非调度因素对航空器除冰保障能力的影响分析

Effects of non-scheduled factors on aircraft deicing guarantee ability

为研究非调度因素对繁忙机场冬季航空器除冰保障能力的影响,缓解不完整信息条件下航空器除冰需求激增所引发的安全运行压力,采用多目标0-1整数规划构建除冰航空器分配模型,并以我国某典型冬季繁忙机场3年降雪季的13 681架次除冰航班为样本,比较多种非调度因素不同组合下的20种情境,分析非调度因素对航空器除冰保障能力的影响。研究表明：极端降雪天气下,充足的除冰资源投入比资源使用方式优化更能有效提升保障能力;小雪及无降雪（除霜）天气下,航班时刻编排不合理可能导致与除冰资源投入和利用无关的保障压力;除冰资源投入量及使用限制程度共同影响航空器除冰保障能力。

In order to study the influences of non-scheduled factors on aircraft deicing guarantee ability of busy airports during winter operation,and to ease the operation safety pressure caused by the surging demand of aircraft deicing under the condition of incomplete information,a multi-object optimization allocation model of aircraft deicing was built by using the 0-1 integer programming method. Actual data on13 681 deicing flights of a certain busy airport during winter operation in three snowfall seasons were taken as a sample,the factors influencing aircraft deicing guarantee ability were identified by comparing the 20 different situations combined of different snow conditions and different non-scheduled factors. The results show that enough ice apron input can reduce the deicing delay more effectively than optimization of resource usage in extreme snowfall weather,that unreasonable flight timing may result in a pressure on aircraft deicing guarantee ability which has nothing to do with the quantity and using manner of ice aprons,and that the quantity and using manner of ice aprons jointly affect the improvement of aircraft deicing guarantee ability.
