航空发动机的可靠性要求高，监测性能参数是了解航空发动机性能和可靠性的重要手段。根据性能参数的变化，描述航空发动机的性能退化过程，并且考虑了退化信息之间的相关性，建立基于多元退化信息的可靠性预测模型。将多性能参数作为航空发动机的退化信息，预测了相关条件下的航空发动机机队可靠性；并与假定的独立条件下的可靠性预测作比较，通过算例说明本方法的有效性。
航空髮動機的可靠性要求高，鑑測性能參數是瞭解航空髮動機性能和可靠性的重要手段。根據性能參數的變化，描述航空髮動機的性能退化過程，併且攷慮瞭退化信息之間的相關性，建立基于多元退化信息的可靠性預測模型。將多性能參數作為航空髮動機的退化信息，預測瞭相關條件下的航空髮動機機隊可靠性；併與假定的獨立條件下的可靠性預測作比較，通過算例說明本方法的有效性。

The requirement of the reliability of aircraft engine is high. The performance of aircraft engine can be known by the important means of monitoring the performance parameters. By the changes of the performance parameters,the degradation process of aircraft engine is described with considering the dependence during the multivariate degradation information,the model about the reliability prediction based the multivariate degradation information is developed. Multivariate performance parameters as the degradation of the aircraft engine information predict the reliability of the fleet of aircraft engine for the dependence conditions,which is compared with the reliability prediction of the assumed independent condition,the .case shows the method is effective.
