Coupling Evaluation Model of Abnormal Flight Recovery Strategy

Abnormal flight operations leading to a low on-time performance rate have become a significant bottleneck in the development of civil aviation transportation. Therefore, effective management of these irregular flights is essential. Taking into account the practical experience of flight dispatchers within the airline's operations control center, it is crucial to thoroughly evaluate the effectiveness of the recovery strategy for abnormal flights and ensure that the decision-making process is highly executable. First, assess the primary factors affecting the abnormal flight recovery process. Based on this assessment, establish an evaluation system for abnormal flight recovery strategies. To mitigate uncertainty in handling evaluation indicators during the assessment, we introduce matter-element extension analysis and set pair analysis methods to construct an evaluation model. Finally, in the real-world abnormal flight management process, we have chosen to analyze abnormal flight cases involving A321 civil aviation aircraft. The findings demonstrate that the evaluation model presented in this article adeptly manages indicator uncertainties, delivering a scientifically sound and effective evaluation tool for the operation control center.
