本文描述了一种基于几何规划的空中交通管制中基于优化的冲突解决新方法。与大多数纯粹关注飞机间隔问题的方法相比，这种方法的一个关键特征是它还能够考虑交通流管理级别发布的各种计量指令。此外，所提出的方法可以解释冲突解决问题的公式中存在的一些非线性，同时相对于最快的基于线性编程的方法，仅在计算时间上产生很小的损失。可以引入整数变量来提高解决方案的质量并包括组合选择，例如优化合并流中的飞机序列。仿真结果证明了该方法在解决各种飞机间隔问题上的效率，包括通过空域修复和边界来限制飞行里程和飞行分钟数。
This paper describes a novel optimization-based approach to conflict resolution in air traffic control, based on geometric programming. A key feature of this approach is its ability to also take into account various metering directives issued by the traffic flow management level, in contrast to most methods that focus purely on aircraft separation issues. Moreover, the proposed methodology can account for some of the nonlinearities present in the formulationsofconflictresolutionproblems,whileincurringonlyasmallpenaltyincomputationtimewithrespectto the fastest linear-programming-based approaches. Integer variables can be introduced to improve the quality of the solutions and to include combinatorial choices, for example, to optimize over aircraft sequences in merging streams. Simulation results demonstrate the efficiency of the approach on various aircraft separation problems, including miles-in-trail and minutes-in-trail restrictions through airspace fixes and boundaries.
