Digital Omnichannel marketing is viewed the answer to future marketing however, the concept is mired with problems related to the energy and carbon footprinting. Therefore, this study proposed energy efficient network of a complex topology of data access and marketting, where the nodes function as an objects with unique characteristics and create digital customer value network. It is believed that competition has transformed into a contest of online platforms in energy efficency as well in economic efficiency. It is emphasized that there is no alternative to multichannel interaction at the present stage of implementing digital business solutions. In this study, authors have developed omnichannel interaction algorithms based on mathematical models. The proposed approach supplements the digital twin model with economic indicators and methods. Results and analysis of multidimensional structures allows for omnichannel network digital interaction and improves the digital marketing approach. To consider the formation of a network configuration of customer service, developing the idea of digital interaction between participants in consumer value chains. The study conclude and recommend to expand the methodology of digital marketing involving alternative channels of interaction and energy efficency by including a mathematical apparatus for analyzing multidimensional structures (n-D structures).

The article considers the necessity of active implementation of monitoring, as a managerial instrument, into the process of urban development. It will provide the creation an effective informational support of sustainable development of the modern cities. Today the central part among them belongs to megacities. The presented research focuses on megacities from the positions of the most significant trends of globalization. On this basis the author makes a number of proposals in a framework of creation the monitoring system for effective informational support of sustainable urban development. The operation of this system corresponds to the basic foundations of the Information society and the modern conditions of postindustrial development.

The article examines the changes in the requirements for the development and implementation of innovations in the process of forming and improving supply chains in the face of increasing economic instability. Economic instability is presented as the most important trend in the modern economy and significant factor forming new requirements for supply chains. This, in turn, involves the improvement of applied technologies and development of new technologies, as well as the search for progressive technical and managerial solutions to meet the interests of a wide range of business entities and consumers of goods and services. A distinctive feature of this study is the fact that economic instability is viewed by the authors through the prism of both economic and non-economic processes having, inter alia, an impact on the economic system, including political, military, environmental, epidemiological and other processes. The article focuses on the COVID-19 coronavirus pandemic, as well as its impact on logistics solutions, and the specific demands on supply chains. It is substantiated that the introduction of technical and managerial innovations in this area will allow us to take into account the features and consequences of the impact of COVID-19 on the economy and to effectively influence the processes associated with improving supply chains. Thus, it will ensure compliance with the requirements and conditions determined by modern conditions associated with increased economic instability.

The article considers the need to provide personification of Internet interaction with consumers in the conditions of the digital economy. This involves the creating an effective system of communication between the company and its target audience, taking into account the individual characteristics of consumer behavior and customer activity in social media. On this basis, the authors make a number of proposals in the context of using the possibilities of the Internet technologies. There are specified sequence of actions for the organization of personalized interaction with consumers and developed algorithm of managerial impact in the process of implementation of instruments provided by the Concept "Internet of things".

Since there is a lack of a strong CSR platform in the Iranian corporate environment, especially in the food and pharmaceutical industries, the proposed and existing strategies can be utilized to empower employees and the general public, improve executive processes, improve quality and customer satisfaction, and finally, organize financial and accounting reports. Hence, this study seeks to determine and evaluate strategies to improve the concepts and domain of corporate social responsibility (CSR) of food and pharmaceutical industries in Iran based on the requirements of sustainable development theory. This study analyzes the data of 22 companies active in the food and pharmaceutical industries listed on the Tehran Stock Exchange (TSE) over a period of six years (2014–2019). Eighty-three indicators were used to evaluate the performance of social responsibility based on economic, social and environmental dimensions. The Pareto approach has been used to determine the most important unmet current requirements. Then, using the Delphi method and content validity, appropriate strategies were determined. Finally, a correlation matrix was used to determine the most important and comprehensive strategies. Findings showed that 14 requirements in the field of corporate social responsibility are of great importance and with six strategies, the necessary measures to meet those requirements can be covered.

The article analyzes the current state of the Russian heat power engineering and identifies the main problems in its economic development. From the position of an integrated approach, the problems of the Russian heat supply system are divided into three categories: technological, economic and social. The using electricity for the needs of heat supply is determined as an effective way of solution these problems. In this context the electric heat supply is offered as an alternative to the modern heat supply system. The article identifies the main factors of electric heating, showing its economic advantages over other types of heat supply systems. On this basis the authors justify the prospects of electric heating system from the point of view of economic development of the Fuel Energy Complex and the national economy as a whole.
