equipment recovery is investigated. Changes of idle time of aviation equipment, depending on the cost of its recovery and maintenance are estimated. Economic problems of reasonable implementation of qualitative aircraft recovery are considered. Unlimited theoretical limits of costs on assuring the quality of aircraft equipment recovery are shown on the graphs. Suggestions for reasonable limits of the cost on aircraft equipment recovery are grounded. It was established that the definition of economic efficiency of providing quality of aircraft equipment recovery requires accounting not only the cost but also the obtained effects. The model showing the possible operating modes of aircraft equipment is presented. Its partial review allows to evaluate the difficulties of calculating the economic effect of providing quality of aircraft equipment recovery. Theoretical aspects of economic effect formation of quality of aircraft equipment recovery are investigated. It is stated that the annual economic effect from assuring quality of recovery and maintenance of aircraft equipment, resulting in operation of aircraft equipment (the effect of the secondorder), occurs in the form of savings and avoided losses for two reasons. First, eliminate losses due to non-compliance of technical parameters of aircraft equipment to normative and technical values. Second, due to changes in the operating costs connected with the elimination of aircraft equipment idle time due to technical reasons. Also, certain effect can be created in general within the whole branch of economics where aircraft equipment is used. Calculation of economic effect requires distinguishing between savings and avoided losses. Potential loss can be the cost of the aircraft equipment itself and damages that it may cause in case of falling. Also, losses can occur due to bad providing of technical condition indicators, and therefore efficiency of aircraft equipment causes inadequate change of operating costs and process in which it participates.

Model of sustainable development of the national economy of Ukraine: assessment of current state and prospects of development
(Commission of Motorization and Energetics in Agriculture, 2016) Kuzmin, O.; Shpak, N.; Pyrog, O.
The article considers the research of sustainable development model of national economy of Ukraine at the modern conditions. Determine the structural changes of national economy of Ukraine at the period of 2001 – 2012. During the period from 2001 to 2012 increase of the share of economic activities of the sphere of immaterial production, while reduction of the share of economic activities of the sphere of material production. The lack of progress in the development and implementation of new technologies prevented the improvement of industrial competitiveness, which partly led to a deep structural crisis and drop in production. The share of type of economic activity in the structure of the national economy does not affect its importance for the development of national economy. The poor energy efficiency of Ukraine poses a serious threat to its economic security that results in a deformed structure of production and consumption, in the usage of old technology of production of energy and in slow implementation of energy saving technologies. For sustainable development of Ukrainian national economy at unstable modern conditions must improving public-private partnership in the field of energy efficiency are substantiated.
