BULANIK TOPSIS VE BULANIK VIKOR YÖNTEMLERİ İLE EN UYGUN TEDARİKÇİ SEÇİMİ ÜZERİNE BİR UYGULAMA

Abstract

Günümüzün her geçen gün artmaya devam eden rekabet durumunda işletmelerin sürdürülebilir bir şekilde faaliyetlerine devam edebilmeleri için belirli stratejilere sahip olmalıdır. Bu stratejilerin başında da hiç kuşkusuz tedarikçiler ile olan stratejik ilişkiler yer almaktadır. Tedarikçiler ile yaşanabilecek herhangi bir problem işletmenin üretiminde ciddi zorluklara sebep olacaktır. Dolayısıyla işletmeler çalıştıkları tedarikçilerini en iyi şekilde belirlemeli ve uzun vadeli tedarikçi ilişkileri kurmalıdır. Bu çalışmada da gıda sektöründe faaliyet gösteren bir firmada tedarikçi seçimi üzerine bir çalışma yapılmıştır. Çalışmada satın alma departmanı personellerinin belirlediği beş farklı tedarikçi beş farklı kriter üzerinden değerlendirilmiştir. Değerlendirme için karar vericilerin daha esnek karar vermelerine imkan tanıyan bulanık TOPSIS yöntemi kullanılmıştır. Çok kriterli karar verme metotlarında bulanık TOPSIS metodu ile çözülen problemin sonuçları kıyaslama açısından bulanık VIKOR ile de çözülmüş ve sonuçlar kıyaslanmıştır.

AN APPLICATION ON THE MOST SUITABLE SUPPLIER SELECTION WITH FUZZY TOPSIS AND FUZZY VIKOR METHODS

Abstract

In today's increasing competitive situations companies need dynamic strategies to survive. Strategic relations with suppliers are undoubtedly at the top of these strategies. Any problems that may occur with the suppliers will cause serious difficulties during the production process of the company. Therefore, companies should determine their suppliers in the best way and establish long-term relationships. In this study, an application was conducted on supplier selection in a food company considering multiple criteria decision-making methodology. To achieve this aim, five different suppliers were determined by the purchasing department managers and they were evaluated concerning five different criteria. Fuzzy TOPSIS methodology was proposed to decide the best supplier. The problem is solved by fuzzy TOPSIS methodology. Finally, the same problem is also solved by using fuzzy VIKOR methodology to compare results.
