Izmir (2020) and Elazig (2020) earthquakes, where 118 and 41 deaths and thousands of
affected people were recorded in Turkey, have been important reminders for the expected earthquake
in Istanbul, Turkey. In Marmara Earthquake (1999), one of the most devastating disasters recorded in
the last century in Turkey, the intensive influx of casualties was a significant problem encountered at
healthcare facilities. After a large-scale disaster, the sudden increase in demand at healthcare facilities
can lead to increase in the number of losses. In this study, we suggest opening temporary emergency
treatment facilities in order to enhance the rapidness and effectiveness of emergency response
operations for the first 72 hours aftermath of a disaster. Furthermore, the utilization of existing
hospitals and the impact of injury level of victims on the service capacity are investigated in the
presented model. A multi-objective, multi-period, mix-integer mathematical model is developed to
minimize the total distance travelled by casualties and the cost of opening temporary emergency
facilities. We conducted a real-case study for a district in Istanbul, Bakirkoy to demonstrate how the
proposed model can be applied in practice. By weighted-sum method, results provide various choices
related to the number and location of temporary emergency units by considering trade-off between
two conflicting objective functions. This work was supported by Yildiz Technical University Scientific
