Intelligent transport systems development

In the classical formulation, the well-known problem of the distribution of empty wagons is considered as a transport problem of linear or dynamic programming with cost optimization at a minimum of wagon-kilometers. If the «just in time» condition is met, it is necessary to take into account the additional condition of dynamics in terms of the time of receipt and the time of «consumption» (feeding for loading) of empty wagons. Developers of intelligent systems should take this into account.

In market conditions, guaranteed delivery of goods is one of the main tasks of JSC «Russian Railways». This is the most important indicator of the quality of the company’s products, its competitiveness.

It is required to develop an intelligent system with the objective function of minimizing fines paid by JSC «Russian Railways» due to late delivery of goods. The methodology for solving this problem within the framework of the RTCC should be based on the ranking of wagons arriving at the railway (in the region) with varying degrees of delay in relation to the delivery dates, determining regulatory measures to accelerate the promotion of such wagons, taking into account the degree of their delay, developing proactive measures for wagons with possible violations of the delivery time of goods.

Some of the stated provisions have already found practical implementation.

The Oktyabrskaya railway experience

On the Oktyabrskaya mainline, a specialized dispatch center for a high-speed traffic polygon (SRTCC) has been created, in which the general principles and basic provisions of the integrated intelligent transportation process management system are implemented. Particular importance is attached to ensuring traffic safety.

The approved technical means, including innovative solutions for monitoring the position of mobile objects (trains) based on the GLONASS system, were used in the creation of the SRTCC. As an information base, the systems of AWS train dispatcher, AWS of the energy dispatcher, automated system for analysis of planning and execution of intermissions, Warning systems – v.2 and automated rolling stock control system, monitoring the condition of rolling stock), сomplex automated system of accounting, control of elimination of failures of technical means and analysis of their reliability, «GID -URAL» (traffic schedule) are used) and others. Information exchange is organized with specialized infrastructure systems – paths, automation and telemechanics, etc.

The system-wide part of the hardware package is implemented within the Oracle Windows Cluster Server DBMS. At the same time, regional – level application complexes are implemented within the framework of the high-speed traffic control center, and the network level – in the form of operational reporting forms. The main decisions are formed by the central management complex of SRTCC «Intellect».
