Abstract:

In recent years, integrated scheduling methods for the telemetry, track and command (TT&C) tasks and data transmission (DT) tasks of ground stations have attracted more and more attention. To address the scheduling problem of station resources under the condition of random arrival of emergency TT&C and DT tasks, a multi-objective optimization model is established for the TT&C and DT tasks dynamic rescheduling. Then a rescheduling method based on heuristic rules and non-dominated sorting genetic algorithm Ⅲ (NSGA-Ⅲ) is designed, allowing to generate multiple alternative planning schemes focusing on different optimization objectives for users. The experimental results show that the proposed algorithm can effectively solve the multi-objective dynamic rescheduling proplem of measurment and control data transmission resources.

Key words: data transmission (DT) resource, telemetry, track and command (TT&C) resource, dynamic rescheduling, multi-objective optimization, evolutionary algorithm
