MODERN DECISION SUPPORT SYSTEMS FOR TRAIN DISPATCHER
The main problems of train dispatcher work are considered. Substantiated is the need to develop the smart decision support systems, containing the means for predicting the situation development in case of delays in train traffic or malfunction of railway system objects. A review is given of several foreign systems, providing such functionality. Discrete event models of railway infrastructure components (stations, stages, etc.), models of trains movement group control are considered and represented in the form of Petri Nets in order to build automatic systems, providing safe trains movement control in real-time mode.
