Abstract

One of the main issues to be addressed in supply chain management is the supplier selection which aims to deliver the right product at the right time, in the right quality, in the right place, and at the most appropriate cost. Enterprises that select the right suppliers and determine the appropriate order distribution are more competitive in terms of competitiveness than others because the performance of suppliers, such as cost, quality, on-time delivery, and flexibility, affects direct production in achieving their goals. Legal regulations and increasing awareness among people about the protection of the environment has forced companies to attach importance to Green Supply Chain Management (GSCM) practices which have led to the concept of Green Supplier Selection (GSS) in supplier selection. GSS is a Multi- Criteria Decision Making (MCDM) problem involving qualitative and quantitative conflicting factors. Many individual and integrated approaches for GSS have been proposed and continue to be proposed. Several approaches have been proposed to convert multi-objective linear programming problems, which involve multiple conflicting objectives, to a single-objective linear programming problem. In this study, a new Multi-Objective Linear Programming (MOLP) model was for GSS. Fuzzy Multi-Objective Linear Programming (FMOLP) approaches, which are frequently used in the literature, are discussed in order to convert the developed MOLP to the single-objective linear programming problem. A comparison of solution approaches has been made in order to choose the best supplier and to make order allocation. In addition, the Analytical Hierarchy Process (AHP) method was used to determine the weights of the determined criteria in order to measure the influence of decision- makers' opinions on the model. The feasibility and comparability of the proposed model and the FMOLP approaches are illustrated with an example.

Özet

Doğru ürünü, doğru zamanda, doğru kalitede, doğru yerde üreterek en uygun maliyetle müşterilere ulaştırmayı amaçlayan tedarik zinciri yönetiminde ele alınması gereken başlıca konulardan birisi tedarikçi seçimidir. İşletmelerin hedeflerine ulaşmasında tedarikçilerin maliyet, kalite, zamanında teslimat ve esneklik gibi performansları doğrudan üretimi etkilemesi nedeniyle uygun tedarikçiyi seçen ve uygun sipariş dağıtımını belirleyen işletmeler, diğerlerine göre rekabet açısından daha avantajlı bir konuma gelmektedir. Yasal düzenlemeler ve çevrenin korunması konusunda insanlar arasında artan bilinç, işletmeleri Yeşil Tedarik Zinciri Yönetimi (YTZY) uygulamalarına önem vermeye zorlamış ve bu durum tedarikçi seçiminde Yeşil Tedarikçi Seçimi (YTS) kavramını ortaya çıkarmıştır. YTS nitel ve nicel çelişkili faktörleri içeren bir Çok Kriterli Karar Verme (ÇKKV) problemidir. YTS için birçok bireysel ve bütünleşik yaklaşım önerilmiş ve önerilmeye devam etmektedir. Birden fazla çelişkili amaçların yer aldığı çok-amaçlı doğrusal programlama problemlerini tek-amaçlı doğrusal programlama problemine dönüştürebilmek için çeşitli yaklaşımlar önerilmiştir. Bu çalışmada, öncelikle YTS için yeni bir Çok-Amaçlı Doğrusal Programlama (ÇADP) modeli oluşturulmuştur. Geliştirilen ÇADP’ni tek-amaçlı doğrusal programlama problemine dönüştürebilmek için literatürde sıklıkla kullanılan Bulanık Çok-Amaçlı Doğrusal Programlama (BÇADP) yaklaşımları ele alınmıştır. En iyi tedarikçiyi seçebilmek ve sipariş dağıtımını yapabilmek için çözüm yaklaşımlarının karşılaştırılması yapılmıştır. Ayrıca karar verici görüşlerinin model üzerindeki etkisini ölçebilmek amacıyla Analitik Hiyerarşi Prosesi (AHP) yöntemi ele alınan kriterlerin ağırlıklarını belirlemek için kullanılmıştır. Önerilen modelin ve BÇADP yaklaşımlarının uygulanabilirliği ve karşılaştırılması bir örnek üzerinde gösterilmiştir.
