机场的安全设计

Security design for airports

解决的是一个航空安全方案的优化问题,以提高航空安全水平为主要目标,先以排队论为基础,建立了对A、B两个中西部最大的机场在高峰期不同上座率的情况下EDS的使用数量的优化模型,得到上座率为100%时A、B机场分别采用17、18台EDS,然后用图像逼近的方法检验了优化值,将其推广到整个中西部的193个机场,并得到EDS数量与客流量的对应表,知A、B机场在一般情况下则分别采用14、15台EDS.

In this paper, the optimal number of EDS and ETD for airports is presented,with flight security as the main objective. First,a model is developed to calculate the number of EDS based on queuing theory,which gives the different numbers of EDS according to occupancy rate. Thus, the numbers of EDS at Airport A&B are 17,18 during a peak hour separately. Considering that the occupancy rate is always less than 100%, 14 and 15 become the better results. This optimum was verified through photograph approaching, and then model was applied to 193 airports in the Midwest Region.
