To solve the dynamic scheduling problem of Holonic-C2 organization collaborative resources, the emergencies on the battlefield are analyzed, and three basic kinds of emergent events, such as task attribute change, available platform reduction and task quantity change. The event-based Holonic-C2 organization double-layer structure cooperation mechanism, two multi-objective optimization models were constructed in the tactical decision-making Holon module, and the tactical Holon collaborative selection method was proposed in the operational decision Holon module. The simulation experiments show that the proposed Holonic-C2 organization collaborative resource dynamic scheduling process can effectively deal with the situation that a single tactic Holon can not handle emergencies, and realizes the cooperation of multiple tactical Holons, which proves the feasibility of the proposed method.
