Bulanık Uzman Sistem Yaklaşımı ile Yeşil Tedarikçi Değerlendirmesi

Abstract

Günümüzde küresel ölçekte artan kirlilik ve sınırlı hammadde kaynakları gibi nedenler, yeşil tedarik zinciri yönetimine (YTZY) olan ilgiyi artırmaktadır. YTZY, bir ürünün üretim sürecinin en başından başlayarak, üretiminin tamamlanması, ürünün müşteriye teslim edilmesi ve kullanım ömrü sonunda ürünün geri dönüştürülmesine kadar olan süreçleri kapsamaktadır. Temel amacı, tüm bu süreçlerde çevreye verilen zararları ortadan kaldırmak veya en aza indirmektir. Bu hedefe ulaşmak için üretim sürecinin en önemli bileşenlerinden biri olan tedarikçilerin yeşil tedarikçi olma açısından değerlendirilmesi büyük önem taşımaktadır. Bu çalışmada, yeşil üretim teknolojisi, çevre yönetim sistemi, kirlilik kontrolü, ürün maliyeti, kalite ve teslim süresi kriterlerine dayalı olarak yeşil tedarikçilerin değerlendirilmesi için bulanık bir uzman sistem modeli geliştirilmiştir. Geliştirilen modelin performansını ölçmek için Ortalama Karesel Hata (MSE) ve belirlilik katsayısı (R2) hesaplanmıştır. Hesaplanan bu değerler, geliştirilen modelin yeşil tedarikçi değerlendirme performansının oldukça yüksek olduğunu göstermektedir.

Green Supplier Assessment with Fuzzy Expert System Approach

Abstract

Today, reasons such as increasing pollution on a global extent and limited raw material resources are increasing the interest in green supply chain management (GSCM). GSCM includes the processes starting from the very beginning of the production process of a product, completing the production, delivering the product to the customer, and recycling the product at the end of its useful life. Its main purpose is to eliminate or minimize the damages caused to the environment in all of these processes. In order to achieve this goal, it has great importance to assess the suppliers, which are one of the most important components of the production process, in terms of becoming a green supplier. In this study, a fuzzy expert system model has been developed to assess the green suppliers based on green production technology, environmental management system, pollution control, product cost, quality, and lead time criteria. Mean Square Error (MSE) and coefficient of determination (R2) have been calculated to measure the performance of the developed model. These calculated values show that the green supplier assessment performance of the developed model is quite high.
