中文摘要：

提高空中交通管理效率的客观需求促进了自动化空管系统的研发，空管自动化系统主要包括航空器轨迹合成系统和实时排序计划系统两个部分。文中主要讨论实时系统中排序模块的算法及其程序模拟实现问题。该算法主要针对进近空域内进场航空器排序的问题进行处理。在一定假设条件下，大量航空器的进场行为可以抽象成数学模型，而排序过程可以被定义为一个求最优值的函数。最后通过计算机程序验证该模型。

英文摘要：

Promotion of the research and development of automatic ATC system comes from the need to improve the efficiency of ATC. The automatic ATC system mainly includes two parts ： the aircraft track synthesis system and on - time scheduler system. This article mainly discusses the algorithm of scheduling problem in the on - time scheduler system. That algorithm mainly deals with the problem of aircraft scheduling in approach control area. Under certain assumptions, the incoming of aircrafts can be abstracted as mathematics model, and the scheduling process can be defined as an optimal value function. Finally, scheduling programs are used to setup and test the model.
