МОДЕЛІ ПРОГНОЗУВАННЯ В МЕХАНІЗМІ РАННЬОГО ІНФОРМУВАННЯ І ПОПЕРЕДЖЕННЯ ФІНАНСОВИХ КРИЗ У КОРПОРАТИВНИХ СИСТЕМАХ

The paper is devoted to the problem of preventing financial crises in corporate systems, whose activities are becoming more and more complex in the context of globalization. The mechanism of early informing and crisis prevention in corporate systems is proposed, and includes five main modules: an analysis of the financial condition of the corporation, an analysis of the financial condition of subsidiaries, an evaluation of the impact of the financial crisis on a subsidiary on the threat of bankruptcy of the corporation as a whole, forecasting the financial condition of subsidiaries and corporation as a whole, anti-crisis management. The first four modules of the mechanism are the modules of implementation of proactive crisis management in the corporation, aimed at preventing the emergence of a crisis state, both in individual elements and in the corporate system as a whole. The fifth module is used in conditions of the current negative estimation of the financial condition of the corporation, and it is a "response" to existing crisis processes and phenomena in the corporation. After its implementation during the process of monitoring of the financial condition, proactive control modules are started to be used to allow early diagnosis and to prevent a crisis state. Particular attention is paid to such modules of proactive management as the evaluation of the impact of financial crises of subsidiaries on bankruptcy of the corporations as a whole and forecasting financial crises. A model basis for these two modules was developed. Neural networks, the mathematical apparatus of fuzzy logic, and the Caterpillar method were used for developing the models of estimation of the crisis threat in the corporate system. The developed set of models allowed to estimate the threat of financial crises in the parent enterprise and in the subsidiaries of the corporation, not only in the current but also in the perspective periods. The obtained results indicate that the financial condition of the investigated corporation is characterized by low level of the bankruptcy threat. Along with this, there is an increase in the threat of bankruptcy in a number of subsidiaries in the perspective period and the strong impact of local crises on the financial position of the corporation as a whole. The latter leads to the need of implementation of the anti-crisis measures in the corporate structure. An adequate tool for choosing anti-crisis measures and developing scenarios for the implementation of the anti-crisis management strategy is simulation modelling based on the concept of system dynamics.Рассматривается проблема предупреждения финансовых кризисов в корпоративных системах, деятельность которых становится все более сложной в контексте глобализации. Особое внимание уделяется оценке влияния финансовых кризисов дочерних компаний на банкротство корпораций в целом. Для оценки угрозы кризисов в корпоративной системе используются нейронные сети, математический аппарат нечеткой логики, метод «Caterpillar».Розглядається проблема запобігання фінансовим кризам у корпоративних системах, діяльність яких стає дедалі складнішою в контексті глобалізації. Запропоновано механізм раннього інформування і попередження криз у корпоративних системах, який включає п’ять основних модулів: аналіз фінансового стану корпорації, аналіз фінансового стану дочірніх підприємств, оцінка впливу фінансової кризи на дочірньому підприємстві на загрозу банкрутства корпорації в цілому, прогнозування фінансового стану дочірніх підприємств і корпорації в цілому, антикризове управління. Перші чотири модулі механізму є модулями реалізації проактивного антикризового управління в корпорації, спрямованого на недопущення появи кризового стану як в окремих елементах, так і корпоративної системі в цілому. П’ятий модуль використовується при поточній негативній оцінці стану корпорації і є «реакцією» на вже наявні кризові процеси і явища в корпорації. Після його реалізації у процесі моніторингу стану застосовуються модулі проактивного управління, що дозволяють здійснювати ранню діагностику і попереджати кризовий стан. Особливу увагу приділено таким модулям проактивного управління, як оцінка впливу фінансових криз дочірніх компаній на банкрутство корпорацій у цілому, прогнозування фінансових криз. Розроблено модельний базис цих двох модулів. Для побудови моделей оцінки загрози кризи корпоративної системи використовуються нейронні мережі, математичний апарат нечіткої логіки, метод «Caterpillar». Розроблений комплекс моделей дозволив оцінити загрозу формування фінансових криз на головному і дочірніх підприємствах корпорації не тільки в поточному періоді, а й у перспективному. Отримані результати свідчать, що фінансовий стан досліджуваної корпорації характеризується низьким рівнем загрози банкрутства. Поряд із цим спостерігається посилення загрози банкрутства на низці дочірніх підприємств у перспективному періоді і сильний вплив локальних криз на фінансовий стан корпорації в цілому. Останнє призводить до необхідності здійснення антикризових заходів у корпоративній структурі. Адекватним інструментом вибору антикризових заходів і формування сценаріїв реалізації стратегії антикризового управління є імітаційне моделювання, засноване на концепції системної динаміки

Organizational Changes in the System of Regional Development Management

The authors have proved that the problem of reforming the administrative-territorial structure in Ukraine is moving from the level of staging and discussion to the practical plane of implementation. A particularly influential impetus to the acceleration of these changes was given by the process of creating amalgamated territorial communities (ATCs) in Ukraine. Currently, the next stage of reforming local self-government is taking place in Ukraine, which is the consolidation of districts. In the process of formation of new districts, it is proposed to use information on the development of ATCs and take into account the EU experience in this area, which in the future will lead to an increase in the efficiency of the use of available resources along with the improving of the standard of living of the population against the background of betterment of the ecological situation in the region. The study substantiates proposals for applying a process approach to the consolidation of districts. The advantages of implementing these proposals include: consistency with EU structures in the field of district management; the possibility of implementing the conception of «RURBAN»; ensuring sustainable development of the region; increasing the importance of ATCs in the process of territorial management, etc. Success in development depends not only on the starting potential, but also on the mechanisms of development management, one of which can be considered the mechanism of «balancing resources, directions, tasks and methods of development management». The implementation of measures of suburbanization (the process of growth and development of the suburban zone of large cities, as a result of which urban agglomerations are formed) will ensure long-term economic growth of the regions, improve the standard of living of the population and achieve other strategic goals. In the suburban area, the «middle class» of the population should appear and grow. And for this it is important to organize and support the transfer «out of town» of industries, housing, infrastructure, organize eco-protection of systems, create a suburbanization economic space, cultural, tourist and recreational space, developed and high-quality infrastructure for life support of the population and transport links

The Task of Developing the Managerial Accounting in the Technology of Resource Saving

The article substantiates directions and ways of improvement of the system of information provision of the water supply and sewerage enterprises, oriented towards the organizational-economic innovations in the course of implementation of resource saving programs. Tasks of further development of managerial accounting as the basic component of analytical function of management are defined. Priorities as to the order of development of modern mechanism for resource saving are suggested, intellectual capital is allocated as the main factor of influence on the process of enterprise development. It is determined that a significant negative contribution to the aggravation of the problem up to the level, when enterprises fall into the unprofitable mode of activity, which tends to persist for a long time, is made through imperfect methods and mechanisms for management of resource use and resource-saving, and this negativity is then complemented with an imperfect information base, which, first of all, needs to be modernized in the system of management accounting

Regional Features of Startups Ecosystem Development: The Entrepreneurial Aspect

The article provides the definitions of the concept of both a startup and a startups ecosystem, on the basis of many analyzed scientific works of both domestic and foreign scholars. It is proved that the startups ecosystem is understood as a network that unites various subjects of the innovation process (universities, venture capital companies, marketers, entrepreneurs, audit and consulting agencies, etc.) that interact with each other on the basis of certain agreed «rules of the game». The overall startups ecosystem is taken for an example, being represented by four levels (global (international); national; regional; local). Each of the individual levels creates conditions for the development and successful functioning of startups. The publication presents in more detail the totality of participants in the local startups ecosystem, where it is determined that universities play a rather important role in the processes of formation of innovation ecosystems. The model of the innovation ecosystem of the university is represented by scientific research units, such as the research department, research institute, research sector, which include both the units in which research is carried out (scientific departments, laboratories, centers) and scientific and auxiliary structures (departments of scientific and technical information, research support, financial planning, and personnel). During the formation of an innovation ecosystem of the university, it is important to carry out the process of commercialization of innovative ideas. The importance of developing a startups ecosystem in entrepreneurship is proven. The State authorities are obliged to support, stimulate and encourage the development of entrepreneurship both in the country in general and in its regions in particular. The main programs of development and support of entrepreneurial activity at the regional level are analyzed. It is proved that supporting entrepreneurship in Ukraine by creating a favorable climate for the development of entrepreneurship, identifying all the components that stimulate the formation, attraction of new and expansion of existing small and medium-sized businesses is one of the main directions of implementation of the policy of economic development of the State and its regions

Regional Clustering with Account of the Urban Life Support Enterprises

The publication examines the problems of housing and communal services, which consist in the unprofitable operation of housing and communal services enterprises, significant amounts of receivables and payables, outdated equipment and lack of finance for their modernization, etc. Potential participants and directions of socioeconomic development in the form of a «Regional Cluster of Urban Life Support Enterprises» are formed. The authors propose to integrate urban life support enterprises into a corporation of utilities of water supply, sewerage and heat supply, which will consist of combining: the enterprises from other sectors; the areas of intellectual development, the enterprises for diversification of services; the regional water refinement complexes; the grouped water supply enterprises; and a municipal information and analytical enterprise. It is noted that in the developed countries of the European Union there is a significant number (more than 2 thousand) of quite similar clusters, and up to 100 countries have programs for creating clusters today. Strategic ways for further work on the formation of such cluster formations for urban life support enterprises of Ukrainian cities have been elaborated. These include: 1. Identification of strategic directions of reform and development. 2. Innovative development of management processes. 3. Innovative development of management technology. 4. Innovative development of the enterprise management system. 5. Development of methods of information and analytical support of enterprise management. 6. Proposal of innovative methods and measures for diversification and integration of activities. 7. Proposal of restructuring models. 8. Proposal of models of the public-private reform. 9. Proposal of models of socioeconomic and intellectual clusters as a strategy for innovative development of both the enterprise and the region. 10. Proposal of individual innovative projects (measures) in the sphere of production and commerce to improve financial and economic sustainability and production-economic reliability

The System Block of «Energy Saving» in the Strategy of Reforming the Housing and Communal Utilities

Housing and communal utilities is an independent branch of the national economy. The purpose of functioning of the housing and communal enterprises is to satisfy the needs of the population and economy units in the services that provide normal conditions for life and work. In housing and communal utilities, an important place is occupied by enterprises of water supply and wastewater disposal. One of the largest housing and communal enterprise in City of Kharkiv and Kharkiv region is the KP «Kharkivvodokanal». At present time in the system of KP «Kharkivvodokanal» the preparatory work is carried out in terms of elaboration of the program mechanism for management of the energy saving process in the composition of reformation measures for the period up to 2020 and for more distant temporary horizons. Thus, the article proposes a variant of a energy management scheme. The calculations showed that the organization of resource saving at enterprise includes technical and technological, human, intellectual, financial, information, political-legal, ecological and other elements, which are an important and integral part of energy saving

POTENTIAL OF BUSINESS ENTITIES: ESSENCE, ASSESSMENT AND ROLE IN NATIONAL DEVELOPMENT

The behavior of macroeconomic indicators (reflecting the development of both the national economy as a whole and that of individual economic sectors) testifies to the low current efficiency of the functioning of economic entities in the context of economic activities. This in turn necessitates scientific substantiation of developing and introducing theoretical and methodological recommendations to ensure innovative development of the country. One of the most effective ways to practically implement this task is to substantiate methods for quantitative assessment of potential in the context of economic activities. The practical value of applying these methods is that the results of the integrated assessment of potential can be used as a criterion for the priority development of certain economic sectors or economic activities

Economic Security Threat Modelling of a Commercial Bank in a Globalized Economy

In the paper, one develops a set of models for diagnosing threats to the economic security of a commercial bank, which allows improving the quality of decisions forming and making on managing the safe functioning and development of the bank. The bank's economic security research system has been developed, it includes 3 main blocks: research information space creation; assessment and analysis of the security of a commercial bank; generalization, and formation of decisions on the economic security of a commercial bank. The research made it possible to draw an inference of a theoretical, methodological, and applied nature that reflects the solution of the tasks set following the purpose of the study. A set of models has been built with modern tools of economic and mathematical modelling to improve the quality of decisions made to manage the bank's security and reduce the risks of threats. A model for calculating the bank's economic security indicator has been developed, which includes the following main stages: the construction of a structural scheme taking into account the rules of the theory of banking functioning security, then the terms and their membership functions are set for each input and output variable of the fuzzy inference system under consideration. Results of the response surface for the model are shown in the figure on the graphs of the dependence of the bank's economic security indicator on various input components. The paper requires that it is convenient to diagnose the state of economic security of a bank using fuzzy logic, this allows getting a clear quantitative representation of economic security state of the bank, as the indicators used for diagnostics may be indistinct and approximate and this a priori cannot give an adequate result when accurately calculated
