备份飞机在保障航班正点率上的作用研 究简

本文应用GPSS仿真软件，对备份飞机在保障航班正点率的作用进行仿真分析，结合备份飞机策略的经济性，综合评价备份飞机在解决航班延误上的作用。最后通过京沪航线的实例证明在运营机场备份一架飞机不仅可以降低航班延误率，而且可以节约航空公司的成本，并通过测算确定出了备份飞机最优数目。

Research on the Role of Spare Aircraft in Flight Punctuality Rate

By using the GPSS simulation software, this paper simulates the effect for flight punctuality rate. Combining with the economy of spare aircraft strategy, it co ates the role of the spare aircraft in the airline schedule disturbances problem. Taking of the spare aircraft mprehensive evalu- Beijing - Shanghai route for example,it proves that using a spare aircraft not only can decrease the delay rate, but also can save the cost of the airlines. Meanwhile, the paper determines the optimal number of the spare aircrafts in this example.
