| 中文摘要: |
| 针对微波与激光混合链路中继卫星在执行初始调 度方案过程中发生的各种动态扰动变化,分析研 究各类扰动特点,把不同扰动下的动态问题归结为一类复杂约束下的任务插入问题。建立混 合链路中继 卫星动态调度问题的约束满足模型。提出基于启发式信息的动态调度算法对模型进行求解, 基于初始调 度方案的优良特性,极大降低动态调度复杂性。仿真结果验证了模型和算法的可行性,能够 有效解决微 波与激光混合链路中继卫星动态调度问题,对解决实际问题具有一定理论意义和现实意义。 |

| Aiming at the dynamic disturbance conditions of the data relay satelli te with microwave and laser hybrid link during initial scheduling scheme,based on the analysis o f the disturbance resulting in the dynamic scheduling,the dynamic scheduling problem under different disturbances b ecomes a kind of mission insertion problem under complex constraints.The constraints-satisfied m odel is formulated.The dynamic scheduling algorithm based on heuristic information is proposed to solv e the problem.Taking advantage of the eminent performance,the complexity of the dynamic scheduling p roblem is reduced.The simulation results show that the model and algorithm are feasible and can solve th e practical problem when disturbances happen. |
