摘要

摘要: 硬X射线调制望远镜（HXMT）卫星是中国首颗空间X射线天文卫星.为充分利用卫星资源，使科学产出最大化，需要进行长期任务规划.长期任务规划是一个复杂的多目标优化问题.通过分析HXMT观测特点和约束条件，建立了HXMT长期任务规划问题模型，并采用贪婪算法加遗传算法对模型进行求解.实例分析结果表明该方法能够有效解决HXMT长期任务规划问题.

Abstract: Hard X-ray Modulation Telescope (HXMT) satellite is China's first space X-ray astronomy satellite. The planning and scheduling of HXMT observations is a complex multi-objective optimization problem, and the optimization object is to maximize simultaneously the scientific return and the observation efficiency. By analyzing the characteristics of HXMT observations and all the important factors in the efficient scheduling of a celestial source, such as celestial constraints and the additional scientific constraints, the HXMT long-term planning model is established. The greedy algorithm and genetic algorithm are combined to solve the model. Simulation results show that the approach is effective in solving the HXMT long-term planning problem, based on the analysis of the first year observations of Suzaku Mission.
