Abstract:

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.
