BİR İŞLETMENİN TEDARİKÇİ DEĞERLENDİRME VE SEÇİM PROBLEMİNİN ÇÖZÜMÜNDE AAS VE VIKOR YÖNTEMLERİNİN KULLANILMASI

Tedarikçi değerlendirme ve seçim problemi, işletmelerin ileriye dönük planlarının gerçekleştirilmesi açısından önem taşımaktadır. Tedarik zinciri yönetimindeki bu önemli sorunun üstesinden gelmek ise işletmelere önemli ölçüde rekabet avantajı sağlamaktadır. Çok kriterli bir karar verme problemi olan tedarikçi değerlendirme ve seçim problemi, günümüze kadar çok sayıda değişik yöntem ve yaklaşımların kullanılmasıyla çözülmeye çalışılmıştır. Bu çalışmanın amacı, VIKOR yöntemi kullanımı ile, makine imalatı gerçekleştiren bir işletmenin 14 tedarikçisi arasında bir değerlendirme ve sıralama gerçekleştirmektir. VIKOR yönteminin çözümünde önemli bir rol oynayan değerlendirme kriterlerinin ağırlıklandırılmasında, kriterlerin karşılıklı etkileşim içermesinden dolayı Analitik Ağ Süreci (AAS) yönteminden yararlanılmıştır. Uzlaşık çözümün elde edilmesinde dikkate alınan maksimum grup faydasının farklı değerleri için ayrı ayrı VIKOR çözümleri elde edilmiş ve sonuçlar yorumlanmıştır.

USAGE OF ANP AND VIKOR METHODS FOR SUPPLIER ASSESSMENT AND SELECTION PROBLEM OF A COMPANY

Supplier assessment and selection problem is an important milestone to perform business plan for a company. Therefore, to solve this important problem in supply chain management brings competitiveness to the company. Supplier assessment and selection problem based on multi criteria decision making problem is tried to solve by numerous different method and approaches until today. The aim of this study is to order and evaluate 14 suppliers of a machine manufacturer company by using VIKOR method. Analytic Network Process (ANP) method was used due to the interactions among criteria which has an important role to weight evaluation criteria in VIKOR method. VIKOR solutions are obtained for the different values of the maximum group utility which has taken into consideration to have a compromise solution, and results are interpreted.
