Abstract：For emergency logistics management,decision making of supply distribution facility location is important. According to the uncertainties in emergencies,a two-stage robust optimization model for emer-gency facility location problems to achieve coordination between“pre-location”and“re-location”is pro-posed. In the first stage when demand,cost and facility disruption is uncertain,in the consideration of dif-ferent needs of pre-disaster planning,post-disaster response and facility re-location,a robust“pre-loca-tion”model is presented based on p-center model. In the second stage,with the acquisition of post-disas-ter information,a“re-location”model for building new facilities is presented based on reactive repairing and adjustment for previous strategies. A numerical study shows the model is more effective than traditional p-center model for emergency facility location.
