In the article is discussed the optimization of color perception process of printed products by the method of steep climbing in Box-Wilson. There are presented results of experiment planning and statistical modeling of the process of color perception with the offset printing method on paper, including synthetic polymers. It is presented a mathematical model of the color perception by the Box-Wilson steep ascent method, it is achieved the optimum range for the response function in the form of the paint layer thickness depending on the pressing force (pressure), the pressing process speed and paper smoothness. As a result, on the basis of the obtained color perception model, optimal parameters were established, which allow to hold objective assessment and prediction of the color perception of the printed materials. The results of the study are the basis for the rational determination of the compositional composition of the experimental paper in its design and development of both paper and printing products.

The article presents the results of solving the problem of attenuation of an optical signal in fiber-optic communication lines. Widely used modern technical solutions of intermediate amplification-regenerative nodes of fiber-optic communication lines are described. The advantages and disadvantages of existing intermediate fiber optic amplifiers are presented. The benefits of optoelectronic signal regenerators include a full restoration of the original properties of the optical signal. The optoelectronic regenerator allows to limiting the amount of internal and external optical noise by acceptable values, but increases and increases the cost of building optical fiber connections.Optical signal amplifiers are also used to increase the range of fiberoptic communication lines. The main advantage of intermediate fiber optic amplifiers is their relatively simple design and, consequently, low cost, as well as high cost of losses and power output.The technical function of the developed fiber optic amplifier is to create a signal and power amplifier that is evenly distributed inside the fiber located in the region of the fiber containing the fluorescent additive.The characteristics, functional and structural diagrams of an optical repeater with erbium amplifiersare shown in detail. The design features of the construction and the principle of operation of the erbium amplifier are described.

The article discusses the issues of finding the main indicators of the quality of the communication channel in computer networks when transmitting priority and non-priority data at different frame lengths. To solve this problem, methods of the theory of queuing using Petri nets are proposed. The proposed method for calculating the temporal and probabilistic characteristics of computer networks allows determinining the main indicators of the quality of the channel in a stationary mode when transmitting priority and non-priority data of computing tools at various values of the input stream intensity. To simulate the transmission of priority and non-priority frames, a color temporary Petri net is proposed. An algorithm is proposed for determining the basic parameters of information transfer, based on the use of the Little formula and allowing one to determine the number of frames in a queue, the average time a frame has been in a queue, and other distinctive features of the algorithm include the use of the window mode. The proposed technique allows to reduce the loss of priority frames of trajectory information and ensuring their transmission in real time.

Electricity consumption regulation is the primary technical basis for energy consumption planning. Electricity consumption is regulated in the form of specific electricity consumption per unit of production or per unit of work performed. Specific energy consumption rate is understood as the consumption of electricity necessary and sufficient to produce a unit of production or to perform a unit of work in the planned conditions of production and operation. Electricity saving takes place if its actual specific consumption is comparable with progressive norms developed on the basis of introduction of new equipment and technology into production, rational operation of technological equipment and electrical installations. One of the main directions of improvement of rationing is the choice of rationing structure taking into account the objective assessment of actual energy resources saving. The article shows the rationing of electricity consumption in the production of finished products at the enterprises of ferrous metallurgy, in particular, at the electric steelmaking industry. The results of the analysis of the state of electricity consumption rationing in the ferrous metallurgy industry are given. The developed multilevel structure of electricity consumption rationing based on the results of the study, which gives the prospects of determining the possibility of energy saving at the object under consideration, is described.

The task of determining specific electricity consumption is complex, as it is necessary to take into account a large number of factors affecting the energy indicators that determine the level of these indicators. At the same time, the type and technical condition of the main and auxiliary process equipment in the process of melting, the nomenclature of metal, the volume of consumed components of the process and secondary energy carriers (compressed air, nitrogen, oxygen and other auxiliary components), etc. are taken into account. The error in taking these factors into account may lead to deviations from the actual values of the predicted power consumption, as well as energy indicators. The energy intensity of products and the level of energy consumption also depends on changes in the structure of energy consumption, the latter depending on the need for such process components as compressed air, oxygen, nitrogen, etc. The article considers the results of the analysis of energy indicators of enterprises of ferrous metallurgy, in particular, electrosmelting shop by types of output products on the basis of decomposition scheme. It is shown that the set task is solved by means of construction of dependences of normative energy characteristics on the volume of output products, and also the final decomposition tree is formed - the tree of tasks designed to achieve solutions of energy problems, including the main one - to obtain the value of specific energy consumption. In addition, the article presents the method of determining the share of participation of auxiliary components of the technological process for example of compressed air, nitrogen and oxygen. At calculations the account of the above-stated components gives the chance to define more precisely specific expense of the electric power.
