This paper presents two methods of computer simulation (quantum chemical analysis and molecular dynamics) of the interaction of additives with the iron surface. Quantum chemical interaction of silicate and phosphate additives with iron surface was carried out. The plate model was used for quantum chemical analysis, calculations were carried out in the DFT approximation. The method of molecular dynamics is based on the calculation of the evolution of the system of interacting particles of atoms and molecules by integrating the equations of their motion. It is shown that the oxidation of the surface leads to a decrease in the adhesion energy of both individual additives and their combinations, allowing to find the influencing factors on the behavior of tribosystems.

The construction of mathematical models of objects of experimental or computer simulation is associated with the mathematical processing of experimental data. The point dependences of the output variables for the input variables obtained for them are essentially nonlinear, piecewise, sometimes discontinuous. Approximation of such dependencies using polynomial expansions or spline functions is both difficult and involves large errors. A fundamentally new solution to this problem was proposed in the article. This method, called the "Cut-Glue" approximation method, is based on the partitioning of the modeled dependence into sections, the approximation of each section by polynomial dependencies, the multiplicative "excision" from each dependence of the fragments along the boundaries of the plot and the additive "gluing" them together into a single function - the model of the approximated dependence . The analyticity property of the resulting function allows to study the model and use it in models of vehicle dynamics. One of the stages of the "Cut-Glue" method is the "Glue" process - the additive "gluing" of fragments into a single function. For this, an auxiliary multiplicative function is used. The function of this function includes the steepness of the pulse fronts. In this paper, a developed modification of the method of burrowing particles is used in the problem of research and suboptimization of this parameter. As a test bench of the developed algorithm developed a special software tool.

It is proposed to use energy efficiency as a criterion for optimizing of wood fuel production when comparing different technologies with the help of simulation modeling. The results of the calculation of the specific consumption of energy resources per unit of produced fuel chips are considered under the processing technologies under consideration. The costs of energy resources are taken into account starting from the stage of harvesting of low quality fuel wood in the cutting area, ending with shipment of fuel chips to the consumer. The energy efficiency of the considered technological process for the production of fuel chips with the help of a system of machines consisting of an feller buncher, a mobile wood chipper and a chip transport machine accounted for 93.76% with a chip transport distance of 50 km, the energy intensity of the product was 7.949 tons of fuel equivalent for 1 thousand dense cubic meters of fuel chips.

The article considers the application of a modified two-stage genetic algorithm to solve the traveling salesman problem. The traveling salesman problem is a classical combinatorial optimization problem known since 1930. The traveling salesman problem is NP-complex. With the number of cities 66 or more, it is impossible to solve it by exhaustive search. To test the proposed approach to the solution, we consider a graph with 51 vertices from the package TSP_LIB. At the first stage, a modified Goldberg model with small parameter values works to obtain the first generation of the second stage with better performance than the random formation of individuals. The second stage works with increased values of genetic algorithm parameters. These values vary from experiment to experiment, the results of which are presented in diagrams. Also, the results of the two-stage algorithm are compared with the results of the one-stage algorithm. A modified Goldberg model of the genetic algorithm is used. The genetic algorithm uses a waypoint representation of a traveling salesman's route with a two-point ordered crossover and a "greedy" mutation. The experimental results showed the effectiveness of the proposed approach. The modified two-stage algorithm allows to obtain a solution close to the optimal one.

The paper presents a method for decomposition of a complex dynamic system with a network architecture based on the Crohn's diakoptic approach. The proposed method is aimed at the allocation of independent network segments, the removal of which from the general structure will not affect the overall performance of the system. Segments are formed as simple paths in the graph model of the system with the least weight of the incident edges and checking the condition for maintaining the product flow balance in the application to the transport task. In general, the decomposition method presented allows us to divide a complex technical object of the network architecture into subsystems, simplifying the process of analysis and management. In the case when the common control task and the dynamics of interaction of subsystems allow the system to be broken up into unconnected segments, or to limit interaction over certain lines, the method allows reducing the load on the transmitting elements of the system.

Type-2 Fuzzy Logic Controllers do not have the disadvantages of Conventional Fuzzy Logic Controllers, and are widely used in many control areas. However, using it to build embedded systems is accompanied by a large number of rules that increase the processing time and sometimes confusion, reducing the efficiency of the operating system in real time. To eliminate this disadvantage in the paper proposed the new structure of Type- 2 Fuzzy Logic Controller is proposed block based fuzzy controller to reduce the number of rules, and reduce the complexity and increase the reliability of the system control. The proposed controller is based on a fuzzy mass with a small number of fuzzy rules, due to the reduced number of input and output variables. The advantages of the new fuzzy controller are illustrated by the example of the embedded control system of the Self-Balancing Robot. The performance comparison of the proposed block based fuzzy controller shows that the rules of Type-2 Fuzzy Controller is less than twice the number rule of the conventional Type-2 Fuzzy Controller. This increases the yield by 45%, proving the feasibility of the actual application of the proposed controller

This work represents the third article within the cycle devoted to the peculiarities of the analysis of the situations in geopolitically unstable zones of the modern world. This time the author focuses on the second stage of the mentioned scientific procedure. He assumes the analysis of the dynamics of such zones (regions) as multifactorial combinatorics, with the dominance of the conflict nature of interstate relations and the key role (in some cases) of non-regional players. An attempt is made to present unstable regions and the same kind of limitrophic zones as a combination and overlapping of the force fields of a different nature.
