机场终端区空域的多条进离场程序优化

Multiple departure and arrival procedures optimization in airport terminal airspace

为有效在战略层面提升机场终端区空域的容量,结合机场布局和环境提出多条进场程序和离场程序的优化设计方法。对进离场程序进行三维建模,每条程序由一条水平面内光滑曲线和一个竖直平面内的近似扇形区域共同构成;提出适应于该模型的冲突检测方法,开发基于改进的分支定界法的多条进离场程序优化算法。通过仿真测实验证了算法能够有效生成满足避障、航路间隔等约束的多条进离场程序,可以为进离场程序设计人员提供决策支持。

To effectively enhance the transport capacity in airport terminal airspace at the strategic level,an optimal design met-hod of multiple departure and arrival procedures was proposed,the airport layout and its surrounding environments were also considered.A three-dimensional(3D)modeling of procedures was carried out.Each procedure consisted of a smooth curve in the horizontal plane,associated with a fan-shaped area in the vertical plane.A conflict detection method adapting to the 3D model was proposed.An optimization algorithm for designing multiple departure and arrival procedures based on a modified-branch-and-bound method was developed.Results of simulation tests show that the proposed method can effectively generate multiple departure and arrival procedures,satisfying obstacle avoidance and route separation constraints.Thus it can support decision-making for procedure designers.
