Choice of cargo delivery option in multimodal connection based on reinforcement learning

The article discusses the issues of choosing a route and an option of cargo flows in multimodal connection in modern conditions. Taking into account active development of artificial intelligence and digital technologies in all types of production activities, it is proposed to use reinforcement learning algorithms to solve the problem. An analysis of the existing algorithms has been carried out, on the basis of which it was found that when choosing a route option for cargo in a multimodal connection, it would be useful to have a qualitative assessment of terminal states. To obtain such an estimate, the Q-learning algorithm was applied in the article, which showed sufficient convergence and efficiency.

APLIKASI ALGORITMA DIJKSTRA UNTUK MENENTUKAN RUTE TERPENDEK DARI KAMPUS A KE B UIN RADEN FATAH

Finding the shortest direction is one of the options that have been considered while traveling. One of the problems that occur for lecturers, staff, and students of UIN Raden Fatah is determining the shortest direction from Campus A to B. The application of graph theory by using Dijkstra's Algorithm becomes a solution for this problem. This algorithm has the advantage to minimize the expense of the costs by finding the shortest route from starting point to the destination. This study is applied research. The study will discuss the determination of the origin and destination end-point, traverse route, the calculation of the weight distance, analyzes the Dijkstra's iteration to determine the shortest route, and conclusion. As the result, the land route becomes the shortest route option from UIN Raden Fatah Campus A to B. The directed graph of the route represents the location as point, the road as the side, and distance as weight. The result shows that the route distance is 6.94 km using Dijkstra's Algorithm.

RESEARCH OF EFFECTIVE TRANSPORT AND LOGISTICS LINKS IN THE ORGANIZATION OF INTERNATIONAL MULTIMODAL TRANSPORT MINERAL FERTILIZERS

Modern agriculture cannot do without the use of mineral and organic fertilizers. Mineral fertilizers are produced by large holdings both in Russia and abroad, and Russian enterprises have subsidiaries distributed throughout the world. The latter factor makes mineral fertilizers one of the most export-oriented branches of the chemical industry in Russia. According to official statistics in 2019 Russian agricultural companies supplied more than 21 million tons of mineral fertilizers to foreign markets, which determines the peculiarities of the country's market. The purpose of the study is to determine the optimal assignment of consumers to suppliers of mineral fertilizers in the organization of multimodal transportation. The article considers the period of the beginning of the reorientation of the production of mineral fertilizers for export. The issue of creating domestic ports specialized in the transshipment of fertilizers has been studied. The volumes of production and consumption of specific countries and regions that are included in export-import operations with each other are analyzed. Routes of transportation of fertilizers with determination of the shortest distances are studied. The optimization of the existing route option for the delivery of nitrogen and potash fertilizers to Brazil is proposed.

The Contribution of Baku-Tbilisi-Kars Railway to International Trade between Turkey and Turkish Republics

This study examines the potential contribution of the Baku-Tbilisi-Kars (BTK) railway, which is planned to be in service in 2017, to the commercial relationship between Turkey and five Turkish republics (Azerbaijan, Kazakhstan, Uzbekistan, Kyrgyzstan and Turkmenistan). First, the general structure of the last five years of foreign trade between Turkey and these states will be revealed. In the second stage, transport routes which are used extensively in the physical transport of goods in the current trade, and the benefits and drawbacks of these routes will be mentioned. In the third stage, the characteristics of the BTK railway will be specified as a new route option. In the last part, the future contribution of the BTK railway to the trade between Turkey and these states will be evaluated.
