Документ Method of assessment of the efficiency of the communication of operational troop grouping system(Національний технічний університет "Харківський політехнічний інститут", 2020) Shyshatskyi, A.; Suhak, S.; Tiurnikov, M.; Lyashenko, A.; Bokhno, T.; Bondar, O.; Melnyk, A.The most distinctive features of military communications systems are the high degree of a priori uncertainty about the operational situation and the small amount of source data for communications planning. In such circumstances, it is important to make the right decision-making appraisal apparatus, which will allow the officials of the system management bodies to be confident in the decisions made. Deciding to build a communications system at any level usually involves defining the purpose of its operation, selecting metrics and justifying the evaluation criteria, synthesizing alternative structures, and finding a rational option for deploying the communications system. The practice of the troops has convincingly shown that in the theory and practice of communications, there is a need to improve the scientific and methodological apparatus, which will meet the current conditions of operation of control systems and provide a more adequate assessment of the effectiveness of deployable communications systems. In this article, the authors propose a method for evaluating the effectiveness of the communication system of the operational troop grouping. The above method is based on the first time use of the communication system accessibility indicator. In the course of this research, the authors used the basic principles of communication theory, noise immunity theory and intelligence. The novelty of the proposed method is that the communication system operational troops grouping are estimated by generalized indicator of availability of channel resources and network communications system of the operational troops grouping. The practical value of the proposed methodology is that the methodology allows for a more accurate assessment of the communications system, the identification of deployment arrangements and measures to improve the effectiveness of the operational troops grouping.Документ Generalized indicator of the effectiveness evaluation of military radiocommunication systems(Національний технічний університет "Харківський політехнічний інститут", 2018) Tiurnikov, M.; Shyshatskyi, A.; Mikus, S.; Mishchenko, A.Modern military radiocommunication systems are working in the difficult conditions due to the shortage of radio frequency resources, limited computing resources and the influence of the enemy radio-electronic suppression devices. One of the ways to increase the noise immunity of military radiocommunication systems is to develop effective indicators, algorithms and methods for assessing the state of military radiocommunication systems. Nowadays, a large number of indicators for evaluating their effectiveness have been developed to evaluate military radiosystems, but their application is due to a number of limitations, that indicators with high precision are generally not used due to their high computational complexity, and those indicators having an acceptable computational complexity have low accuracy of evaluation. Therefore, in order to increase the protection of the security of military radio communication systems in the article, the authors developed a generalized indicator of the evaluation of the effectiveness of military radiocommunication systems. During the research, the authors of the article used the basic provisions of the theory of communication, mathematical statistics, management theory and the theory of tampering. The generalized indicator of the evaluation of the effectiveness of military radiocommunication systems developed in the work, allows to increase the noise immunity of military radiocommunication systems by increasing the speed of their state assessment. The carried out estimation of efficiency of the developed indicator allows to assert about its raisingon 15-22% efficiency in comparison with classical indices of power and spectral efficiency of systems of military radio communication. The practical significance of the research is the possibility of using the proposed generalized indicator of the evaluation of effectiveness in developing new and modernizing existing military radiocommunication facilities (radio monitoring centers).
