【摘要】：針對微波與激光混合鏈路中繼衛(wèi)星在執(zhí)行初始調(diào)度方案過程中發(fā)生的各種動態(tài)擾動變化,分析研究各類擾動特點,把不同擾動下的動態(tài)問題歸結(jié)為一類復雜約束下的任務插入問題。建立混合鏈路中繼衛(wèi)星動態(tài)調(diào)度問題的約束滿足模型。提出基于啟發(fā)式信息的動態(tài)調(diào)度算法對模型進行求解,基于初始調(diào)度方案的優(yōu)良特性,極大降低動態(tài)調(diào)度復雜性。仿真結(jié)果驗證了模型和算法的可行性,能夠有效解決微波與激光混合鏈路中繼衛(wèi)星動態(tài)調(diào)度問題,對解決實際問題具有一定理論意義和現(xiàn)實意義。
[Abstract]:In view of the dynamic disturbance variation of microwave and laser hybrid link relay satellite during the execution of the initial scheduling scheme, the characteristics of all kinds of disturbances are analyzed and studied. The dynamic problems under different perturbations are reduced to a class of task insertion problems with complex constraints. A constraint satisfaction model for hybrid link relay satellite scheduling problem is established. A dynamic scheduling algorithm based on heuristic information is proposed to solve the model. Based on the excellent characteristics of the initial scheduling scheme, the complexity of dynamic scheduling is greatly reduced. The simulation results verify the feasibility of the model and algorithm, and can effectively solve the problem of dynamic scheduling of microwave and laser link relay satellite, which is of theoretical and practical significance to solve the practical problems.
