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.

  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.

In article the author considered topicality of statement of budgeting. Theoretical aspects of this process were presented. Defined the stages which are a part of process of budgeting. Also items of expenditure on which it is necessary to pay special attention by drawing up of the budget of the organization were considered. Besides, ways of reduction of expenses on production are offered. In work it was shown how to make the organization budget for a year on «Product Company «Flight of New Technologies» example

The article deals with research problems, tendencies and laws of development of the industry of North Ossetia-Alania. The analysis of industrial production of the region, including the volume of shipped goods of own production, executed works and services by own forces by types of activity: production of minerals, manufacturing industries, production and distribution of electricity, gas and water. The analysis in the dynamics of the трехлетиям the period revealed the presence and size of the negative or positive deviation, as well as levels of stability.

  The article analyses the problem of applying the scientific method of modeling to the investigation of geopolitical processes taking place at the world regional/sub regional “sites”. Preceding from three possible approaches to studying geopolitical dynamics under glocalisation, that is description, formalization and quantification, the author analyses three structural levels of geopolitical modeling. With this purpose in view he analyses the peculiarities and such constituents of its modification as ordinary, conceptual-graphical (cognitive) and mathematical modeling. Special attention is given to conceptual-graphical modeling and its specific language. Admitting the possibilities of using precise mathematical methods and procedures in geopolitics, the author takes into consideration their scantiness. In this respect the validity of mathematical methods and procedures must be provided with quality expert evaluation. The author's message is that the use of heuristic options of modeling in regional geopolitics may serve as the pledge to growing science capacity of this field of knowledge.
