【摘要】:我國航空運輸業(yè)進入了快速蓬勃的發(fā)展階段,航空客貨運輸量和飛行架次逐年攀升。迅速增長的空中交通量使我國面臨著航路結(jié)構(gòu)復雜、主要航路擁堵的困境,尤其是在高峰時間和惡劣天氣情況下,當前的航路網(wǎng)絡(luò)(ARN)表現(xiàn)出效率低、靈活性差的弊端,從而導致了大面積航班延誤和安全運行壓力增大。因此,針對這些問題,如何優(yōu)化航路網(wǎng)絡(luò)布局,提高運行容量和安全性,成為亟待解決的重要課題。 本文主要研究了航路網(wǎng)絡(luò)規(guī)劃的一些關(guān)鍵技術(shù)問題,首先介紹了航路網(wǎng)絡(luò)規(guī)劃原則和流程,建立了航路網(wǎng)絡(luò)評價指標體系;其次對航路網(wǎng)絡(luò)節(jié)點進行建模分析,引入差分進化算法對模型進行求解,采用多目標法與約束違反程度相結(jié)合處理約束條件,在模型求解過程中選用標準差分進化機制,使不滿足沖突約束的個體與滿足約束的個體有同樣的概率進入下一代,充分利用不滿足約束個體提供的有用信息,降低了聯(lián)賽選擇算子的局限性,進一步提高了得到全局最優(yōu)解的概率;然后根據(jù)北京飛行情報區(qū)空域環(huán)境,針對現(xiàn)有航路網(wǎng)絡(luò)布局問題,,對該區(qū)域內(nèi)航路網(wǎng)絡(luò)交叉點重新布局,將連接度高且各航段流量大的交叉點進行分解,在空中交通流量一定的情況下,降低了一些大流量交叉點的沖突數(shù),提高了航路網(wǎng)絡(luò)的安全性,降低了航路網(wǎng)絡(luò)的運行成本;最后提出了一種新型的航路結(jié)構(gòu)-高速航路,探討其在現(xiàn)行空域環(huán)境中運行的可操作性,在京滬穗三地間引入這種航路結(jié)構(gòu)以期解決當前三地之間航路容量瓶頸問題。
[Abstract]:China's air transport industry has entered a rapid and vigorous stage of development, the volume of air passenger and cargo traffic and flight sorties are rising year by year. With the rapid increase of air traffic volume, our country is faced with the difficulties of complicated air route structure and congestion of main routes. Especially in the rush hour and bad weather, the current air route network (ARN) shows the disadvantages of low efficiency and poor flexibility. This resulted in a large area of flight delays and increased pressure to operate safely. Therefore, to solve these problems, how to optimize the route network layout, improve the capacity and security, has become an important issue to be solved. This paper mainly studies some key technical problems of route network planning. Firstly, it introduces the principle and flow of route network planning, establishes the evaluation index system of route network, and then analyzes the model of the network node. The differential evolution algorithm is introduced to solve the model. The multi-objective method combined with the degree of constraint violation is used to deal with the constraint conditions, and the standard deviation evolution mechanism is chosen in the process of solving the model. So that the individuals who do not meet the conflict constraints have the same probability to enter the next generation as those who meet the constraints, and make full use of the useful information provided by the individuals who do not meet the constraints, thus reducing the limitation of the league selection operator. The probability of obtaining the global optimal solution is further improved, and then according to the airspace environment of the Beijing flight information region, the intersection points of the air route network within the region are rearranged according to the existing route network layout problem. By decomposing the intersections with high degree of connection and large volume of traffic in each section, the number of conflicts at some large traffic intersections is reduced under the condition of certain air traffic flow, and the safety of the air route network is improved and the running cost of the network is reduced. At last, a new type of route structure, high speed route, is put forward, and its maneuverability in the current airspace environment is discussed, and the route structure is introduced between Beijing, Shanghai and Guangzhou in order to solve the bottleneck problem of the capacity of the route between the three places.
