Optimization and Simulation of Transfer in Lanzhou Railway Station Square

Based on the background of Lanzhou Railway Station,this paper studies the planning of the station square facilities capacity.Then,the paper establishes a multi-objective nonlinear programming model based on transfer distribution,and solves it by using Lingo software.In addition,the paper analyzes the bottleneck of the square transfer capacity and transfer passengers' flow organization,and presents a better transfer plan.After the improvement,the transfer organization scheme and the streamlines of passengers are simulated by using the Arena Simulation Software.The data of the numbers,walking time,and waiting time are achieved.The results prove the validity of the improvement.The paper considers the passengers' transfer time and distance,and optimizes the proportion of transfer passengers' flows.The transfer scheme is better in three aspects including operation efficiency,layout rationality and satisfaction.
