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.

Recursive Estimators

This paper is concerned with a discrete time, discrete state inventory model for items of changing quality. Items are assumed to be in one of a finite number, M, of quality classes that are ordered in such a way that Class 1 contains the best quality and the last class contains the pre-perishable quality. The changes of items' quality are dependent on the state of the ambient environment. Furthermore, at each epoch time, items of different classes may be sold or moved to a lower quality class or stay in the same class. These items are priced according to their quality, and costs are incurred as items lose quality. Based on observing the history of the inventory level and prices, we propose recursive estimators as well as predictors for the joint distribution of the accumulated losses and the state of the environment.

The purpose of the study is to group the countries of the world according to the availability and legality of abortion and to identify patterns of development of tourist flows of abortion tourism. The research methodology includes a system of methods and techniques: monographic method (used to process materials from literary sources and Internet resources), statistical method (used to assess the prevalence of abortion), cartographic method (used to visualize the legality and availability of abortion around the world), classification method (used to group countries according to the criterion of the level of availability and legality of abortion). Research results. The geography of tourist flows of one of the types of medical tourism (abortion tourism) was analyzed. It arose as a result of the possibility of obtaining medical procedures abroad, prohibited or restricted in their own country. Attention was focused on the factors of legality and accessibility of these medical services in the countries. There are four groups of countries on the availability of abortion: 1) freedom of abortion; 2) abortion for medical and socio-economic reasons; 3) abortion for medical reasons and in other exceptional cases; 4) complete ban. The right to terminate a pregnancy at the woman's request is guaranteed in 71% of developed countries and in 16% of developing countries. Most countries that restrict abortion throughout the territory or in its separate administrative units - this is the state of Africa and South Asia and Latin America. But abortion tourism is the most intensive in Europe. The controversy over abortion has not abated. The two main groups in discussion call themselves "for choice" (with an emphasis on women's right to choose) and "for life" (with an emphasis on the unborn child's right to life). The scientific novelty of the work is that the proposed grouping of countries according to the legality and availability of abortion, outlines the factors of abortion tourism. The main directions of tourist flows of abortion tourism in Europe are determined. The practical significance of the results of the work is that they can be used to shape the tourism policy of Ukraine, as the state is involved in the field of abortion tourism as a recipient of tourist flows. The results of the study also contribute to solving social and demographic problems in the context of depopulation and deteriorating public health. After all, abortions are factors that negatively affect the reproduction of the population and women's health.

An analysis of modern approaches to improving the efficiency of the car fleet and the competitiveness of railway transport in the transport market of Ukraine. The most perspective approaches and directions of improvement of cargo delivery systems are allocated. A study of the efficiency of the organization of transportation by the criterion of total car-hours of downtime under accumulation. A mathematical model of chemical cargo transportation by carriage, group shipments and transportation of container trains with accumulation to technical norms of trains in the directions of transportation has been developed. The efficiency of two models of chemical cargo shipment organization is compared and a more efficient transportation option is identified. It is established that for more efficient use of rolling stock and reduction of car turnover there is transportation of goods in cars as a part of a container train. The influence of the components of the car turnover on its final value is analyzed. A study of the cost of transportation of benzene in tanks and tank containers in some areas. According to research, the cost of transporting benzene in tank containers on railway ownership platforms is twice less than in private tanks and tanks of Ukrzaliznytsia fleet. These recommendations will improve the process of transportation and increase the volume of goods by rail.

The article provides the concept of intermodal technology, considers ferry types and their advantages and disadvantages; describes the material and technical base of cargo transportation on ferries, design features of ferries, the technology for loading, transporting and unloading of wagons and cars. Reducing the transportation distance and cargo operations time make it possible to increase cargo transportation efficiency on ferries in comparison with transportation of the same cargo with numerous transshipments from one transport type to another. The history of ferry lines development in Russia and abroad emphasizes the importance of type of transportation. In Russia, the history of cargo transportation on ferries is considered to be from the end of the XIX century. There were five ferry lines operating in the former USSR. The article considers such lines as the Kerch line between the Crimea and the Caucasus and the Vanino – Kholmsk line through the Tatar Strait. The development of cargo transportation in the post-Soviet period in the Baltic and Caspian basins is considered in detail. The table shows an analysis of the cargo transshipment volume carried by ferries in the main sea basins of Russia. The history of ferry lines development in Europe began in the middle of the ХIХ century in Scotland and Ireland. The greatest development of ro-ro cargo transportation was achieved in the countries of the Baltic basin. Such transportation is also being developed in Japan, the United States and other countries.
