Time Parameters Optimization of the Export Grain Traffic in the Port Railway Transport Technology System

Mathematical Modeling of Cargo Flow Distribution in a Regional Multimodal Transportation System

“…A large number of studies carried out in recent years are related to the optimization of the distribution of cargo flows, including those considered within the framework of multimodal transportation systems [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. This takes into account the drastic transformations that have taken place in the transport industry and associated with the development of the transport services market, as well as focused on a more complete fulfillment of the conditions put forward by customers.…”

“…The economic-geographical method was developed by the authors in [13] as a general approach in transport and logistics research. In this paper, this method is developed in combination with the numerical method developed by the authors in [14] for optimizing freight transportation with the considered time parameters. At the same time, the general theoretical basis for transport and logistics constructions is the egalitarian approach in the welfare theory [15].…”

Mathematical methods in studying the territorial oligopolistic market of freight transportation

“…The issues of studying the efficiency of multimodal cargo transportation, including transshipment in seaports, have been the subject of many recent studies (see, for example, [1][2][3][4][5][6][7][8][9][10]). The globalization of transport processes, accompanied by pervasive digitalization, as well as differences in the goals and objectives of the participants in these processes, lead to the need for a deeper and more comprehensive study of them.…”

“…The resulting territorial picture of the delimitation of cargo flows in the region makes it possible to formulate recommendations when choosing rational distributions of these flows to the unloading stations. In [7], an approach is presented in the study of distributions of freight traffic based on two-criteria optimization with time parameters, in which the peculiarities of the warehouse and transport infrastructure of the region under consideration are taken into account in sufficient detail.…”

“…The first method [6], based on the principles of analytical geometry, allows you to build an economic-geographic model of the oligopolistic territorial transportation market for the considered transport loop. The application of the second method [7] consists in solving a multicriteria transport problem posed for the considered transport and technological system in the form of an integer programming problem. In both cases, the practical implementation of the developed algorithms is carried out in the environment of the system of analytical calculations.…”
