AnyLogic-Based Discrete Event Simulation Model of Railway Junction

摘要

Nowadays, increase of competitive ability and effectiveness of railway transportation network of the Russian Federation is an important problem, which solution requires the modernization of system elements such as railway junctions. Modern computer technologies allow assisting in correct project deci-sion-making, however, there is a necessity of development of appropriate software instruments for analysis. In this paper, mathematical model of Ekaterinburg railway junction, developed by means of the instrument of simulation modeling AnyLogic, is presented. The model was constructed using discrete event approach and queuing network technique that give an opportunity to estimate indices of railroad operation and discover bottlenecks in structure of the junction. Calculation of the estimation errors of output parameters was conducted on the basis of the simulation experimental results, which analysis allowed making conclusion about the adequacy of the model.
