在軌衛(wèi)星的智能規(guī)劃可以歸結(jié)為資源受限的實時規(guī)劃和調(diào)度問題，由于此類問題的規(guī)
模大，實時性要求強，通常的解法很難滿足應用要求。本文針對該問題的特點，建立了問題的數(shù)學模型，包括知識表示、目標函數(shù)等。提出了三種啟發(fā)式的規(guī)劃算法，并對算法特點進行了比較分析，具體應用時，可以根據(jù)問題的不同特點選用相應的算法，從快速性和準確性兩方面適應系統(tǒng)要求。最后本文通過一個算例，從統(tǒng)計特性角度分析了三種算法，驗證了算法的正確性。

【Abstract】The intelligence scheduling and planning for on-board satellite belongs to scheduling problem under resources constrains. The problem is about large amount of tasks, and have tight real-time deadlines, so the common algorithm is hard to satisfy the requirement. This paper presents three kinds of heuristic algorithms, and make the fully analysis. In application, we can choose the proper algorithm base on the feature of the problem. Finally, Simulation results show the feasibility of the algorithm.
