A model has been developed for the optimization of the share structure of an investment portfolio in high-tech projects supported by the leaders of the leading industry companies in Russia. Several indicators (financial leverage, integrated rating of companies, industry rating) were applied in the decision support system for the shared distribution of investments. High-tech production is based on innovative technologies for saving resources, the resiliency of systems for transporting and transferring raw materials and finished products within Russia, so the main income will remain within the country. It is possible to export high-tech products, rather than raw materials, which will increase export revenues. Investors will invest in high-tech projects of Russian companies, taking into account the targeting of investment development. The guarantee is the stable financial position of the companies and the competitiveness rating. Methods: The authors propose a new approach that does not contradict modern rating scales, based on a hierarchical rating procedure and fuzzy logical rules that allow you to build an integral rating in the form of portfolio shares from the whole. A higher share shows an indicator of the higher investment attractiveness of companies. The industry rating is obtained based on the principle of the company’s first affiliation to the highest rating indicator. The final minimax portfolio is based on the initial ratings in a circular convolution and is then adjusted by industry. A software package has been compiled that allows the testing of the method of capital allocation between investment projects for the largest companies’ leaders of high-tech industries in Russia. This software uses the author’s method of multi-stage analysis, the evaluation of financial coefficients, the integral ranking and the correction of the solution taking into account the industry attributes. Results: The results are presented with computer-aided design (CAD) in the form of an algorithmized decision support system (DSS). The CAD system is based on a hierarchical algorithm, based on the use of a multi-level redistribution of investment shares of high-tech companies, taking into account the adaptation to the requirements of the return on investment portfolio. When compiling the portfolio, the minimax optimality criterion is applied, which allows the stabilization of the risk by purposefully redistributing funds between the companies involved in the analysis. The authors of the article have compiled an algorithm for the software implementation of the model. Features of the rating approach: the use of the author’s mathematical apparatus, which includes a hierarchical analysis of the ranked indicators of the financial and economic activity of companies, taking into account their priority, and the use of a minimax approach to obtain a rating assessment of companies, taking into account the industry attributes. Development: The proposed approach should be used for targeted financing of large industry companies engaged in the implementation of high-tech projects.

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.

Purpose – to review literature about circular supply chain (CSC) theories, methods, frameworks, and appli-cations in industries. For organizations to incorporate circular economy (CE) principles in their supply chain frame-work are required to address the main circular processes. Previous attempts of frameworks aim at the comprehensive approaches or too theoretical for organizations to use them. The objective is to propose a theoretical framework that allows organizations to prioritize main circular processes in order to start improving or introducing new circular pro-cesses in the supply chain. Research methodology – the methodology of the article consists of a literature review and information synthesis for the formulation of the theoretical framework. Web of Science database was used for literature review with the key words of “circular economy supply chain”. Findings – formulated theoretical CSC framework contributes to the CSC research field with a more organization-ori-entated approach. Research limitations – the proposed framework is limited through only theoretical propositions and is more limited in its scope compared to other researchers. Practical implications – organizations in the supply chain such as manufacturers can understand through a framework main processes required for CSC. Originality/Value – compared to other researchers this work emphasizes and proposes CSC development from an organizational perspective rather than from a holistic approach.

Purpose – this paper aims to ground an extended model of sustainable regional development, which would serve as an instrument to estimate and, ultimately, minimize the harmful impact of ecological threats on sustainable economic development. Research methodology – Ecological Carrying Capacity (ECC) concept needs to be applied; chosen “COVID19” is as a valid sample of ecological pressure on regions to study its harmful impact on one of the ecological resource “GDP” for the vital group G20 countries that control 75% of the world’s GDP. Secondary data were collected from the Passport database’s Macro model for evaluations and predictions. Findings – GDP drop due to COVID19 in developed countries is higher than the developing countries of the G20 group, indicating the need to utilize the global sustainability EGB model instead of the SLB model. Research limitations – considering one macro model indicator (GDP), which could be enhanced by including other indicators. Practical implications – the obtained results promote a consistent reaction pattern of GDP growth with ecological threats in differently developed countries to devise economic policies on how to mitigate these threats’ globally. Originality/Value – previous studies mainly focused on identifying ecological threats, whereas our study studied how to measure these threats’ harmful impact on countries’ economies.

Purpose – in this article, the authors propose a management model for Critical Infrastructure cybersecurity, further development of a model developed by Limba, Plėta, Agafonov, and Damkus (2017). Research methodology – methodology consists of researching the best practices in cybersecurity management for Critical Infrastructures and evaluating the best element to be included. The article offers an overview of the model, including structure and objectives, and further analysis that focuses on pre-existing CI management frameworks. Findings – main results show that, although previously published protocols and models contain valuable elements, there is still the need to implement a comprehensive model which can be applied to every type of CI. Research limitations – research might have been limited due to the lack of a unitary approach to cybersecurity management for CI, meaning the lack of possibility of reference to a similar model and approach. Practical implications – model which is presented in the article could offer a new approach to CI protection strategies and could be the beginning of a more structured approach towards their protection. Originality/Value – model was created by the authors with references to past published protocols and models, which are present in the quotation in the text as well as the bibliography.

The strong interdependency between economic growth and conventional energy consumption have led to significant environmental impact, especially with respect to greenhouse gas emissions. Conventional energy-intensive industries release increasing quantities every year, which has prompted global leaders to consider new approaches based on sustainable consumption. The main purpose of this research is to propose a new energy index that accounts for the complexity and interdependences between the research variables. The methodology is based on Principal Component Analysis (PCA) and combines the key components determined into a score that allows for both temporal and cross-country comparisons. All data analyses were performed using IBM SPSS Statistics 25™. The main findings show that most countries improved their economic performance since 2014, but the speed of the improvement varies a lot from one country to another. The final score determined reflects the complex changes taking place in each country and the efficiency of the governmental measures for sustainable economic growth based on low energy consumption and low environmental pollution.

Today, sustainability, sustainable development and clean environment come to the fore worldwide. Consequently, the concept of sustainability has been introduced in project management. Sustainability issues have gained particular attention in the real estate sector. However, despite the fact that this sector has a huge impact on the environment and society, real estate projects are most commonly chosen taking into account only their risk and return, and a very limited number of indices and methods are available to assess their sustainability. Moreover, all of the existing indices and models for assessing the sustainability of an investment project take into account only three dimensions of sustainability—environmental, social and economic. Therefore, the novelty of this work lies in constructing a real estate sustainability index (RESI) relying on an additional sustainability aspect—i.e., a technological dimension. The developed sustainability index could be useful in evaluating and comparing real estate projects. It would also promote technological progress and investments in new technologies within projects as sustainability is also considered in a new, technological dimension. A research study was carried out between September 2020 and December 2020. Following an analysis of the literature and different sustainability-related standards relevant for the real estate industry, sustainability criteria were chosen and then grouped into four (environmental, social, economic and technological) categories. The selection and ranking of the most relevant sustainability criteria were performed through a survey. The index was compiled by applying multi-criteria decision making methods.

Adaptation strategies to the climate change include measures that can be taken to take account of the new climatic conditions. This paper aims at assessing the effects of climate change on environmental sustainability. This sustainability constitutes a major problem in many countries and regions around the world that experience industrial pollution, degradation of land as well as natural disasters caused by the global warming. The paper shows that adaptation strategies are often parallel strategies that can be integrated simultaneously with the management of natural resources. They can make resources more efficient and resilient to climate change. The paper shows that reducing the carbon footprint by more than 50 percent by 2030 and eliminating it by 2050 might be a viable solution how to tackle the climate change and support the environmental sustainability.

This paper analyses innovative activities, including renewable energy sources (RES) in the housing market, the motivations for their introduction, effectiveness, benefits, limitations and management—which are open and current problems of Polish and international sustainable construction. This problem is part of a research gap concerning, among others, the role of developers and entities responsible for introducing energy innovations into housing construction. The aim of the paper is to analyse innovations, with particular emphasis on RES, introduced by residential developers in Poland in the context of global trends. The work is based on the results of surveys conducted among developers of the primary housing market. The research of 130 questionnaires received from entities such as multi-storey buildings and multi-family houses in Poland, was carried out on a nationwide sample using the CATI Computer Assisted Telephone Interview method. The results of the survey research were summarized by setting research hypotheses, which were verified using the significance test based on the Laplace normal distribution. The research conducted has shown that residential developers in Poland point at, among others, competitive pressures, concern about the quality of products and services offered, increasing market share or satisfaction and increasing customer requirements. This clearly shows that the implementation of innovation is perceived through the prism of increasing competitiveness. Furthermore, developers operating in the more competitive markets—nationwide and on the market of the five largest Polish cities, usually larger companies, showed a greater willingness and even the need to introduce innovation in their activities. In the study, developers as one of the barriers of introducing innovations, apart from the lack of adequate support, mainly from public entities in the field of, inter alia, appropriate law favouring the implementation of innovations and financial support, indicate difficulties of the client’s market manifested by the lack of knowledge and identification of needs in the field of innovation, and the lack of willingness to pay a higher price in regard to the product with higher innovation level. In the paper, the authors recommend developers, among others, to implement in the management process the identification of possible to implement innovations and the customers’ needs in innovations with education in the field of possible innovations and its benefits. The article indicates the need to intensify the implementation of innovations in housing projects in order to increase competitiveness and to meet the European Union’s requirement regarding the use of renewable energy sources.

This research tackles effective and functional management practices in energy consumption using advanced technological solutions to mitigate unexpected events. This study specifically focuses on the recent COVID-19 pandemic that led to a reduction in energy consumption and therefore meddled with the project management’s status quo for the energy sources. Moreover, this research analyzes the role of information and communication technology (ICT) solutions in energy management before and after the recent coronavirus pandemic turmoil. This study also examined the role and place of sustainable energy resources in the effective management of energy consumption during the COVID-19 pandemic. The main purpose of this research is to demonstrate how the recent coronavirus pandemic affected energy consumption and energy prices in many countries and how it paved the way for the new ICT in managing energy consumption. This study elaborated a model to show how these changes evolved in selected European Union (EU) Member States. It turns out that adjusted electricity consumption, as well as the average daily spot electricity prices for the baseload power in the EU countries, declined, and this trend is likely to continue in the next years to come. Due to the COVID-19 pandemic, substantial changes in the economy led to reduced office space usage, cutting commuting and business trips, and bringing commercial travel almost to a halt, further shifting the energy balance towards renewable energy sources (RES). Besides, it becomes apparent that ICT solutions used in maintaining and superintending the energy balance are gaining popularity and wide recognition worldwide and will help pave the way towards modern and smart high-renewables grids.

Sustainable consumption, provision of a clean and healthy environment, as well as improvements to the quality of life of current and future generations, are all integral parts of the sustainable development strategy, which is understood as a compromise between the environmental, economic and social objectives of society. The pro-environmental and pro-social consumer engagement in sustainable consumption may lead to behavioral change, thus contributing to the resolution of current global challenges. Although recently the pro-environmental and pro-social engagement concept has received considerable attention, there is still no consensus on what determines it. Moreover, the recent research is limited to identifying individual factors of this phenomenon. Therefore, the purpose of this study is to explore the factors that determine pro-environmental and pro-social consumer engagement in sustainable consumption. The authors employed a qualitative method approach, conducting semi-structured interviews with consumers engaged in sustainable consumption in Lithuania. The research results reveal that these consumers were affected by cognitive, attitudinal and psychosocial factors. In terms of external factors, consumers named contextual factors for sustainable consumption, social norms and the promotion of sustainable consumption. Research results also show an additional internal factor of perceived responsibility, which means perceived duty as an individual to do good for society and the environment.
