    Improving the Methods of Estimation of the Unit Train Effectiveness
    (Silesian University of Technology, Poland, 2016) Kozachenko, Dmytro M.; Vernigora, Roman V.; Balanov, Volodymyr O.; Sannytskyy, Nazar М.; Berezovy, Nikolay I.; Bolvanovska, Tetiana V.
    ENG: Summary. The article presents the results of studies of freight transportation by unit trains. The article is aimed at developing the methods of the efficiency evaluation of unit train dispatch on the basis of full-scale experiments. Duration of the car turnover is a random variable when dispatching the single cars and group cars, as well as when dispatching them as a part of a unit train. The existing methodologies for evaluating the efficiency of unit trains’ make-up are based on the use of calculation methodologies and their results can give significant errors. The work presents a methodology that makes it possible to evaluate the efficiency of unit train shipments based on the processing of results of experimental travels using the methods of mathematical statistics. This approach provides probabilistic estimates of the rolling stock use efficiency for different approaches to the organization of car traffic volumes, as well as establishes the effect for each of the participants in the transportation process.
