Abstract: Emergency plans are the substantial foundations to deal with emergency incidents.Emergency plan systems，which are organized sets that are composed of interrelated emergency plans，provide guides for enacting and revising emergency plans.However，the management of emergency plan system is faced with some challenges.The knowledge description of emergency plan systems do not have unambiguous and uniform expressions and result in the semantics clash.Different emergency plan systems can not cooperate，share and reuse each other.In this paper，Emergency Plan System Ontology（EPSOnto） is designed by using SUMO as upper ontology in order to solve these problems.EPSOnto can provide the knowledge share in semantics to achieve the cooperation and reuse between people and the different systems.In EPSOnto the concepts，relations，functions，axioms and instances about emergency plan systems are respectively described in five-tuple in detail.In the end，the experiment of an emergency plan system is completed to validate EPSOnto.
