The location of emergency systems and the emergency evacuation strategy were introduced and the recent advances of the study in this area were analysed.In fact,there are commonly many uncertain factors during the decision making process in emergency management.The outcome of emergency depends usually on the effects of two or more factors.A method of pursuitevasion differential games with two targets was proposed to study the emergency evacuation with several security points.Escaping individual was regarded as a dynamic system and as one party of differential games while the uncertain factors as the other party.The solution of the differential game was obtained through constructing Hamilton functions.
