Kısa Ömürlü Ürünlerin Tedarik Zincirinin Modellenmesi ve Simülasyon Çalışması

Bu çalışmada kısa ömürlü ürünlerin stok yönetimi seri bir tedarik zinciri üzerinde incelenmiştir. Müşteri, perakendeci ve üreticiden oluşan üç aşamalı tedarik yapısının stok seviyesi ve sipariş verme noktaları simülasyon yardımıyla modellenmiş ve en uygun parametreler simülasyon optimizasyonu yaklaşımı ile tespit edilmiştir. Stok yönetimi simülasyon çalışmalarında merkezi ve merkezi olmayan stok yönetimi incelenmiş, çıkan sonuçlar karşılaştırmalı tablolarla gösterilmiştir. Çalışmada toplam tedarik zinciri maliyetinin minimize edilmesi ve müşteri memnuniyet seviyesinin arttırılması performans ölçütleri olarak göz önüne alınmıştır.

Anahtar Kelimeler:

Kısa ömürlü ürünlerde stok yönetimi, Tedarik zinciri yönetimi, Stok yönetimi, Simülasyon

Supply Chain Modelling of Perishable Products and Simulation Study

In this study, inventory management of perishable products is studied in multi-stage supply chain setting. In a three stage supply chain setting which consists of customer, retailer and manufacturer, perishable inventory management is modeled and parameters of the model are determined with simulation optimization approach. A simulation program is used for modeling inventory management, centralized and decentralized inventory management is examined, and the results are presented on comparative tables. In study, minimization of total cost of supply chain and improving customer satisfaction level are considered as performance measures.

Keywords:
