“…Long-term transformations in the socio-economic sphere aim to solve fundamental issues of stimulating reliable and innovative alternatives to post-pandemic economic recovery. Vo (2020) views the COVID-19 pandemic from two perspectives -as an economic crisis and a crisis in the public health system. The author argues that it is essential to study changes in the agricultural market and the energy market during the crisis.…”

The article uses neural networks to model the effects of quarantine restrictions on the most important indicators of the country's socio-economic development. The authors selected the most relevant indicators and formed a specific sequence of its calculation to study the direction of transforming the trajectory of socio-economic development of a particular country due to quarantine restrictions. They used a multilayer MLP perceptron and networks based on radial basis functions. They chose BFGS and RBFT algorithms in neural network modeling. Collinearity study was the basis for data mining in terms of key factors of change. The author's approach is unique due to an iterative procedure of numerical optimization and quasi-Newton methods ("self-learning" and step-by-step "improvement" of neural networks). The model projected gross domestic product and the number of unemployed in the country affected by the COVID-19 pandemic over the three years.

“…In immature markets with high share of mutual funds, financial risks,however, grew unexpectedly, causing essential shifts in activity (Nicolescu et al, 2020). Regional differences in the pandemic consequences reflect the distribution of enterprises and labour force involved in the specific activity (Kuzmenko et al, 2020), including the fields strongly influenced by the pandemic crisis (Cepel et al, 2020;Vo, 2020). This list is by no means complete.…”

Covid-19 brought the new reality into every-day life, global economy, and various sectors, including independent convenience stores. After the first and during the second wave of Coronavirus in the United Kingdom (mid-November 2020), the overall situation was very dynamic and turbulent. This paper is thus aimed at answering the question how the independent convenience stores sector in the United Kingdom functions in the Covid-19 reality. We analyse such issues as the recession phase in the global economy, and challenges the independent convenience stores sector in the UK faces, including the changing aspects of the consumer shopping behaviour. We identify the changes in the footfall, basket spend, sale, product categories, etc. Finally, we conclude that the convenience store sector in the UK is relatively resistant to Covid-19 pandemic and emphasise the most challenging consumer behaviour aspects in the middle of the Covid-19 pandemic.

Improving the Development Technology of an Oil and Gas Company Using the Minimax Optimality Criterion

et al. 2021

The article deals with the problem of adaptation of the Russian oil and gas company (Novatek, Russia) to the rapidly changing external environment, the avalanche of data from competitors, and the need to filter important information for business development and the prosperity of the industry as a whole. The approach is based on the system of integrated software monitoring of key business processes at the enterprise developed by the authors—from the formation of the idea of a new product to its implementation to paying customers. The scientific novelty lies in the use of an optimization model that allows for minimizing the maximum losses of the investor at all levels of decision-making, from the distribution of capital between companies, to the optimization of internal reserves to increase the competitiveness of the company. The toolkit is a minimax model that allows you to redistribute the shares of investor influence at the portfolio level, and then within the business processes of each company selected by investors, in order to achieve the optimal solution in accordance with the selected estimated indicators. Application of the well-known portfolio investment models of Markowitz, Tobin, Sharp, etc. is not possible due to the lack of necessary data on the basis of which the probabilistic parameters involved in the model are estimated. Even if we get them, it is necessary to take into account the level of correlation influence of the technological process in the composition of each subsystem, which is unacceptable for the data used, as it leads to a strong increase in errors. Using minimax and a systematic approach allows you to minimize such errors by choosing a balanced concentration of distributed assets for both the investor and the buyer. To this end, a three-way analysis of the company’s development was carried out and a technology for comprehensive improvement of the company’s activities was developed in the following areas: the company’s rating in the industry, financial condition, and interaction with counterparties using merchandising technologies. Tools for optimal image zoning at the Novatek site using the minimax approximation criterion have been developed. The technology provides a procedure for creating a comfortable mode of image perception based on high-tech visualization of merchandising, zoning of the screen area, and a mathematical approach that allows you to develop a calculation algorithm.
