The Ukrainian real economy encounters similar problems that do not allow its rapid development – high level of wear of productive assets, lack of modern equipment, outdated technologies, inappropriate environmental measures, high rate of occupational injury, etc. All this requires designing of new tools to manage the development of such important sectors of economy as industry and rail transport. Therefore, the urgent issues at the current stage of development of these industries include the definition of conditions for fixed assets capitalization and the sources of its financing. The scientific novelty of the results is identification and justification of the capitalization main components, determining the sources of funding and the mechanism for their attraction. The tool for managing the productive and environmental protection assets capitalization has been designed which is optimized using a two-dimensional dynamic programming model. The results obtained are the basis for the practical solution of the problem, and for further scientific research. This approach allows solving the problem of rail transport and industrial enterprises capitalization in a comprehensive manner, which contributes to their sustainable development.

Cost price reduction is one of the ways to improve the competitiveness of products. It is possible by establishing the set of factors affecting the production costs at an industrial enterprise and building on this basis a mathematical model of in-house cost management. The study objective was to develop and substantiate an economic-and-mathematical model of management to minimize the enterprise costs taking into account the utilization of secondary resources obtained in the production of basic products. The model consists of two stages. At the first stage, full costs of production of basic and additional products are determined. The peculiarity of this production implies the generation of significant amounts of secondary resources that have both independent value and opportunities for their use in the main technological process. This leads to complex material flows within the production process, which were accounted for in the study with the help of an adapted "cost-output" balance model. A plant can function with the use of a variety of raw materials which differ in both prices and rates of the output of basic products and secondary resources. This brings about the problem of finding an optimal combination of input resources to minimize costs or maximize profits. The problem is solved in the second stage. It is formalized as a linear programming problem. It features the provision of the ability to establish indicative plans of production of both main products and by-products. The model was tested on the example of coke-chemical plants producing coke of KDM-2 grade with 6 % humidity content and KDM-1 grade coke of improved quality as the main products. Coke oven gas, coke fines, beans, and sludge are produced as by-products. After purifying the coke oven gas, it is further used in the production of heat and electricity, compressed air, and a fuel for coke ovens. Thus, the produced fuel and energy, utilizable material resources, and circulating water supply are secondary resources. A certain portion of by-products is sold to third parties. When applied, the model will make it possible to improve the efficiency of cost management at enterprises

Подрез О. І. Інструменти управління сталим розвитком промислового підприємства: теорія та практика застосування Метою статті є визначення теоретичних основ формування комплексу інструментів управління сталим розвитком промислових підприємств. Виявлено, що в економічній літературі існує багато розбіжностей щодо видів інструментів управління сталим розвитком підприємства та їх кількості. Проведено дослідження рейтингу ТОП-10 інструментів управління підприємством за щорічними даними консалтингової компанії Bain & Company, які дозволили встановити найбільш популярні з них для суб'єктів господарювання. При формуванні комплексу інструментів управління сталим розвитком промислового підприємства враховано: досвід розвинутих країн світу щодо їх використання, функції підприємства (інформаційно-правова, виробнича, маркетинг-менеджмент, соціальна відповідальність) та напрями його розвитку (соціальний, екологічний, енергетичний, економічний). Запропоновано інструменти управління підприємством класифікувати за методами забезпечення на інформаційнозаконодавчі та аналітико-розрахункові.

The article is aimed at studying the essence of the definition of «global economy», as well as the impact of modern transformation processes on the activity of the State and enterprises in the sphere of social protection and social security of workers and population. On the basis of terminological analysis, the essence and characteristics of the global economy as a constantly changing process concerning the unification of countries into a single informational, economic, ecological and social space have been determined. A systematization of positive and negative consequences of globalization in relation to the development of the social sphere of developed countries and developing countries was carried out. It is proved that, under the influence of the negative consequences of globalization, there is a need to form a system of social protection, which is based on the use of social security at the level of the State and at the level of enterprise, in accordance with types and instruments. At the State level, social security is divided into such types as: legal and administrative, economic, ecological, material and energy, and medical, and at the enterprise level as financial, ecological, material and energy, medical, and legal. This distribution allows taking measures for social protection for specific types of social security. A chain has been built to eliminate the impact of negative consequences on the social sphere, namely: the consequences of the impact of the global economy – social consequences – social protection – social responsibility – social partnership. In further research, it is advisable to build a conception of social responsibility management of enterprises, which is aimed at developing and implementing social protection measures, as well as to determine the structure, components and instruments of the mechanism for its implementation.
