We present a detailed integrated simulation model for two processes: casualty transportation and emergency room
management after a major disaster. The two important processes have generally been discussed separately in literature.
However, to be able to correctly evaluate preparedness of disaster and emergency, and minimize potential loss of lives, it is
important that these two interconnected processes are analysed together. The purpose of this study is to present an
integrated simulation model of victim transportation and treatment processes after a major disaster and use the proposed
model in a case study for Bornova, a district of the city of İzmir in Turkey. Simulation model is run with a detailed
experimental design and results are statistically analysed. We find out and report the importance of correct distribution of
ambulances to regions and rules for better management of capacities of constrained medical resources in order to minimize
total loss of lives.
