| Abstract: | For satellite data transmission scheduling problems, a system framework of tasks scheduling heuristics is founded. Heuristics based on task start time, task scheduling profits, the flexibility of task available resources and the conflict degree of task scheduling are proposed, and the application of tasks scheduling heuristics in ant colony optimization algorithm for satellite data transmission is researched. Simulation results of different scale scenarios show that tasks scheduling heuristics can help the ant colony algorithm solve satellite data transmission scheduling problems. |
