Increasing the productivity and efficiency of agricultural cargo transportation in the agro-industrial complex of the Russian Federation is achieved through the use of tractor trains consist-ing of tractors and trailer links, the main of which are trailers. This method allows you to ensure the quality and safety of agricultural goods, as well as reduce the cost of transportation. During the analysis of the known designs of tractor-trailer dump trailers, it was revealed that a character-istic drawback is the imperfection of the design of the locking elements of the platforms designed to fix them on the chassis. As a result, a promising technical solution was developed, which, in comparison with the known ones, has a simple design and increased efficiency when fixing the bodies on the chassis. The article describes the design and the principle of operation of this tech-nical solution. The results of the structural strength calculation are presented. The conducted check showed that the obtained value of the safety factor, equal to 2.2, will ensure the operational reliability of trailed dump vehicles. The results of the study are recommended to both domestic and foreign research institutes, design and production structures of the automotive industry for further study and refinement of the proposed device with a view to its possible implementation in practice.

Purpose The purpose of this paper is to review and analyze the recent sustainability assessment studies in the manufacturing industry from the triple-bottom-line (TBL) perspective. This paper aims to depict the status quo of practical sustainability assessment, summarize the different levels and boundaries of evaluation, and highlight the difficulties and further improvements needed to make the assessment more effective in the manufacturing industry. Design/methodology/approach Four keywords, namely, sustainability assessment, sustainable manufacturing, TBL and green production, were used to explore and find the relevant articles. First, this paper systematically reviewed the studies and analyzed the different levels and boundaries of sustainability assessment. Following this, the reviewed studies were critically discussed along with their merits and shortcomings. Findings The review showed that most of the sustainability assessment studies were conducted on product, company and process levels in the manufacturing industry. Nevertheless, there is still a need to focus more on plant and process level assessments to achieve the TBL objectives. Environmental assessment is comparatively matured in manufacturing industries. However, from the economic and social viewpoints, only cost analysis and workers’ safety, respectively, were considered in most of the studies. The economic and social indicators need to be more inclusive and should be validated and standardized for manufacturing industries. Originality/value Unlike previous sustainability assessment reviews in manufacturing industries which were mostly based on life cycle assessment, this paper has included environmental, social and economic aspects in one comprehensive review and focused on recent studies published from 2010 to 2017. This paper has explored the recent sustainability assessment trends and provided insights into the development of sustainability assessment in the manufacturing sector.

Increasing manufacturing complexity continues to be one of the most significant challenges facing the manufacturing industry today. Due to these rapid changes in manufacturing systems, one of the most important factors affecting production is recognized as the frequent production setup or changeovers, consequently affecting the overall production lead times and competitiveness of the company. Developing responsive production setup and process capability is increasingly important as product ranges and varieties in manufacturing companies are growing rapidly and, at the same time, production business models are operating more towards being customer-oriented. Furthermore, although different conventional methods have been used to manage complexity in production changeovers, sustainability and competitiveness development in a manufacturing company needs to be scientifically addressed by managing manufacturing complexity. In this paper, a sustainable manufacturing-oriented approach is presented in mind of managing manufacturing changeover complexities. A case study is carried out specifically concerning changeover complexity in a pharmaceutical company, aiming at minimizing complexities in production changeover and waste, increasing plant flexibility and productivity, and ultimately the sustainable competitiveness of the company in managing manufacturing changes.

The present research featured the illicit trade in Russian gold and silver coins in Xinjiang in the 1850's. The paper focuses on the problems of control and customs services, as well as on the difficulties connected with the trade in Russian goods. The historical analysis was based on the documents written by Konstantin Adrianovich Skachkov, the then Russian Consul in Chuguchak. The materials were obtained from the Research Department of Manuscripts of the Russian State Library. In his report, Consul K. A. Skachkov compared the state of the markets of the Russian-Chinese trade in Chuguchak and Kyakhta. He highlighted the broad prospects for trade development in Xinjiang. The Consul paid great attention to the problems on the young market of Central Asia and proposed some measures to improve the situation. He performed a comparative analysis of the trading activities of a Russian merchant and a smuggler. The analysis makes it possible to reconstruct the trading process, determine the cost of transportation, and formulate the commercial benefit resulting from the legal trade and the contraband trade. K. A. Skachkov concluded that despite the high potential for trade development, the region was torn apart by substantial internal contradictions and demanded greater attention from the government. The illicit trade in Russian coins was caused by the barter trading on the Xinjiang market in 1850's.

Demand for low-tonnage transportation of LNG requires improved logistics. Assessing the value of all parts of the supply chain is an important component of solving the problem of optimizing transportation costs for both consumers and LNG suppliers. In connection with tightening of environmental requirements regarding bunker fuel, the task of optimizing the supply of LNG for water transport by the cost of transportation becomes particularly relevant.The objective of the study is to develop a universal approach to estimating the cost of transporting low-tonnage LNG for bunkering vessels in the Russian Federation.The research methodology is focused on the analytical method based on a system-structural approach.As part of the departmental project of the Russian Ministry of Industry and Trade «Development of  gaspowered fleet for navigation in coastal waters and inland waterways», the authors developed technical and economic models for calculating the unit cost of LNG transportation by road and water. To calculate the unit cost of LNG transportation by rail, the data of TMkarta information and reference system were used. Based on model calculations and data of TMkarta system, regression relations were obtained that allow one to determine the cost of transportation for various options of transport and technological schemes based on a limited set of parameters. An approach has also been proposed for estimating the cost of LNG transshipment. The regression ratios were tested for selected routes. As a result,conclusions were drawn about the most effective LNG transportation options.

In the existing logistics distribution methods, the demand of customers is not considered. The goal of these methods is to maximize the vehicle capacity, which leads to the total distance of vehicles to be too long, the need for large numbers of vehicles and high transportation costs. To address these problems, a method of multi-objective clustering of logistics distribution route based on hybrid ant colony algorithm is proposed in this paper. Before choosing the distribution route, the customers are assigned to the unknown types according to a lot of customers attributes so as to reduce the scale of the solution. The discrete point location model is applied to logistics distribution area to reduce the cost of transportation. A mathematical model of multi-objective logistics distribution routing problem is built with consideration of constraints of the capacity, transportation distance, and time window, and a hybrid ant colony algorithm is used to solve the problem. Experimental results show that, the optimized route is more desirable, which can save the cost of transportation, reduce the time loss in the process of circulation, and effectively improve the quality of logistics distribution service.

The purpose of this article is to compare major infrastructure projects of the water transport connection between the Caspian Sea and the Azov-Black Sea basin –the «Eurasia» canal and the «Volgo-Don 2» canal on the following parameters of comparison: the height of the watershed, the length of the canals, water supply of canals, the conditions and intensity of navigation. The need to build a new shipping canal is due to the projected increase in the volume of cargo transportation from the Caspian Sea that will cause difficulties in the existing Volgo-Don canal. The authors of the study have analyzed and summarized the research materials containing information about the design decisions on the «Eurasia» canals and the second branch of the Volgo-Don shipping canal. Realization of the project canal «Eurasia» will significantly decrease the delivery time of cargoes, including oil from the Caspian Sea and Central Asian countries to the Black and Azov sea; cut the cost of transportation between these regions in comparison with transportation by «VDSC2» (by reducing the length of the waterway); increase in the strategic plan the reliability and safety of water transport links of the two seas basins on parallel directions; create conditions for socio-economic and industrial development of the canal region s. adjacent to the track. In the case of «VDSC-2», the following prospects for construction are highlighted: to ensure the passage of the additional cargo flow expected in connection with the growth of industrial production in Russia in recent years and the corresponding increase in the traffic of industrial and agricultural goods by water transport; to strengthen Russia’s political and economic infl uence on the countries of the southeast region and the European community; to intensify the development of the domestic shipbuilding to create a specialized fl eet for effi cient operation in the conditions of international transportation on internal and external waterways; to increase capacity and, consequently, the economic efficiency of the operation of international transport corridors «North-South» and «East-West».
