【摘要】 考虑席位类型的旅客列车开行方案可以提高各类席位的上座率,增加铁路运输部门的收益,提升旅客对铁路运输服务的满意度。从旅客和铁路部门2个角度出发,以铁路运输收益最大化和未满足理想席位类型的旅客数量以及各类席位虚糜数量最小为优化目标,以客流守恒定律、列车编组、各类席位的上座率和客流需求等为约束条件,建立考虑席位类型的旅客列车开行方案的多目标优化模型。根据模型特点采用遗传算法求解。考虑旅客多样化的选择需求,设计算例验证模型和算法的有效性,得到列车灵活编组的旅客列车开行方案的较优解,为铁路运输部门的运营提供参考。更多还原

【Abstract】 The passenger train operation scheme considering seat class can improve the occupancy rate of all kinds, increase the revenue of railway transportation department, and improve the satisfaction of passengers with railway transportation service. From two perspectives of the passenger and railway sector, taking the maximum of railway transportation profit and the minimum number of passengers who do not meet the ideal seat type as the objective function, and taking the conservation laws of passenger flow, train formation, occupancy rate and passenger flow volume demand as the constraint conditions, the multi-objective optimization model is established, which is then solved by genetic algorithm according to the model’s characteristics. Considering the diversified choice of passengers to different type of seats, an example is designed to verify the effectiveness of the model and algorithm, and the optimal solution of passenger train operation scheme with flexible train formation is obtained, which provides reference for the operation of railway transportation department.更多还原
