Simulation-Based Evaluation of Order Picking Systems with Integrated Inventory Replenishment

Öz

Order picking activities play a critical role in supply chain management by providing components for assembly operations in production systems and ensuring the fulfillment of customer demands in distribution systems. Trends in customer behavior indicate a shift from fewer, larger orders to a greater number of smaller orders, while order lead times continue to decrease. To remain competitive, companies must implement efficient order picking systems that can adapt to changing conditions. This study examines the distribution warehouse of a fastener manufacturing company, with the aim of improving order picking performance. In addition to addressing key factors such as storage assignment and routing methods, the study also explores the often-overlooked inventory replenishment process within storage areas. A simulation model was developed to account for probabilistic demand and order picking frequency. Alternative combinations of storage assignment and routing strategies for the order picking process were evaluated under the (s, S) inventory policy. The experimental results identify the optimal combination of operating policies that minimizes order picking time.

Entegre Envanter Yenilemeli Sipariş Toplama Sistemlerinin Simülasyon Tabanlı Değerlendirilmesi

Öz

Sipariş toplama faaliyetleri, üretim sistemlerinde montaj operasyonları için bileşenler sağlarken, dağıtım sistemlerinde müşteri taleplerinin karşılanmasını güvence altına alarak tedarik zinciri yönetiminde kritik bir rol oynar. Müşteri davranışlarındaki eğilimler, daha az sayıda büyük siparişlerden daha fazla sayıda küçük siparişlere doğru bir değişime işaret ederken, sipariş teslim süreleri de azalmaya devam etmektedir. Rekabetçi kalabilmek için şirketler, değişen koşullara uyum sağlayabilen verimli sipariş toplama sistemleri uygulamalıdır. Bu çalışma, bağlantı elemanları üreten bir şirketin dağıtım deposunu incelemekte olup, sipariş toplama performansını iyileştirmeyi amaçlamaktadır. Depolama ataması ve yönlendirme yöntemleri gibi önemli faktörlerin yanı sıra, depolama alanlarındaki sıklıkla göz ardı edilen envanter yenileme süreci de çalışmada ele alınmaktadır. Olasılıksal talep ve sipariş toplama sıklığı dikkate alınarak bir simülasyon modeli geliştirilmiştir. Sipariş toplama sürecindeki depolama atama ve yönlendirme stratejilerinin alternatif kombinasyonları, (s, S) envanter politikası altında değerlendirilmiştir. Deneysel sonuçlar, sipariş toplama süresini minimize eden en uygun işletim politikası kombinasyonunu belirlemektedir.
