摘要: 运用可拓理论中基于参变量物元的动态评价模型,对机场安全预警模型进行了构建。首先根据调研建立了机场安全的预警评价指标体系,然后利用可拓关联函数方法确定各预警指标的权重,以综合关联度作为评价准则,最终根据模型确定出整体的预警等级,避免了预警模型的主观性。实例验证表明,该模型可针对机场安全状况提供有效的定量预警信息。

Abstract: A dynamic model based on variable matter element with parameters is applied to construct the early-warning model of airport safety.In this model,the early-warning indices system is conducted on the base of the survey.The weight of early-warning indices is ascertained with the method of correlation function in extension theory,and the comprehensive correlative degree is taken as the evaluation criteria.At last,the unitary early-warning grade of the airport is derived with the early-warning model.A case study shows that the model is suitable for evaluation of the airport safety,and for assisting early-warning decision quantitatively.

Key words: airport safety, early-warning model, extension theory, comprehensive correlative degree, correlation function in extension theory
