Öz

Supplier loyalty within the sectors affects the competitiveness of the enterprises as well as the material elements. The basic aim of the research is to evaluate the supplier loyalty’s existing in different sectors. In this research, DEMATEL and MAUT methods were used to evaluate the supplier loyalty's within the sectors. For that purpose, firstly, factors that affecting the supplier loyalty’s were specified via expert opinions and research of literature. After specifying the factors, the factors that affecting the supplier loyalty’s were prioritized with DEMATEL method. Following the prioritized of factors, suppliers loyalty’s to the sectors was evaluated by utilizing the MAUT method. Lastly, changes that may occur in the results of the research were examined by performing scenario analysis.

Bütünleştirilmiş DEMATEL-MAUT Yöntemiyle Tedarikçi Bağlılığının Sektörel Açıdan Değerlendirilmesi

Öz

Sektörlerin bünyesinde bulunan tedarikçi bağlılığı maddi unsurların yanı sıra işletmelerin rekabet güçlerini de etkilemektedir. Bu araştırmanın temel amacı, farklı sektörlerin bünyesinde var olan tedarikçi bağlılığının değerlendirilmesidir. Bu araştırmada sektörlerin bünyesinde yer alan tedarikçi bağlılığının değerlendirilmesi için DEMATEL ve MAUT yöntemleri kullanılmıştır. Bu amaçla ilk olarak uzman görüşleri ve ilgili literatür araştırması doğrultusunda tedarikçi bağlılığını etkileyen faktörler belirlenmiştir. Faktörlerin belirlenmesinin ardından tedarikçi bağlılığını etkileyen faktörler DEMATEL yöntemiyle önceliklendirilmiştir. Faktör önceliklerinin belirlenmesinin ardından MAUT yöntemiyle sektörlerin tedarikçi bağlılığı değerlendirilmiştir. Son olarak senaryo analizi gerçekleştirilerek araştırmanın sonuçlarında meydana gelebilecek değişimler incelenmiştir. Gerçekleştirilen analizin sonuçları, “Maliyetler”in tedarikçi bağlılığında en önemli faktör olduğunu göstermiştir. Ayrıca, tekstil sektörü araştırmadaki sektörler içerisinde tedarikçi bağlılığı açısından en yüksek sektör olarak belirlenmiştir.
