Assessment of Cargo Delivery Quality Using Fuzzy Set Apparatus
(SPC Научно-издательская корпорация, ОАЕ, 2018) Kyrychenko, Hanna; Statyvka, Yurii; Strelko, Oleh; Berdnychenko, Yulia; Nesterenko, Halyna I.
ENG: Abstract. The influence of the existing operation conditions for the time of cargo transportation, i.e. ferrous metals to the port station, was investi-gated. It was proposed to carry out the management of cargo delivery on the basis of determining the values of cargo handling duration while implementing the stages of the schedule. It was proposed to carry out assessment of the delivery process, including transportation using the fuzzy set apparatus. To determine the quality of transportation, an ordered categorized scale of values of the duration of cargo's staying in certain conditions at delivery stages was proposed. The assessment of deviations at all the stages of transportation with the use of linguistic definitions of conditions allows quantifying such an indicator as the transportation quality. The characteristics of deviations during transportation are provided in the linguistic form to the dispatching unit for making a decision. The revealed regularities in devia-tions from the standard schedules of trains during delivery of cargos are an objective basis for taking into account them in the mathemati-cal models of the forecast of time of cargo delivery at each of the defined stages of transportation. The data on the forecasted and actual transportations are accumulated in the existing information base, forming data files for assessing the quality of the transportation process, the adequacy of the mathematical model and correcting of the model in case of significant organizational or technical changes.
Formulation of the Mathematical Model for the Planning System in the Carriage of Dangerous Goods by Rail
(IOP Publishing, 2020) Bibik, Svitlana I.; Strelko, Oleh; Nesterenko, Halyna I.; Muzykin, Mykhailo I.; Kuzmenko, Albina
ENG: The paper aims to the topical issue of improving the system in the planning of carriage of dangerous goods by rail subject to ensuring a high level of safety of the transport process and minimal costs for its implementation. Formalization of this process leads to the formation of an optimization task of the two-stage mathematical model. To implement the first stage, a mathematical model in searching the best route based on risk minimization is developed. In order to exclude the unacceptably complex and expensive options for the carriage of dangerous goods from the many possible routes, the authors abided by the condition not to exceed the critical operating costs. The second stage in the process of planning routes for dangerous goods takes into account the hazard identification study in the technological process of car movement with dangerous goods. Considering that the probability of a potential traffic accident is a complex random variable, which is due to a set of elementary previously unknown events, its estimation was made on the basis of the Bayesian approach. Based on the simulation results, the following reliability values are determined at which a transport accident should not emerge.
Ways to Increase Railway Competitiveness
(Державний університет інфраструктури та технологій, Київ, 2022) Nesterenko, Halyna I.; Muzykin, Mykhailo I.; Strelko, Oleh; Shcherbyna, Rozalia; Pavlenko, Olena
ENG: Nowadays, railway transport is the most developed in Ukraine. It is the heart of transport services for individuals and legal entities, without it is difficult to imagine the normal functioning of production facilities and logistics firms. Rail transport also occupies the main place among domestic traffic. Passenger transportation occupies a significant place in the work of transport, so suburban transportation occupies the second place in terms of mass transportation after intercity transportation by automobile transport . The demand for this type of transportation can be called elastic, since there is an impact of seasonality on transportation, for example, the beginning and ending of academic semesters, vacation time. Therefore, it is advisable to consider tourist trains that could run on sections of the Dnіpro-Pіvdennij station – Apostolovo station, Dnіpro-Pіvdennij station – Surskoye station, Dnіpro-Pіvdennij station – Zhovtokamenka station, Dnіpro-Pіvdennij station – Elizarovo station. The article provides graphs of the movement of these trains, allowing passengers to visit attractions along the entire route. Consequently, tourist routes can improve the development of tourism throughout Ukraine, and not popular destinations. This may result in increased demand for tourist trains, increased monetization of passenger transportation, thereby improving passenger comfort.
