Документ An approach to assess the state of the HEI’s quality assurance system in context of requirements and recommendations of ESG(Khmelnytskyi National University, 2017) Григорук, Павло Михайлович; Григорук, Світлана Сергіївна; Hryhoruk, P.M.; Grygoruk, S.S.Документ An approach to construct fuzzy preference relationships for managerial decision making(Чернігівський національний технологічний університет, 2017) Григорук, Павло Михайлович; Хрущ, Ніла Анатоліївна; Григорук, Світлана Сергіївна; Hryhoruk, P.M.; Khrushch, N.A.; Grygoruk, S.S.Urgency of the research. The combination of theory and empirical experience of management with modern cognitive tools determines the necessity to use economic and mathematical modeling managerial decision making in conditions of variability, uncertainty and multidimensionality of the market environment. Target setting. The choice of managerial decision on the set of alternatives is essentially limited to the difficulty of forming a single criterion, which covers different, and in some cases, conflicting requirements. Additional complications are the need to take into account and formalize the uncertainty of both source data and purposes. These lead to the need for use of such models of description of the reality, that allow to process large amounts of data in conditions of the growth of uncertainty. Actual scientific researches and issues analysis. Tools of fuzzy set theory and fuzzy logic are currently an effective means of formalizing uncertainty in different areas of manager's activities: finance, economics, risk management, marketing and many others. These issues are highlighted in the writings of such scholars as K. Kovalchuk, A. Matviychuk, W.-Y. Cheng, L. Lin, M. Wen, Z. Qin, T. Korol and many others. Uninvestigated parts of general matters defining. Issues of description of fuzzy preference relationships based on the aggregate of values of several criteria measured in different scales, and development of scientific and methodological approach to select on this basis the set of most suitable alternatives as a decision currently are not solved enough. The research objective. The main objective of the paper is description of approaches to design fuzzy preference relationships based on the aggregate of values of several criteria measured in different scales, and development of scientific and methodological approach to select on this basis the set of most suitable alternatives as a decision. The statement of basic materials. The procedure of decision making is considered based on the creation of fuzzy preference relationship with membership function, which reflects the degree of confidence in the superiority of one alternative over another. The choice of alternatives carried out from subset of strictly non-dominated alternatives, based on fuzzy preference relationship. Conclusions. Given the availability a lot of criteria of effectiveness, the choice of decision should be based on fuzzy preference relationship. The developed scientific and methodological approaches are aimed to construct fuzzy preference relationship for comparison of alternatives on many criteria simultaneously. It allows to manager to form a set of Pareto-efficient alternatives and choose from them the best as a decision.Документ An approach to design a composite index of economic development and identifying the bounds of its levels(2019) Hryhoruk, P.M.; Khrushch, N.A.; Grygoruk, S.S.; Григорук, Павло Михайлович; Хрущ, Ніла Анатоліївна; Григорук, Світлана Сергіївна; Григорук, П.М.; Хрущ, Н.А.; Григорук, С.С.Paper considers the task of assessment of regions’ economic development level using composite index assessment technology. It is proposed to design composite index by block convolution of two groups of partial indicators. First group contains indicators measured in absolute scale. Second group consists of relative measures of dynamics. For each group we proposed own procedure for data normalization and own method for data convolution in partial composite index. The procedure for identification of intervals’ bounds on the composite index's scale for each level of economic development is proposed to the aim of classification of Ukraine’s regions. Presented means for identification of intervals’ bounds of data grouping may be used to solve other tasks independently from the way of design of composite index and set of initial indicators. The results calculated may be used in the decision-making system as source data for further calculations, as well as a criterion for determining the socio-economic development directions.Документ Assessment model of regions’ economy in the context of their sustainable development(2020) Hryhoruk, P.M.; Khrushch, N.A.; Grygoruk, S.S.; Григорук, Павло Михайлович; Хрущ, Ніла Анатоліївна; Григорук, Світлана Сергіївна; Григорук, П.М.; Хрущ, Н.А.; Григорук, С.С.Currently realizing the new active role of the region as a sustainable development entity is a strategic direction for regional policy's development. Assessing the sustainable development of regions is an important part of such a policy and facilitates the timely identification of internal and external threats, the development of the necessary stabilization measures to prevent their negative impact, and the formation of strategies aimed at the sustainable functioning of regional systems. The economic system is an important subsystem of the region. The article proposes an approach to assess the level of regions economic development in the context of ensuring its sustainable development. It is based on comprehensive assessment technology. The sustainable economic development composite index is calculated by a weighted additive convolution of partial indicators. A feature of the proposed approach is the simultaneous use of both metric and non-metric indicators. The metric component is used to calculate the composite index values. Weight coefficients are calculated by the principal component method using the factor loadings of the first principal component. The non-metric part of the initial data is used to refine these weights. The article describes the algorithm for calculating a composite index. The practical testing of the proposed approach is presented for the case Ukraine's regions. The results lead to the conclusion about significant problems in ensuring sustainable development of the regional economy. Outcomes obtained are very helpful for the public administration bodies to develop and revise the appropriate policy for solving the sustainable development problems in each region.Документ Model for assessing the internal quality assurance system(Хмельницький: ФО-П Сторожук О.В., 2017) Григорук, Павло Михайлович; Григорук, Світлана Сергіївна; Hryhoruk, P.M.; Grygoruk, S.S.Документ Model for Assessment of the Financial Security Level of the Enterprise Based on the Desirability Scale(2019) Hryhoruk, P.M.; Khrushch, N.A.; Grygoruk, S.S.; Григорук, Павло Михайлович; Хрущ, Ніла Анатоліївна; Григорук, Світлана СергіївнаModern economic realities of Ukraine in the conditions of growing destabilizing influences of external and internal environment convincingly prove that each year the influence of various threats on the level of financial security of economic entities increases. This necessitates constant monitoring of the financial security level in order to timely detect and neutralize possible crisis phenomena as a result of its decrease. The study aims to assess the financial security level of enterprises based on the theory of comprehensive assessment. The scientific and methodical approach to design a composite index of financial security and the identifying its level based on the double use of Harrington's desirability scale is proposed. The resulting model was tested on the particular enterprise data. The proposed approach may be used for another set of partial indicators, as well as in assessing the level of financial security at the national level. The results of the study may serve as the basis for making managerial decisions on raising the business entities financial security level and public administration.Документ Post-COVID-19 economic recovery in the context of SDG8 and SDG9: the case of selected Eastern European countries(IOP Conference Series: Earth and Environmental Science, 2023) Hryhoruk, P.M.; Khrushch, N.A.; Grygoruk, S.S.; Ovchynnikova, O.R.Assessing the economic development of countries in the context of the tasks defined in the UN 2030 Agenda for Sustainable Development is essential from the point of view of determining progress in achieving the SDGs. It becomes especially relevant in periods of global challenges and disturbances, one of which is the COVID-19 pandemic. The goals of SDG8 and SDG9 contain indicators that are determined mainly by the state of development of the country’s economy, so the analysis of trends in their changes is important in the context of identifying trends in economic growth in general, as well as for evaluating progress in achieving these goals. The purpose of the study is to identify the impact of the COVID-19 pandemic on the economic development of countries to achieve sustainable development goals and assess progress trends in the post-pandemic recovery of the economies of Eastern Europe by analyzing quantitative data from official statistical sources. The object of the study is the economic development of Eastern European countries in the conditions of the COVID-19 pandemic. The study period covers the time range from 2017 to 2021 and includes both the pre-pandemic and pandemic periods. Eight countries of Eastern Europe were chosen as research objects. Indicators of official statistics related to SDG8 and SDG9 sub-goals were selected for analysis. The study showed a significant decrease in the values of most indicators, which was caused by the destructive effect of the pandemic. To assess the possible development trajectory, we calculated the estimated value of indicators for 2022 using the Holt-Winters method. The results showed that, despite some progress in 2021, in 2022, the values of the indicators are decreasing. Such estimates correspond to the trends provided by international institutions. We have built a composite indicator to assess the economic development trend comprehensively. The results of the evaluation confirmed the general trend towards a decrease in the level of economic growth in the context of the goals of SDG8 and SDG9 for all the countries of Eastern Europe selected in the study.Документ The Rating Model of Ukraine's Regions According to the Level of Economic Development(2019) Hryhoruk, P.M.; Khrushch, N.A.; Grygoruk, S.S.; Григорук, Павло Михайлович; Хрущ, Ніла Анатоліївна; Григорук, Світлана Сергіївна; Григорук, П.М.; Хрущ, Н.А.; Григорук, С.С.The identification of the real level of economic development of the region is an important condition to design effective regional development policy. Economic development is characterized by a large number of indicators. This study provides an approach for assessing the level of economic development based on the use of a comprehensive index, which is a convolution of initial indicators. The model involves the use of both a group of absolute indicators and a group of relative measures of dynamics. Each of the groups of indicators has its special data normalization procedure and its special method of convolution into a partial comprehensive index. The outcome of the evaluation is obtained by weighted multiplicative convolution of partial comprehensive indexes. In this study, the level of economic development of regions of Ukraine according to the data of 2017 has evaluated. As a result, Ukraine’s regions were allocated into three groups: with the level of economic development above average, with the average level of economic development and with the level of development below average. The article suggests a way to determine the boundary values of the comprehensive index for grouping. Comparison of the obtained results of grouping with the results of clustering of the Ukraine’s regions by the k-means method with the same data showed their identity. The article shows that Ukraine’s regions can be allocated by the level of economic development into other number of groups.Документ Оцінювання результативності діяльності компанії(2018) Григорук, П.М.; Завгородня, Т.П.; Григорук, С.С.; Hryhoruk, P.M.; Zavhorodnia, T.P.; Grygoruk, S.S.Економічне зростання та подальший розвиток економіки України, окремих її галузей, неможливі без підвищення ефективності діяльності підприємств, що їх представляють. Від ефективності діяльності підприємства певною мірою залежить рівень досягнення його цілей, тобто його результативність. Результати оцінювання результативності дозволяють встановити масштаб і зміну спрямованості управління діяльністю підприємства, прогнозувати їх вплив на ключові функціональні підсистеми підприємства, сприяють ухваленню управлінських рішень, спрямованих на підвищення рівня ефективності його діяльності. В статті розглянуто підходи до змістового наповнення категорії результативності діяльності, встановлено її зв’язок з категорією ефективності діяльності. Зроблено висновок, що різноманітність підходів щодо трактування сутності категорії результативності зумовлена широким спектром її застосування та особливостями сфери діяльності підприємства. Визначено комплексність та багатокритеріальність результативності діяльності. Розглянуто підхід до оцінювання результативності діяльності, оснований на методі інтегрального показника. Проведено апробацію запропонованого підходу на прикладі двох наборів вихідних показників. Перший набір показників визначений за методикою Д. Сінка і складається з шести груп показників. Інтегральний показник побудований за методом блочної згортки і являє собою комбінацію часткових інтегральних показників, побудованих для кожної групи. Другий набір являє собою сукупність показників рентабельності. В статті проведені розрахунки за статистичними даними реального підприємства за період з 2013 року по 2016 рік. Встановлено зниження рівня результативності діяльності впродовж досліджуваного періоду часу. Зіставлення розрахунків за обома наборами показників показало ідентичність результатів. В статті запропоновано комплекс заходів для підвищення результативності діяльності підприємства.
