Abstract：The departments involved in emergency decision-making are required to perform coordinated planning for a global action plan. The coordination of using emergency resource is a key issue of coordinated planning for an valid emergency response plan. In order to handle the real-time generated emergency resource conflict along with the distributed planning process, an hierarchical task network (HTN) planning process based multi-agent distributed coordinated planning method is designed. The method embeds the coordination process into hierarchical task network (HTN) planning process with the consideration that the action plan generation process should also be coordinated. This method can reduce the generation of useless plan and improve the efficiency of cooperation. Additionally, the coordination mechanism dealing with the reusable resources is developed, and a variety of priority rules are used to resolve resource using conflicts. Next, based on these designs, an hierarchical task network (HTN) based coordinated planning algorithm is proposed and implemented. Finally, an experimental study was presented to demonstrate the application of emergency resource coordinated planning and the validity and the efficiency of the method.
