大型航空运输企业航班恢复系统(RM)应用研究

随着航空公司机队规模和运营航线的不断扩大,在发生大面积航班延误时,航空公司需要快速计算出最优的航班恢复方案。为了提高运行控制效率,探索一种优化控制的方法,根据经济效益、航班正常等不同的目标要求,计算出最优的运行方案,最终达到快速、高效地调配航班。分析了大型航空运输企业不正常航班恢复的主要场景,在此基础上筛选了制约航班恢复的关键约束条件,设计了航班恢复和校验的基本逻辑,通过应对台风处置的实际案例,验证了某大型航司和美国世博公司的航班恢复系统(RM)在实际案例应用中的效果,总结了该航班恢复系统的优点和存在的风险及短板。实践表明,该系统可缩短2 h航班运行恢复时间,平均每个受影响航班减少延误30 min,减少相应的成本2万元,提升整体航班正常率3%~5%。

Application of flight recovery system in large aviation transportation enterprise

With the continuous expansion of the airline fleet size and operating routes,airlines need to work out quickly the optimal flight recovery plan during massive delay cases.In order to improve the efficiency of operation control,an automatic flights adjustment method was explored.According to different objectives such as economic benefits and flights on-time performance,the optimal operation scheme can be worked out,and eventually the rapid and efficient deployment of flights was achieved.This paper analyses the main scenarios of flight recovery,establishes the key restriction,designs the basic logic of recovery and verification,along with the application of a large aviation transportation enterprise,cooperated with Sabre Solution company.The advantages,risks and shortcomings of the flight recovery system are summarized.The practice shows the recovery manager system(RM)can reduce recovery time by 2 hours,reduce average delay time of each delay flight by 30 minutes,cut down the corresponding cost by 20,000 yuan,and improve airline’s total flight on-time performance by 3%~5%.
