MODELING THE DYNAMICS OF THE MARKET SYSTEM

abstract 1101506007 issue 110 pp. 111 – 122 30.06.2015 ru 896
In the modern conditions of dynamic development of the market system, the economy, feeling polynomial enthusiasm and recessions, demands external influence, regulation, management. It isn't possible to realize an effective control system of economy without understanding of a consequence. The regulating structure represented by the state needs an effective system of the support of decision-making allowing to estimate the consequences of the made decisions before their direct realization. Use of modern methods of complex estimation for modeling of market system on the basis of trees of criteria and matrixes of convolution allows forming a static market model in the form of the functions of sensitivity interpreted as curves of supply and demand. However, the questions of creation of dynamic market system on the basis of these mechanisms weren't discussed so far. In this article the questions of possibility of modeling of dynamics of the market system built on the basis of mechanisms of complex estimation are discussed. Relevance of the chosen method depends on the possibility of preliminary formation of possible outcomes of an event in the form of the count on definition further of probability of transition to each of states on the basis of a complex assessment of the individual of "advantage" of such transition. An additional benefit of such approach is that fact that when forming market system from some contingent of participants with different behavior models for each of them there is an opportunity to create the scenario, and when receiving at a stage of modeling of result to reconsider the new created structure of structure of society

MODELING THREADS AND THREADED CONNECTIONS IN THE SYSTEM OF THE AUTOMATED DESIGNING

abstract 1321708005 issue 132 pp. 35 – 44 31.10.2017 ru 597
The work was carried out not only in the scientific, but also in practical directions, the key part of which was the modeling of the system. Consideration of the presented modeling processes occurred on the basis of the delivered pedagogical experiment associated with the introduction in the discipline "Engineering Graphics" of a new tool for the military educational institution to obtain the final graphic design document. The purpose of the experiment included a comparative analysis of modeling tools (manual and machine) and their impact on the production of the final product (drawing). As a tool, the computer-aided design system Кompas-3D was used. The presented research was worked out in practical classes of the specified discipline, the theme of one of them was "Image of thread and threaded connections". With the help of the graphic editor Compass-3D, a model of the shaft and bushing with the specified thread profile was obtained, as well as the assembly unit based on them. The entire way of obtaining the above objects for convenience and ease of perception has been broken down into certain stages. The results of the pedagogical experiment were very satisfactory; the goal of the practical training was fully achieved

MODELLING OF OPTICAL PULSE SIGNALS IN QUANTUM CRYPTOGRAPHY COMMUNICATION SYSTEMS

abstract 1231609098 issue 123 pp. 1445 – 1453 30.11.2016 ru 406
It is necessary to know exact value of the full dispersion of waveguides, which leads to broadening and reduction of pulse amplitude for modeling laser radiation passage in quantum cryptography systems. The operation purpose was obtaining of dependences on a wavelength of various dispersion types according to the Sellmeier’ sequationand optical pulse radiation modelling in quantum communication systems. Dependences of the material, waveguide and chromatic dispersions on length of a wave according to the Sellmeier’s equation which allows to consider an optical fiber’s material are received. Distribution of a cryptographic impulse through fiber-optical communication lines of various extent is simulated
