Study on Emergency Scheduling Model of Space and Ground TT&C Resources
The scheduling of space and ground TT&C resources is an optimization problem with complex constraints such as multi-time windows and long-time windows.In the actual TT&C resource management activities, the arranged TT&C network plan needs to be adjusted in emergency, such as the spacecraft in abnormal or the TT&C devices in malfunction.Based on the practical applications, the workflow of emergency scheduling of space and ground TT&C resources is designed.Taking the adjustment as scheduling decision variable, the emergency scheduling model and algorithm of TT&C resources is established corresponding to our TT&C network management mode, which minimize the change range of network plan and maximize the task satisfaction rate, and then the evaluate function is also provided.Simulation result demonstrates that the model and algorithm are feasible for emergency scheduling of TT&C resources to ensure the task completion of the whole TT&C network.
