The destructive impact of natural disasters emphasizes the importance of logistics and human resource planning in the pre- and post- disaster periods. In the event of a disaster, in order to provide immediate relief, the Health Hierarchical Network, which includes clinics and hospitals, will be activated. In this paper, using a mixed integer mathematical model and assuming the current location of hospitals and clinics, optimal locations are determined as temporary treatment emergency centers and the optimal allocation of casualties from urban areas to these centers and then clinics and hospitals are recommended in disaster. Using the simulation model, the moment of disaster and the rescue process were simulated and then the optimization approach was adopted based on simulating the optimal capacity of temporary centers and improving the capacity of current centers and hospitals. The results of the study show that the hierarchical model of location allocation of capacity optimization reduces the density of casualties, costs and treatment time in disaster.
