Digital management by supply networks in engineering

Abstract

Current Mechanical Engineering Production has a complicated network structure for technological processes providing. Equipment digitization of material transition allows you to get a real-time slice of economically important indicators. Also, the whole dynamics of production functionality can be presented in the formal view by mathematical models. The article deals with transference processes in linear commercial networks, which are network-like diffusive phenomena described by classical equations of mathematical physics. In addition, many problems of mathematical physics lead to the necessity to define coefficients in the partial differential equation and coefficients in boundary conditions with known functionals from the solution of the matching initial - boundary value problem. In case of depending coefficients in the differential equation on a spatial variable, the real presentation of the solution makes it impossible to define these coefficients. Therefore, other approaches, in particular, spectral ones figure in this article.

Optimizing the energy efficiency of higher education institutions

“…n n W  − relevant characteristics n-th room used in the educational process, research activities [28] for administrative and engineering purposes. However, since the optimization problem requires relative values rather than absolute values [29], the problem is simplified and the desired characteristics can be obtained by examining the premises using time slices of temperatures determined by digital sensors, followed by processing on a computer [30]. Figure 1,2 shows the results of computer simulation of the process of changing the temperature in the room.…”

Solving the problem of energy efficiency of remote agricultural farms

“…To maintain effective interaction with rural agribusiness entities, it is necessary to adapt their algorithms [24] and software [25] to the specific conditions of such business. When setting the task, it is necessary to take into account the statistics that show that in the Russian Federation, the area of crops and livestock are constantly decreasing.…”
