    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.

    Use of Cargo Delivery Process Model for the Assessment of Logistics Service Quality
    (SPC Научно-издательская корпорация, ОАЕ, 2018) Kyrychenko, Hanna; Nesterenko, Halyna I.; Avramenko, Svetlana I.; Lytvynenko, Serhii L.; Yanovskiy, Peter A.; Lytvynenko, Larysa
    ENG: The paper proposes the method of forecasting the time of operations with a wagon and a cargo, which is carried out using the cargo deivery process model taking into account possible scenarios of the process and deviation from the forecast and technological standards. One of the concepts of the model is the average deviation from the forecast. This method for the first time allowed considering the condi-tions of real operational work when forecasting control points of cargo delivery process stages. Data on deviation is proposed to be stored in the database of the automated system for forecasting. The paper also proposes an estimation of deviations at all stages of transportation using linguistic definitions of the states, which allows quantifying the indicator, such as the quality of transportation. The given method allows forecasting the time control points of the scheduled cargo delivery stages considering the conditions of real operational work. One of the prospects for using the above method is the ability of information interaction of the transportation participants, namely, in the part of exchange and processing of operation monitoring data, data on deviations from the forecast and standards, as well as the exchange of delivery quality assessment data.
