The 2009 Padang earthquake resulted in 771 minor injuries, 431 serious injuries, and killed 383 people. The limited capacity for assistance forces victims to be placed in corridors, terraces, or emergency tents installed in hospitals. The Padang City Government estimates that 555,664 lives are at risk, with 29,520 minor injuries, 32,800 moderate injuries, and 131,201 serious injuries. Meanwhile, the number of health workers available is currently very limited. This study aims to determine hospitals, public health centers (puskesmass) and the number of temporary medical services (TMSs) to be opened, the number of victims, and the number of health workers (general practitioners, anesthetists, surgeons, and nurses) allocated to each health facility to minimize operational cost. The result of the model shows all existing hospitals and all puskesmass 84 TMSs in public hospitals and special hospitals, 20 TMSs in puskesmass and a dummy hospital. The objective function value obtained is IDR 5.62092 x 109. The operational cost include transportation cost for victims, transportation cost for health workers, and setup cost for opening temporary medical services. The results show that the operational cost will decrease along with the decrease in the number of victims in evacuation posts, causing a decrease in the total transportation cost of victims and the total transportation cost of health workers, but the total setup cost remains unchanged. The operational cost will increase along with the increase in the capacity of health facilities so that decreased in the total transportation cost of victims, increased in the total transportation cost of health workers, and the total setup cost remains unchanged.
