摘要

目的。乌克兰目前正在改革铁路运输市场,这与执行欧洲联盟对其立法的指示有关。由于这些改革,设想向独立于乌克兰的运输公司开放铁路运输市场。在这种情况下,可以通过独立承运人的列车按严格的时间表通行来解决确保铁路车辆进入到站和发车轨道的问题,并消除与列车和乌克兰铁路车辆调车运动的冲突情况。私人机车的使用领域之一是服务于大量装卸货物的地点。在这种情况下出现的任务之一是改进将专用机车分配给列车调度线程的方法。方法。本文以铁路运营工作组织方法和线性规划方法为基础进行了研究。发现。本文考虑改进机车工作机队规模计算方法的问题。根据对乌克兰联委会与私营运输公司之间可能相互作用的条件的分析,确定在执行服务阶段使用私营运输公司的可能选择之一将是在大量装卸货物的地点提供服务。在研究过程中,提出了一种将该问题简化为目标优化问题来确定机车数量的方法。本文给出了一个实例,说明了如何确定运输谷物货物所需的机车队,并制定机车周转率计划。为运输服务所需的机车数量被确定,机车与火车连接的程序也被开发出来。创意。在线性规划方法的基础上,改进了机车调度方法。实用价值。这项工作的结果使我们能够评估独立承运人在铁路运输公开市场上对机车车队的需求。

DEVELOPMENT OF A METHOD FOR ASSIGNING PRIVATE LOCOMOTIVES TO TRAINS
Purpose. Ukraine is currently in the process of reforming the railway transportations market, which is related to the implementation of European Union Directives to its legislation. As a result of these reforms, the opening of the railway transportation market for carriers independent of Ukrzaliznytsia is envisaged. In such conditions, the problem of ensuring access of rolling stock to the receiving and departure tracks and the elimination of conflict situations with train and shunting movements of rolling stock of Ukrzaliznytsia can be solved by passing trains of independent carriers according to a tight schedule. One of the use areas of private locomotives is servicing of points of mass loading or unloading of goods. One of the tasks that arises in this case is to improve the methods of assigning private locomotives to the threads of the train schedule. Methodology. The research is performed based on the methods of organization of operational work of railways and methods of linear programming. Findings. The paper considers the problem of improving the methods of calculating the size of the working fleet of locomotives. Based on the analysis of possible conditions of interaction between Ukrzaliznytsia JSC and private carriers, it is determined that one of the possible options for using private transport companies at the stage of implementation of their services will be the service of points of mass loading or unloading of goods. In the course of the research a method of determining the number of locomotives by reducing this problem to an optimization problem of purpose was developed. An example of solving the problem of determining the required working fleet of locomotives to service the transportation of grain cargo sent to the port by shipping routes and developing schedules of their turnover is given. The number of locomotives needed to service transportations was set and the procedure for their connection to trains developed. Originality. The research improves the methods of assignment locomotives to the threads of the train schedule based on the use of linear programming methods. Practical value. The results of the work allow us to assess the needs of the working fleet of locomotives in the open market of railway transportations for independent carriers.
