  • The study of dynamics and determination of the directions of development of the industry of the region

    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.
     

    Keywords: industry, sector, region, the economy, the gross regional product, industrial production.

  • The modelling of tne geopolitical processes in the world regions under glocalization and its structural levels

      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.

    Keywords: geopolitics, world region/sub region, glocalization, situation analysis, mapping, map, modeling, modeling of the geopolitical processes, usual (simple) geopolitical modeling, conceptual-graphical (cognitive) mapping, graph
