Аннотация
The relevance of the task of developing methods for forecasting the condition of the tracking object is shown, since the results of its solution affect the quality of its functioning as a whole. A method for forecasting the functional state of an escort object in conditions of behavioral uncertainty is presented, based on a gradient descent in the space of functional states.

Аннотация
An attempt is made to construct a trial Qμ(l) distribution in the silicate shell of Mars. With the allowance for the fact that on the P–T plane the Earth’s geotherm is close to the distribution of areotherms, it was concluded that Qμ(l) should be distributed in the Martian interior topologically close to the Qμ(l) dis- tribution in the Earth. The initial distribution was specified by the four-layer piecewise-constant distribution from the QML9 model. An important step was to select the power index in the frequency dependence of Qμ. Based on the laboratory data and on the experience of studying this problem for the Earth, n was specified in the interval 0.1–0.3. It was found that with the conversion of the initial distribution to the orbital period of Phobos around Mars, which is the only constraint for the problem derived from the observations, this distri- bution agrees reasonably well with the empirical data at n = 0.1.

Аннотация
Regions of maximum tangential and tensile–compressive stresses in the Martian interior have been discovered using two types of models: the elastic model and the model with an elastic lithosphere of var- ied thickness (150–500 km) positioned on top of a weak layer that has partially lost its elastic properties. The weakening is simulated by a ten-fold lower value of the shear modulus down to the core boundary. The numerical simulation applies Green’s functions (load number method) with the step of 1 × 1 grade along lat- itude and longitude down to a depth of 1000 km. The boundary condition is the expansion of the latest data on Martian topography and the gravitational field (model MRO120D) in spherical harmonics up to the degree and order of 90 in relation to the reference surface that is assumed an equilibrium spheroid. The con- sidered double-level compensation model assumes nonequilibrium landforms and density anomalies at the crust–mantle boundary to be the sources of the anomalous gravitational field. Calculations are performed for two test models of Martian internal structure with the crust mean thicknesses of 50 to 100 km and mean den- sity of 2900 kg/m3. Considerable tangential and simultaneously compressive stresses occur under the Tharsis region. The main regions of high tangential and simultaneously tensile stresses are located in the Hellas region crust and in the lithosphere of the following regions: Argyre Planitia, Mare Acidalium, Arcadia Planitia and Valles Marineris. The zone of high maximum tangential and tensile stresses has been found at the boundary between the lithosphere under the Olympus volcano and that under the Elysium rise.

Areas of interest: Mathematical methods of complex systems' structure optimization and their application anywhere: from computer science and chemistry to management and logistics.

Popular digest of the research: 

Are there common laws in the formation of an organic molecule, structuring an organization, or growing a decision tree? Mathematics gives the positive answer! A system is a collection of elements connected with links, which form the structure of the system. Rational structures of natural systems are the result of survival, while the optimal structure of an artificial system must be planned at the design time. Systems science allows catching common properties of very diverse problems in the range from communication network design to business processes enhancement, while combinatorial optimization provides the toolkit of universal solution methods. The clue is the property of locality often met in real life. If the degree of optimality of each element of a structure depends only on how the system is structured in the neighborhood of this element, then the structure can be considered as a chain of braced rings, and the optimal structure design reduces to sequential selection of optimal elements (“rings”) and their optimal connection (but do not forget to care for the desired size and the style of a “chain armor” being sewed!) In the classic Huffman algorithm lying in the core of most archiving utilities an optimal coding tree is built in a bottom-up fashion by sequentially joining the roots of two branches of minimum “weight” under a single node. It can be surprising to get know that organic molecules with the lowest boiling temperature follow the similar formation rule. The same formula is used to calculate both the optimal user menu breadth (the number of options simultaneously available to a user on a screen of his or her iPhone for the most convenient navigation), and the optimal span of control (the number of immediate subordinates) in an efficient organizational structure. 

Many other general laws in complex structure design are revealed during the ongoing long-term fundamental research program. The developed algorithms, routines, and analytical techniques find their application in technology and management.

Аннотация
A closed network consists of several multi-servers with n customers. Service requirements of customers at a multi-server have a common cdf. State parameters of the network: for each multi-server empirical measure of the age of customers being serviced and for the queues the numbers of customers in them, all multiplied by n􀀀1. Our objective: asymptotics of dynamics as n ! 1. The asymptotics of dynamics of a single multi-server and its queue with an arrival process as the number of servers n ! 1 is currently studied by famous scientists K. Ramanan, W. Whitt et al. Presently there are no universal results for general distributions of service requirements—the results are either for continuous or for discrete time ones; the same for the arrival process. We establish the asymptotics for a network in discrete time, find its equilibrium and prove convergence as t ! 1. Motivation for studying such models: they represent call/contact centers and help to construct them effectively.

Consideration was given to the problem of optimal control of a stochastic dynamic system subject to uncontrollable stochastic disturbances. The system is defined over a finite time interval, and its diffusion coefficient depends linearly on the state vector, control signal, and external disturbance. The feedback controller was assumed to be static, nonstationary, and linear in the state vector. A law of optimal control robust to the external disturbance was established.

We consider the H2/H∞-optimal control problem for a dynamical system defined by a linear stochastic Itˆo equation whose drift and diffusion coefficients linearly depend on the state vector, the control signal, and the external disturbance. The optimization is carried out under the a priori requirement of maximum possible damping of the harmful influence of external disturbances on the system operation. We present theorems on the solvability of matrix Riccati differential equations to which the original optimization problem is reduced. DOI: 10.1134/S0012266117030090

Consideration was given to a model containing two coupled autonomous planar subsystems of differential equations. It was assumed that the subsystems admitted families of nondegenerate single-frequency oscillations, and coupling was described by time-periodic functions. Solved was the problem of natural stabilization of system oscillations, where construction of an isolated oscillation and its concurrent stabilization was meant by natural stabilization. Constructive conditions for smooth periodic coupling controls providing problem solution were derived. Specific control was proposed for coupled conservative systems with one degree of freedom.
