Dental supplier selection is a process that allows companies to choose their suppliers correctly in the light of evaluations. Choosing the right dental suppliers is an important factor both for the efficiency of dental treatment and handling an impressive supply chain. Dental supplier selection is a multi-criterion group decision-making (MCDM) problem that contains many different criterion about the decision-makers generally ambiguous information. TOPSIS method integrated intuitionistic fuzzy set is used in this study. Real-life problems include many unpredictability and defects. Experts are involved in assigning the weights of the criterion in this study. Linear programming (LP) methodology has applied for the ranking of these weights of criterion. Then, the LP methodology is carried out and it was ensured that the appropriate orthodontic bracket suppliers were selected. This is a specific multi-criterion decision making problem. The study was followed together with the sensitivity analyses of the results. At the end of the study, it is foreseen that with the right selection of suppliers, The competitive power of companies in the market and end user satisfaction will increase.

TOPSİS YÖNTEMİ İLE ORTODONTİK TEDARİKÇİ SEÇİMİ

Öz

Ortodontik Tedarikçi seçimi, firmaların ve şirketlerin tedarikçilerini değerlendirmeler ışığında daha doğru ve daha isabetli seçmelerini sağlayan bir süreçtir. Günümüzde Uygun Ortodontik sarf malzemesi tedarikçilerini seçmek, hem diş tedavisinin verimliliği hem de etkileyici bir tedarik zincirinin ele alınması için önemli bir faktördür. Ortodontik Tedarikçi seçimi, karar vericiler için genellikle birçok farklı kriter içeren çok kriterli grup karar verme (ÇKKV) problem olarak ele alınmaktadır. Bu çalışmada ÇKKV yöntemlerinde olan TOPSIS yöntemi ile bütünleştirilmiş sezgisel bulanık küme (BSBK) kullanılmıştır. Gerçek hayat problemleri birçok öngörülemezliği, karmaşıklığı ve kusuru içermektedir. Gerçekleştirilen çalışmada kriterin ağırlıklarının belirlenmesinde uzman görüşlerine yer verilmiştir. Daha sonra bu kriter ağırlıklarının sıralanması için ayrıca doğrusal programlama (DP) metodolojisi uygulanmış ve bu kapsamda uygun ortodontik braket tedarikçilerinin seçilmesi sağlanmıştır. Ele alınan konu, belirli birçok kriterli karar verme problemidir. Çalışma, sonuçları duyarlılık analizleri ile incelenmiştir. Makalenin sonunda, doğru Ortodontik Tedarikçi seçimi ile piyasada var olan şirket ve firmaların pazardaki rekabet gücünün ve son kullanıcı memnuniyetinin artacağı öngörülmektedir.
