Full textThesis for the degree of Candidate of Economic Sciences (PhD) in specialty 08.00.04 – economics and management (of economic activity). - National Technical University «Kharkiv Polytechnic Institute», Kharkov, 2019. In dissertation work the theoretical and methodological positions of anti-crisis management of domestic machine-building enterprises based on the use of radical tools of redesigning of production processes are considered. The author formulates his own scientific position regarding the characterization of the reengineering of production in crisis management as an active strategic method, which allows to optimize production processes in heavy engineering enterprises and their associations in order to provide a quick response to the manifestations of the crisis in order to further enable the functioning of the crisis. The methodical approaches to the systematization of production processes of enterprises of heavy engineering, which are distributed according to the types of production at each stage of the production cycle, are improved, and they allow to formulate a concretized list of basic and auxiliary production processes as objects of reengineering. The dissertation substantiates the methodical approaches to the analysis of the patterns of construction and formation of the content content of the model of production reengineering at the enterprises of heavy mechanical engineering, which takes into account the use of tools of concentration and specialization of production and is based on the experience of process management of domestic enterprises, due to which it is possible to adapt the developed model for various enterprises of mechanical engineering and their associations using certain stages of the project of reengineering of production va modeling of production processes in accordance with their role in the production cycle of heavy machinery enterprises, which simplifies the process management system and reduces the cost of providing processes. There is determined that the core capabilities of reengineering in the crisis overcoming are: improving the basic performance of the enterprise by optimizing its production processes, improving production efficiency by redesigning logistics and technological processes, changing the structure of fixed assets and working capital in carrying concentration of production. The diagnosis of generalized financial and economic indicators of heavy engineering industry determine the main objects of reengineering the production:fixed assets (workshops, production space, equipment, intangible assets); production technology; internal logistics; organization of personnel; system of organization of raw material supply. The developed model of reengineering of production in crisis management enables structured crisis management tools, extending them through innovative approaches. Model reengineering of production involves the use of concentration, specialization and diversification within the association and each company separately, implementation of lean production, quality control systems and the creation of technological and engineering centers. Crisis management using reengineering is carried out by optimizing production processes, improving logistics, introducing a system of motivation, and improving the personnel supply system. The stages of implementation of the project of reengineering of production at heavy machinery enterprises were formulated and substantiated. At the preparatory stage, the company's diagnosis and construction of the project objectives tree are underway. The implementation phase includes modeling processes, determining options for conducting concentration, identifying and describing risks, forecasting results. The implementation phase involves concentrating, specializing and diversifying production, re-designing processes, creating incentive systems and quality management, optimizing staffing structure. The final stage is presented by the calculation of the project's performance indicators and the comparison of the performance with the expected. The paper assessed the efficiency of project implementation reengineering of production at enterprises of heavy engineering associations using the calculation of discounted cash flow, net present value, profitability index and internal rate of return. It is possible to find out what are the main factors of success: determination and consideration of risk exposure, ensuring a continuous process of project management and engagement group of specialists from different spheres of production, the use of innovative redesign of manufacturing processes, efficiency of use of radical crisis management tools for fixing achieved change. The methodical provision of crisis management by industrial enterprises is improved on the basis of the developed model of reengineering of production by expanding the functionality methods for optimizing production processes and interprocess relations, concentration and specialization of production. For the developed model, the means of implementing the strategic objectives of the project of reengineering of production are systematized, in accordance with the system approach in grouping executed operations in terms of content and objects, which allows to monitor and coordinate the implementation of strategic objectives at all stages of the project reengineering production.

Full textДиссертация посвящена изучению проблемы аэротехногенного загрязнения окружающей среды в районе воздействия горно-химических предприятий. В диссертационной работе решена важная научно-практическая задача по установлению особенностей формирования экологической опасности горнохимических предприятий и выявлению масштабов их влияния на элементы окружающей среды, а также разработаны природоохранные мероприятия и средства, уменьшающие влияние отходов калийных производств на окружающую среду. Рассмотрена концепция изучения процесса распространения выбросов промышленных предприятий в приземном слое атмосферы. Построена математическая модель рассеивания выбросов, а также получены зависимости дальности полета частиц от их плотности, размера, высоты источника выбросов и скорости ветра. Рассматривая солеотвалы Домбровского карьера как источник вредных выбросов, также построена математическая модель пылевого рассеивания под воздействием силы ветра. Разработанные математические модели рассеивания вредных веществ позволяют оперативно оценить масштабы загрязнения территорий, подвергшихся аэротехногенному влиянию не только при лимитированных выбросах, но и при аварийных. Приведены результаты экспериментальных исследований аэротехногенного загрязнения зоны аэрации соле-отвалами Домбровского карьера. Изучено и обосновано явление повышения водопроницаемости глинистых почв при увеличении концентрации солевого фильтрующего раствора. Для упрощенной модели баланса массы вещества, растворенного в элементе водоносного пласта, предложена методика определения уровня загрязнения подземных вод путем расчета концентрации мигрирующего вещества. Для эффективного подавления пыли на территории дробильно-сортировочного комплекса разработана автоматизированная установка и проведены ее испытания с использованием поверхностно-активных веществ. Изобретен способ очистки воздуха от пыли воздушно-механической пеной высокой кратности при транспортировке и переработке калийных руд. Этот способ будет использован при реконструкции калийных производств ОАО “Гирхимпром”.
Dissertation is devoted to the investigation of the aerotechnogenical contamination problem in the area of mine-chemical enterprises activity. In the dissertational work the important scientific-practical task of establishment features of forming ecological danger by mine-chemical productions and size detection of their influence on the environment is decided, and also the nature protections measures and means of decrease the potassiums production wastes influence on the environment are elaborated. The mathematical model of the harmful matters dispersion in the atmosphere, taking into account the height of ejection source, speed of wind, density and size of particles, is constructed. The results of experimental researches of aerotechnogenical contamination of the environment by salt dumpes of Dombrov quarry are presented and the phenomenon of increasing water permeability of clay soils with growing concentration of salt filtering solution is substantiated. For the simplified model of the admixture mass balance, placed in the water stratum element, the methodics for definition the pollution level of the underground water basing on the estimation of the concentration the migrated admixture, is suggested. The method for cleaning air from dust is invented. This method will be introduced at the reconstruction of potassiums productions OAC “Girhimprom”.
