Heading:PROBLEMS AND OPINIONS

Problems of digital transformation of logistics systems and supply chains

Annotation. The article considers the main stages of digitalization of economic processes, systematizes the stereotypes of the concept of «digital economy». Based on the analysis, new business practices are systematized. The factors that determine the complexity of digital transformation in logistics systems at all levels are identified. The task of process integration of information systems of logistics companies is formulated. The conclusion is made about the prospects of using process-oriented integration of information systems in logistics.

Assessment of the goods movement delay along the transport corridors of the national logistics system

Annotation. The article offers a mathematical model of cargo movement along the selected section of the national logistics system, which shows how to calculate the damage caused by the impact of adverse events in the process of cargo transportation on a specific section of the chain. The model estimates the amount of cargo delay when moving along the selected route. Based on this, the damage can be calculated as a function of the value of delay in transit, and decisions can also be made to change the terms of contracts and conditions of transportation organization.

Methodological approaches to the decomposition of the logistics system of a manufacturing enterprise

Annotation. The article discusses the main approaches and the sequence of actions in the decomposition of the structure and functions of the logistics system of a manufacturing enterprise. The features of the logistics problems of the enterprise and the proposed ways of their solution using the principles of logistics are determined.

Key words. Logistic system, analysis, synthesis, logistic function, logistic operation.

Identification activities in logistics as a factor of sustainable development of the transport sector

Annotation. The analysis of the significance of identification activities in the logistics system of goods movement for the sustainable development of the transport sector in the new economic conditions associated with global trends and regional features. Data on the use of identification systems for photo and video recording of traffic violations, ground passenger transport management, automated traffic management, traffic safety, road safety and diagnostics, and incident management are presented.

On the approach to solving the problems to optimize the infrastructure of the region

Annotation. The article proposes an approach to solving the problem of optimizing the regional logistics infrastructure. The proposed algorithm, considered for the particular case of the problem with single-product flows and two types of vehicles, can also be used for a multi-product model, with various types of heavy and light transport.

Key words. Infrastructure, a network of car fleets, distribution and sub-sorting warehouses, stochastic model, probabilistic demand, two-tier planning, minimum cost flow.

The concept of proactive management of transport and logistics systems

Annotation. Engineering, as a multidiscipline, is one of the subject areas of systems and software engineering, with the help of which a holistic approach is implemented throughout the entire life cycle of a logistics system. The digital environment creates conditions for the integration of transport and logistics processes with electronic document flow, which contributes to more efficient management methods using digital platforms, and the architectural approach makes it possible to integrate the supply chain based on the homeokinetic plateau mechanism.

Formation of a targeted offer of orders in logistics by using collaborative filtering

Annotation. The article deals with the management of order processes in the formed and newly formed product markets. The classic version of managing the order procedure and calculating the optimal batch and type of product is considered, with the transition to solving the problem of inventory management throughout the supply chain, taking into account its configuration. The calculation of the optimal order size is presented in terms of methods and models for solving the problem of organizing deliveries in order logistics and inventory management.

The establishment of a national logistics platform

Annotation. In the article the analysis of creation of a national logistics platform in the Russian market was carried out. The architecture of the logistics platform and its main components are considered. The target business model of the logistics platform is shown, as well as its limitations on the Russian market.

Key words. Business model of national logistics platform, logistics platform, platform advantages, platform limitations.

Socio-economic aspects of implementing the blockchain platform in the international trade turnover

Annotation. This article describes the current global trade trends, reveals the problems and features of international multimodal transportation information exchange in the context of the digitalization of the economy, highlights the main effects of the transition to a new blockchain based information exchange system for large groups of participants in international cargo exchange participants, combined in groups according the common needs.

Key words. Digital economy, logistics, international economic activity, multimodal transportation, information systems.

Evaluation of the Product Demand Influence on the Functioning of Logistic Infrastructure Elements

Annotation. This paper examines the impact of changes in some parameters of models describing demand on the solution of the problem. It is assumed that the distribution functions of random variables describing demand are unknown, but their mathematical expectations are known. The generalized problem is posed as a discrete programming problem with nonlinear separable functions. For an approximate solution of the problem, its continuous relaxation is performed.
