Towards dynamic real-time scheduling for multiple earth observation satellites
作者：
Highlights：
• Established a multi-objective dynamic scheduling model for real-time tasks.
• Proposed task dynamic merging and task “temporary” retraction strategies.
• Proposed DMTRH algorithm for dynamic real-time scheduling of multiple earth observation satellites.
• Made a trade-off between scheduling revenue, stability and energy conservation.
• Improved observation effectiveness and resource utilization of earth observation satellites.
