  • Marketing strategy: features in services complex of the region (on the example of the Rostov region)

    In article it is briefly considered stages of formation of definition of strategic marketing in scientific literature of Russia. The importance of a services sector in economy and the importance of modernization of the given sphere for the general development of economy as a whole locates. The analysis of dynamics of paid services to the population that will allow to reveal the sphere of servants with the greatest volume of consumption among the population is carried out. Are considered the sphere of transport services of the Rostov region, as a result of research SWOT analysis of marketing strategy is carried out to projections to the sphere of transport services of the Rostov region and recommendations to transport companies of the Rostov region for a choice of suitable marketing strategy are made.

    Keywords: diversification of management, production diversification, financial and economic purposes of a diversification, technological purposes of ensuring flexibility of production

  • Solution of one-criterion optimization problem of crew actions scheduling on Russian segment of International space station

    The flight scheduling process is briefly described in the article. It is one of the most important stages of space flight control task solution. Three stages of flight scheduling are given: strategic, tactical and executive. The result of each scheduling phase is presented by special plan type: on-orbit operation summary, weekly lookahead plan, short-term plan. The difference of these plan types is in planning interval and data processing depth. The mathematical modeling of all required data and restrictions is made. A crew downtime minimization is the selected optimization criterion. Modified genetic algorithm for decision of assigned task is designed. The future tasks regarding crew activities scheduling process optimization are defined

  • Silent interval detection in speech signals

    A voice activity detector (VAD) is a device, which analyses a speech signal and generates the signal corresponding to the period containing only noise. In the present work is offered VAD, which increases the probability of correct detection the presence or absence of human speech.
    The correct detection begins with SNR 7-10 dB. The quality of  derived speech signal remains the same.

  • Model of integration of construction production

    Now development of the administrative principles is directed on selection of the corresponding forms of total activity of employees of the investment and construction sphere. The methodology of a point of profitability shows, how many production the organization has to realize to refund the expenses. We offer model of management of integration in construction, using the mathematico-statistical analysis and considering calculation of a point of profitability. Here factors – receptor, administrative and effector take place. In experience information of the construction enterprises of Rostov-on-Don was used. The profit after introduction of innovations grows quicker, than before their introduction since the point of profitability decreases after calculation of the organization for invested in innovations. On examples the criterion of expediency of merge of the construction organizations – the carried-out amount of works is shown. On the basis of this criterion it is possible to solve a problem of streamlining of operations in construction systems by integration of information space of organizational and technological, economic and other applied systems.
