The observation scheduling problem with multi-task and multi-resource for multi-satellites is studied in this paper. Firstly, the time constraints and resource constraints remain in the scheduling process are analyzed, and the mathematical model for the scheduling problem is established. Secondly, the ways of checking the time and resource constraints are respectively given, especially for the resource with both producing and consuming functions. Finally an improved ACO is proposed, combining with the task priorities and resource constraint information, proper transition controlling strategy and pheromone updating mechanism. The simulation proves the validity of the model and the algorithm.
