Tedarik Zinciri Yönetiminde Dağıtım Ağlarının Tasarımı ve Optimizasyonu: Malzeme İhtiyaç Kısıtı Altında Stratejik Bir Üretim-Dağıtım Modeli

Bir tedarik zinciri; tedarikçiler, imalatçılar, dağıtıcılar, toptancılar, perakendeciler gibi çeşitli iş aktörlerinden oluşan bir ağda, hammadde temininden ürünlerin son tüketicilere dağıtım ve pazarlanmasına kadarki tüm iş süreçlerinin birlikte uyum içinde hareketini sağlamak üzere, malların ve bilginin akışını yöneten bütünleşik bir sistem olarak tanımlanabilir. Bu iş ağının öğelerinin, sayılarının ve yerlerinin tespiti, birbirleri arasındaki fiziksel akışın miktarının belirlenmesi gibi alt problemleri içeren ağ tasarımı problemi tedarik zinciri yönetimi içinde stratejik bir öneme sahiptir. Bu çalışmada, tedarik zinciri yönetiminde dağıtım ağlarının tasarımı ve optimizasyonu problemi ele alınmıştır. Malzeme ihtiyaç kısıtı altında stratejik üretim-dağıtım problemi için çok aşamalı karma tamsayılı bir model geliştirilmişti!.

A supply chain can be defined as an integrated system, which manages information and physical distribution, in order to synchronize a series of business processes from the supply of raw materials and components to delivery of finished products through end customers in a network that includes various business actors such as suppliers, manufacturers, distributors, and retailers. Network design problem, that includes sub problems such as assigning the numbers and the locations of entities of this business network and determining the amount of physical distribution among these entities, has a strategic role in supply chain management. In this study, design and optimization problem of distribution networks in supply chain management is considered. A multi echelon mixed integer model for the production-distribution model under material requirements constraints is developed.
