Abstract：This paper studies the utilization of bottleneck sections and track allocation problems (UBSTAP) for large railway passenger stations under uncertain train arrival/departure at/from stations.First,an integrated model of the UBSTAP for large railway passenger stations under an uncertain scenario is developed.The UBSTAP model considers the occupation times of tracks and their occupation frequencies.In addition,the relationships of train-bottleneck-track are mathematically proposed to represent train routes.After processing the average and variance of train ar-rival and departure times for one month's data from Baoji railway station,the train arrival and departure times are mathematically represented by functions.Meanwhile,considering the NPhardness of the problem,a simulated annealing based heuristic algorithm is developed to solve the UBSTAP model.Finally,a case study of Baoji railway station is carried out to illustrate the effectiveness of the model and the algorithm.
