POST-EARTHQUAKE RELIEF LOGISTICS CENTER LOCATION SELECTION: A NOVEL HYBRID IT2 F-RANCOM + IT2 F-MOORA APPROACH

Abstract

The selection of post-disaster humanitarian logistics centers plays a critical role in ensuring the rapid and effective delivery of aid in affected regions. This study aims to develop and implement the proposed hybrid model that can more effectively model uncertainties in post-earthquake humanitarian logistics center location selection. The province of Hatay, one of the areas most severely affected by the 2023 Kahramanmaraş-centered earthquakes, was selected as the case study area. Six evaluation criteria and five alternative regions were considered. Initially, the fuzzy performance values of the alternatives were calculated using the IT2 F-MOORA method. Subsequently, the final ranking was obtained through reference-normalized values using the IT2 F-RANCOM method. The results indicated that A2 (Northern Hatay Region) was the most suitable alternative with a score of 1.000, followed by A1 (Central Hatay Region) with 0.950 and A3 (Eastern Hatay Region) with 0.732. A sensitivity analysis was conducted by varying the weight of the reference criterion C1 (Disaster Risk) between +15% and +65% in increments of +10%. The analysis showed that the proposed hybrid approach maintained ranking stability. Even under maximum weight variation, A2 remained the most suitable location, and no changes occurred in the ranking of the other alternatives. This indicates that the proposed model is resilient to uncertainties and provides policymakers with a reliable decision support tool for post-disaster logistics planning.

DEPREM SONRASI YARDIM LOJİSTİK MERKEZİ YERİ SEÇİMİ: YENİ BİR HİBRİT IT2 F-RANCOM + IT2 F-MOORA YAKLAŞIMI

Abstract

Deprem sonrası yardım lojistik merkezi seçimi, insani yardımların hızlı ve etkin ulaştırılmasında kritik rol oynar. Bu çalışmanın amacı, bu probleme yönelik belirsizlikleri etkin şekilde modelleyen önerilen hibrit modeli geliştirmek ve uygulamaktır. Çalışma alanı olarak, 2023 Kahramanmaraş merkezli depremlerinden en fazla etkilenen illerden biri olan Hatay ili seçilmiştir. Değerlendirme sürecinde altı kriter ve beş alternatif bölge dikkate alınmıştır. İlk aşamada IT2 F-MOORA yöntemi ile alternatiflerin bulanık performans değerleri hesaplanmış, ardından IT2 F-RANCOM yöntemi ile referans normalize değerler üzerinden nihai sıralama yapılmıştır. Elde edilen sonuçlara göre, A2 (Hatay Kuzey Bölgesi) 1.000’lık skor değeriyle en uygun alternatif olarak belirlenmiştir. Bu alternatifi A1 (Hatay Merkez Bölgesi) 0.950 ve A3 (Hatay Doğu Bölgesi) 0.732 skorlarıyla takip etmektedir. Ayrıca, referans kriter olarak alınan C1 (Afet Riski) kriterindeki ağırlık değerine +%15 - +%65 aralığında +%10 oranlarında yapılan duyarlılık analizi sonucunda, önerilen hibrit yaklaşımının sıralama kararlılığını koruduğu gözlemlenmiştir. En yüksek ağırlık değişiminde dahi A2 alternatifi en uygun lojistik merkezi olarak konumunu sürdürmüş, diğer alternatiflerin sıralamasında herhangi bir değişiklik olmamıştır. Bu durum, önerilen modelin belirsizliklere karşı dayanıklı olduğunu ve politika yapıcılarına afet sonrası lojistik planlamada güvenilir bir karar destek aracı sunacağını göstermektedir.
