Bulanık Choquet İntegral Yöntemini Kullanarak Bir Covid-19 Sahra Hastanesi İçin Yer Seçimi

COVID-19 salgını sırasında sahra hastanelerine olan ihtiyaç büyük ölçüde artmıştır. Bir sahra hastanesinin yeri, hastaların hastaneye erişimini doğrudan etkilediği için yetkililerin aldığı muhtemelen en kritik karardır. Bu çalışma, Türkiye'nin üçüncü büyük şehri olan İzmir'de kurulacak COVID-19 sahra hastanesi için en uygun konumu belirlemeyi amaçlamaktadır. Dilsel değerlendirmelere izin veren bir çok kriterli karar verme tekniği olan Bulanık Choquet Integrali, sahra hastanesi için alternatif konumları değerlendirmek için kullanılmıştır. Bu yöntem ayrıca kriterler arasındaki etkileşimi de dikkate alarak genel bir ağırlık elde etmektedir. Bununla birlikte karar vericilerin her bir kriteri değerlendirirken aralıklı değerler kullanabilmesi öznel karar verme aşamasındaki hataları ortadan kaldırmaktadır. Yöntemde son olarak her bir kriterin hangi alternatif için en iyi tercih edilebileceği sonucu da elde edilebilmektedir. Çalışmada, İzmir'deki dört alternatif konumun (Bornova, Karşıyaka, Konak ve Buca) genel ağırlık değerleri belirlenmiş ve en yüksek genel ağırlık değerine sahip olan Bornova alternatifi en uygun konum olarak önerilmiştir.

Location Selection for a Covid-19 Field Hospital Using Fuzzy Choquet Integral Method

The need for field hospitals increased drastically during COVID-19 pandemic. Location of a field hospital is probably the most critical decision taken by government authorities since it directly affect the patients' access to the hospital. This study aims to determine the most suitable location for a COVID-19 field hospital to be constructed in İzmir, the third largest city of Turkey. Fuzzy Choquet integral multi criteria decision making technique that allows for linguistic assessments is used to evaluate the alternative locations for the field hospital. This method also obtains a general weight by taking into account the interaction between the criteria. Besides, decision-makers can use interval values while evaluating each criterion and thus this process eliminates errors in subjective decision-making. Moreover it is also possible to obtain the result for which alternative is the best preferred for each of criterion. Overall weight values of four alternative locations in İzmir (i.e., Bornova, Karsiyaka, Konak and Buca) were determined and Bornova alternative with the highest overall weight value was proposed as the most suitable location for the field hospital.
