[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.
