收益管理研究

目前实现了emsr-a、emsr-b和已经修正的emsr-b算法

The emsr-a, emsr-b and the modified emsr-b is up to date

*实际操作中,航班的预定限额在线下定期计算,并传输给预约系统用于对预定的分配

预定限额的定期重算与预约系统内的嵌套预定限额结合构成了一个动态的预定系统

动态预定控制流程

  1. 计算航班的初始预定限额
  2. 当收到一个等级j的预定请求时,把请求的座位数量与那个等级当前的预定限额进行比较
  3. 如果请求的座位数量超过了等级j的预定限额,则拒绝请求,转到步骤6
  4. 如果请求的座位数量在等级j的预定限额范围内,则接受请求。取决于系统的预约能力:
    • 要么从可获座位数量为正数的各等级预定限额上减去接受的座位数量
    • 要么从所有等级的预定限额上减去接受的座位数量
  5. 当一个预定被取消时:
    • 要么从可获座位数量为正数的各等级预定限额上加上的退订座位数量
    • 要么从所有等级的预定限额上加上接受的座位数量
  6. 基于预定总量及每个等级的期望需求,定期重算所有的预定限额,直到起飞为止(重新优化)

收益管理的评价标准

收益机会度量(ROM) 航班实际取得的收益与没有收益管理时的收益差值占总收益机会的百分比
