Modern radio electronic equipment (REE) in various areas of economic activity performs increasingly complex tasks at sites with increased levels of responsibility. This circumstance increases the dependence of the operation of the REE on the uninterrupted power supply and its quality level, as well as on the level of fault tolerance of an important auxiliary part of the REE - power supply system (PSS), which significantly affects the ability of the REE to perform its tasks. The results of the analysis of existing and search for promising ways to ensure a given level of reliability of REE associated with its power supply problems show the need for an integrated approach to choosing the most effective option. It consists in the cumulative implementation of the process indicated by the newly introduced term «reliability of the power supply chain (PSC) of the REE», combining the continuity of supplying REE with electricity of the established level of quality and trouble-free operation of the PSS performing the conversion of the initial electricity to the form and the values of its parameters acceptable for the power supply of the functional units REE. Ways to improve the reliability of the PSC of the REE of ground stationary objects are considered for two of its characteristic types - a computer system (CS) and a telecommunication system (TS) with a single-phase voltage of 220V; 50Hz and the value of power consumption to 3-5kW. In terms of increasing the continuity of electricity supply, the feature of the proposed solutions is the achievement of the set goal by additional use of existing resources of the facilities of the REE installation. In some cases, their limited increase is also envisaged. In order to increase the fault tolerance, the PSS REA suggests: in the centralized part of the PSS - the application of the trunk-modular architecture, the choice of the effective structure, and also the adaptive methods and algorithms for management and redundancy, in the distributed part of the PSS - optimization of the structure and minimization of the number of constituent parts.

This paper is addressing the issues regarding formation of authorized supply chains in international trade with reference to the World Customs Organization (WCO) standards and specific aspects of customs administration. The paper is evaluating the WCO imperatives and modern information technologies used in the sphere of customs risks management. It is defining the weak points of international China to Russia supply chains. It is substantiating the necessity to make analytical assessment of evolution of institute of authorized economic operators in China and in the RF. The paper brings to light particular features of institute of authorized economic operators in China and defines directions of its further development. It is evaluating specificity of evolution of institute of authorized economic operators in the RF under the conditions of customs regulations harmonization in Eurasian economic Union (EAEU). It was noted that innovation of the EAEU customs' Code consists in possibility to issue three types of certificates which are verifying party's incorporating into the Register of authorized economic operators and (2) differentiation of special simplifications depending on the type of a certificate.
