Formation of the freight trains with a fixed train schedule

The hypothesis of the study consists of the detailed consideration of the process of accumulation of wagons, taking into account the arrival of individual groups of wagons, determination of options for freight trains with a fixed train schedule and substantiation of analytical dependencies that determine the cost of wagon-hours for accumulating trains and obtaining new scientific results on this basis. Their practical use will make it possible to more accurately and reasonably normalize the idle time of cars under accumulation, as well as to clarify the methodology for calculating the train formation plan. The research methodology is based on existing methods and methods of forming freight trains for a rational way of implementing the train schedule. Results of the study: the methods of standardizing the idle time of cars under accumulation were stated, the regulations of idleness of cars at the sorting yard were clarified, and options for optimizing the plan for the formation of trains were proposed

LINKING TRAIN SCHEDULE ASSIGNMENTS TO A SOLID SCHEDULE

The article provides an analysis of the composition of the sorting station during the accumulation of trains and the formation of trains with their departure on a solid schedule in order to establish dependencies that allow you to determine the cost of wagon-hours for the accumulation of cars and the rationale for the use of a solid schedule. The paper highlights the features of the process of accumulation of cars with a solid schedule as opposed to accumulation with a flexible schedule. As a result of modeling the composition of the solid schedule, the necessary parameters were calculated, which were compared with each other to confirm the correctness of the proposed methodology

Optimization of transport flows of the grain storage

Ensuring uniform supply of wagons for loading and unloading of goods is one of the main tasks of the transport process. Existing methods for solving the issues of ensuring the rhythmicity of the supply of wagons for loading grain are not often allowed to identify the causes of the technological shortage of wagons. In this regard, within the framework of this work, the aim of the study is to increase the efficiency of the organization of providing grain storage with wagons using models
