Tedarik zinciri ağ tasarımına bulanık ulaştırma modeli yaklaşımı

Yeni is çevresindeki belirsizlikler dikkate alındığında; isletmelerin, maliyetlerde, taleplerde ve kapasitelerde meydana gelebilecek belirsizlikleri etkin yönetmesi gerekmektedir. Karar alma süreçlerindeki bu durum karar vericileri sübjektiflik altında karar almaya mecbur bırakmıştır. Bu çalışmada tedarik zincirlerinde işletme problemlerinden ulaştırma problemi ele alınarak bu problemde meydana gelebilecek belirsizlikler bulanık doğrusal programlama yöntemi ile çözülmeye çalışılmıstır. Ele alınan problemde sadece amaç fonksiyon katsayılarının bulanık olması (maliyetlerin bulanıklığı), sadece sağ taraf sabitlerinin bulanık olması (taleplerin ve kapasitelerin) ve hem amaç fonksiyonun hem de sağ taraf sabitlerinin bulanık olması sonucunda elde edilen modeller incelenmiştir. Her bir model ile hangi arz merkezinden hangi talep merkezine ne kadar maliyetle tasıma olduğu tespit edilmiştir.

Fuzzy transport model approach to supply chain network desing

Companies should manage indefinities at costs, demand an capacity effectively, if ambiguities in new business environment are pointed out. This situation on decision process forces decision makers to make desicion subjectively. For this reason, transport model that is one of the business problem in supply chains, is solved by fuzzy linear programming model. Three different models are examined, such as, only objective function has fuzzy coefficients (fuzzy costs), only right hand constants are fuzzy (fuzzy demand and capacities), finally both of them fuzzy. Transportation from which supply point to which demand point and what it costs are determined by each model.
