MODELING OF UNPRODUCTIVE LOSSES IN THE OPERATION OF A SORTING STATION

Abstract

To develop the most universal model for controlling the duration of the elements of the time spent by wagons at the sorting station. The methods of system analysis are used, comparing the performance of the sorting station, mathematical modeling. The concept of explicit and latent losses is introduced when processing wagons at the sorting station. The analysis of the existing standardization method for the time spent by the wagons and its disadvantage is carried out. A method of mathematical modeling of losses in the process of processing wagons at the sorting station was developed. The developed model makes it possible to evaluate the fulfillment of each element of the time that the wagons are at the sorting station and form statistical patterns of their non-fulfillment, and also makes it possible to develop action plans to reduce losses in the processing of wagon flows.
