Item Adaptive Management of Transport Logistics in Agricultural Enterprises(Academic Research Publishing Group (ARPG), 2022) Deineha, Oleksandr; Chymosh, Kateryna; Kobylynska, Tetiana; Nazarov, Oleksii A.; Liapa, Mykola; Sapotnitska, NataliiaENG: Agriculture is a complex logistics system with some features and limitations. The logistics system usually operates in conditions of pronounced uncertainty, characteristic random processes, so the aim of the article is to study and develop recommendations for improving the adaptability of transport logistics management in agricultural enterprises. In the article, the authors considered the specifics of logistics processes occurring in agriculture. The importance of cooperation in the development of logistics of the agro-industrial complex formed based on intersectoral cooperation of public transport enterprises, institutions, service and infrastructure organizations, which have separate transport units, united by technological and economic ties, and use a variety of resources of the region for the formation and implementation of transport services. The financial content of cluster development as a tool of competitiveness and innovative activity of agricultural enterprises is reflected, which allows realizing the available potential to increase sales.Item Assessment of the Urban Freight Regulations Impact on the Transportation Cost(4S go, s.r.o., Slovak Republic, EU, 2022) Galkin, Andrii; Nazarov, Oleksii A.; Shapoval, Ganna; Kolosok, Valeriia; Khodova, Yana; Kuznetsov, AnatoliiENG: The paper will investigate the impact of the vehicle carrying capacity to which the local tax is applied on forming the cost of delivery. The cost of 1 ton of freight under different tax scenarios is estimated in the paper: without tax 0, with fixed tax – 10% and with progressive tax from 0 to 75%. The greatest effect on reducing the vehicle's load capacity during urban deliveries showed a progressive tax. The developed regression model allows determining the cost of transportation of 1 ton of goods depending on the technological parameters of transport operations, the costs of the transport (logistics) operators to perform these operations, and local tax regulations for transport. The application of the model makes it possible to regulate the use of vehicles of a given capacity by the local administration. In contrast to the strict prohibition on the establishment of traffic signs, the use of a progressive tax by the local administration makes it possible to regulate traffic structure by economic methods. Exploring of influence local tax regulations on transportation will lead to the sustainability of the cities in order to provide GREEN technologies.Item Mathematical Modelling of the Communication Channel between the Rail Circuit and the Inputs Devices of Automatic Locomotive Signalization(Dnipro National University of Railway Transport named after Academician V. Lazaryan, 2019) Hololobova, Oksana O.; Buriak, Serhii Yu.; Havryliuk, Volodymyr I.; Skovron, Ihor Ya.; Nazarov, Oleksii A.ENG: Abstract. In modern practice of operating under traffic safety conditions, the traffic light signal must be transmitted to the locomotive that moves to it, and duplicate in the driver's cab. However, this communication channel is not protected from external interference. In order to prevent the occurrence of code failure, it is necessary to create conditions under which the automatic locomotive signalling system will distinguish between signals with useful information, from signals with false information. The best way to solve this problem at the first stage is to model the devices. Using the simulation tools of graphical environment of simulation modelling Simulink from Matlab software environment, the software model of the communication channel between the railroad and the input devices of automatic locomotive signalling system was constructed. The created mathematical model with the actual parameters allows us to obtain diagnostic signs of a proper condition, on the basis of which the research is aimed at the identification, recognition and definition of various types of malfunctions, failure, damages and defects in the work of the constituent elements of the system and the signal transmission channel of the automatic locomotive signalling system.
