- ПубликацияТолько метаданныеAnalysis of the Stability of Choosing the Decommissioning Option for Objects of Atomic Energy Use(2019) Abakumova, A. S.; Bochkarev, V. V.; Ivanov, V. V.; Kryanev, A. V.; Иванов, Виктор Владимирович; Крянев, Александр Витальевич© 2019, Pleiades Publishing, Ltd. Abstract: The stability of choosing the decommissioning option for objects of atomic energy use (OAEU) is analyzed. An algorithm for studying changes in the factor values due to variations in the OAEU characterization parameters is described. Numerical examples are presented which implement the proposed schemes for calculating indicators, determining the most preferable options of OAEU decommissioning, and analyzing the stability of the decision of choosing the OAEU decommissioning option with possible factor values.
- ПубликацияТолько метаданныеAnalysis of the Features of the Network Traffic in the Trunk Channel: Zero Channel(2021) Ivanov, V. V.; Tatarinov, I. I.; Ivanov, V. V.; Kryanev, A. V.; Prikazchikova, A. S.; Иванов, Виктор Владимирович; Крянев, Александр Витальевич© 2021, Pleiades Publishing, Ltd.Abstract: We showed earlier that, when aggregating network traffic measurements, starting from a certain aggregation window, a stable distribution is formed, which is approximated with a high accuracy by a lognormal law. Despite the fact that, in general, the results of network traffic measurements agree with this law, in the region of the small values of traffic intensity and transmission rate of network packets, there is a noticeable discrepancy between this law and the measurements. In this study, we discuss the problem of a peak arising in the low-intensity region during the aggregation of network traffic measurements. Taking into account the location of the peak in question, we called it the “zero channel” (ZC)
- ПубликацияТолько метаданныеReconstruction of Multivariable Functions Under Uncertainty by Means of the Scheme of Metric Analysis(2021) Sevastyanov, L. A.; Udumyan, D. K.; Kryanev, A. V.; Ivanov, V. V.; Крянев, Александр Витальевич; Иванов, Виктор Владимирович© 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.The problem of the reconstruction of a multivariable function whose values with chaotic errors are given at a finite number of points is considered in the paper. The problems of this kind arise when solving applied problems in various fields of research, including physics, engineering, economics, etc. We propose a new approach for solving this problem with the help of a metric analysis. The paper gives numerical two examples of the solution of the problem of the reconstruction of multivariable function, demonstrating the effectiveness of the proposed scheme. In the first example, the results of estimating the exact value of the function at the points where the values of the function with errors are known, in the second example, the results of reconstructing the physical characteristics of the core of a nuclear reactor are presented.

- ПубликацияТолько метаданныеMathematical Modeling of Exhaustion Process of Extracted Mineral Resources Using the Example of Natural Uranium(2020) Ul'yanin, Y. A.; Ivanov, V. V.; Kryanev, A. V.; Sliva, D. E.; Kharitonov, V. V.; Иванов, Виктор Владимирович; Крянев, Александр Витальевич; Харитонов, Владимир Витальевич; Факультет бизнес-информатики и управления комплексными системами© 2020, Pleiades Publishing, Ltd.Abstract: This paper is devoted to the development of mathematical models of exhaustion process of extracted mineral resources. Our new model combines the advantages of previous models and is devoid of their disadvantages. The model uses the transition of the growth rate of extraction of mineral resource to stationary value. The initial known parameters of the model include the explored residual volume of the mineral resource, the initial volume of its extraction, the initial growth rate of its extraction, and the indicator of decreasing rate of extraction growth. The model is applied using the example of predicted extraction and exhaustion of natural uranium.
