This study will evaluate the sustainability performance of five leading insurance companies in Türkiye for 2021. Unlike other studies, this research employed sub-criteria and the three basic dimensions of sustainability. The criteria weights were determined using the Spherical Fuzzy AHP method, a novel approach in the literature. Thus, the importance of the basic dimensions of sustainability was determined. It was seen that environmental dimensions had the most impact, followed by social and economic dimensions, respectively. TOPSIS, CODAS and PIV methods were used to rank the companies. The results obtained with the three methods were combined with the Borda Counting method to get the final ranking. According to the results, the company with the highest sustainability performance was Euroko Insurance Company.

Küresel Bulanık AHP Tabanlı TOPSIS, CODAS ve PIV Yöntemleri ile Sigorta Şirketlerinin Sürdürülebilirlik Performansının Değerlendirilmesi

Öz

Bu çalışmanın amacı, Türkiye'deki önde gelen beş sigorta şirketinin 2021 yılına ait sürdürülebilirlik performansını değerlendirmektir. Sürdürülebilirliğin üç temel boyutu ile birlikte diğer çalışmalardan farklı olarak alt kriterler de kullanılmıştır. Kriter ağırlıkları, yine literatürde yeni bir yöntem olan Küresel Bulanık AHP yöntemi ile belirlenmiştir. Böylece sürdürülebilirliğin temel boyutlarının önemleri belirlenmiştir. Çevresel boyutların en fazla etkiye sahip olduğu, bunu sırasıyla sosyal ve ekonomik boyutların izlediği görülmüştür. Şirketlerin sıralanması için TOPSIS, CODAS ve PIV yöntemleri kullanılmıştır. Üç yöntemle elde edilen sonuçlar, Borda birleştirme yöntemiyle birleştirilerek nihai sıralama elde edilmiştir. Sonuçlar doğrultusunda, sürdürülebilirlik performansı en yüksek olan şirketin Euroko Sigorta Şirketi olduğu belirlenmiştir.
