针对航空安全事故风险识别与评估问题,基于2019年航空安全事故,通过事件树分析方法分析风险事件间的因果关系,建立了有向加权航空安全风险网络模型。面对航空安全风险传播的情况,引入传染病模型对航空安全风险网络风险传播进行建模,对风险事件进行排序以实现航空安全风险识别,提出了航空安全风险网络风险指标与航空安全事故发生风险指标,以评估航空系统安全风险。结果发现,能见度差、飞机系统故障、设备维护不足、违规操作、疲劳、资源配置不当、应急响应措施不当、飞行准备不足、教育培训不足等应当引起管理者的关注。

在求解作业车间调度问题(job-shop scheduling problem, JSP)的局部搜索算法中,构造移动执行后的邻域解严重影响了局部搜索算法的计算效率.为此,基于拓扑排序和工序最大弧数的相关理论,提出了调度解拓扑排序的划分方法,实现了邻域解拓扑排序的构造;并在邻域解的拓扑排序中,准确地识别了邻域解中头和尾时间发生改变的工序集合,从而实现了邻域解的快速、动态构造.实验结果表明:相比于目前的邻域解构造方法,所提出的邻域解的动态构造方法,在计算速度上有着明显优势,且能够显著地节省计算时间.
