Table 10: Visible time window for the initial missions and new missions. Figure 3 illustrates the statistical results of completed missions under the scenario with 30 missions. It can be seen that a total of 25 missions were completed after the dynamic scheduling due to the arrival of new missions. The missions with high priority (priorities level of 7, 8, 9 and 10) were all executed. Some missions with low priority (priorities level of 1, 2, 5 and 6) were not executed, because these missions were not allocated satellite resources during the initial scheduling or were replaced or deleted by a mission with higher priority in the dynamic scheduling. Overall, the proposed method guarantees a high execution rate for high-priority missions. The scheme change rate is 12% by calculating the model performance evaluation, so it is very helpful to guarantee the stability of the initial scheduling plan. Figure 4 shows that among the 25 executed missions, the missions with priorities higher than 6 account for 28% of the total number of completed missions, achieving a satisfactory scheduling effect.
