Abstract:

Based on revenue management, the dynamic slot control model for railway freight trains is established based on discrete time, considering customer demand transfer and multiple slot bookings behavior. And we point out that there is at least one (if it exits) reservation request accept/reject threshold points at each decision stage. In the meantime, we constructe the two sets of interval sequences using the threshold points of each types slot, and then we establish the reservation request accept/reject policy for each set of interval sequences. In addition, we also prove that the properties of expected revenue function and the monotonicity of the threshold points with respect to demand transfer rate. Finally, the feasibility of the optimal slot control strategy and the correctness of the relevant properties are verified by three sets of simulation experiments.

Key words: railway transportation, slot allocation, revenue management, demand diversion, multiple slot bookings

摘要:

基于收益管理的思想,综合考虑顾客需求转移和批量订舱行为,建立离散时间的铁路货运班列动态舱位控制模型,指出在任意决策阶段,舱位预定请求接受/拒绝阈值点若存在则至少存在一个的特性.然后在任意决策阶段,利用每种舱位的阈值点构造了两组区间序列,针对每组区间序列给出相应的舱位预定请求的接受/拒绝策略.此外还证明了期望收益函数的性质及阈值点关于需求转移率的单调性.最后,通过设计3 组仿真实验分别验证了最优舱位控制策略的可行性及相关性质的正确性.
