Talebe dayalı malzeme ihtiyaç planlamaya dönüşüm süreci: Bir hazır giyim firmasında uygulama

Belirsizliğin arttığı bugünün çalışma ortamında perakendecilerin doğru stokları doğru yerde ve doğru miktarda tutmaları önem kazanmıştır. Doğrusal yöntemlerin değişkenliğe dayanıksızlığı ve tahmin hataları stok yönetimini zorlaştırmaktadır. Bu çalışmada Hazır Giyim firmalarına talebe dayalı çekme tipi üretim yönetimine dönüşüm için yol haritası önerilmektedir. Talebe Dayalı Malzeme İhtiyaç Planlama (Demand Driven Material Requirement Planning-DDMRP) uygulamasıyla merkez depodan mağazalara gün aşırı döngüsel sefer (milk-run) tarzında tamamlama servisi verilmiştir. Aynı zamanda fabrikanın üretim iş emirleri merkez depodaki DDMRP uygulamasına göre düzenlenmiştir Geleneksel perakende dağıtımı satış tahmini, min-maks stok seviyelerine göre otomatik tamamlama ve birim maliyet düşürme amacıyla satınalma-üretim-sevk için parti büyütme esaslıdır. Gelenekselin aksine ürün aileleri bazında yıllık eğilim dışında satış tahmini ve optimizasyon kullanılmadan dinamik stok yönetimi uygulanarak bir yıl içinde üretimdeki akış süresi %33 azaltılmış, yarı mamul stoklar %37 düşürülmüş, mamul stoklarda %17 azalma ve satışlarda %20 artış elde edilmiştir.

In today's VUCA environment availability is the major issue for Retailers. The fragility of linear methods under volatility and remarkable forecast errors are major challenges. The traditional method relies on sales forecasting and larger batches to reduce unit cost and min-max for replenishment. This study proposes a roadmap for the transformation to demand-driven pull-type production management for retailers. The retailer issued work orders and organized frequent deliveries by Demand Driven Material Requirement Planning (DDMRP). During the same year, flow time was reduced by 33%, WIP dropped by 37%, finished goods inventory dropped by 17% and sales increased by 20%.
