【摘要】：民航运输的快速发展,为人们的出行带来了巨大的便利,机场建设对于提升地区经济品质也起到了良好的带动作用,然而,不正常航班及延误问题日益凸显,而这也直接关系到民航整体服务质量的提高与和谐民航建设的成败。在面对流量快速增长时,如何进行有效、高效的管理,就显得尤为重要。本文选取成都地区作为研究对象,完成了对成都双流机场未来几年旅客吞吐量的预测,阐述了成都空中走廊的划分并给出了使用建议。统计数据表明,由于机场原因造成不正常航班的数量较少,且国内针对机场方面(如地面等待)开展了大量的研究,本文着重从管制扇区角度对流量调配策略展开研究。论文首先对造成空域拥堵的原因进行了统计,选用灰色关联理论对不同原因之间的相关性进行了定量计算、分析,并作为下一步空域繁忙程度评判考虑的考核指标。论文以管制扇区为单位,构建评价因子集和评语集,确定权重及隶属度,采用层次分析法及模糊综合评价法,完成对管制扇区繁忙程度的评价。基于对扇区繁忙程度的评价,论文以成都终端及区域管制扇区为例,对扇区动态管理展开研究。根据边界点、航路点、导航台经纬度坐标生成终端空域结构图及成都区域管制扇区图,继而以航路点、导航台为生成元,构建成都终端、区域Voronoi图。由于航路点的重要性不同,对其权重进行分析,剔除部分生成元,生成加权Voronoi图。对不同时段、不同生成元的工作负荷进行统计,计算所需扇区数量,结合区域生长算法,实现扇区的动态管理。研究结果表明,基于关键节点的流量调配策略研究,在提高运行效率的同时,有效利用了空域资源,为扇区繁忙度评估、扇区动态管理提供了一定的理论和技术指导。
[Abstract]:The rapid development of civil aviation transportation has brought great convenience for people to travel. Airport construction has also played a good role in promoting the regional economic quality. However, the problem of abnormal flights and delays has become increasingly prominent. This is also directly related to the improvement of the overall service quality of civil aviation and the success or failure of harmonious civil aviation construction. In the face of rapid growth of traffic, how to carry out effective and efficient management, it is particularly important. In this paper, Chengdu area is selected as the research object, the passenger throughput of Chengdu Shuangliu Airport is predicted in the next few years, the division of Chengdu air corridor is expounded and some suggestions are given. Statistical data show that the number of abnormal flights due to airport reasons is relatively small and a large number of studies have been carried out on the airport (such as ground wait). This paper focuses on the flow allocation strategy from the perspective of the control sector. Firstly, the paper makes statistics on the causes of airspace congestion, and uses grey correlation theory to calculate and analyze the correlation among different causes, which is considered as the assessment index of airspace busy degree in the next step. The paper takes the regulated sector as the unit, constructs the evaluation factor set and the comment set, determines the weight and the membership degree, uses the analytic hierarchy process and the fuzzy comprehensive evaluation method, completes the evaluation to the control sector busy degree. Based on the evaluation of sector busyness, this paper takes Chengdu terminal and regional control sector as an example to study the dynamic sector management. According to the boundary point, the route point, the navigation station latitude and longitude coordinate generation terminal spatial domain structure chart and the Chengdu area control sector chart, then takes the route point, the navigation station as the generator, constructs the Chengdu terminal, the region Voronoi chart. Because of the different importance of the route point, the weight of the route point is analyzed, the partial generator is eliminated, and the weighted Voronoi diagram is generated. The workload of different generators in different periods is counted, the number of sectors needed is calculated, and the dynamic management of sectors is realized by combining the region growth algorithm. The results show that the research of traffic allocation strategy based on key nodes not only improves operation efficiency, but also effectively utilizes spatial resources, which provides some theoretical and technical guidance for sector busyness evaluation and sector dynamic management.
