Abstract:

A staged task planning method is put forward to solve the task planning problem of satellite and aerostat cooperative reconnaissance. The satellite and aerostat cooperative task planning is divided into three stages that are task clustering, task groups allocation and task scheduling. Firstly, a hierarchical clustering algorithm is used in task clustering by which several task groups would be produced. Secondly, the planning model of task group allocation which aims to build connections between task groups and resources is introduced. At last, a mixed integer planning model used in task scheduling is modeled and a corresponding particle optimize algorithm is introduced. By task scheduling, all tasks would be finally allocated to the specific platforms. The simulation results show that the proposed method is feasible and efficient.
