    Subsystem of CPS information support organization
    (Lviv Politechnic Publishing House, 2018-02-01) Hirniak, Yurii; Ivakhiv, Orest; Nakonechnyi, Markiyan; Velgan, Roman; Viter, Oleksandr; Lviv Polytechnic National University
    The possibilities of the information support for cyber-physical designing systems have been considered. Their coincidence with Open System Interconnection Standard has been analyzed. Their effectiveness has been taken into account. From this point of view, the usage of compression technique, low-energy wireless networks has been considered.

    Research and design of the multifunctional cyber-physical system of testing computer performance in WAN
    (Lviv Politechnic Publishing House, 2019-02-26) Pasternak, Iryna; Lviv Polytechnic National University
    A multifunctional cyber-physical system for monitoring and testing remote computers in the WAN has been developed. This cyber-physical system has been built using microservice architecture. The system has used a website as a graphical interface, which in turn communicates with the main query separator, namely a web server. In addition, the database and the AES-256 encryption algorithm has been used to simplify data work, and to increase system security from external interventions. The algorithms of processing requests, algorithms of checking the efficiency of different modules of the computing node have been developed. A system of internal communication has been designed. The links between database tables have been designed. The utilities for various custom actions have been developed. The user has also provided the ability to group users and computing nodes to simplify the process of analyzing data on the performance check.

    Principles of cyber-physical systems construction for the needs of crops cultivation
    (Lviv Politechnic Publishing House, 2017-02-01) Vanko, Volodymyr; Lviv Polytechnic National University
    On the basis of the hierarchical structure of a typical cyber-physical system and main stages of crops cultivation, the list of the subsystems necessary for the creation of such a system is considered. The structures and recommendations for these systems are expounded, and the generalized structural scheme of the given cyber-physical system is described issuing from the four main objects of the research: seeding material, soil, intermediate harvest benefits, harvesting, stocking or primary processing. The application of the matrix method for the assessment of production processes quality as well as final products, which is realized at different hierarchical levels of a cyberphysical system, is proposed. The approach to the analysis of system functioning at all stages of crops cultivation is represented. The principles of data matrices forming at hierarchical levels of a cyber-physical system in combination with the applied subsystem types are presented.

    Digital interfaces in cyber-physical systems
    (Lviv Politechnic Publishing House, 2017-02-01) Grebeniak, Andrii; Miyushkovych, Eugene; Paramud, Yaroslav; Lviv Polytechnic National University
    The analysis of structural solutions of autonomous measuring-computing nodes (AMCN) Ethernet – oriented cyber-physical systems (CPS) have been conducted. The possibility of using the standard industrial sensors and actuators with low-speed serial ports in them have been showned. General basis of telecommunication subsystems has been given. The basic options of realization of telecommunications subsystems have been proposed and the recommendations about choosing a concrete decision by the criterion of necessary computing power for primary data processing. The physical model of telecommunication subsystems has been investigated.

    Satellite scientific data collection and accumulation system as a basis for cyber-physical systems construction
    (Publishing House of Lviv Polytechnic National University, 2016) Hlukhov, Valerii; Lukenyuk, Adolf; Shenderuk, Sergii; Lviv Polytechnic National University; Lviv Centre of Institute for Space Research of National Academy of Sciences and the State Space Agency of Ukraine
    The paper reviews technologies of computer systems the development of which has led to the emergence of cyber-physical systems – there are embedded computer systems, open systems interconnection model, multilayer computer systems, wireless communications, microelectromechanical systems, data protection technologies. It is noted that there are computer systems exist, whose parameters are close to those of cyber-physical systems ones, there are also groups of developers who have experience of in such systems designing. The satellite scientific data collection and accumulation system developed in Lviv Center of Institute for Space Research of NAS and SSA of Ukraine with the participation of Lviv Polytechnic National University Computers department is an example of such systems. In paper The main features of this system are described in the paper. The recommendations are given onf using it as the basis for the creation of advanced cyber-physical systems.

    Security of cyber-physical systems from concept to complex information security system
    (Publishing House of Lviv Polytechnic National University, 2016) Dudykevych, Valerii; Mykytyn, Galyna; Kret, Taras; Rebets, Andrii; Lviv Polytechnic National University
    A conception of multilevel complex security system (CSS) of cyber-physical systems (CPS) was developed; dimensional model of information-technology state (ITS) was proposed; informational model of CSS cyber-physical system “iPhone – Wi-Fi, Bluetooth – sensors” was created; software of symmetric block data encryption of “Kalyna” algorithm was realized.
