Railway Network Blocking Problem: An Optimization Modeling Formulation about Flow Routing Problem

In this paper, we mainly study on modeling formulation for railway network blocking problem. We propose model formulation for RBP. The objective function of RBP model is to minimize the costs of flow traveling and delay for the train in marshalling station, by deciding which block is built and specifying the assignment of commodities to these blocks, while observing limits on the reclassification capacity at each terminal. The model is solved using GAMS. The model is tested on a real-world railway network located in North of China, the computation results show that the model have the potential to apply and can yield the dramatic railroad's operating costs saving.
