- Abstract:
-
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.
