摘 要: 以乘客的总广义出行费用最小、地铁部门运营成本最小为目标,以列车满载率、列车编组长度、列车开行频率为约束条件建立地铁列车开行方案设计多目标规划模型并求解。通过设置权重的方式,将地铁列车开行方案制定中追求的乘客总广义出行费用最小与地铁运营公司运营成本最小双目标转化为单目标。并给予了3 组不同的权重设置方案,分别求得相应的最优解,分析了权重设置对最优解的影响。所提供的权重设置方法,可以准确描述决策者在地铁列车开行方案制定过程中的决策偏好,能够为地铁列车开行方案的制定提供决策支持,有较大的实用价值。

Abstract:Taking the minimal summary generalized cost of passengers and the minimal operating cost of the subway company as the objectives and train full-load ratio,train length and operation frequency as the constraints,a multi-objective programming model was built and solved.The multi objectives are united into a single objective by setting the weights.Three schemes were proposed,when their the problem solved accordingly and the effect of the weights on the solutions were analyzed.The weights can exactly describe the decision preference in line planning for subway and this approach can support the line planning,which is very valuable.

 

Key words: subway train; line plan; multi-objective programming; weight; decision preference
