Literature review related to the data exploration methods in marketing showed that the number of publications and software tools in the field of exploration data analysis of business processes has been increasing since 2015. The contribution of the given research lies in the hypothesis of the possibility to construct a quantitative model of a business process for big data containing fraud. At the first stage, we performed data cleaning and reduction, examined data distributions, and identified issues such as extreme values that supplement the previously developed visualization approach. The descriptive analysis helped us to describe the significant number of categorical features. We emphasized the data outliers that should be marked for further research.

The technique of combining BIM and simulation modeling is considered. The increasing role of BIM in building projects, along with the poor quality of the control aspect in BIM, is noticed. The enhancement of the BIM in the field of control modeling using different simulation models of logistics and evacuation is proposed.

We consider the problem of choosing the degree of localization of production in Russia when implementing investment projects for the transfer of Western technologies. The problem is considered on the example of launching the production of innovative locomotives at Russian Railways. This type of investment projects refers to multipurpose projects. Each project participant has his own goal, the effectiveness of which should be assessed. A method is proposed for solving the problem according to the criterion of minimizing the "life cycle cost", taking into account the coordination of the interests of the project participants.

In the context of the Coronavirus pandemic, it is crucial to analyze society's reaction to the information agenda related to the pandemic. This study examines news produced and broadcast by socially significant sources of information (in particular, accounts of news agencies, magazines, and newspapers) on the online social network VKontakte and Vkontakte users’ consumption of these sources’ news.

Authors of this article review and analyze the main trends in the modern distribution networks development for electricity supply. These distribution networks can function effectively only with extensive and adequate use of parametric and non-parametric identification. We propose the general approach to parametric identification in power distribution networks. The authors of this article developed the applied method for the parametric identification of voltage converters in digital substations based on this approach. We select an adequate model structure of simulated electrotechnical objects. Parametric identification results are input data that organize the diagnostic process of digital signal converters.
