The article considers the physical processes associated with the propagation of electromagnetic oscillations in a long line, the size of which is the same or slightly greater than the length of the electromagnetic wave (not more than ten times). As a research method, the differential-symbolic method is used, which is applied to the modified equation of the telegraph line. The boundary conditions for the two-point problem as well as additional parameters that are coefficients for the first derivatives in terms of coordinate and time in comparison with the classical equation of the telegraph line are considered as parameters for controlling the process of propagation of electromagnetic oscillations. Based on the differential-symbolic method, the boundary conditions of the two-point problem are found, under which the most characteristic oscillatory processes are realized in a long line. Based on the research, it is possible to draw conclusions about the effectiveness of analytical methods for the analysis of specific technical objects and control of the processes that take place in them.

“…(over 30% of component), along with production curtailment at a range of Russian factories; -Fifth, due to existing problems at the level of radio electronic manufacturers: outdated production and testing facilities, insufficiently rapid introduction of technological advances, a lack of appropriately qualified and trained personnel specialists. (Bobalo et al, 2016). All the identified causes for a reduced quality of Russian communications equipment are due to the general downfall of the country's economy and a sizeable under financing of standardisation, quality maintenance and certification of the products.…”

This paper deals with the problems of industrial products quality in Russia, its control and maintenance. Our analysis of the identified issues is industry-specific: we study how products quality is assured in machine-tool and radio electronics equipment manufacture; some specific features of these processes in defence industry are identified and described. We define the areas where quality management systems can be improved and further developed at machine-tool manufacture plants. We also suggest certain concrete recommendations for developing highly competitive companies that produce radio electronic devices. We propose a system of quality maintenance for defense enterprises. IntroductionCurrently the Russian economy is in a difficult situation. This is facilitated by both a protracted economic crisis and political disagreements between states. The European Union and the United States have applied a package of sanctions against Russia, then additional sanctions restrictions were added in stages, which touched on the most competitive industries: machine-tool building, radio electronic industry, military-industrial complex. Whatever it was, the sanctions to a large extent spurred the efforts of the Russian industry to import substitution, although, of course, led to disruption of the implementation of projects, and somewhere to the rejection of plans.It is important to bear in mind that under the sanctions regime, the share of imports of metalworking equipment from "unfriendly countries", for example, is 63.3% (60.8% of the market); the share of tool imports is 33.3% (30.4% % of the market). This situation leads to negative consequences from the point of view of technological safety.Problems and complexities of Russia's economy manifest themselves not only in stagnation, occasionally in dropping industry outputs and instances of cross-default, but also in the level of quality of products being manufactured. The technology level of equipment and know-how generated in Russia are, sadly more often than not, considerably lower than those in industrially advanced economies (Vershinina et al., 2016). Investments in industrial modernisation and new technologies will be worthwhile only if products to be manufactured are competitive and in demand from customers.The goal of this paper is to present to colleagues our view of the problem of ensuring industrial products quality in a range of manufacturing sectors of Russia's national economy.The presented materials are designed to facilitate professional development of academic personnel and to set the pace for R&D work of young researchers and engineers.
