Özet:

 In a competitive environment, businesses want to control costs to maintain profitability. Working with the right supplier helps improve the quality of the enterprises products and services and keeps costs at the most appropriate level. Since there are multiple criteria in supplier selection, choosing the right supplier can be a complex problem. The preference criteria and the number of alternative suppliers can be challenging for decision-makers, and the rational decision-making process can be extended. This study aims to select the most suitable supplier for the raw leather material supply of a company manufacturing office chairs in the Organized Industrial Zone in Türkiye. AHP, TOPSIS, and WASPAS methods, which are different multi-criteria decision-making techniques, were used to solve this problem, and the results were compared. The managers opinions of the companys production, purchasing, and quality control units were consulted to determine the criteria required for the use of the methods and to evaluate these criteria. As a result of the literature and expert opinions, four main criteria and eight sub-criteria were formed. The main criterion was cost, followed by quality, delivery, and support. Suppliers were evaluated using all three techniques and ranked for the company.

 Rekabetçi bir ortamda işletmeler kârlılıklarını korumak için maliyetlerini kontrol etmek istemektedir. Doğru tedarikçi ile çalışmak, işletmenin ürün ve hizmetlerinin kalitesini artırmaya yardımcı olur ve maliyetleri en uygun seviyede tutar. Tedarikçi seçiminde birden fazla kriter söz konusu olduğu için doğru tedarikçiyi seçmek karmaşık bir problem olabilir. Tercih kriterleri ve alternatif tedarikçi sayısı karar vericiler için zorlayıcı olabilmekte ve rasyonel karar verme süreci uzayabilmektedir. Bu çalışma, Türkiyede Organize Sanayi Bölgesinde ofis koltuğu üreten bir firmanın ham deri malzeme tedariği için en uygun tedarikçiyi seçmeyi amaçlamaktadır. Bu problemi çözmek için farklı çok kriterli karar verme tekniklerinden AHP, TOPSIS ve WASPAS yöntemleri kullanılmış ve sonuçlar karşılaştırılmıştır. Yöntemlerin kullanımı için gerekli kriterlerin belirlenmesi ve bu kriterlerin değerlendirilmesi için firmanın üretim, satın alma ve kalite kontrol birimlerinin yöneticilerinin görüşlerine başvurulmuştur. Literatür ve uzman görüşleri sonucunda dört ana kriter ve sekiz alt kriter oluşturulmuştur. Ana kriter maliyet olurken, bunu kalite, teslimat ve destek takip etmiştir. Tedarikçiler her üç teknik kullanılarak değerlendirilmiş ve firma için sıralanmıştır.
