Bulanık Ortamda VIKOR Kullanarak Hastane Yeri Seçimi için Grup Karar Verme

Öz

Amaç: Bu çalışmanın amacı, bulanık ortamda çok kriterli karar verme teknikleri kullanarak 10 kriter altında, bir sağlık işletmesi için en iyi hastane yerinin seçilmesidir. Bu çalışmanın diğer bir önemli amacı da, hastane işletmesinin Yönetim Kurulu üyelerinin ağırlıklarının karar verme sırasında dâhil edilmesidir.

Yöntem: Değerlendirmeler, özel bir sağlık işletmesi için en iyi hastane yerinin seçimi üzerine gerçekleştirilmiştir. Bu amaç için; grup karar verme kullanarak Yönetim Kurulu üyelerinin de yardımıyla bulanık VIKOR (VlseKriterijumska Optimizacija I Kompromisno Resenje) yöntemi kullanılmıştır. Yönetim Kurulunun tüm üyeleri, Yönetim Kurulundaki ağırlıklarına göre probleme dâhil edilmişlerdir. Bundan dolayı, hastane yeri seçim kararını verme amacında olan bu çalışmanın sonuçları daha objektif olmuştur.

Bulgular: Çalışmanın sonuçları, yeni bir hastane için en iyi yeri göstermiştir. Ayrıca, karşılaştırmalar için, hastane yerleri arasındaki farklar da bulanık sonuçlardan açıkça görülebilir. Bu çalışmayı ve önerilen yöntemi doğrulamak adına, diğer bir bulanık çok kriterli karar verme yöntemi de probleme uygulanmıştır. Tüm sonuçların tutarlılığı, hastane yeri seçimi için önerilen yöntemin uygulanabilirliğini, etkinliğini ve geçerliliğini göstermektedir.

Sonuç: Tüm sonuçların birlikte değerlendirilmesi, önerilen yöntemin hastane yeri seçimi için etkili olduğunu ve sağlık işletmelerinin diğer karar verme problemleri için de uygulanabileceğini göstermektedir.

Group Decision Making for Hospital Location Selection Using VIKOR under Fuzzy Environment

Öz

Aim: The purpose of this study is to select the best hospital location for a health institution under 10 criteria using multi criteria decision making techniques under fuzzy environment. Another important purpose of this study is to include weights of the members of the board of directors of the institution while making decisions. 

Method: Evaluations are done to select the best hospital location for a private health institution. To this aim, fuzzy VIKOR (VlseKriterijumska Optimizacija I Kompromisno Resenje) method is used with the help of members of the board of directors by using group decision making. All members of the board of directors are included in the problem according to the weights in the board of directors. Hence, the results of the study to make the decision of hospital location selection are more objective.

Findings: The results of this study demonstrate the best location for a new hospital. In addition, differences between the locations are clearly seen at the fuzzy results for comparisons. To validate the results of this study and the proposed method, another fuzzy multi criteria decision making method is applied to the problem. Consistency of all results shows applicability, effectiveness and validity of the proposed method for hospital location selection.

Conclusion: Evaluations of all results show that the proposed method is efficient for hospital location selection problem and can also be applicable for other decision making problems of health institutions.
