【摘要】：近年來,航空運輸業(yè)發(fā)展迅速,航班延誤及傳播問題也越來越嚴重�？刂坪蜏p少航班延誤是國內外民航管理工作的一個長期而艱巨的任務。通過分析航班運行數(shù)據(jù),挖掘數(shù)據(jù)的內在特征,找出航班延誤與波及的變化趨勢,對研究航班延誤問題具有重要指導意義�；趯桨嘌诱`問題的相關文獻的學習,本文從以下幾方面研究此問題:首先研究延誤沿著飛機資源傳播的問題,建立基于航班串的貝葉斯網(wǎng)絡模型模擬航班延誤波及和航班間延誤的相互關系,揭示不正常運營條件對航班計劃可靠性的影響。根據(jù)對航班運營可靠性的分析找出航班串中的薄弱環(huán)節(jié)即關鍵機場,運用加權馬爾科夫鏈模型對關鍵機場的整體延誤狀態(tài)進行預測,以反映機場隨機延誤因素對延誤在航班串中傳播的影響。從而更準確地預測航班延誤狀況,并根據(jù)預測結果對航班計劃進行相應調整,以提高航班計劃運營可靠性。其次考慮到飛機與機組是飛行的主要資源,一架飛機和一個機組在一天中往往要執(zhí)飛多個連續(xù)的航班,因此,如果航班串中一個航班發(fā)生延誤,延誤可能會沿著這兩種飛行資源波及到其下游航班�；谶@兩種飛行資源,提出了兩種資源分離方案,對兩種案例下的延誤因素對航班離港延誤的影響以及兩個案例的運營魯棒性進行對比分析,為航班延誤問題提供了有效的定量分析手段。最后,由于導致航班延誤的因素各種各樣,相應的航班延誤情況也相對復雜。在不同延誤因素或者不同延誤時長下,各延誤航班對應的服務也會有一定區(qū)別。通過對航空公司航班延誤評估,提出不同情況下的服務補救建議,如不同延誤時長情況下、不同延誤原因情況下等,以期提升航班延誤情況下服務保障。以上有關航班延誤波及的分析,能夠幫助相關部門進行航班延誤相關問題的管理決策。
[Abstract]:In recent years, with the rapid development of air transportation industry, the problem of flight delay and transmission is becoming more and more serious. Controlling and reducing flight delay is a long-term and arduous task of civil aviation management at home and abroad. Mining the inherent characteristics of the data and finding out the trend of flight delay and spread is of great significance to the study of flight delay. This paper studies this problem from the following aspects: firstly, the problem of delay propagating along aircraft resources is studied, and a Bayesian network model based on flight string is established to simulate the relationship between flight delay and flight delay. This paper reveals the influence of abnormal operating conditions on the reliability of flight plan. According to the analysis of the reliability of flight operation, we find out the weak link in the flight string, that is, the key airport. The weighted Markov chain model is used to predict the overall delay status of the key airports to reflect the impact of random delay factors on the spread of delay in flight strings, so as to predict the flight delay more accurately. According to the forecast results, the flight plan is adjusted accordingly to improve the operational reliability of the flight plan. Secondly, considering that the aircraft and crew are the main resources for flight, one aircraft and one crew often fly more than one continuous flight in a day. Therefore, if one flight in the flight string is delayed, the delay may spread to the downstream flight along the two flight resources. Based on these two flight resources, two resource separation schemes are proposed. The effects of delay factors on flight departure delay and the operational robustness of the two cases are compared and analyzed, which provides an effective quantitative analysis method for flight delay problem. Due to the variety of factors leading to flight delays, the corresponding flight delays are relatively complex. Under different delay factors or different delay periods, The service corresponding to each delayed flight will also be different. Through the evaluation of the flight delay of the airline, some suggestions for service remedy under different circumstances, such as different delay duration, different reasons for delay, etc., are put forward. In order to improve the service guarantee in the case of flight delay, the above analysis of flight delay ripple can help relevant departments to make management decisions on flight delay related issues.
