Supply chain management is
an emerging area that drawing increasing attention of academics and
practitioners for decades. In recent years, SCM's focal point has begun to
emerge as a sustainable flow management, in which economic, social and
environmental aspects such as energy consumption, carbon emissions are jointly
addressed. This study focused on formulating and solving a bi-objective
multi-period closed loop supply chain network design problem. The model
determines the production and distribution strategies, while minimizing two
objectives simultaneously; the total supply chain cost and the carbon emissions
generated by plants operating through different machinery types. While the
initial purchase cost of older and more outdated machinery is lower than newer ones,
older machinery emits greater amount of carbon per hour as opposed to newer
machinery while operating at even greater cost per hour. Besides, the number of
products produced in an hour is also higher in newer machinery. We adopted a
fuzzy weighted additive approach to solve the bi-objective optimization model.
The results confirm that investing in newer technologies in manufacturing comes
with great result for both economic and environmental causes, reducing the unit
cost and carbon emission per product throughout the manufacturing periods.

İKİ AMAÇLI FARKLI MAKİNE SEÇENEKLİ KAPALI DÖNGÜ TEDARİK ZİNCİRİ OPTİMİZASYONU: BULANIK ÇÖZÜM TEKNİĞİ UYGULAMASI

Tedarik zinciri yönetimi,
küreselleşme çağının başlangıcından beri akademisyenlerin ve uygulayıcıların
artan ilgisini çekmeye devam etmiştir. Son yıllarda, tedarik zinciri
yönetiminin odak noktası, enerji tüketimi, karbon emisyonları gibi ekonomik,
sosyal ve çevresel yönlerin ortaklaşa ele alındığı sürdürülebilir akış yönetimi
olmaya başlamıştır. Bu çalışmada, çok dönemli kapalı döngü tedarik zinciri ağ
tasarım probleminin optimizasyonu için iki amaçlı karmaşık tamsayılı doğrusal
programlama modelinin formüle edilmesi ve çözülmesi gerçekleştirilmiştir. Model,
farklı makine tiplerinde faaliyet gösteren tesislerin toplam operasyon maliyeti
ve toplam karbon emisyonları olmak üzere iki ayrı amacın minimizasyonunu
hedeflerken, üretim ve dağıtım stratejilerini belirlemekte ve yeni veya eski
tip makinelerin kullanımına da karar vermektedir. Daha eski ve güncel olmayan
makinelerin ilk satın alma maliyeti, yeni ve güncellenmiş makinelere göre daha
düşük olmasına rağmen, eski makineler, saat başına daha yüksek maliyetle
çalışırken yeni makinelere göre saat başına daha fazla karbon salmaktadır.
Ayrıca, bir saat içinde üretilen ürünlerin sayısı, yani üretkenlik, yeni
makinelerde daha üstündür. Bu iki amaçlı kapalı döngü tedarik zinciri modelinin
çözümü için bulanık ağırlıklandırma yaklaşımı kullanılmıştır. Sonuçlar, üretimde
yeni nesil teknolojilere yatırım yapılmasının hem ekonomik hem de çevresel amaçlara
ulaşmak için önemli olduğunu göstermektedir.
