Early-Warning Model of Airport Security Based on Extension Theory

A dynamic model based on variable matter element with parameters is applied to establish the early-warning model of airport security. 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 the evaluation of the airport security, and the assisting early-warning decision quantitatively.
