In order to solve the collaborative dynamic resource scheduling problem in Holonic-C2 organization, Firstly, the emergencies on the battlefield are analyzed, and three basic types of emergencies are given, such as changes in task attributes, reduction of available platforms, and changes in the number of tasks. We propose a collaborative mechanism based on the Holonic-C2 organization's two-layer structure to deal with emergencies. Two multi-objective optimization models are built for tactical decision Holon and a kind of tactical Holon selection method is provided for operation decision Holon. The simulation experiments show that the proposed Holonic-C2 organization collaborative dynamic scheduling method can effectively deal with the situation of that a single tactic Holon cannot handle emergencies well, and realizes the cooperation of multiple tactical Holons, which verifies the feasibility of the proposed method.
