中文摘要
      研究运营企业效益最大化和社会总成本最小化2个不同目标条件下城际铁路开行频率的优化,建立双层规划模型,上层分别以铁路企业效益最大化和社会总成本最小化为目标,下层以开行方案作为变量、以用户均衡理论建立模型,利用模拟退火算法得出城际运输通道中不同交通方式的分担率,并求出不同等级城际列车的客流量及开行频率.通过算例进行验证,对比和分析了2种目标下的城际列车开行频率方案,为城际通道客运优化管理提供理论参考.
英文摘要
      A bi-level programming model was established, of which the upper level pursues the maximum railway enterprise’s benefits and the minimum social cost respectively, and the lower level was modeled based on users equilibrium theory, to figure out sharing rate of different transport modes, passenger flow of different ranks intercity trains and operating frequency of trains with different dwell plans and objectives. The bi level model was solved by simulated annealing (SA) algorithm. In the end, this paper contrasted and analyzed the operating frequency of intercity trains under the two different objectives respectively by a sample to provide theoretic support for optimal management of railway in intercity passenger corridor.
