小天体柔性着陆任务规划的动态时间约束推理方法

To address the complex coupled temporal constraint consistency reasoning problem in the planning of the small celestial body flexible landing mission，a mission planning temporal constraint network is constructed，temporal constraint types are classified，and a constraint dynamic addition strategy is established. A dynamic arc-consistent temporal constraint reasoning method is proposed to limit the propagation range of newly added constraints，locally solve the temporal network consistency，and maintain the temporal constraint network in the planning process dynamically. Finally，a small celestial body landing planning scenario is designed with the landing planning activities and temporal constraints. Simulation results show that compared with the existing temporal constraint reasoning method，the method in this paper improves the computational efficiency，which supports the planning of small celestial body flexible landing missions.
