ERROR DETECTION IN MANUAL ORDER PICKING OPERATIONS: WEIGHT CHECK POINT

Öz

In this study, a weight control system is proposed to detect erroneous picks caused by pickers in manual order picking operations. With this system, erroneous picking will be detected in the warehouse and errors will be corrected before shipment. The study was carried out in a logistics warehouse with 30% of total shipments consisting of mixed pallets, and the effect of missing shipments for 1 year before and after the proposed weight checkpoint on customer complaints was examined. In the study, it was determined that 13,762 pallets were outside the specified tolerance range at the weight checkpoint. It was ensured that the errors in the pallets were eliminated by performing the necessary controls by the pickers. With the proposed system, 92.9% reduction in the number of parcels sent to the customer incorrectly and reduction of 82.4% in customer complaints was achieved. It has been observed that the weight checkpoint in manual order picking has made significant contributions to reducing error rates and customer complaints.

MANUEL SİPARİŞ TOPLAMA OPERASYONLARINDA HATA TESPİT UYGULAMASI: AĞIRLIK KONTROL NOKTASI

Öz

Bu çalışmada, manuel sipariş toplama operasyonlarında toplayıcı personel kaynaklı hatalı toplamaların tespit edilmesi için bir ağırlık kontrol sistemi önerilmektedir. Bu sistem ile hatalı toplamalar depo içerisinde tespit edilecek ve sevkiyattan önce hataların düzeltilmesi sağlanacaktır. Çalışma, toplam sevkiyatların %30’u karma paletlerden oluşan bir lojistik depoda gerçekleştirilmiş olup, önerilen ağırlık kontrol noktasından önceki ve sonraki 1 yıllık eksik gönderimlerin müşteri şikâyetleri üzerine etkisi incelenmiştir. Çalışmada önerilen ağırlık kontrol noktasında 13.762 adet paletin belirlenen tolerans aralığının dışında olduğu tespit edilmiştir. Toplayıcılar tarafından gerekli kontroller yapılarak paletlerdeki hataların giderilmesi sağlanmıştır. Bu sistem ile müşteriye hatalı sevk edilen koli sayısında %92,9’luk, müşteri şikâyetlerinde ise %82,4’lük bir azalma sağlanmıştır. Gerçekleştirilen çalışma ile manuel sipariş toplamada ağırlık kontrol noktasının hata oranlarını ve müşteri şikâyetlerini azaltmada önemli katkılar sağladığı gözlenmiştir.
