具优先权下航线收益管理问题的边际分析方法

采用边际分析方法,研究、分析了这样一类航线收益管理问题:两票价等级座位数的最优划分,低等级座位的机票具有优先权。并得出在相应条件下的航运旅客总收入函数,在此基础上,推导出了一个以部分条,牛期望值和逆向累积概率分布作为表达式的最优划分公式,并与传统公式及文献1]所得结果进行了比较分析。证实了新公式的有效性。

A STUDY ON THE MARGINAL ANALYSIS METHOD FOR THE AIRLINE YIELD MANAGEMENT UNDER PRIORITY

The theoretical basis for our research is drawn from how we can correctly determine the optimal seat allotments when the various types of passengers demands are not independent each other.We focus our attention on such a special airline yield management problem in this paper:two-fare-class seat inventory control,the mix of early-book ing,low-fare passengers and late-booking,high-fare passengers.Then a new formula is presented for determing the optimal seat allotment on the basis of the marginal analysis method.The formula deduction is demonstrated in detail.The result of this paper shows that the optimal seat allotment depends on both the inverted cumulative distributions for the two types of passengers and the partial conditional expectations of high-fare passengers.Furthermore,by comparing the formula of this paper with the traditional formula and the result of the reference1],the effectiveness of the formula is verified.
