The paper considers the problems of organizing an information survey, as the initial stage of creating an automated control sys-tem. This stage is most important in the development of automated control systems. It should provide a description of the analy-sis of an information and functional content of existing management processes in the form of a functioning model of the organ-izational and technical system under consideration. Such description should contain a system of detailed structured descriptions of all functional subsystems, processes, functions and tasks of officials of the automated system, as well as a description of a composition, content, circulation and requirements for processing documents in each automated process. The developed func-tional model provides the initial level of formalized descriptions of the considered processes, which presents and correlates with time all tasks and related documents. It should be a basis of forming a management process information model containing the combined, harmonized and standardized presentation of data required for all categories of officers of the organizational and technical system. According to domain analysis, the initial stage of creating a system (research and development rationale) is for setting the basic parameters of its further development. Existing approaches to the informational survey, which are focused on paper-and-pencil technologies, do not provide the proper quality of the formation of an automated system information model and a relia-ble basis for further work. At the same time, there is a fairly wide range of tools and methods to ensure the development of management automation tools, including tools for creating functional and information models. The paper proposes ways to solve the problem of the information survey of an automation object by consistently constructing a functional and information model of an organizational and technical system using the capabilities of modern information technologies. The paper proposes to finalize regulatory documents on the development of automated control systems for the implementa-tion of the proposed principles. In particular, taking into account another important factor in the process of management auto-mation – the mutual influence of the control system structure and automation tools introduced into it. As the practical experi-ence shows that these measures can significantly improve the efficiency of automated systems development.

The papers considers the function hierarchy of data storage at a physical level. At the first level, there are functions to maintain a steady state of minimum data storage units. The number of stable states of data storage minimum unit affects the number of stored data bits. It is shown that minimum data storage units differ depending on the file type and the medium type. There is an expression that allows estimating the minimum energy required to convert a minimum storage unit. At the second level, there are functions to combine the minimum units of data storage into physical data blocks. The paper shows the structure of a physical unit. There is an example of changing a physical block size. It demonstrates the possibility of adjusting a physical block size depending on the stored information type and requirements for the storage system. When a phys-ical block increases, the metadata stored in a medium decreases, and thus the efficiency of using the media capacity increases. At the third level, there are functions to unite the physical blocks into logical data blocks. The logical block size depends on the capabilities of the installed file system and is set when formatting. At the file level, there is addressing of data bits, physical and logical blocks, thereby the data bits are logically combined into a file. The paper presents the results that demonstrate a sig-nificant reduction in energy consumption with a data block size increase and a metadata volume decrease compared to energy consumption when maintaining the original file.

The paper proposes a solution for the problem of automated control of the aluminum waveguide paths induction soldering pro-cess based on two control loops with the work position shift. Within the work, the authors analyze the features of technological process of aluminum waveguide paths induction soldering. The analysis shows the necessity of the process automation using a software system. The developed software product controls the product heating process in two circuits. The first circuit is the control of the waveguide path elements heating rate. The second circuit is the control of the waveguide assembly movement relating to the in-ductor plane. The developed automated system provides high-quality control of the induction soldering technological process, and consequently, reduces the number of menders. The software solution is an application for the Windows operating system that is compatible with Windows XP/7/8/8.1/10. The application is developed using C ++ and the Embarcadero RAD Studio XE7. The development included an object-oriented approach. The paper shows the automated system structure, its operation algorithm, as well as the diagram of the screen forms transi-tions. The design process includes building use-case and state-chart diagrams using the UML language. The presented software solution contains the functionality of adjusting measuring instruments and the parameters of the induction soldering technologi-cal process. In addition, it is possible to view the product parts temperature graphs. It is possible to view and edit the database of technological processes. The approbation of the solution was carried out within the framework of a series of experiments that have shown high-quality control of the induction soldering technological process.

The paper considers the problem of software development of a measuring system for operative spectral analysis. The software development includes a modular paradigm for organizing software components. It allows ensuring flexibility and extensibility of the system, development process scalability, interchangeability of software components and the possibility of their reuse. According to the chosen approach, the visualization system software consists of a module of a spectral analysis algorithm, a module for measuring data visualization, and a data processing converter that provides communication between these modules. The software structure is based on a multi-level organization of the computing environment. The levels of data representation and processing are highlighted. This allows separating metrologically significant and insignificant parts and protecting measuring information against unintentional and deliberate changes. The presentation level is implemented in Java, and the processing lev-el is in C++. The choice of Java is due to the availability of support components for digital display technologies and user inter-face, which made it possible to make the application functionally flexible in use, to manage the spectral analysis process includ-ing data entry operations, graphical and tabular visualization of results. The procedures of calculating spectral estimates are implemented in the metrologically significant software module in C++, which enable multithreaded programming to improve data processing performance during the spectral analysis.
