为了对枢纽机场航班延误进行有效预警,选用了5个预警指标构建了航班延误预警特征指标体系。利用可拓学的物元模型研究表现机场航班延误运行状态的指标之间的相互作用关系,建立延误情况评价指标,并采用可拓关联函数及可拓评价方法,对机场航班延误情况指标的可拓量化值进行预警评估。通过实例仿真,结果表明预警模型能够比较准确地反映机场的航班延误情况,为机场在协同决策系统中发布航班延误的预警情况提供科学的参考信息。 In order to effectively delay the flight delays at the hub airport, five early-warning indicators were selected to construct the flight delay warning index system. Using the matter-element model of extenics to study the interaction between the indicators of delayed flight status of the airport flight, establishing the evaluation index of the delay situation, and using the extension correlation function and the extension evaluation method, the index of the airport flight delay condition Extend the quantitative value of the early warning assessment. The simulation results show that the early-warning model can reflect the flight delays of the airport more accurately and provide scientific reference information for the airport to issue early warning of flight delays in the collaborative decision-making system.
