基于熵权物元可拓模型的航班恢复决策评价

Evaluation of Flight Recovery Decision Based on Entropy Weight Matter-element Extension Model

为了在协同决策机制下对航空公司运控人员就不正常航班恢复做出的决策进行科学性及有效性评估,结合航空公司实际情况,利用物元模型与可拓理论相结合的方法,从机组安全程度、机组疲劳程度、总体成本、服务保障能力和地面延误时间5个方面入手,构建不正常航班恢复决策评价体系。针对传统物元模型存在的不足,对物元模型的经典域和节域进行规格化处理。由于不正常航班恢复决策评估受主观因素影响较大,通过引入熵权法分析确定体系指标权重系数,以此来降低主观因素对评价结果的影响。并以定量结果证明不正常航班恢复决策的科学性和可行性。最后,通过案例仿真,证明该方法可以在协同决策机制下对不正常航班恢复决策进行有效评价。

In order to evaluate the scientificity and effectiveness of the decisions made by airline operators to resume abnormal flights under the collaborative decision-making mechanism,combined with the actual situation of the airline,the matter-element model combined with the extension theory is used.Starting from five aspects of crew safety,crew fatigue,overall cost,service guarantee capability and ground delay time,a decision-making evaluation system for abnormal flight recovery is constructed.In view of the shortcomings of the traditional matter-element model,the classical domain and the section domain of the matter-element model are normalized.Since the decision evaluation of abnormal flight recovery is greatly affected by subjective factors,the system index weight coefficient is determined by introducing the entropy weight method to reduce the influence of subjective factors on the evaluation results.And quantitative results prove the scientificity and feasibility of abnormal flight recovery decision.Finally,through case simulation,it is proved that the method can effectively evaluate the decision of abnormal flight recovery under the collaborative decision-making mechanism.
