The paper considers several methods of analyzing opportunities for optimizing supply chains. An iterative method of finding the optimal structure is proposed, considering the power of the supply chain links and the capacity of the paths between them. The theorem on the value of the maximum flow in the combined path is proved. A numerical simulation...

Перший клас задач є NP-складним для пошуку точного рішення, який базується на припущенні...
With the rapid advancement in our civilizationʼs technology, the dynamics of a variety of global processes are on the rise as well, the environmental degradation rate increases, competition for access to resources grows, new large-scale epidemics emerge, etc. All of these processes and phenomena have a negative impact on global security and are bei...
The functioning of supply chains is associated with a constant response to stochastic fluctuations within a particular cycle. The ability to respond to uncertainty in the cycle is required to ensure the quality of the supply process. The task of determining resource capacity to respond to uncertainties in supply chains is an urgent task for manager...
The article considers the method of finding solutions in the dynamic model of inventory management under uncertainty. An algorithm for formulating an optimal inventory management strategy is proposed using the developed method of determining the size of the optimal order lot and forming an optimal supply plan under conditions of stochastic demand....
The flow of inventory items within the supply chain has a probabilistic parameter of process [1]. The number of process states can be either finite or infinite. The state of the development parameters of the process fully depends on the parameters the previous process, that is, there is a pronounced consistent process flow. It is possible to level...
Due to the instability of the sales market, fluctuations in consumer demand are possible. Even small changes in demand can lead to major changes in orders placed further up the supply chain. An important factor affecting the volume of sales is the presence of substitute goods. A change in the characteristics of one product can affect the sales volu...
The work considers modern methods of determining the current state of the dynamic system of Supply Chains; the article deals with system behavior that has an iterative threaded system; simulation of the behavior of a dynamic system is demonstrated, which allows obtaining sufficient conditions for the system's resistance to noise.
In Ukraine, the safety of nuclear power plants depends significantly on human factors. At the same time, the results of the development of cybernetics, informatics, automation, computerization, robotics, digitalization, and artificial intelligence testify to the possibility of reducing the adverse impact of human factors on high-tech processes. The...
Purpose. In the information era, the issues of data science, which began as statistical processing of quantitative observations, are gradually transformed into the issues of smart processing of various information and artificial intelligence. At the same time, the processing of large information arrays will require system engineering.
While data ca...
The relevance of building a high-quality customer profiling process and
sales forecasting using recurrent neural networks using the LSTM-method is
considered. The limitations in the process of using forecasting methods and the
limitations of recurrent methods are described. Recommendations for eliminating the
restrictions are given. A brief des...
The globalization of world trade has led to increased competition in all types of markets. Increasing competition affects both supply and demand. Developed communication networks have a positive effect on the availability of new manufacturers and suppliers, reduce supply chains, and this, in turn, contributes to the development of logistics routes.
The method of determining the stability of the bandwidth function of nodes in supply chains is considered. The method involves the decomposition of the total flow function, which determines the maximum possibility of processing the flow node on the components and further determine the limitations of the overall supply system within a particular sup...
A method for determining the stability of the throughput function of nodes in supply chains is considered. The method provides for the decomposition of the total flow function, which determines the maximum ability of the node to process the flow into components and further determines the restrictions of the overall supply system within a certain su...
As of 2021, there are 12 positions in the Forbes ranking of the top 100 in Ukraine held by representatives of the information technology industry, which got the education in modern universities of Ukraine. These positions are strengthened with taking into account the new capitalization of the Revolut neobank and the GitLab transnational corporation...
One of the main criteria for planning and evaluating supply chains is the indicator of the flow capacity, which affects the structure of the supply graph, terms of supply, risks, opportunities and the need to differentiate supply channels. The paper analyse an algorithm for calculating the optimal value of the flow in supply chains, taking into acc...

The rapid growth of the world's population, together with the sharp acceleration of industrial production in many parts of the world, has provoked unprecedented changes in the natural environment. As a result, in Ukraine the issue of the quality of the water supply process performed by the monopolist - government agencies, ie the consumer does not...
Introduction. Optimization can be applied in developing profitability management tools for a cloud service broker working according to a certain business model. On behalf of the managing telecommunications holding company (telecommunications operator), this broker integrates, aggregates and configures software and data storage services of third-par...
Supply Chains are complex dynamic processes. These processes are characterized by the presence of a probabilistic component that negatively affects the chain administration process. The process of optimizing supply chain management and development is becoming a key issue in modern organizations. The use of mathematical modeling methods allows you t...
