The paper proposes an approach to optimizing the functional structure of the business processes of a service IT company based on the business process management system as an active self-organized, viable system that takes into account the peculiarities of the information technology industry development. This allows to optimize the structure of business processes through adequate positioning and formal description of the whole set of complex hierarchical interconnections with the aim of transition from hierarchical to functional structure of enterprise’s business processes taking into consideration the relationships between elements. The designed business process management system is considered as a set of strategic, tactical and operational business processes that are interrelated within a single strategic goal. The graph of the functional tasks of the investigated service IT company is formed, which reflects the incidence and closeness of the links between business processes. The model of optimization of the functional structure of business processes is proposed based on the algorithm, which involves minimizing the total connections of the subsets of the vertices of the functional graph, with the help of which the optimal restructured system of business processes was constructed, which increases the efficiency of management of the investigated service IT company. The advantages and disadvantages of the restructured functional structure of the service IT company’s business processes were analyzed. It is determined that the restructuring of the business process system will be effective only with changes in the enterprise processes management based on appropriate management strategies.

The paper deals with the assessment of the socio-economic development of Ukrainian regions using Data Science methods and multidimensional analysis, including taxonomy, n-dimensional classification, and ensemble decision trees methods. The methodological bases of economic regions devel¬opment by the economic and mathematical modeling methods were investigated. The necessity of improving and further developing estimation models of the regional economic development using business analytics tools and multidimensional scaling methods was investigated.
The ensemble decision trees methods was applied for the classification model of economic development of the Ukrainian regions according to the conceptual base of the research on regional econom¬ic development. It will increase the quality level of administrative decisions making on regional de¬velopment asymmetry equalization. It is determined that in Ukraine, there is a significant imbalance of regions clusters with high and low economic level. Here was investigated the relationship between the two groups of economic development indicators – the indicators of the economic development regional performance and the group of economic potential. The results of the classification model allow identifying the set of indicators that have significant impact on the overall economic development. The developed ensemble model allows carrying out qualitative recognition and prediction of the state probability of economic development. It will improve the quality of decision making pro¬cesses on equalization of regional development asymmetry.
The further research gives the possibility to develop the system of levers directions of regional development imbalance equalization, to determine priority vectors of sustainable development of both the regions and the country. -

The actuarial present value of life insurance is found by solving a system of differential equations. The cases of both constant effective interest rates and variables, depending on the time interval, are examined. The authors used the Pontryagin maximum principle method as the most efficient one, in order to solve the problem of optimal control of the mixed life insurance value. The variable effective interest rate is considered as the control parameter. Some numerical results were given.

Modern technologies of detection and prevention of corruption in emerging information society
Problems and Perspectives in Management Volume 16, 2018 Issue #1 pp. 58-67 Views: 1931 Downloads: 418 TO CITE АНОТАЦІЯWith the development of the information society, there has been rapidly growing number of international research on the role of various (information, innovation, intelligent) technologies as a catalyst to fight corruption. As you know, the problems posed by corruption are economic, social and political consequences. In recent years economists and various researchers have shown increasing interest in studying the phenomenon of corruption. Many researchers in the field of studying corruption phenomenon are of theoretical nature, which studied different behaviors without having developed effective methods and technologies to identify and prevent corruption in the various spheres of government. In this regard, there is a need to study the world experience of application of technologies in the prevention of corruption and anti-corruption platform in Ukraine. This will allow to adapt them to positive experience in the implementation of mechanisms to identify and prevent corruption in Ukraine. The authors believe that to obtain a more accurate picture of the corruption situations that provide characteristics and its quantitative description is possible only by means of modelling the corruption phenomenon. In this regard, the analysis of theoretical models of corruption was made: the modelling made by the mathematical notation of the models and conclusions on the effectiveness of their application in management. Using simulation, the authors came to the conclusion that the detection and prevention of corruption should be carried out with the use of technologies and the system approach: from the study of statistics and use of anti-corruption platforms, public registers and databases to logical and probabilistic (LP) risk models of corruption.
