Abstract

An efficient control of processes in marshalling yards is an important part of railway cargo services. A model of a marshalling yard can be used as a support for a design of a yard, it can serve for planning tasks and can become a basis of an information system or a decision support system for a dispatcher. The article describes the model of a marshalling yard which is based on a general model of a transportation system but respects the special features of a railroad transport. The modelled processes include finding a path in a yard, dynamics of a motion of wagons in yard and problems of a simultaneous sorting. The article concentrates on technological processes in a yard which create only apart of a complete simulation model of a marshalling yard. 1 Introduction Transportation systems can be
