Abstract:

Considering pop-up missions in space station operation, a re-planning method based on heuristic algorithm is proposed to satisfy the requirement for fast responses of mission re-planning. According to the continuity characteristic and conflict condition in mission execution, a model for space station pop-up mission planning domain is constructed. Considering the propagation effects of complicated constraints between the activities of missions, the time backtrack iteration strategy is adopted to solve the conflicts, and then an interval time heuristic algorithm is proposed according to the interval time between missions' execution.A fast response to the pop-up mission is achieved using the time backtrack iteration strategy and the interval time heuristic algorithm to re-plan the missions. The results show that the proposed mission re-planning method can successfully satisfy the requirement for pop-up mission planning and real-time updating of the onboard mission list.
