Удосконалення технології організації групових поїздів оперативного призначення на основі синхронізації графіку руху на станціях обміну груп вагонів

Abstract

The work is dedicated to the problem of automation of specialized schedule of group train chains traffic with successive replacement of car groups at several technical stations simultaneously according to the direction of car flow movement.A mathematical model for group trains traffic schedules synchronization at car groups exchange stations on the basis of the determined reasonable variant of integration of car flows according to the plan of making-up of trains has been developed. The given mathematical model is presented in the form of an objective function which minimizes overall time of car group detention at the exchange stations and restrictions which take into account the observance of the technology of group train handling at group exchange stations, inter-train intervals and the duration of train movement on network divisions. The solution of a mathematical optimization model was proposed to be done on the basis of genetic algorithm application. In the perspective an automated system of the coordination of traffic schedule for a great amount of group trains at an enormous network ground can be created on the basis of the obtained mathematical model. Such an approach will allow increasing the level of transport management, accelerating the terms of freight delivery and increasing the competitiveness of railways on the market of transport services.
