| Abstract: | This paper analyses the generating reason and operation characteristic of angular car flows, discusses the main factors that influence the number of angular car flows at bidirectional marshalling station. Based on profoundly analysis of exchange ways of angular car flows, the comprehensive optimization model which is subject to capacities of all subsystems at bidirectional marshalling station is constructed. The model is solved by using Genetic Algorithm, and a simulation example is calculated by using the model and algorithm built in this paper. |
