Abstract

Talebe Dayalı Malzeme İhtiyaç Planlaması (TDMİP), geleneksel Malzeme İhtiyaç Planlamasına (MİP) bir alternatif olarak ortaya çıkan, talep odaklı ve esnek bir planlama yaklaşımıdır. TDMİP, envanter seviyelerini etkin bir şekilde yöneterek dinamik ve değişken taleplere hızlı bir şekilde tepki vermeyi hedeflemektedir. Bu karakteristikleri sayesinde TDMİP, günümüz dinamik iş ortamında etkin bir malzeme yönetimi ve ihtiyaç planlaması yöntemi olarak dikkat çekmektedir. Bu çalışmada, TDMİP yaklaşımının, bağlantı elemanları satışı yapan bir firmada uygulanması ile ortaya çıkan performansı, geleneksel MİP ile karşılaştırılmıştır. Tedarik sürelerinin stokastik yapıda olması nedeniyle, karşılaştırmalar benzetim modellemesi kullanılarak gerçekleştirilmiştir. Karşılaştırmaların eşit koşullarda olması açısından hem TDMİP hem de MİP için parametrelerin en iyi değerleri benzetim optimizasyonu ile belirlenmiş ve karşılaştırmalarda bu parametre değerleri kullanılmıştır. Gerçek talep verileri kullanılarak yapılan karşılaştırmalarda TDMİP’in MİP’e göre hizmet düzeyinde %4.1 artış, toplam envanter maliyetinde %35.1 azalma ve ortalama stok seviyesinde ise % 64.8 azalma sağladığı görülmüştür.

Keywords
