Optimization Research for Utilization of Waiting Hall in Railroad Large-Scale Passenger Station

The passenger railway station is the place for passenger mustering and evacuation. To optimize the usage of waiting halls has great significance for improving railway passenger station operation efficiency. By analyzing the distribution function of the above regularities, methods of calculating the efficient time of passengers occupying waiting halls can be achieved, so is the minimum departure time interval for trains in the same waiting area. On the basis of optimization and analysis of large scale passenger railway stations, Dijkstra algorithm for passenger stream lines of different platforms can be obtained and 0-1 planning model of the minimum waiting areas divided can be established. Based on the above work, constrains on whether there exist parallel operations for railway staffs are established. And phrases are divided into several time blocks plans. The object function is the balance usage of waiting halls in large scale railway stations in one day and the shortest passenger stream lines in waiting halls. Dynamic planning model for the usage of waiting halls of large scale passenger railway stations is proposed. Optimal algorithm is also present. Finally, the model can be confirmed based on Lanzhou railway station. Optimal results show that the optimal model for usage of waiting halls in large scale passenger railway stations can reach the usage balance of waiting halls and the shortest passenger stream lines.
