Supplier selection is one of the strategic decisions for businesses. Today, competitive conditions of businesses are getting harder day by day at both national and international levels. On the other hand, in the market conditions where intense competition is experienced, businesses desire to determine the right suppliers to work with, to plan their activities in the long term and gain an advantage. Because the selected supplier is one of the most important factors affecting the long-term success of the business. In this study, the supplier selection problem of a company that operates in the Machinery Manufacturing Industry Sector in Istanbul has been solved with the Fuzzy Soft Sets Theory. Literature is reviewed for supplier selection and commonly used price, quality, speed (delivery) and flexibility criteria are used. Six suppliers evaluated by fuzzy flexible sets theory are listed as T6,T2,T4,T5,T1 and T3.

TEDARİKÇİ SEÇİMİNDE BULANIK ESNEK KÜMELER TEORİSİ

Öz

Tedarikçi seçimi, işletmeler için hayati önem taşıyan stratejik kararlardan bir tanesidir. Günümüzde işletmelerin rekabet koşulları ise hem ulusal hem uluslararası düzeyde gün geçtikçe zorlaşmaktadır. Yoğun rekabetin yaşandığı piyasa koşullarında işletmeler ise beraber çalışacakları doğru tedarikçileri belirleyerek, faaliyetlerini uzun dönemli planlayıp avantaj yakalamayı arzulamaktadır. Çünkü seçilen tedarikçi işletmenin uzun dönemli başarısını etkileyen önemli unsurların başında gelmektedir. Bu çalışmada İstanbul’ da Makine İmalat Sanayi’nde faaliyetlerini sürdüren bir firmanın tedarikçi seçim problemi Bulanık Esnek Kümeler Teorisi ile çözüme ulaştırılmıştır. Tedarikçi seçimi için literatür incelenmiş ve yaygın olarak kullanılan fiyat, kalite, teslimat ve esneklik kriterlerinden faydalanılmıştır. Bulanık esnek kümeler teorisi ile değerlendirilen 6 tedarikçi T6, T2,T4,T5,T1 ve T3 şeklinde sıralanmıştır.
