成像卫星鲁棒性调度策略研究

Research on robust scheduling strategy of imaging satellites

针对不确定条件下的成像卫星调度问题,分析了鲁棒性调度要求,提出了鲁棒性调度策略,将成像卫星调度分为鲁棒性调度方案生成和鲁棒性调度方案动态调整两个阶段。在鲁棒性调度方案生成阶段,以调度方案收益和鲁棒性为优化目标,建立了成像卫星鲁棒性调度模型。在鲁棒性调度方案动态调整阶段,以调度方案收益和新老调度方案差异为优化目标,建立了成像卫星动态调度模型。仿真实例验证了成像卫星鲁棒性调度策略和模型的有效性。

To resolve the imaging satellite scheduling problem with uncertainness, the demand for robust scheduling is analyzed, and a robust scheduling strategy of imaging satellites is proposed to devide the whole problem into two phases including the creation of robust solution and the dynamic adjustment of robust solution. In the first phase, an imaging satellite robust scheduling model with the optimized objects of solution gain and solution robustness is presented. In the second phase, an imaging satellite dynamic scheduling model with the optimized objects of solution gain and solution difference is presented. Numerical results indicate the validity of the robust strategy and models.
