为准确评估签派可靠度高低对航空公司造成的经济性影响,针对民机系统建立飞机系统签派可靠度评估模型,运用贝叶斯理论对模型中参数进行估计。引入航空公司延误损失函数,研究因系统签派可靠度差异所造成的航空公司经济损失,得出民机系统签派可靠度经济性评估方法。以航空公司A320机队运营数据作为基础,以导航系统为例进行验证,量化了民机系统签派可靠度所代表的经济性。
為準確評估籤派可靠度高低對航空公司造成的經濟性影響,針對民機繫統建立飛機繫統籤派可靠度評估模型,運用貝葉斯理論對模型中參數進行估計。引入航空公司延誤損失函數,研究因繫統籤派可靠度差異所造成的航空公司經濟損失,得齣民機繫統籤派可靠度經濟性評估方法。以航空公司A320機隊運營數據作為基礎,以導航繫統為例進行驗證,量化瞭民機繫統籤派可靠度所代錶的經濟性。

In order to accurately assess the economic impact caused by the dispatch reliability , estab-lishedthe reliability assessment model of the systems of Civil Aircraft based on Bayes Method .Introducing the delay′s loss function of Airline to research the economic loss causedthe dispatch reliability of the sys-tems.Concluded the economic assessment method of the dispatch reliability for the system of Civil Air -craft,based on the operation data of a fleet for A 320 of the airlineand verified the navigation system as an example.Quantify the economic represented by the dispatch reliability of the civil aircraft systems .
