ABSTRACT
Supply chain enterprises operate under the influence of many uncertain factors, such as, for example, fluctuations in demand, instability of supply, competitors' activity, weather conditions, etc. These issues in real supply chains are the responsibility of managers or of a provider firm.
When modeling processes in supply chains, coordination and adaptation functions are taken over by the corresponding blocks of the chain model. This study is devoted to the topical problem of improving the efficiency of the chain, taking into account the factors noted, namely, the study of management models for adaptive supply chains.
Due to the stochastic nature of the supply chain environment, modeling typically uses a simulation approach. Studies have shown that models that do not include self-organization blocks are not able to provide the required quality of management in conditions of uncertainty. Therefore, for adaptation at the operational level, it is proposed to consider the agent model in combination with the most appropriate methods of the automatic control theory. The presence of the human factor in supply chain management implies the presence of inertia inherent in people, which determined the applied principles: "quick response" - inertia and predictive nature when smoothing demand fluctuations to control the level of production, a fuzzy logical conclusion as a "soft" regulation inherent in humans, as well as error control based on the PID controller.
The model implemented in the Anylogic program has shown the effectiveness of applying the considered control methods under conditions of uncertainty and stochasticity of the parameters of the external environment. So, for example, the application of the quick response principle ensures the stability of the chain at the given levels of the studied impacts. So, in particular, in the framework of combined management, the model showed the best result - no more than 10% of outstanding orders. The addition of a continuous inventory control module to the model made it possible to reduce the failure rate by an average of 50%. The greatest effect is achieved as a result of the use of integrated control which takes into account the simultaneous change in the parameters of the chain links.
The considered control algorithms can be tested on empirical data of a specific chain, applied in the development of digital twins of chains, used by the provider as a means of automating the real supply chain management.

ABSTRACT
Supply chains developed through participation of foreign suppliers exert considerable influence on countries’ insertion into global value chains (GVCs). Close relationship between supply and value chains makes it possible to use statistical data on GVCs to get complex picture of supply chain dynamics in various economic sectors. The ultimate goal of the research is to uncover and explain specifics of supply chains development in leading oil refining exporting countries based on the value-added statistics.
Analysis of countries’ backward participation in GVCs allows to understand development as well as industrial and regional structure of supply chains, into which national producers integrate as buyers of components. Leading oil refining exporters demonstrate different levels of national production dependence on foreign suppliers. The main factor that influences globalization of supply chains is a presence of advanced oil production industry in the country. World leading oil producers, Saudi Arabia and Russia, depend on foreign supplies to a minimum extent. USA, which are currently intensively expanding oil extraction, reduce offshore deliveries of resources. India and the Netherlands with low oil production volumes as well as Singapore and Korea with no oil extraction at all are forced to supply oil and other oil refining components – chemicals, equipment, machinery, from abroad.
Countries’ forward participation in GVCs together with the statistics on origin of value added in final demand allows to conduct analysis of national companies’ participation in foreign producers’ global supply chains as sellers of components. From geographical point of view consumption of oil refining products, supplied by leading oil refining exporters to the international market, is concentrated in the domestic regions of the countries. This fact indicates the regional character of global supply chains. Supplies of oil refining from the Netherlands and Russia show the highest degree of regionalization, while supplies from the USA and India the lowest. The sectoral consumption of oil refining shows similar structure for all analyzed countries – around half of the consumption occurs in international manufacturing sector, about quarter goes to business services sector, significant role in consumption plays global construction industry.
The research results may be used by companies to make strategic decisions on logistics and supply chains, and by governmental bodies to develop measures to regulate foreign operations of national producers.

ABSTRACT
Today Blockchain technology is one of the breakthrough innovations that changes modern business and can bring it to a new level. Supply chain management (SCM) is one of the areas where this technology can manifest itself in the best possible light. Blockchain is designed to solve one of the most pressing issues of the SCM – ensuring the necessary level of transparency of the chain for all its participants. Every day, business increasingly faces the problem of counterfeiting, complicated document management or the problem of low-quality raw materials, in particular, in food industry. All these problems are a direct consequence of the lack of transparency required by the various scammers and attackers. Blockchain is a distributed and reliable data storage technology designed to solve the problems mentioned above. In this system, all participants have the same rights and access to information, and the system itself works through smart contracts that provide trust between participants. This paper examines the works of various authors and identifies the benefits of Blockchain technology and its application in SCM. In addition, successful examples of the use of this technology in business will be considered.

ABSTRACT
In the environment of increasing market globalization, it is almost impossible for a company to asses strategically competitive business without targeting rationalization approach and optimization of logistics costs reflecting attractiveness of pricing policy of a company's business. In this case, the logistics cost management should be included in the set of parameters, determining the most investment appealing business. Foreign developments in the presentation of an effective business model, in general, describe the increasing role of logistics in creation of strategically viable business, without introducing the author's concepts in the vision of logistics in the business model.
As a result of building a determinant model of factor components of effective logistics cost management, we can identify and analyze key systematic characteristics, the management of which enables to influence a client's value of business, increasing competitiveness and attractiveness. The analysis of the results of logistics cost management within the framework of a business model of Russian enterprises made it possible to update the management policy towards enhancing the integration of the entire business chain; organize effective logistics management structure; improve the accuracy of planning strategy and forecast the integrated supply chain; increase investments in the automation and informatization of the business processes.
