  Mathematical Theory of Estimation of Contribution of Scientist to Science
• Abstract
  • Relevance. In recent years, increasing attention of power structures and the scientific community has acquired quantitative methods for assessing the effectiveness of scientific research, in connection with the need for adequate funding of science. For the technological support of this area of work, new mathematical models and methods of introducing and calculating quantitative indicators of the effectiveness of scientific research are important. In this regard, this article on the development of such models and methods is relevant. The purpose of the article is to develop several new models that allow us to introduce a number of new indicators of scientific research using information about the scientist's publications and his quotations. Method. To achieve this goal it was proposed to use the distribution of citations in the form of a graph as the initial data, along the abscissa of which the publications of the scientist are arranged in order of increasing of citations and along the ordinate axis the corresponding quantities of citations are pointed. The graphs of the distribution of citations are convenient for the introduction of new indicators of the effectiveness of research by scientists and their analysis. Novelty of the work lies in the proposed two universal methods for quantifying the effectiveness of scientist's scientific research on the basis of its citation distribution schedules: a measuring method that reduces this estimate to a comparison of scientist's citation distribution with the citation distribution of a hypothetical single scientist, and the method of moments reducing this estimate to the computation of moment (of suitable order) of citations distribution of the scientist. Result. In the article a mathematical model and methods are developed in detail for the introduction of new indicators of the effectiveness of scientific research, their analysis and calculations.

The novelty of the model is to take into account the capabilities of monitoring, capturing and locking of information resources in the dynamics process of development of information conflict. Results. The result of the research by model is to identify several of the typical states of conflict and the bifurcation points where conflict changes its state. In bifurcation point one of the conflicting parties can change the development trajectory of the conflict and so this party will have possibility to win. The action scenarios of one of the parties to achieve wining in the conflict are based on the research by model. A typical scenario of action for one of the parties was analyzed, to determine the most "strong" parameters of this party, and the change directions the parameters to ensure wining. Practical significance. The model of informational conflict can be used a large number of conflicts between the real information-technology systems in several areas.

  Flexible Service Model of Complex Traffic and Real-time Algorithm of Channel Reserve for Satellite Earth Stations
• Abstract
  • Relevance. At present, there is a high demand on services transmitting a multimedia content, telephone and video communications and transferring data which can be satisfied by using satellite networks in certain cases. The traffic load created at the same time generally has a complex structure. The coverage of servicing areas of satellite networks, on the one hand, and the principal scarcity of the orbital radio resource, on the other hand, require online radio resource management in order to increase its use efficiency. One of the ways to improve the radio resource use efficiency is multiplexing satellite radio lines taking into account the statistical characteristics of the relayed traffic and the operating modes of the satellite modem. The paper purpose is to develop the model of the flexible service of the complex structure traffic and an real-time algorithm of channels reserve in the earth stations through variation of the traffic received from various subscribers of the earth station which allows to improve the radio resource use efficiency (the capacity expressed in the number of available channels) of the satellite communication network by means of online backup of the channel radio resource. Results. The searching of backup channels is defined as a non-linear programming task, as well as the example how to resolve it while servicing the complex structure traffic created by a group of subscribers is provided. The novelty of the approach is that a new model of the flexible service of the complex structure traffic provided by the earth station different from the known ones due to taking into account the dynamics of the capacity change when switching between the operating modes of the modem equipment is developed. The developed model as a four-dimensional Markov chain was obtained on the basis of the state space extension using models of the configuration change of the modem equipment, of the group source of the complex structure traffic, of channel resource backup with time delay, as well as of the service process of the single channel system traffic. The assumptions concerning the exponential laws of distribution of duration of subscribers’ activity and pauses, delay in connecting to an auxiliary channel resource, duration of transferring individual communications, and intervals between them, as well as time interval sizes for the readjustment of the modem equipment are adopted as limitations. The algorithm different from the known ones due to taking into account the current allocation of the channel resource is proposed on the basis of the developed model and allows to find an optimal moment of the auxiliary channel connection in case of a significant increase in the power of a set of alternatives. An example how to complete the set task is provided. Practical significance. The total results obtained as a model of the flexible service of the complex structure traffic and as the algorithm will allow increasing the capacity of the satellite communication network by 10-40% while ensuring the specified quality of the subscribers' service.

  The Organization of Adaptive Multiplexing of a Traffic of Multiservice Networks in the Channeling Equipment of Land Satellite Communication System with Taking into Account the Changing Jamming Situation
• Abstract
  • Relevance. The increasing volumes of the transmitted data at high quality requirements of service and limitation of a radio resource of the spacecraft of communication do urgent questions of ensuring high bandwidth of land satellite communication system in the conditions of dynamically changing jamming situation. At implementation of the existing technologies of multiplexing of a traffic in the channeling equipment of land satellite communication system selection of a radio resource happens under peak values of intensity of information flows, without its statistical characteristics that is expressed in underexploitation of a radio resource at its general deficit. The paper purpose is consists in capacity growth of land satellite communication system in the conditions of an jamming situation. For achievement of the goal it is offered to use technology of adaptive multiplexing of a traffic which will consider its statistical characteristics, in different conditions of an jamming situation. It will allow to increase bandwidth of land satellite communication system and to fulfill quality requirements of service of a multiservice traffic. The used methods. The solution of a task of the organization of operational management of a multiservice traffic at adaptive multiplexing in the channeling equipment of land satellite communication system is based on use of Markov models of the modulated Poisson process and algorithms applied in the teletraffic theory taking into account specifics of functioning of communication satellite networks. For a research of the developed models the calculation procedure realized in the software package of mathematical modeling of MatLab is used. Novelty. Elements of scientific novelty of work are the accounting of a number of factors: properties of the arriving multiservice traffic, such, as, not stationarity, heterogeneity, priority in service, fulfillment of requirements on service quality and existence of the different modes of functioning of satellite radio lines which depend on conditions of an jamming situation. Result. Use of technology of adaptive multiplexing in combination with the mechanism of dynamic purpose of priorities in service of a multiservice traffic allows to increase considerably number of communication links in comparison with the existing technology that corresponds to capacity growth of land satellite communication system or ensuring required bandwidth in the conditions of an jamming situation. At the same time it is worth canceling that capacity growth will depend on requirements imposed to service quality, a type of the transferred traffic, and also the choice of an operation mode of the modem equipment. So, at the most strict requirements to service quality the prize will make up to 40%, at less tough (an unlimited admissible delay) extremely achievable values will make up to 120% that averages about 80%. Practical significance. The submitted decision is offered to be realized in the form of special program software of the channeling equipment on the basis of a program and modular platform which has to be integrated into structure of an automated control system of the terrestrial station of satellite communication. Implementation on the basis of a program and modular platform will allow to exercise on the basis of the analysis of statistical properties of a multiservice traffic its operational management at adaptive multiplexing in the conditions of the changing jamming situation, by assignment to information flows of priorities in service.

These technologies are widely used in engineering, economics, social sphere. To support them, new mathematical models and methods are needed. In this regard, this article, devoted to the development of a new model of uncertainty (poly-interval) and mathematical methods for its study, as applied to solving optimization problems under uncertainty, is topical.

Necessary and sufficient conditions for the existence of these operations are established, i.e. conditions for the comparability of polyintervals. An example of using the results obtained for making optimal decisions is given.
