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.

In this paper we consider the problem of effective forecasting of electricity consumption for multiple objects in automatic mode. We propose an approach to automation of forecasting process, based on CRISP-DM. There were considered methods of computational intelligence for the data preprocessing - filling the gaps and identification of the emission, methods of construction and adjustment of forecasting models. As the computational basis are used connective models, based on neural networks and on constructive neural networks. There was shown the system architecture that implements the mechanisms of computational intelligence, and was presented the results of the tests.
Keywords: consumption of electricity, forecasting automation, computational intelligence, identification of the emission, connective models.
Considered sharing FEM and BEM for the calculation of the dynamic behavior of the surface structures on the basis of a multilayer. To implement the BEM in calculating base proposed analytical method is effective for an arbitrary number of layers and the relations of their parameters. Given system approximating functions in the interface methods and proposed numerical integration formulas on the mating elements.
Keywords: finite element method, boundary element method, laminated base, fundamental solutions.

In the framework of the nonlinear buckling considered the problem of determining the critical pressure, distributed over the face of the cylindrical shell. Buckling criterion is the appearance of positive acceleration directed along the normal to the middle surface of the shell. Numerical solution of the system implemented in MathCAD. Given its comparative analysis with the known solution formula Papkovich.
Keywords: cylindrical shell, nonlinear stability, numerical solution, the system MathCAD.
