The article proposes a computational model with eight-step algorithm for usage bond issuance as a systematic instrument to finance corporate assets by optimal capital structure. The crucial model points are methodologically accurate calculation of the average credit spread accounting the difference in...

In this article, we have developed a formal decision-making model for an enterprise to market a single product in the future. The model is built in the form of an antagonistic two-person game. The payoff function is the profit of the enterprise. We took into account the limitedness of the target segment...

Depreciable bonds issues can significantly expand the issuers’ abilities to manage public debt. The purpose of the study is to suggest possible options for a model for fulfilling obligations by issuers of depreciable sub-federal bonds. The study was conducted using a discrete grouping constructed according...

The article is devoted to the problem of forecasting indicators of living standards using neuroevolutionary approach. The NEAT method is considered that allows generating the neural network topology automatically. The paper proposes modification of this method and its implementation based on the activation...

The problem of a comprehensive assessment of the effectiveness of enterprises’ innovative activities is considered. The multidimensional criterion has been developed for a comprehensive assessment of innovative projects efficiency, providing a justification for the project quality and its quantitative...

The article discusses the specifics of building mathematical and analytical insurance company risk models when changing consumer behavior. The concept of a model is given. Various types of models for consumer market analysis developed abroad and in Russia are described in order to conduct marketing activities...

The article deals with the problem of risk reduction of the banks’ credit portfolio. The new mechanism for credit portfolio quality management is proposed, featuring a combination of quantitative and qualitative criteria for assessing the credit portfolio quality and its monitoring. This mechanism supports...

Factor structure of expected graduate’s wage is considered in the paper. The analysis of eight regression estimates for 2007–2009 and 2012–2016 of Russian University students’ wage expectations demonstrates consistency of estimates of all coefficients but regional dummy and wage of working students....

The concept of random variables network used to model the complex system of random nature is discussed. The problem of threshold graph identification to network analysis of the complex system is considered as multiple decision statistical procedure. The properties of robustness of different tests for...

The main purpose of this research is to develop methodological support and economic and mathematical tools for managing and evaluating the effectiveness of innovative projects based on binomial models of real options. The subject of the study is a computer program algorithm for using the binomial model...

The authors build a simulation model focused on the risk management of a commercial bank’s project portfolio with a detailed description of the relevant methodology. The paper explores the logic of the simulation algorithm, which is the logical structure of the system functioning model. It obtains insights...

The instability of the stock market spurs investors to seek alternative ways of allocating financial resources. In this case, art assets could be considered as an attractive investment. Due to the uniqueness, specific costs, and risks inherent to the artworks, the fine art market is very heterogeneous...

The work discusses the method of recognizing the state of a learner using artificial neural networks based on the analysis of electroencephalogram signals during the assimilation of educational material using a hardware–software complex of a robot – an assistant teacher of anthropomorphic type.

The paper presents research on the use of the results of the analysis of signals of brain activity of students for decision-making in educational robotics. Signals of brain activity were obtained using electroencephalograms (EEG). Assessment of the state of the student was carried out on the basis of...

The paper presents studies of electroencephalogram (EEG) signals of epilepsy patients based on wavelet transform and calculation of the total signal energy. The object of the study was a patient aged 17–22 years diagnosed with focal (structural) epilepsy, mesial sclerosis on the left and focal cortical...

In this paper, we conducted an experiment for comparison of the graphs generated by Erdős-Rényi, Barabási-Albert, Bollobás-Riordan, Buckley–Osthus, Chung-Lu models and a web graph constructed using real data. Twitter data have been employed to construct social network, and C++ has been used for network...

The paper proposes a genetic algorithm (GA) for finding central vertices in a graph. The algorithm uses a different approach to the method presentation of the solution and describes a new look at the crossover process of GA. The algorithm was compared with existing exact and other genetic algorithms...

The paper presents an algorithm for smoothing time series with seasonality. The proposed method is based on median smoothing and the Hodrick–Prescott decomposition. Using a software implementation in the R language, the correctness of the developed algorithm is checked; it is also compared with other...

The article presents the results of a study of innovative spillover effects using Data Envelopment Analysis (DEA) tools. The study is novel, in that an assessment methodology has been developed based on the Malmquist index and an output-oriented DEA model has been built to analyze the dynamics of the...

In this paper, we analyze σ- and β-convergence using data from the socioeconomic development of the Russian regions and reveal the role of spatial autocorrelation in regional economic development. We consider 80 regions of Russia for the period 2010–2017. We estimate spatial autocorrelation based on...
