Abstract: In order to conquer the state space exploring,Hierarchical Task Network(HTN) planning technology has been presented.In this paper,we give a description of formal representation of HTN problem and its operational semantics,then analyse the complexity of HTN and point out the strong and weak points in HTN planning technology.

Key words: automated planning, Hierarchical Task Network(HTN), formal representation, operational semantics

摘要: 为了克服经典状态空间规划中的状态空间的指数爆炸问题,研究者们提出了分层任务网络规划(HTN)技术。给出了HTN规划的形式表示,并给出了其操作语义,在此基础上讨论了HTN规划的复杂性,指出了HTN规划技术的优缺点所在。
