  The article is devoted to the problem of the research of geopolitical processes on the world regions’ scale under present-day conditions. The article substantiates the necessity of their analysis with the help of the cognitive approach as an effective means of cognition of the interconnections and interrelationships within the complicated systems. With that aim in view the specifics and the stages of the cognitive modeling are given thorough analysis in the article. This type of modeling is adapted to the analysis of geopolitical dynamics on the regional/sub regional level taking into consideration its aptitudes to make prognostic scenarios of the development of the situation. The possibilities of the cognitive modeling of geopolitical processes are illustrated on the example of the situation in three sub regions constituting one (big) the Black Sea – Caspian region.

Keywords: World regions, geopolitical processes, modeling of the complicated systems, modeling of the geopolitical processes, cognitive modeling, the program’s system of the cognitive modeling, the Black Sea – Caspian Region, the Black Sea sub region, the Caucasus

After accession of Russia into the WTO the tasks related to the development of infrastructure have been sharpen. With the growing volume of cargo traffic and the lack of opportunity for the extensive development of the port infrastructure, the alternative of building the dry port can be only feasible, although explicitly the most expensive. Due to this reason the method of gradual development of the dry port which provides significant economic efficiency was addressed in the article.

Keywords: dry ports, net present value, the efficiency of the investments

Work is devoted mathematical modelling of processes in the channel of the MHD-device with the conical axisymmetric form of a channel. The assumptions accepted at modelling are formulated. The mathematical description of a prototype system with usage of known laws of electrodynamics is conducted. The equations of components of density of current, a magnetic field and electromagnetic forces in the conical part of the channel of the observed device are defined. Adequacy of the developed model is confirm by results of computer simulation of processes in the channel of the device. Deductions about applicability of results of the given work are presented.

Keywords: MHD-device, conical axisymmetric channel, density of current in the channel, mathematical model, electromagnetic forces

The numerical algorithm consists of in determination of a minimum of some functional, defined in the area containing in advance unknown interface. The unknown interface is obtained from a minimization condition of the functional together with unknown functions. The problem for plane area dares a method of grids.

  Structural changes in cumulative labor displace the purposes of social development and generate understanding of that the economy exists for the person, and people – the main value of modern society. The evolution of the term tracked in article the sociolabor relations, consideration of elements, levels and the purposes of the sociolabor relations, the characteristic of types of regulation of the sociolabor relations and an assessment of system of the sociolabor relations of Russia allowed to add definitions of the sociolabor relations by concept «the human capital» and to define system of the sociolabor relations of market economy as a complex of relationship concerning development and effective use of the human capital.

Decision making in the organizational and technical systems is complicated by the risk of various events emergence in the systems with a given probability. The article describes a method for supporting decision making under risk on the basis of integration of evolutionary, multi-agent, simulation models and numerical methods. In the course of the method's work the following steps are performing: a set of alternatives solutions is formed;  transition to a one-criterion alternatives evaluation is fulfilled by using linear convolution; transition to the system behavior certainty is fulfilled with the use of numerical optimization Bayes-Laplace criterion. The developed method is applied to solving the projects scheduling problem; the results agree with the problem solution that has been performed by using genetic algorithm method under certainty.

Keywords: decision making risks, multi-agent modeling, numerical methods of decisions optimization, scheduling problem, evolutionary modeling
