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.
