More and more researches have shown that most of the intense geomagnetic storms are caused by fast coronal mass ejections in interplanetary space ( icmes ) . though the ace satellite can provide solar wind data in almost real time for prediction of geomagnetic storms , the time interval is too short ( shorter than 30 - min ) for effective predictions of major geomagnetic storms 位于拉格朗日点的ace卫星可以提供近实时的太阳风数据,但依据ace卫星太阳风数据进行地磁暴预报,时间的提前量非常有限,对于大地磁暴,这个时间提前量往往不超过30分钟,这样的时间提前量对于实际应用来说,是不能令人满意的。
The mo - dified first - come - first - served algorithm , time - adva nc e algorithm and constrained position - shift algorithm are put forward to automat ically plan the most efficient landing order , to assign optimal spaced landing times to all arrivals without violate the spacing requirements for different typ es of aircraft and to enhance the usage of the runway under heavy traffic condit ion in the terminal area 为了能够在终端区交通繁忙的情况下高效地为到达的飞机流安排合理的着陆次序,并在不违反飞机间距要求的情况下给出各飞机经过优化的着陆时间,提高机场跑道的利用率,提出了经过改进的先来先服务、带有时间提前量、带有约束的位置偏移三种排序算法。
