ULUSLARARASI TEDARİKÇİ SEÇİM PROBLEMİNDE BULANIK DEMATEL YÖNTEMİNİN KULLANIMI

Öz

Tedarikçi seçimi ulusal pazarlarda olduğu gibi uluslararası pazarlarda da işletmeler açısından üzerinde önemle durulması gereken bir konudur. Çünkü günümüzde artık işletmeler değil tedarik zincirleri rekabet etmektedir. Böylece tedarik zincirlerinin en önemli öğelerinden olan tedarikçiler gün geçtikçe daha fazla önem kazanmaktadır. İşletmeler bu nedenle tedarik zinciri tasarımında doğru tedarikçiyle/lerle çalışmak mecburiyetindedir. Tedarikçi seçimi birbiriyle çelişen amaçların maksimizasyonunu gerektirdiğinden çok kriterli karar verme problemleri sınıfındadır. Bu çalışmada uluslararası piyasalarda faaliyet gösteren büyük ölçekli bir işletmenin tedarikçi seçim problemine Bulanık Dematel yöntemi ile çözüm aranmıştır. Karar kriterleri arasındaki etkileşimi dikkate aldığından çok kriterli karar verme yöntemlerinden Bulanık Dematel yöntemi seçilmiştir. Tedarikçi seçim problemlerinde hangi kriterlerin daha fazla ağırlığa sahip olduğunu tespit etmek bu çalışmanın ana amacını oluşturmaktadır. Altı karar kriteri baz alınarak yapılan çalışmada teknik yetenek, maliyet, teslimat performansı ve tedarikçi ilişkisi etkileyen; kalite ve ün ise etkilenen karar kriterleri olarak tespit edilmiştir.

USING FUZZY DEMATEL METHOD FOR INTERNATIONAL SUPPLIER SELECTION PROBLEM

Öz

The supplier selection is an issue that should be emphasized in the international markets as well as in the national markets. Because, nowadays, supply chains compete instead of enterprises. Thus, suppliers, which are one of the most important elements of supply chains, are gaining more importance day by day. Therefore businesses are obliged to work with the right supplier (s) in the supply chain design. Supplier selection is in the category of multi-criteria decision making problems because it requires maximization of conflicting goals. In this study, the supplier selection problem of a large - scale enterprise, which is operating in international markets, investigated by the Fuzzy Dematel method. As it takes into account the interaction between the decision criteria, the Fuzzy Dematel method was chosen as one of the multi-criteria decision making methods. The main purpose of this study is to determine which criteria have more weight in supplier selection problems. In the study based on six decision criteria; technical talent, cost, delivery performance and supplier relationship are influencing factors, quality and reputation criteria are determining as affected decision criteria.

Anahtar Kelimeler

• Supplier selection,Multi-criteria decision making
