Published: October 2020

Abstract
An experimental method was obtained for treating semi-finished products from titanium nickelide alloys TN-1 by twisting a cylindrical sample in the austenitic state at a temperature of T = 493 K to a predetermined angular strain, after which the sample was rigidly clamped, fixing the angular deformation of the sample, and cooled to a temperature of T = 293 K. At a given temperature, the rigid jamming of the sample is eliminated, while the isothermal return of the part of the deformation obtained by twisting in the austenitic state occurs. Then the sample is heated to a temperature of T = 493 K, and there is a shape memory effect (SME), manifested in the form of restoration of angular deformation. A systematic experimental study was carried out of the dependence of the influence of the complex regime of thermal-mechanical action containing the stages of generation and relaxation of stresses on the shape memory effect. It has been experimentally established that SME during heating after cooling in the direct MT range under pinched conditions can be observed with zero deformation effect in the final heating interval.

Abstract
Currently, in the Siberian region of the Russian Federation, thermo-time processing of the melt and the technology of resonant-pulsating refining of metal are widely used. The article highlights the results of the development and implementation of thermo-time processing and resonant-pulsed refining to improve the properties of the metal. Thermo-time treatment, as a rule, is carried out in induction and electric arc furnaces. It was found that thermo-time treatment allows to significantly improve the quality of the metal, improve the mechanical properties of the products. Resonant-pulsating refining combines melt processing with argon purge and vibrational frequency spectrum processing. The impact of this type of metal blowing on the gas content, the microstructure of cast iron, its mechanical properties, and also the operational properties of the products obtained is evaluated. It was established that the strength properties of cast iron increased by 40-65 MPa, hardness increased by 20 to 30 HB, density -by 100-300 Kg/m3. In addition, it should be noted that the use of the technologies presented in the work can significantly reduce the harmful effects of phosphorus. The operational durability of cast iron products has reached the best domestic and foreign indicators. The developed technologies allowed the implementation to achieve the best performance in the industry with minimal cost. These technologies can be widely used in foundries, electric steelmaking and oxygen-converter shops.

Authors: Varenik K A , Varenik A S , Kirillov A V , Shuvalov M V 
Published: October 2020

Abstract
The purpose of the experimental studies was to verify the reliability of the method for solving the stability problem of centrally compressed rods, taking into account the creep of wood. To achieve this goal, it is necessary to have a diagram of deformations of real wood and experimental data on the behavior of rods of the same wood under continuous load. Experimental studies include short-term axial compression tests of small specimens with recording of load-deformation diagrams, as well as short-term and long-term tests of cores of different flexibility for central compression, the description of which is presented in this article. The authors of the paper obtained the values of critical stresses under longitudinal bending for wooden rods with different lengths and flexibility. These results have a high convergence with the values obtained as a result of theoretical calculations.

Abstract
The paper considers the sustainability of the digital and industrial technologies interaction. Based on the analysis of existing studies on the introduction of innovative digital technologies and cyber-physical systems, it was realized that in the conditions of intelligent technologies joint implementation unstable states of the system are inevitable, and continuously monitoring of the system sustainability is essential. The expediency of applying the laws of the theory of open systems proposed by L. von Bertalanffy, A. Hall, and others to substantiate the managing sustainability appropriateness of the enterprise cyber-physical system is given. The quantitative estimates based on the information approach of A.A. Denisov are proposed, which allow to assess the degree of system’s integrity. System’s integrity degree ensures sustainability of a system, on the other hand, freedom of system’s elements ensures the system development. The proposed estimates can be used for accessing the influence of digital technologies on the implementation enterprise strategy, ensuring the effectiveness of its development and increasing competitiveness based on the digitalization of production and management while maintaining stable functioning.

Published: October 2020

Abstract
Improving cyber security is the purpose of all states. Military-industrial complex is in need of creating innovative protection systems for their cyber space. A lack of such security systems can lead to the global disaster, using nuclear weapons. Today’s legal regulation of the national personal data still does not provide for legal regulation of user data which can be obtained via gadgets fitted with cameras, speakers, applications. Apart from information leakage as a result of hacker attacks, and accidental cyber leaks, the great problem is related to unlawful leakage and data stolen by company employees. Although the legislation of personal data protection is improving with allowance for precedents in this sphere leading to cybercrimes, an amount of unlawful use of personal data by company employees do not decrease due to a lack of accountability and behavior code in the sphere of personal data processing.

Published: October 2020

Abstract
International Facility Management Association (IFMA) traditionally divides the management of real estate into asset, property and facility management. The paper explores how the emergence of building information modelling (BIM) has influenced the distribution of information about the building among the stakeholders. As-built BIM in industrial buildings is a significant part of digital transformation of industrial assets and emergence of Industry 4.0. The tendency of transferring the ownership of information from facility manager to asset manager as well as the increase of transparency is analysed in the recent literature. The development of as-built BIM has given the possibility to the owners of real estate to become not only the owners of the assets themselves but also the owners of digital assets. In order to clarify current situation in the scientific community, the research interest in building information modelling among the studies mentioning facility management, asset management and property management has been analysed. The role of information about the building components as well as practical examples of operational expenditures reduction are explored and discussed.

Published: October 2020

Abstract
The paper is dedicated to analyzing the process of innovative product development in the chemical industry, elaborating a methodology for evaluating the efficiency of innovative projects common for this sector of the economy, and testing this methodology using the example of a project. First, the authors consider the specifics of the development process in which a new product is created in the chemical sector. The emphasis is laid on the product-process approach, and a brief characteristic of this approach is provided. Then the authors discuss the general methodology of product development in the chemical sector using investment analysis methods and a decision tree. Then the authors tested the methodology using the example of a Russian chemical enterprise realizing an innovative project on production of urea-formaldehyde concentrate, urea-formaldehyde resins, and phenol-formaldehyde resins. The results of the investment attractiveness of the project demonstrate that the net present value from the implemented project, given the risk factors, is higher than if the project was implemented with the basic initial conditions. The elaborated methodology allows us to evaluate investment projects in the context of uncertainty, and the result of its application is that more informed management decisions about investment projects in the chemical industry become possible.

Published: October 2020

Abstract
Digitalization of tourism in the Russian Federation is primarily associated with the increasing importance of tourism, not only as a way to spend leisure time, but also as a branch of the economy that can generate a significant income and ensure territorial development. Despite a large number of diverse tourism resources in the country, tourism development was highly uneven, concentrating in a limited number of regions.
Information technology and especially the Internet has greatly toughened global competition over tourist flows. In today’s world, tourists would rather visit a place about which they can get sufficient information and where a trip can be easily arranged. The role of national and regional tourist web portals, supported by relevant government agencies, is significantly increasing in this context. The tourist information infrastructure should not only provide up-to-date and complete information, but also ensure usability for the tourist (including independent). Tourism within St. Petersburg and Leningrad Region is featured by rather close links between the regions and unification of tourist flows between them. Both regions have a significant quantity of tourist resources, which ensures development of various types of tourism. Creation of the ‘silver Necklace’ interregional route consolidated further integration between tourist resources of the neighboring regions. Tourist portals of these regions, nevertheless, significantly differ in their content and interactive capabilities. As part of the study, the information presented on tourist portals of Russia, St. Petersburg and Leningrad Region in terms of implementing interactive services was reviewed.
The Formation of Partnership Model in Supply Chain Management
Authors: Suvorova Svetlana , Tevanyan Anna 
Published: October 2020

Abstract
Supply chain management is a complex and systematic process of moving commodity flows from the moment of production planning to the further distribution of products in accordance with the market conditions and the target segment requirements. Meanwhile, the effectiveness of the supply chain can be achieved through the formation of partnerships that are aimed at organizing comprehensive cooperation of economic entities with its inalienable integration into the logistics chain of their own production. Also, such partnerships are based on the desire of economic entities to concentrate the required resources in the area of the irown competence, whereas to delegate the other functions to the third-party enterprises (for example, outsourcing them). In order to establish a partnership, the parties involved must determine and agree on possible motivators, contributing factors, business process components and expected results, taking into account the balance of power, specialization, readiness for cooperation of stakeholders, possible damage and distribution of risks, importance of the applicant, reasons for withdrawal from the contract and “force majeure” circumstances. This proposed model of partnership in supply chain management allows reducing the production cycle, the maintenance costs and the “money-money” cycle. It also allows improving the performance of the supply chain, optimizing logistics costs, which, in turn, creates favorable conditions for reducing foreign economic costs, increasing profits and focusing the core competencies of the enterprise-manufacturer.

Published: October 2020

Abstract
The growth of market competition, its transition to regional and international levels, the development of information technologies as well as dramatic changes in consumer behaviour determine the development of global market trends, which necessitates the study of a methodology to form distribution channels, from the viewpoint of digital connectivity and transition to a more complex global system. The paper discusses the conceptual framework for creating a digital business ecosystem as a combination of three components: the consumer’s ecosystem, the producer’s ecosystem and the communicative connecting core. The object of research is a distribution system that operates in a market environment. The research is based on the application of the descriptive-analytical and comparative methods as well as the method of semantic and structural analysis, the method of monitoring the content of terminology in theoretical and applied papers within the chosen field of study. Significant development trends have been identified in the theory of global value chains and supply chains, the strategic goal of which is not to dominate, but to keep the balance that generates added value. The ecosystem formation theory terminology is enriched by introducing the concept of “a digital ecosystem” into the scientific circulation. The role of the consumer as a full participant in the business ecosystem, who is engaged in the process of creating additional consumer value, is determined.
Development of a Reference Model for the “Purchase” Business Process as an Element of Modeling Basic Business Processes at FMCG Chain Retailing Companies
Authors: Khareva Viktoria , Voronova Olga , Khnykina Tatyana 
Published: October 2020

Abstract
The article presents the development of a reference model for the “Purchase” business process as an element of modeling the basic business processes at FMCG chain retailing companies. In many ways, the rationale for the development of a business architecture model is related to the understanding of factors that push chain companies to search optimization solutions in terms of organizing their work. In these conditions, modeling basic business processes of the company is essential for the construction of architectural solutions of FMCG retail network companies. The models are based on a hierarchical principle that allows to consistently move to the next level of detail, as long as the model is not described in as much detail as necessary to solve specific problems of FMCG chain retailing companies. In accordance with the aim of the study, the basic business processes of FMCG-retail network companies are identified, a typical structure of the “Purchase” business process is presented, a contextual chart of the top level of detail and a subsidiary model of the “Purchase” business process are consistently developed (the IDEF0 notation is used in this study). On the basis of top-level models, models of subprocesses of business process A1 “Purchase” are developed: A1. 1 “Purchasing planning”; A1. 2 “Choice of Suppliers; A1. 3 “Conclusion of the Contract with Supplier”; A1. 4 “Operational management of Deliveries”; And 1.5 “Assessment of suppliers”. The developed models can be used in construction of architectural solutions in FMCG chain retailing companies.

Published: October 2020

Abstract
In this paper, we study the trends of investment attractiveness of trade in Russia, connected with unfavorable social and economic factors of recent times, are studied. The analysis shows that despite its high practical significance, the concept of an “innovation and investment project” does not have a commonly accepted scientific definition. There is neither a unified approach to understanding this term, nor a holistic view of the problems and tasks that need to be addressed during the implementation of such projects. An analysis of the concept of an “innovation and investment project” has made it possible to identify the shortcomings in the existing interpretations and to propose a new one. Based on the analysis of systems for innovation and investment project management, we identify the advantages and disadvantages of these systems, and propose a model for a basic system for innovation and investment project management, including: principles, methods, tools for its implementation.
