基于线性嵌套的舱位控制研究

Seat Inventory Control under Linear Nesting

航空公司的舱位控制作为收益管理的核心,已经受到了越来越多的关注。分析了是否考虑舱位嵌套对高等级舱位的座位保护水平的影响,建立了两种情况下的数学模型,利用拉格朗日乘子法求得高等级舱位座位保护水平的最优解。结果证明,在舱位嵌套下,高等级座位保护水平显著降低。将模型运用到实例中,数据显示该模型可以给出更优的各等级舱位保护水平,提高航空公司收益,避免舱位虚耗。

Airline seat inventory control is the core of revenue management. It has received more and more attentions. The difference whether nesting seat was taken into consideration was analyzed. And two mathematical models were constructed respectively. The optimal solution of high- glass seat protection level was obtained by Lagrange multiplier method. The result of a case proves that nesting seat allocation can achieve a significant lower protection level under seat nesting. The optimal solutions of each glass seat protection level could be given in the model. At the same time higher yield could be achieved by avoiding seat wasting.
