摘要
航路交叉口的管制调配一直是影响空管效率的核心问题,以往研究多是针对少量架次航空器进行分析,本论文在航迹运行(trajectory based operations,TBO)环境下,基于自主改航对航路交叉口处交叉航班流的预先冲突解脱方法进行研究.首先,基于航空器间水平安全间隔,转换计算航空器过交叉口时应保持的最小纵向时间间隔;其次,提出占用时间窗概念,建立基于占用时间窗的冲突检测模型,并考虑航班流通过时间最短制定综合通行原则,判定冲突中需要改航的航空器;最后,针对航班流通行中传统启发式算法时效性不足的问题,利用转弯角限制缩减可行解空间,并建立以改航时间最短为目标的改航点搜索模型,提高求解速度和搜索精度.以我国东北部典型高空扇区为例,验证所提方法在实际交叉航路运行下的有效性.仿真结果表明:所提冲突解脱方法的多米诺效应指数(domino effect parameter,DEP)相较于传统等待解脱方法降低了64.7%,且传统方法的解脱总用时为所提冲突解脱方法的7.6倍,所提解脱方法对空域稳定性的影响更小,解脱效率更高.
Control deployment at airway intersections has always been a core issue affecting the efficiency of air traffic control(ATC).Previous research has primarily focused on a small number of aircraft flights.As a result,a pre-conflict resolution method of large-scale cross-flight flow based on autonomous diversion in the trajectorybased operations(TBO)environment was proposed.Firstly,based on the horizontal safety interval between aircraft,the minimum longitudinal time interval that should be maintained when an aircraft crosses the intersection was converted;secondly,the concept of occupancy time window was proposed,and a conflict detection mechanism based on the occupancy time window was established.By integrating the principle of the shortest passage time for flight flows,a multi-objective decision-making model was established to achieve precise identification of conflicting aircraft and determine their priority for diversion.Finally,to address the issue of insufficient timeliness of traditional heuristic algorithms in flight flow movement,the feasible solution space was reduced by limiting the turning angles,and a search model for the diversion points was established to minimize the diversion time,thereby improving the solution speed and search accuracy.An example of a typical highaltitude sector in northeastern China was used to verify the effectiveness of the proposed method for actual crossroute operation.The simulation results indicate that the domino effect parameter(DEP)of the proposed conflict resolution method is 18.2%lower than that of the speed regulation resolution method.The total time consumption for speed regulation resolution is 7.6 times that of the proposed method.Therefore,the proposed method has a lesser impact on spatial stability and a higher resolution efficiency.
