The article reveals the issue of structuring the regions of Ukraine by indicators of monetary valuation of agricultural land. On the basis of the data of the State Statistics Service of Ukraine the analysis of the structure of agricultural land was carried out, which made it possible to establish a fraction of the area of individual species of land in total. The focus is on the concentration of significant amounts of land in private ownership, which exacerbates the issue of land valuation from the perspective of possible resource management and efficiency in its use. It has been argued that fragmentation of land is one of the good reasons for the inefficient use and changing purpose of land, lack of financial resources and smallholder coherence. In accordance with the Law of Ukraine "On Land Assessment" and the data of directories of the State Service of Ukraine on Geodesy, Cartography and Cadastre for 2017 - 2019. A comparative analysis of the normative monetary valuation of agricultural land by regions of Ukraine was carried out, which became the information base for their structuring by the method of cluster analysis. It was substantiated that one of the powerful methods of multivariate analysis is the cluster analysis, which is based on a set of selected economic indicators and objects of assessment. Estimates are based on the monetary valuation of agricultural land such as: arable land, perennial plantations, hayfields and pastures. On the basis of mathematical standardization of values of indicators the matrix of imaginary Euclidian distances is calculated, became a basis for formation of 7 clusters, each of which includes a final number of objects-regions distributed on homogeneous signs and approximation on estimations of cost of land areas. The formation of clusters on such characteristics will identify the most similar groups of objects-regions to develop a system of monitoring changes in the cost of land resources with subsequent analysis of fluctuations relative to average levels within specific clusters, and in Ukraine as a whole.

Solving design problems involves the application of a systematic approach to managing computer systems, requires a separation of the design process and construction of the object with the establishment of real terms for each task, that is, the division of the general problem into elementary tasks and instructions for their implementation to individual specialists. The article deals with the rational structure of computer systems design management, which allows to increase the productivity of specialists with the existing contradiction between the established term of technological control implementation and the quality of project materials, taking into account the nature of work in the changes of internal and external conditions. The purpose of management of the design system is to maintain a rational functioning while performing the tasks with high performance and minimal costs. The systematic approach to design management establishes the composition of the links, defines the hierarchy, external and internal links, which are the basis for building a rational structure of the design management system. The design tasks have been identified and the computer system design management strategy has been identified. A rationally organized design management system allows to develop project materials at a high scientific and technical level with minimal refinements of TU during its implementation.

The paper substantiates the need of usage mathematical and computer modelling in data analysis in assessing with the functioning of logistic processes and systems. Based on the analysis of existing approaches, the peculiarities of using an integrated method of mathematical and computer modelling in order to effective set up and implement a process research experiment are revealed. The logistic system is formalized within the supply of material and technical resources by a centralized method of flow distribution and transfer of management influence from the highest level of the hierarchy to the lower levels such as branches or separate units. Formal identification of the logistic system of supply of material and technical resources is based on the separation of the main factors of the system and the limits of their impact. The main stages of modelling the functioning of logistics processes are specified, which is the basis for clarifying the algorithmic features of the computer experiment. It is stipulated that one of the main approaches to the study of these systems is modelling based on the use of methodological principles of queuing theory, which is based on modelling the flow characteristics of processes, orders and the discipline of their service. The procedure for determining the main characteristics of the system is focused on conducting computer simulations by setting up a computer experiment aimed at simulating the behaviour of the system and its evaluation. Probabilistic estimates of the queuing system are obtained under stationary operating conditions, in the established mode, which achieves limiting the impact of the conditions of the initial state. Emphasis is placed on combining simulation modelling as one of the approaches of computer modelling with elements of optimization solutions that can be obtained as an analytical solution to specific applications of logistics of varying complexity, in particular, inventory management.

In paper there are discussed problems of integration operation determination and definition of primary logical-time functions, characteristic of binary images integration for eye-processor images processing efficiency increasing and possibility of analog signal transformation into discrete numerical expression.

The work highlights the issue of using the modeling method in inventory management of hierarchical logistics systems. The issue of the necessity of inventory management modeling as one of the key parameters of distribution logistics is substantiated. It has been proven that the hierarchical logistics system can generate flow processes according to Poisson’s law, which makes it possible to apply the theory of mass service systems in the formalization of the processes of incoming supplies of resources to replenish the stocks of the logistics center with further distribution of flows among regional branches. This method is based on obtaining optimal characteristics of the intensity of supply of resources in the section of a specific nomenclature, subject to restrictions on available working capital and the formation of a reserve stock for maintenance of repair works.
