Документ Research and analysisindicatorsfiber-optic communication lines using spectral technologies(Національний технічний університет "Харківський політехнічний інститут", 2022) Ibrаhimov, Bayram; Hashimov, Elshan; Talibov, Aziz; Hasanov, ArifThe fiber-optic communication linesand fiber-optic transmission systems using fiber-optic cable, receiving and transmitting optical modules based on WDM and DWDM (Wavelength Division Multiplexing & Dense WDM) technologies are studied. A method for calculating thetransmission characteristicsfiber-optic communication lines is proposed and relationships are obtained that establish an analytical relationship between the length regeneration section and the transmission rate. This paper discusses the study and analysis indicatorsfiber-optic communication lines using spectral WDM and DWDM technologies.Документ A method for assessing the military-economic indicators with the purpose of locating a logistics center for redeploying troops(Національний технічний університет "Харківський політехнічний інститут", 2021) Talibov, Aziz Mashalla; Guliyev, Bakhtiyar VagifThe article proposes a methodology for assessing the economic efficiency of a logistics center that provides technical support to redeploying troops. It is noted that the development of this method is based on the assessment of the efficiency of the logistics center, taking into account its economically efficient functionality, without regard to the use of classical profitability. The author analyzes the structure of capital expenditure and operating expenses allocated for the establishment of a logistics center, proposing the maintenance and repair expenses for each unit of equipment as the main criterion, proposing their calculation in the general case, and substantiating the military-economic indicators of the center. An analysis of the structure of capital expenditure and operating expenses aimed at organizing a logistics center, as well as the military-economic indicators of this center, gives grounds to note the following results: the structure of capital expenditure and operating expenses associated with designing a logistics center for the troops has been elaborated; the calculation method has been developed, taking into account the available resources, communications and infrastructure, information reflected in the annual plans for the operation and maintenance of automotive and armored vehicles of military units; the calculation methodology developed on the basis of the structure of capital expenditure and operating expenses on the organization of a logistics center also reflects the infrastructure indicators related to the geographic location of the center (the distance of the logistics center from the transport hub and the military units it services); the proposed method can be used to choose a geographic location that is favorable from the point of view of economic profitability for organizing a logistics center for the troops; using this method, it is possible to compare the economic aspects of various options of organizing military logistics.
