To cite this document ABSTRACTPurpose-Optimum location of warehouses for disaster logistics increases the performance of humanitarian logistics, so that all the needs of beneficiaries can be delivered in a short time. In this paper, a multi-criteria decision analysis model is designed to decide the best warehouse location in disaster logistics in Trabzon, Turkey. Methodology-Entropy is used to determine the important weights of the criteria. The SAW, TOPSIS and VIKOR methods are utilized to rank the warehouse location alternatives. The ranking results are also combined by the Borda Count method to obtain a final ranking. The robustness of the model is examined by the sensitivity analysis. Findings-According to the results of the analysis, the disaster situation of the land, land size, and the distance of settlement were determined as the three most important criteria. Sensitivity analysis also proved the robustness of the model. Conclusion-The results are consistent with the expectations of the decision makers and seem to support their decisions. For future studies, the results can be compared using fuzzy techniques.Keywords: Disaster logistics, warehouse location decision, multicriteria decision making techniques. JEL Codes: C44, L81, Q54 AFET DEPO YERİ SEÇİMİ İÇİN ÇOK KRİTERLİ KARAR ANALİZİ MODELİ ÖZETAmaç-Afet lojistiği kapsamında depoların en uygun yerlere kurulması, insani yardım lojistiğinin performansını artırarak afetzedeler için gerekli tüm malzemelerin kısa bir sürede ihtiyaç yerlerine ulaştırılmasını sağlamaktadır. Bu çalışmada, Trabzon'da afet lojistiği kapsamında en uygun depo yerinin belirlenmesi amacıyla bir çok kriterli karar analizi modeli tasarlanmıştır. Yöntem-Bu model kapsamında ilk olarak Entropi Tekniği yardımıyla kriter ağırlıkları hesaplanmış ve ardından alternatif depo yerleri, çok kriterli karar verme teknikleri olan SAW, TOPSIS ve VIKOR kullanılarak sıralanmıştır. Elde edilen sonuçlar, Borda Sayım yöntemi kullanılarak bütünleşik bir sıralama elde edilmiştir. Ayrıca, son aşamada gerçekleştirilen duyarlılık analizi ile modelinin uygunluğu incelenmiştir. Bulgular-Analiz sonuçlarına göre arazinin afetselliği, arazi büyüklüğü ve yerleşim yerine uzaklık kriterleri en önemli üç kriter olarak tespit edilmiştir. Ayrıca, duyarlılık analizi ile de modelin uygunluğu ortaya konmuştur. Sonuç-Çalışmada elde edilen sonuçların karar vericilerin beklentileri ile örtüştüğü ve kararlarını desteklediği görülmektedir. Sonuçlar, gelecekte çalışmalarda bulanık yöntemler kullanılarak elde edilecek sonuçlar ile karşılaştırılabilir.Anahtar Kelimeler: Afet lojistiği, depo yer seçimi, çok kriterli karar verme teknikleri.

“…To solve the model, a cellular stochastic diffusion search-based intelligent algorithm was introduced. Hong and Xiaohua (2011) established a multi-objective location selection model based on AHP theory. The interrupt delay constraint was applied on the basis of considering the environment, economy and technical factor, the time minimisation objective was priority to cost minimisation objective.…”

Abstract:In post-disaster relief, competitive emergency service providers place their stations quickly for timely rescue activities. To shorten the rescue time of the emergency services and ensure the profit of emergency service providers, an extended game model is formulated to solve the problem based on the classical Hotelling model. In the new model, logistics cost is paid by service providers who can obtain honour profit through providing service for the victims. The victims endure waiting times that consist of periods of response time and travelling time. The waiting times affect the victims' decisions and affect the equilibrium prices and profits. Numerical analysis implies that service providers obtain the highest profits on their equilibrium price when their locations are decided. Furthermore, locating both players near the ends of the disaster-affected line city is beneficial to increase the gross profits.

“…Heaslip et al (2012) proposed a system analysis and design technique to explain how a more effective coordination of humanitarian operations by military and civilian organizations involved in disaster relief can be achieved across the range of humanitarian aid lifecycle phases. Finally, a study prepared by Hong and Xiaohua (2011) can be categorized in both groups of papers. They proposed a multi-objective location selection model which is based on AHP theory.…”

Urgent response is vitally important after unpredictable disasters and it is highly dependent to the location of the emergency centers. Considering this importance degree, in this study, a location selection methodology for emergency logistics centers (ELCs) is proposed. There are various influencing factors or criteria to choose the most convenient locations for ELCs. However, we focused on some of the most important and prior criteria to obtain a more feasible approach and less calculation intensity. The main point is ranking and weighting the convenient locations or cities for constructing an ELC in a region or country. The alternative locations are chosen through the mostly natural disaster-prone cities. Decision criteria are determined according to the expert opinions. Decision Making Trial and Evaluation Laboratory (DEMATEL) and Analytic Network Process (ANP) methods are integrated to determine the convenient locations considering the relations between criteria and alternative locations. Afterwards, a real life application of the proposed methodology is realized for the Turkey case. Finally, results are examined and analyzed in terms of their sensitivity on the criteria weight changes.
