Bu çalışma, otomatik depolama ve geri-alma sistemlerinde kullanılan depolama
ve geri-alma makinesinin, hiçbir işlem gerçekleştirmiyorken (boştayken)
konumlandırıldığı bekleme noktasını optimize etmek için bir yaklaşım
sunmaktadır. Çalışma kapsamında, depolama ve geri-alma makinesinin sadece geri-alma
işlemini gerçekleştirdiği bir süreç dikkate alınarak, makinenin depodaki mevcut
ürün gruplarının ağırlık merkezlerine olan toplam uzaklığını minimize etmek
için bir matematiksel programlama modeli önerilmektedir. Depodaki ürün
yerleşimlerinde anlamlı farklılıkların oluştuğu belirli zamanlarda, depolama ve
geri-alma makinesi bekleme noktasının güncellenmesiyle de dinamik bir şekilde makine
pozisyonunun optimize edilmesi amaçlanmaktadır. Atanmış depolama politikası
altında ürünlerin depolandığı, tek koridora sahip örnek bir depo üzerinde, depolama
ve geri-alma makinesi bekleme noktası dinamik olarak optimize edilerek, önerilen
yaklaşımın çalışması örnek bir problem ile gösterilmektedir.

Storage and Retrieval Machine Dwell Point Optimization: Dedicated Storage Policy Case

Öz

This study presents an approach to optimize
the dwell point where the storage and retrieval machine in automatic storage
and retrieval systems is positioned when it does not perform any
operations (when it is idle). A mathematical programming
model is proposed to minimize the total distance of the storage and retrieval
machine to the centers of gravity of the stored product groups in the warehouse
in which only the retrieval process is taken into consideration. The
aim of the study is to optimize the machine position
dynamically by updating the dwell point of the storage and retrieval machine at certain times when
significant differences occur in the product locations in the warehouse. The proposed approach is illustrated using a case study defined
for a warehouse with
single corridor where the products are stored under the dedicated storage
policy by dynamically optimizing the dwell point of the storage and retrieval machine in an example problem.
