Scheduling for observations of deep space spacecraft under uncertainty

以不确定性条件下的深空探测器观测调度问题为研究对象,首先分析了深空探测任务的背景特点,指出深空探测活动具有高度不确定性,进而全面分析了深空探测器观测调度中的不确定性因素,提出了基于鲁棒调度和动态重调度的深空探测器调度体系,并针对其中的动态重调度单元进行了深入研究。详细设计了改进的混合动态重调度策略和基于群体智能的深空探测器动态重调度方法,最后提出了基于时间成本、效率和稳定性的重调度性能评价体系。

Focusing on the scheduling for observations of deep space spacecraft under uncertainty,the characteristics and background of deep space exploration mission are analyzed first.Then the uncertain factors of observations of deep space spacecraft are fully investigated.A hybrid scheduling strategy based on robust scheduling and dynamic rescheduling is proposed.Furthermore,the dynamic rescheduling unit is studied in-depth.Details of the improved hybrid rescheduling strategy and the swarm intelligence based rescheduling method for observation rescheduling of deep space spacecraft are presented.Finally,a performance evaluation system based on time cost,efficiency and stability is established.
