A goal planning method based on dynamic description logics used in Ad Hoc Workflow

Ad Hoc workflow is a workflow system which does not need to define the predefined workflow business process and organize migrating workflow union. In this case a single work place is unable to get the full system information, and the ability of the single work place in the system for goal decomposition and service understanding is limited. Some goals which can be completed by Ad Hoc Workflow System may be unknown for a certain work place. This paper focusing on the problem of Ad Hoc workflows goal planning for the unknown goal, presents a planning method of the unknown goal in Mobile Agent migration process. The method describes goals with Dynamic Description Logic, packages the unknown goal, and achieves dynamic goal planning. Goal Description, Goal Inference and methods and algorithms of dynamic goal planning are mentioned in this paper.
