Abstract: Aiming at the low efficiency of taxi operation and management in railway passenger transport hub, the optimization model of the number of taxi operation lane was studied. Firstly, the problem of taxi operation organization in railway passenger transport hub was analyzed, and was abstracted into M/M/C queuing system to obtain the steady state index of the system. Then, the number of service desks in system was taken as a decision variable, the traffic mode choice model of railway passenger transport hub was taken as a constraint, and the optimization model of the number of taxi operation lane in railway passenger transport hub was established, with the goal of minimizing the sum of system operating costs and waiting costs of passengers. Finally, an example was given. The research results show that: the scheme obtained by the proposed model can make the comprehensive cost minimum and the service level higher than the actual situation; the feasibility of the proposed model is verified, which has important theoretical value for improving the operation efficiency of railway passenger transport hub and the service quality of taxi system.

摘要： 针对铁路客运枢纽出租车运营管理效率较低的问题，对出租车运营通道数优化模型进行研究。首先对铁路客运枢纽的出租车运营组织问题进行分析，将其抽象成M/M/C排队系统得到系统的稳态指标；然后以系统服务台数为决策变量，以铁路客运枢纽交通方式选择模型作为约束，以系统运营成本和乘客等待成本之和最小为目标，建立铁路客运枢纽的出租车运营通道数优化模型；最后给出了具体算例。研究结果表明：模型得到的方案能够使综合成本最小且服务水平高于实际情况，模型具有可行性，对提升铁路客运枢纽的运营效率和出租车系统的服务质量具有重要的理论价值。
