SÜRDÜRÜLEBİLİR TEDARİKÇİ SEÇİMİ İÇİN BÜTÜNLEŞİK FERMATEAN BULANIK SWARA-WASPAS YÖNTEMLERİ

Öz

Günümüz iş dünyasında sürdürülebilir tedarikçi seçimi, yalnızca etik sorumluluklar nedeniyle değil, aynı zamanda rekabet avantajını artırmak ve uzun vadeli riskleri yönetmek açısından da stratejik bir önem kazanmıştır. Tüketiciler, yatırımcılar ve düzenleyici kurumlar gibi paydaşlar, şirketlerin tedarik zincirlerinin tamamında sürdürülebilirlik ilkelerini benimsemelerini giderek daha fazla beklemektedir. Bu nedenle, geleneksel ekonomik göstergelere ek olarak çevresel, sosyal ve yönetişim (ÇSY) kriterlerinin entegre edilmesi artık bir gereklilik hâline gelmiştir. Bu çalışma, büyük ölçekli bir perakende kuruluşunun tedarikçi değerlendirme sürecine odaklanmakta ve sürdürülebilirlik odaklı karar verme kriterlerini içermektedir. Kapsamlı bir literatür taramasına dayanarak mevcut değerlendirme kriterleri gözden geçirilmiş ve ÇSY boyutlarını içerecek şekilde genişletilerek ekonomik, çevresel, sosyal ve yönetişim olmak üzere dört ana kategori altında 18 alt kriterden oluşan bütüncül bir çerçeve oluşturulmuştur. Bu kriterlerin önem düzeylerini belirlemek için Fermatean Bulanık SWARA yöntemi uygulanmış, tedarikçi alternatifleri ise Fermatean Bulanık WASPAS tekniğiyle önceliklendirilmiştir. Elde edilen bulgular, sürdürülebilir tedarik uygulamalarını geliştirmek isteyen uygulayıcılara yönelik uygulanabilir öngörüler sunmaktadır.

INTEGRATED FERMATEAN FUZZY SWARA-WASPAS METHODS FOR SUSTAINABLE SUPPLIER SELECTION

Öz

In today's business landscape, sustainable supplier selection has gained strategic significance, not only due to ethical responsibilities but also as a key factor in enhancing competitive advantage and managing long-term risks. Stakeholders such as consumers, investors, and regulatory agencies increasingly expect companies to adopt sustainability principles throughout their supply chains. Consequently, integrating environmental, social, and governance (ESG) criteria alongside traditional economic indicators has become essential. This study focuses on a large-scale retail organization’s supplier evaluation process by incorporating sustainability-oriented decision-making criteria. Building on a comprehensive literature review, existing evaluation criteria were revised and expanded to include ESG dimensions, forming a holistic framework of 18 sub-criteria across four primary categories: economic, environmental, social, and governance. To determine the importance of these criteria, the Fermatean Fuzzy SWARA method was applied, and supplier alternatives were prioritized using the Fermatean Fuzzy WASPAS technique. The findings provide actionable insights for practitioners seeking to enhance sustainable procurement practices.
