This paper proposes a flexible plan representation framework for agile organization. Based on the characteristics analysis of the plan in agile organization, we propose a four-layer framework, which supports a plan to bind action, actor and resource dynamically, as well as to improve the adaptability to the change of mission and environment by case-based and rule-based dynamically intelligent planning mechanism. In order to exchange information correctly and rapidly, information routing is introduced into this framework. An application model of this representation framework is investigated and a use case in e-manufacturing is given as a practical example. Thus, this framework can provide more flexibility for integration of heterogeneous planning systems and of planning systems and manufacturing execution system.
