    Methods virtualization in chemmotology researches
    (National Aviation University, 2019) Moiseev, Alexandr; Oreshencov, Alexandr; Grishin, Nikolay
    Virtualization in chemmotology allows to carry out extrapolation of laboratory results on regular conditions of operation, and also return recalculation of these conditions in adequate parameters of qualifying experiment. Efficiency virtualization is shown on examples of optimization of mathematical models, perfection of qualifying experiments and forecasting of their results.

    Statistical methods in virtualization
    (National Aviation University, 2019) Moiseev, Alexandr; Grishin, Nikolay; Oreshencov, Alexandr
    The importance of virtualization tools for solving the problems of identification of statistical models based by the results of qualification tests is shown. During identification abnormality of distributions of measurements error of mineral oil characteristics was established. For construction of algorithms of processing of measurements a number of alternative approximations is synthesized. To assess the reproducibility of the virtual qualification results, the distribution of Cochrane statistics and Grubbs statistics is constructed. Parameterization of the criterion model is proposed based on the results of predicting the effect in extreme conditions. The choice of conditions is proposed to be carried out by the method of successive approximations in the framework of factor analysis. The importance of virtualization tools for solving the problems of identification of statistical models based by the results of qualification tests is shown.
