摘　　要：考虑客流本身的波动、客流预测的误差以及沿途车站的票额实际利用等问题,提出一种给定客流条件下的旅客列车票额预分算法。根据实际工作的特点和需求,总结旅客列车票额智能预分原则,并提出基本流程。将票额预分过程划分为基于给定客流的基本票额分配优化及剩余能力优化利用两个主要步骤。针对基本票额预分优化,以客运周转量和平均运距最大化为目标构建了双目标优化模型,并基于e-constraint方法提出了求解算法。针对剩余能力优化,以平均运距最大化为目标,并考虑车站的保护票额构建了优化模型,提出了相应算法。案例计算结果表明,该模型具有较好的实用性。Intelligent passenger ticket pre-assignment models and algorithms under given passenger flow conditions were proposed considering several problems in practical work including the fluctuation of passenger flow,the deviation of passenger forecasting and the actual utilization of passenger tickets at stations along the route.According to the characteristics and demands of practical work,the principle of intelligent ticket pre-assignment was presented and the basic process with two main steps including basic pre-assignment based on given passenger flow and optimization of remaining train capacity was also proposed.The model with two objects including maximizing passenger turnover and average travel distance was constructed for the first step and an algorithm based on e-constraint method was proposed.The other model for the second step to maximize passengers'average travel distance was also constructed.The interests of passing stations were also considered in the second model.The case application shows better practicability of the models and algorithms.Key Words:ticket assignment
