The article reflects the results of the study of the created model of the information structure of the system of support. The model allowed to carry out the process of modeling the synthesis of the information system e-learning. A program with a graphical user interface for the synthesis model of the e-learning information system was used for modeling. The program uses the parameters of the hyperconvergent base network and the e-learning system as the input. The result of the synthesis is the optimal placement of users, applications and data blocks by the nodes of the base network. This takes into account the capacity of the system's transactions. This optimizes the capacity of nodes. As a result, the effiency support of the elearning system is increasing. The structure of the hyperconvergent base network e-learning support network is considered as the main factor that affects the quality of the system's requests. Therefore, it is important to analyze the structure when choosing options for building a hyperconvergent base network and its management. The main purpose of the structure analysis is to determine the parameters of the data streams in the network communication channels. The obtained results are necessary for an adequate estimation of network channels and nodes capacity. Data streams form e-learning tasks, which use applications that launch on network nodes and generate network traffic.
The subject matter of the article is an air pollution control process. The aim is development of proposals for the synthesis of the air pollution control system based on hyperconvergent infrastructures. The objectives are: the development of a mathematical model for constructing pollutants concentration fields; substantiation and development of a conceptual model of the geoinformation system for air pollution control, justification and selection of the basic infrastructure of the control system. The methods used are: system analysis of risks, cause-and-effect analysis, statistical methods. The following results are obtained: The basic influencing on character of dispersion and distribution of harmful substances factors in atmosphere are allocated. A multifactorial mathematical model has been developed for constructing fields of concentration of pollutants, which is based on two types of distribution-the normal and S L -distribution of Johnson. The geoinformation technology (GIT) structure components are determined. A program for determining the stability class of the atmosphere has been developed. A model of the process under investigation on a cartographic basis was developed with the presentation of the results in the form of a concentration isotype. The structure of the database of the parameters of sources and characteristics of sources of air pollution, which is part of the serving hyperconvergent infrastructure, has been developed. Conclusion. The synthesized air pollution control system will allow to solve such tasks: collection of primary information, its systematization, analysis and formation of a data bank; processing and presentation of data in the form of thematic pollution maps; Assessment of the current state of the environment and forecast; analysis of the causes of observed and probable changes in the state; prompt provision of necessary information to all stakeholders.
