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。
