Abstract: Emergency decision-making is the basis and core of emergency management HTN planning provides an effective mean for it and is the hot issue of current research. According to the hard problem of modeling the domain knowledge during the process of solving the emergency decision making problem based on H TN planning, on the foundation of modeling the emergency plan using workflow model based on PetriNet,this paper presented a method of translating the emergency plan template to the H I}N planning domain knowledge model. I}hen, we modeled the emegency decision- making problem as a mission-planning problem, used the H I}N planning system SHOP2 to solve it, and realized to make action plans by selecting and organizing emergency plan segments scientifically in the face of complex situation. Finally,we carry out the application research in the flood response work of some area.
