为了有效地获取和利用领域知识,提高规划效率,分析了工作流模型和分层任务网络(HTN)规划领域模型的相似性,提出了一种采用工作流模型进行规划领域建模,对领域知识进行获取和表达的方法.工作流模型中的行动和工作流模式,转换为HTN规划中的行动和任务分解;另外,引入了循环(Loop)工作流模式,转换为HTN规划中的递归调用,扩展了工作流模式对规划领域知识的表达能力.在典型的几个规划领域中,引入领域知识后大大提高了规划器的求解效率,从而验证了应用工作流模型进行规划领域建模的有效性.

In order to improve planning efficiency by acquiring and utilizing domain knowledge, workflow process models were compared along with hierarchical task network (HTN) planning domain models, and a new method was presented based on the workflow to model planning domain. Activities and workflow patterns were respectively translated into actions and composed tasks in the HTN domain. Loop pattern was introduced to represent recursion in the HTN domain in order to extend the knowledge acquisition and representation abilities of workflow patterns. In experiments on several classical planning domains, such knowledge acquired in workflow models was shown to speed up the classical planner by several orders of magnitude. The experiments validate the HTN planning domain modeling method using a workflow model.
