智慧机场航站楼安全联检均衡分散方法仿真

目前航站楼安全联检均衡分散方法存在联检服务率低,开放服务台精准率低和长时间等待联检旅客比例过高的问题。为此提出智慧机场航站楼安全联检均衡分散方法,通过建立ARMA算法模型预测出单位时间内机场客流量,判断模型中获取到的客流量样本数据是否为稳定的时间序列,提取出相对合理的模型,最终在最小二乘法中加入阻尼项估计出模型的精度参数。假设预测的全部客流量都进行安全联检,令所有旅客的安检项目时间都分别独立,建立函数计算出旅客在安检口等待安检的时间概率,构建出联检均衡分散的目标函数,求解出目标函数就实现航站楼安全联检均衡分散。实验结果表明,所提方法的联检服务率高,开放服务台精准率高和长时间等待联检旅客比例低。

The Application of Weighted Association Rules in Host-Based Intrusion Detection System

Association rules are useful for determining correlations between items. Applying association rules to intrusion detection system (IDS) can improve the detection rate, but false positive rate is also increased. Weighted association rules are used in this paper to mine intrustion models, which can increase the detection rate and decrease the false positive rate by some extent. Based on this, the structure of host-based IDS using weighted association rules is proposed.
