Application of computer technology is one of the ways to improve the operational management of railway transport at powerful coal mines with a large number of mining equipment and a developed network of railway tracks. Preliminary determination of the effectiveness of new methods of management is best to produce modeling the work of the mines. At the same time, an idea of the effectiveness of new methods and systems of operational management is given by comparing the results of modeling and the results of actual operation of the mine. In this paper we consider the essence of modeling by the method of actual shifts, its positive and negative properties and the scope of application ...
