As the e-commerce market develops it has been gradually consolidating. More and more e-marketplaces appear over time. They unite a number of internet-retailers, significant part of which is represented by small and medium enterprises. Active growth of e-marketplaces poses new challenges for the e-commerce logistics. Great number of parties (both consumers and sellers), constantly growing assortment range, different models of interaction with suppliers, in combination with ongoing geographical expansion, have been considerably complicating e-marketplaces logistics support.
The author of the paper suggests the classification of e-marketplaces, conducts comparative analysis of the biggest electronic retail platforms operating in Russia, studies typical issues of their logistics activity, examines the opportunity of the horizontal collaboration mechanism's application to tackle some of these problems. By applying the methods of comparative analysis, classification, analogy, as well as the methods of horizontal collaboration, the author has gained the following results:Defined the factors influencing complex nature of the e-marketplaces logistics compared to the logistics activity of pure internet retailers Formulated conditions under which horizontal collaboration at the e-marketplaces can be used in the efficient and effective way Proposed options for the distribution of the groups of functions between the participants of the horizontal collaboration project (internet retailers, marketing intermediaries specialized in introducing products to different virtual platforms, e-marketplace, logistics service providers, banks and/or fintech companies, project curator ensuring the parties interaction) Suggested application of the Shapley vector method to share the gains of the e-marketplace's sellers collaboration.

The article explores the problems of eliminating abnormal undesirable situations that arise when optimizing solutions according to many criteria in logistics research, which correlate with the phenomena of inadequate choice. For the task of multi-criteria route selection, problems of eliminating phenomena of this type are discussed and special procedures for identifying these phenomena are used. For the first time, a comparison is made of the effectiveness of eliminating the phenomena of inadequate choice based on the transition to generalized data and on the basis of a synthesis of the processes of the analytical hierarchy with the procedures of traditional selection criteria. It is shown that both approaches successfully eliminate the phenomenon of inconsistency in the nature of indicators of particular criteria. At the same time, it was proved that the transition to generalized data cannot guarantee the elimination of the phenomenon of inconsistency in the order of values of particular criteria: the corresponding situations can nevertheless manifest themselves in an implicit form. An exception is the criterion of works, which effectively eliminates the phenomenon of inconsistency in the order of values of particular criteria, both on the basis of a transition to generalized data and on the basis of a synthesis of the processes of the analytical hierarchy with traditional selection criteria

The article considers the logistics chain, consisting of a supplier and customers, as are chosen distributor and a few dealers. The goal is based on probability theory to describe the nature of the effectiveness for introduction of VMI-technology and to analyze the dependence of the efficiency from the structure of the chain.
For mining enterprises, the need for spare parts and consumables used in the repair and operation of equipment depends on a number of factors, and the degree of influence of each of them is not unambiguous and has a more probabilistic (stochastic) nature. Therefore, the recommendations of the equipment manufacturers, which are present in the technical documentation, are more general (universal) in nature. In circumstances where it is not possible to unambiguously determine the actual need for operating resources, mining companies are forced to form additional insurance stocks necessary to ensure an uninterrupted production process and maintain productivity at a given level. To reduce the negative impact of uncertainty of the environment, it is advisable to build relationships with suppliers based on VMI technology. The calculations were made taking into account the total costs associated with the organization of orders and supplies from suppliers and consumers. The proposed solutions were based on using the model of the optimal order size in the supply chain, taking into account losses, both from immobilization of financial resources diverted to inventories, and from downtime of technological equipment. The article proposed a list of items of expenses that should be taken into account when calculating the total costs associated with purchases and stocks of operating resources of mining companies. As a result of calculations in the article, it is shown that with the development of VMI relations between mining companies and their suppliers, it is possible to achieve a mutual cost reduction, while reducing inventory levels, by increasing transparency and certainty when planning the demand.
The major market for crude oil produced in the Caspian region and petroleum products produced at the southern refineries of Russia and CIS countries is the market of the countries of the south of Europe. The transport infrastructure of the countries of the south of Europe for delivery of oil products to consumers is designed for sea supply. In this work, special attention is paid to the condition and development of port terminals and transport systems connecting port tank farms with consumers of oil products. The main capacity of the oil industry in the south of Europe is concentrated in the most developed countries. The method of quantitative analysis is used to study the possibilities of transport infrastructure and the production of petroleum products in the region under study. With the help of this method it is possible to establish the correspondence of the possibilities of the transport infrastructure with the expected and existing freight flows. An analysis of the capabilities of oil refineries that consume crude oil in this region is given. The possibilities of enterprises providing reserve capacities of oil energy resources are considered. Based on the data for the last decade on oil consumption and refining in the countries of the region, the tendencies of development of supply chains for the oil industry in the south of Europe are being investigated. The main regions of crude oil consumption are outlined, the prospects for the development of oil production in the countries of southeast Europe are shown. The presented analysis makes it possible to identify the most significant areas of southern Europe for the implementation of oil supply chains in the region, to build the most efficient cargo flows for shippers.
Authors demonstrate that arising disbalance of supply and demand generates the set of problems for the business organisation, such as high order periods, loss of clients in case of shortage, high total costs, and low efficiency of industrial lines. Eventually, all this factors essentially influence on achievement of company’s strategic goals and undermine corporate market image. Because of developing of integration and cooperation in supply chains, increasing attention in business organisations is given to technology «joint planning of sales and operations/production» (Sales and Operations Planning – S&OP). Article’s purpose is to analyse, how implementing of S&OP technology will affect on solving of mentioned problems (on the example of «Huhtamaki C.I.S.» company). The meaning of planning of sales and operations is made out as a cycle of meetings (stages) repeating in the same sequence every month and subordinating a making decision process.

The paper contains the results of the study conducted by the author on the systematization and formalization of specialized approaches to managing supply chains of leading metal companies and their relationships, comparing these processes with the standard supply chain management models SCOR + CCOR + DCOR and GSCF. The analysis formalized the main directions of development of the methodology of supply chain planning in terms of adapting to the specific of metals including: the reorganization of relations of existing planning processes in accordance with best practices in the industry planning; consolidation of models CCOR, SCOR and DCOR in a single system of supply chain planning processes; refinement steps of the planning process, and the introduction of additional, if necessary; formalization of methods and planning models; definition of requirements for information technology support. It was noted that the requirements for systematization and development of the planning methodology are defined by the needs of its application to ensure the competitiveness of Russian metal companies in a tough fight in the global market.
Within the framework of the digital economy development in Russia, one of important areas is «digital logistics/ supply chain». In the market of freight and passenger traffic the use of digital technologies gives a competitive advantage, therefore their implementation is becoming inevitable for the entire logistics industry. This article considers trends, advantages, prospects and barriers to the implementation of digital technologies in the Russian Federation; the main types of these technologies and their influence on logistics business processes efficiency. A scheme for digital technologies (Big Data, IoT (Internet of Things), Blockchain, Cloud Services, 3D Printing) using in the supply chain are also presented. This paper provides the analysis of digital technologies use impact and a methodology for assessing the relationship with the components of the model of total logistics costs (TLC) in supply chains. It should be noted that proposed TLC model does not only include logistics operations costs, but also the costs associated with complete customer satisfaction.The use of digital technologies in logistics makes it possible to increase efficiency,precision and speed of logistics operations, however it requires significant financial investments, personnel training, accounting long-term physical movement over long distances, problems of customs clearance and terminal handling of goods.
The article deals with some aspects of systematization and classification of various inventory management models with an account for stock-out. The model with «loss of requisition» most rarely encountered in the theory of inventory management, but indisputably relevant because of its practical value, is discussed. The urgency of the stock-out problem in the modern world economy is accounted for by the information given in the article about the losses caused by the stockout. Applying analytical approach when solving the stock-out problem can serve as a tool that will help solve long-standing problems of stock-out costs reduction. In this paper the calculation examples for key variants of stock-out models are given, and, the model with «lost demand» and its connection with a static problem is of particular interest. Calculation results comparison revealed the fundamental difference in models, which allowed to avoid mixing models that is often encountered in the literature. The result obtained during the research is the expansion of the approach to classification, and consequently, the opportunity to attract additional tools of the stock management theory to solve the stock-out problem, which ultimately aims at optimizing total logistics costs.
