Technology improvement of organization and control of wagon flows at technical stations

Object of work. as received the “Chuqursoy” sorting station at the disposal of the Uzbek Railways AJ.
From Figure 1 it can be seen that the parks of the sorting station “Chuqursoy” are located in series. Such a location is considered very important in the processing of the flow of wagons. But it is known that even in any schematic layout, one of the elements that determines the intensity of work of the station is the sorting Hill. Hence, this is the main “weak spot”of the station in processing the flow of wagons (Figure 1).
At the station” Chuqursoy", it was analyzed how much time the Wagons spend on each sorting element, and the result was given in Figure 2.

Figure 2. The average time consumption in each sorting element of the recyclable wagons is the connection
How this element is equipped despite the minimum time spent on the sorting Hill (Figure 2) plays an important role in increasing the station's processing capability.
Shipping Park 31%, sorting Park 52%, sorting Hill 4%, receiving Park 13%.
The main task of the technical stations is to process the wagon flows and structure the trains in optimal mode, based on the minimum and technological basis of the way the wagons stand at the station. Therefore, the main performance indicator of the technical stations is the “Standing time of the wagons”. The performance of this indicator is currently considered separate for transit recyclable and non-operational and for local cars.
Inefficient time losses in the process of performing various actions with wagons in the organization and management of wagon flows at technical stations under JSC “O‘TY” are increasing from the established technical criteria. In particular, according to statistics, it can be observed that at the Pitursoy station, which is considered the largest station by volume of work, the average time of staying cars increases by 1-5 hours.
To eliminate such inefficient time losses, it is necessary to increase the efficiency of station work technology for the organization and management of Wagon flows. Therefore, in my scientific work, I aimed to increase the process of processing wagons at this technical station by imitative modeling. In this case, automatic control of the processes until the reception and shipment of wagons to the station is established. This is achieved due to the digitization of the work of the central documents and receiving and sending parks and sorting Hill, which are currently being carried out at the station. This results in a 15-20% reduction in wagon standing times on average. Economic efficiency, on the other hand, is a result of reducing the average stay-time costs of Wagon, shunting and train locomotives.
As an example, the average stay rate of 1 wagon is 16,500 at present. An average of 1,100 wagons are processed per day at Chuqursoy station. So, if we reduce the time of wagon stay at the Chuqursoy station by 1 hour, then the expected economic efficiency is 18 million 150 thousand, and Per Year-6 billion. 624 million is 750 thousand. In addition, there is an opportunity to achieve economic efficiency both from locomotive fuel costs and from the monthly fund of workers due to the digitization of the work process.

During the academic year 2022-2023, a total of 21 articles were published on the results of scientific and methodological works, including 1 teaching manual in the co-Organization, 5 in foreign (recognized by the Higher Attestation Commission) and 8 in domestic prestigious (high-factor, recognized by the Higher Attestation Commission) journals and 2 in foreign scientific conferences. Moreover, his scientific activity is associated not only with his specialty, but also with the processes of the field of ijtimoy and Natural Sciences. He has published scientific (creative) articles in 5 journals in the field of Natural Sciences and conference materials

Also, a program for electronic computing machines (DGU) was created. In this work, the basis for calculating the speed indicators of movement of railway sections and lines is mainly the length of railway sections and lines, the running times of freight trains on plots, the norms of time spent on technological actions performed by freight trains at technical stations, the interval between trains, the times when the flow of freight trains is spent on acceleration and deceleration.
