THE USE OF SIMULATIONS MODELS IN OPERATIONAL PLANNING OF TRAIN''S OPERATION
The operational planning of train and freight operation is performed using integrated technologies, determining the interaction of all levels of control of operational work using common databases and uniform problem solving procedure. The study with the use of functional model has allowed making a basic conclusion: modern integrated technology of shift-day planning of train formation and train operation demands automation of intelligent forecasting functions. Intelligent forecasting function has to be performed by process control units built based on mathematical models of operation of marshalling yards and models of train movement across road polygon. In addition, a model is required to develop the process of interaction of individual models in the design of the operational plan of the whole road. The principles of construction of these models on the basis of simulation approach are described in the paper.
