The functioning and proliferation of global value chains are becoming increasingly important in supply chain management operations. The study aims to identify the drivers of value-added growth as a key indicator of effective global supply chain management. This study provides an opportunity to compare the most influential factors of successful supply chain management through the prism of value added in Russia, China, Japan, Saudi Arabia, Switzerland, and the USA. A comparative economic-mathematical analysis of the influence of variables determining the degree of a country’s inclusion in global value chains was conducted. On this basis, it was proved that the IT sphere can become a competitive advantage for Russia and a prerequisite for inclusion in global value chains. Based on the assessment of supply chain management effectiveness in the context of inclusion in global value chains, it is found that the effectiveness of countries’ participation in them is determined by several drivers. Within the framework of global value chains, there is a change in the mechanism of international competition, in which each of the participants of global chains is interested in the efficiency and success of partners.

The purpose of this article is to propose a new design for a sustainable built environment using a specific business system as an example that transforms and implements modular systems and UV lighting to prevent the spread of infectious agents after COVID-19, which directly affects the ability of some types of businesses to function. The paper explores the possibility of purchasing, introducing and using UV radiation for disinfection of premises and the destruction of potentially dangerous viruses and bacteria. The proposed model allows self-isolating persons to adapt to the changing reality and remain productive consumers of goods and services within the business system under study. The modular system, combined with germicidal UV lamps, due to their ability to inactivate viruses, effectively creates a safe hygienic environment, which affects the attractiveness of the territory for visitors and increases the number of ‘contacts’ of the consumer with the company and brand.

The study aimed to develop recommendations for the optimization of settings in which the crowdsourcing project takes place. Findings show that crowdfunding projects are hybrid and include the elements of crowdsourcing, crowdsensing, crowdfunding, crowdworking, and crowdsourced recruitment. The predominant role of security guarantees was identified. It turned out that relations irreducible to a simple hierarchy pose many challenges. The results indicate that leading issues include the lack of financial guarantees and the likelihood of information leakage to competitors. Hence, the priority is to manage the exchange of money and information. An interesting finding demonstrates a positive correlation between project success, ethical conduct, and fair distribution of gains. The protection of intellectual property rights was no less important. As it was concluded in the course of analysis, the more successful the project, the more thoroughly it addresses the protection of someone else's intellectual property.

The above article, published online on 17 August 2021 in Wiley Online Library ( wileyonlinelibrary.com ) has been retracted by agreement between the journal's Editor‐in‐Chief, Laura Corazza and Shaista Wasiuzzaman and John Wiley & Sons Ltd. The retraction has been agreed following concerns regarding manipulation of the peer review and publishing process. Concerns were originally raised by a third party (1). Further investigation by the publisher has found manipulation of the peer review process, and overlapping text with other publications. The retraction has been agreed because the peer review of the article was compromised and there is unattributed overlap between this article and several other articles (2)(3). Abalkina, A. (2022).

The article presents a mathematical model for distributed taxi fleet operations. A technological approach based on mathematical models of transport systems using the Hungarian algorithm was used to model the arrangement of repair and maintenance in the absence of centralized management. The literature review on taxi fleet robotics has shown that central management is the cause of increasing transport service costs up to 30%. The results of approximating the cases of repairing and maintaining the taxi fleet in the absence of centralization to the lognormal and Gaussian distributions are provided based on 2019-2020 data. A blockchain scheme for work organization and maintenance of the taxi fleet within the decentralization framework is developed. The statistical analysis of repair and emergency maintenance cases in the distributed taxi fleets calculated per 1000 cars was 3.6 to 15%. Pearson's criterion χ2 was from 0.001 to 0.17. Statistical significance values of the results were p≤0.005. A multivariate cluster analysis of the accident or technical failure occurrence among the distributed taxi fleet vehicles was conducted in months, taking statistical data for the last two years. An algorithm that allows performing optimal assignments for a distributed taxi fleet is developed in this work. A sample calculation of the optimal allocation for taxi fleet vehicles distributed in the state of minimum vehicle repair cost based on the Hungarian algorithm was provided. The application of this algorithm also makes it possible to determine the optimal destinations for vehicles in the taxi fleet. © 2021, Universitas Muhammadiyah Magelang. All rights reserved.
