In the article we present a method of cutting logs, containing several quality areas. For this method, a mathematical model was developed to determine the volumetric output of lumber, which allows to determine the geometric dimensions of the lumber cut
from the different quality areas separated concentric circles, depending on size and quality characteristics of logs
The article introduces a study on the creation of a simulated physical and mathematical model of the working process of a strip thrower, throwing soil in a directed flow. The problem solved with the help of this work is aimed at optimizing the cutting and ejection process in a given direction of the soil with minimal energy consumption with a maximum emission range. The article describes a methodology for calculating the milling thrower, which is oriented to the formation of the required amount of soil to create a mineralized strip at the edge of a forest bottom fire. Improving and realizing the full reproduction of physical and mathematical models using process simulations, you can save resources on the development of forestry aggregates. The study presents a productive method of processing soil with milling cutters, which helps to reduce energy consumption due to the formation of oriented mineralized flows of soil. For a physical and mathematical description of the process, a simulation program has been compiled that allows you to test the specific task of minimizing energy consumption at a maximum distance of soil discharge with a constant flow density to the rotational speed of the milling throwers

In the article we investigate the multicriteria task
arising at the organization of distributed calculations
in a corporate network. As a mathematical tool to
solve the problem we use prefractal graphs, which
naturally reflect the structure of relationships in
global and corporate networks. The corporate network
with the distributed computing system at the solution
of a particular task has to be reliable, quickly and
qualitatively to make decisions. And every computer
in the network should be a part in the solution of the
problem, since it is fixed for a certain function. The
problem is reduced to cover the prefractal graphs with
disjoint simple paths along the edges and vertices.
On the set of all admissible coverings we constructed
a vector-target function with specific criteria. All
these criteria have a specific meaningful
interpretation, allowing organizing the calculation of
maximum reliability, with minimum time information
processing and loading balancing between the
network elements. In the article we constructed
polynomial algorithms for finding optimal solutions
according to specific criteria. For the criteria which
are not optimizing the allocated coverings, estimates
of the lower and upper bounds are given. For all the
algorithms we constructed and substantiated
estimation of computational complexity, confirming
the advantage of using algorithms on prefractal
graphs to classical algorithms on graphs

The analysis of mathematical model of the arable unit on the basis of a tractor with EDM in transmission showed that the MTU mathematical model can be considered as working
In the article, we present the mathematical model of a
ventilation system with variable air flow along the
vertical axis of the reactor in the composting process. We
have solved the problem of the choice of the method of
supplying air to the bioreactor, reducing the temperature
of the substrate along the axis of the bioreactor. The
proposed method provides a reduction of temperature
and moisture content of the gas phase, which leads to a
change in the dynamics of the composting process. This
article was prepared in the framework of the scientific
project 16-48-230441 a(R) "Mathematical modeling of
