The use of simulation experimental research in different areas concerning railway traffic control issues

Abstract

The article presents examples of transport applications in which simulation experimental research is of great importance and particularly useful. The first part presents examples of important railway transport areas where computer simulations have been used. In the second part of the study, more reference is made to the study of the exploitation process of railway traffic control devices using a so-called simulation experiment. As railway control systems are complex systems, it is practically impossible to carry out direct studies or carry out diagnostics without disconnecting a component from the complete system. This is when simulation research becomes helpful. In the simulation of the exploitation process, the initially known theoretical cumulative distribution functions of times between failures and times of repair of the objects distinguished in the model of the railway control system and the distributions of the number of their failures were assumed. The exploitation and reliability parameters of these objects were then determined based on real data, using statistical analysis and on the basis of simulations of future exploitation states of this system. A parametric and non-parametric verification of empirical distributions of reliability parameters determined for selected system components was also carried out.
