Prompt development of information technology has made an essential impact on many industries. There appeared a concept "Industry 4.0" symbolizing the fourth industrial revolution. The given concept is closely connected with such promising technologies as the Internet of Things, blockchain, fog computing, Big Data. In the present research, the sphere of the mining industry is examined. We discuss the possibility to increase the efficiency of mining enterprises at the expense of the development of common information space based on modern digital technologies. We analyze security problems at the level of data flow between the participants of the production process on a mining enterprise. We define the problem of providing the reliability of data on the production course on mining enterprise in the conditions of the possible connection loss between the control center and separate technological units. We offer a new approach to the solution of the given problems, based on the technology of blockchain and digital watermarking. The computing experiment is conducted presenting a possibility to implement the offered approaches on common models of microcontrollers.
Modern shipbuilding is guided by the theory of overall planning and optimization, using the principle of group technology and intermediate products. According to regional division, the production consists of Shell (hull), outfitting (outfitting) and coating (coating), so as to realize the integration of design, production and management and continuous general assembly shipbuilding. However, the data security and the data synchronization of various manufacturers need to be solved, in order to solve the needs of collaborative development, rapid response and safe operation in the open network environment of flexible collaborative manufacturing of ships. Based on the scene of shipbuilding supply chain, this paper explores the application of blockchain in the shipbuilding process, and proposes a cloud chain hybrid distributed production based on the value transmission production mode brought by blockchain technology. The distributed intelligent production mode can strengthen the enterprise safety production in the process of collaborative development of ships, improve the integrity, anti tampering and traceability of supply chain data, improve the status quo of equipment access confusion, realize the long-term and continuous supervision of all aspects of the supply chain process, and improve the safety and reliability of the process.
Blockchain technology has garnered much hype since the introduction of Bitcoin, but over a decade later, the technology is still lacking mature use cases outside that of cryptocurrencies. This paper makes use of a systematic literature review to identify non-cryptocurrency use cases of blockchain to establish an overview of existing or hypothesized solutions using the technology. The identified use cases are subsequently assessed on their technology readiness level (TRL) using the guidance of established research [1] to determine the maturity of individual blockchain solutions described in peer-reviewed literature. By categorizing the individual use cases into groups, a generalized assessment of maturity for different application areas is assessed for blockchain technology. The literature review and subsequent estimation of TRL revealed that there are highly mature blockchain use cases, although they are quite limited in terms of industry-wide utility. As an example, the Everledger use case has tracked over two million diamonds and is estimated to be TRL 9 (the highest level) in the specific scope of diamond provenance tracking, but other luxury-tracking blockchain initiatives are years behind this [2].

Emerging technologies are always treated with caution, and Blockchain is no exception to this rule. The AECO (Architecture, Engineering, Construction, and Operations) sector is considered conservative when it comes to technology adoption, which is often positive in an industry that deals with a vital commodity that could harm humans or result in catastrophe. However, excessive caution also stifles innovation, as shown in the industry's low R&D expenditure when compared to other industrial activities. In recent years, the AECO sector has benefited from the adoption of new information management tools and systems that allow professionals to develop, share and store construction data more effectively. These tools have successfully tackled many of the traditional interoperability issues that have affected the industry, but several challenges remain unsolved. Indeed, effective real-world communication depends, not only on the compatibility between data formats and systems, but also on issues such as privacy, transparency, and trust. Blockchain has been adopted in different activities as a tool to address these issues, but its impact in the construction industry remains scarce. This paper presents a bibliometric study for the available literature on Blockchain implementation in the AECO sector. In addition to the bibliometric review, content analysis for the literature retrieved is presented to provide a clear vision of the current directions regarding Blockchain technology adoption. The purpose of this article is to evaluate the maturity of Blockchain in Construction literature using statistics based on the available bibliometrics in addition to content analysis. The main results show that although the number of articles about the use of Blockchain in Construction has increased, no studies that present ready to use solutions were found. Instead, the covered studies discuss the technical capabilities of the technology and suggest possible fields of implementation, such as smart contracts and automated payments. Study limitations include the limited amount of literature that can be found on major indexing services, which cover a relatively short reference period.
Nowadays Smart Factory concept becomes a reality. We meet the greatest challenge of implementing autonomous manufacturing processes such as an organization of robots interaction in the framework of cyber-physical systems. This issue seems to be one of the most important, as it is considered as the basis of fully automated systems and provides mechanisms for self-organization and decentralized control. In this paper, we describe Informational Space and messages interaction models as the way for robots communication, considered under the Smart Factory environment. The main contributions of the work are the developed models and a software simulator of an adaptive production model, that responds to changing customer personalized needs. The performed case study showed that the developed software simulator, based on the presented theoretical models, can successfully imitate the autonomous production process.

This article explores Blockchain Technology, and how it can be used in the context of information exchange between stakeholders in international supply chains and networks involving air transport. The article reviews the global experience with this technology of iconic companies (Maersk, Lufthansa, Walmart, Unilever, Nestle, Samsung, British Airways) in logistics and supply chain management. It highlights the features of international chains using air transport, which predominantly consist of two categories of goods: goods with high added value (electronic devices and their components, fashion industry products, jewelry) and goods with strict delivery time requirements (pharmaceuticals, live animals, perishable products, e-commerce products and mail). The study shows that perishable goods have great potential for increasing airline cargo turnover. However, at present, there is no single universal tool for managing their supply chains since the tools used (ERP, SRM, TMS, WMS) do not provide complete transparency of information exchange between all stakeholders. The most problematic stage in the delivery to control steps in the delivery of perishable goods by air occur on the ground, while goods are being handled at the airport of departure and the airport of destination. Difficulties arise while checking the correctness of paperwork, labeling and information authenticity about the product origin. The article suggests using block chain blockchain technology in combination with IoT and smart-contract technologies for SCM of perishable products using air transport. The use of this technology allows to reduce the time of document verification procedures. Customs clearance and phytosanitary control could be vastly improved. Overall tracking and monitoring of a product from the moment of its production to the destination simplifies the identification of any counterfeits, improves the quality of food safety control. A greater level of control becomes possible in logistics operations, to determine liability in possible delivery conditions’ violations cases. Overall optimization of the logistic processes, automatization of the execution of verified financial transactions can be achieved. The use of these technologies in combination with innovative technologies for food quality control will significantly reduce logistics costs in the supply chains of perishable products.

The article covers the possibilities of comprehensive use of identification technologies and Distributed Ledger Technology (DLT) for increasing the efficiency of electronic services provided through multi-purpose student cards. The main advantages and disadvantages of the existing intellectual document emission systems in the Belarusian education system are assessed, including: centralized (the “Student Card” project) and decentralized (the electronic student card) ones. The proposal to use the DLT-model for issuing multi-purpose electronic student cards combined with bank payment cards has been grounded. Such model makes it possible to implement new functional capabilities when providing electronic services and has a number of advantages over the existing systems of electronic student documents issuance. The article describes how Public Blockchain and Private Blockchain can be used to issue and control intellectual documents, to accelerate the development of the electronic services provided through Smart Contract, and how the Smart Contract technology can be used to promote fair competition among electronic services providers. The methodology of evaluating the electronic services provider rating basing on the weighting factor of “usefulness” or “being in demand” is proposed. The article provides information on the expected effects of the proposed DLT-model implementation, obtained through the comprehensive use of identification technologies and distributed ledger technology.

In the article the components of technological basis of information and communication systems and the basic processes of its improvement are proposed and researched in general terms. The interaction between the user and Web service is monitored (information services, which are provided to users through Web technologies). Today, the evolution of the creation and formation of a multidimensional information communication environment is a determining factor for the innovative development and efficient functioning of all structures and social systems of the information society. Precisely by the communication sphere, that is transformed in the context of global information opportunities, the free access to knowledge, connections between people and communities, the accumulation, dissemination and enrichment of social experience are ensured. Today there is an active formation of a single global world economic, legal, information space to ensure the free and efficient business activity of all entities in the Internet. The world information space includes a system of services (services), the most important of which are: 1) Computing Services (Data / Computation Services) – means of placing data and their transportation between applications, access to computing and network resources; 2) Information Services – means of submission, processing, storage and access to information; 3) Knowledge Services – means of accumulation, submission, restoration, publication, search and processing of knowledge. Various institutional structures on the Internet create their own information models through the Website, creating certain information and economic spaces by means of intellectualized software (multiagent systems or software agents as agents of economic activity) in the global electronic environment or object-oriented software (site, portal, e-mail box, etc.). It is the Web server, a kind of business card of an enterprise that represents a set of interconnected Web pages, presents the company and its services. The homepage of the company website tells you about the history of the company, its profile, projects, products / services, business partnerships, etc., namely, general information about what the organization provides and what offers. This page often has links to portals (multifunctional sites) of e-markets or e-shops, which are the entry points to the global network of all participants of the business process, as well as a place for placing electronic catalogs of goods, services, transaction management, logistics processes, payments etc. Today, Web2 and Web3 technologies are replacing Web technologies. They are based on social networks, a collaborative effort to develop information resources. Corporate blogs, Wiki encyclopedias and others are based on these new technologies.
