Abstract
Son yıllarda, tedarikçi seçimi dikkatlice üzerinde çalışılmakta olan bir problem olmaktadır. Günümüzün rekabet ortamında, lojistik faaliyetleri içerisinde depolamanın önemi gittikçe artmaktadır. Depoculuk faaliyetlerinin daha kapsamlı bir hale gelmesiyle, üreticiler için üçüncü parti lojistik servis sağlayıcıları bir ihtiyaç haline gelmektedir. Bu çalışma da farklı tedarikçi değerlendirme yöntemleri incelenerek, aynı sektörlerde hizmet veren üç lojistik firmasını ele alınmıştır. Bu tez, çoklu kriterli karar verme modeli üçüncü parti hizmet sağlayıcılarının alternatiflerini oluşturmaktadır. Çok kriterli karar verme problemi olarak değerlendirilebilecek bu problemin çözümünde Analitik Hiyerarşi Süreci (AHS) ve VIKOR yöntemleri kullanılmıştır. Bu çalışmanın amacı en verimli üçüncü parti depo firmasını seçmektir. Sürecin değerlendirilmesi detayları ile gösterilmiştir. Veriler, Türkiye'de tanınmış lojistik şirketlerinden alınmıştır. Altı ana kriter uygulama için tespit edilmiştir. Bunlar 'pazar', 'kalite', 'operasyonel', 'yapı', 'hizmet' ve 'sosyal sorumluluk ya da yeşil projeler' dir. Görünüşe göre, depo seçimi nicel ve nitel faktörleri de içeren çoklu kriterli bir sorundur. Çalışmada, çıktılar karşılaştırıldı ve tartışıldı.
