Abstract

The purpose of lean thinking is to get rid of as much waste as possible. Eliminating wasteful activities such as transport, overproduction, waiting, defects, overprocessing, inventory and movement is one of the most important prerequisites in a successful company. This concept is an integral part of lean thinking, and it helps increase profitability. Material picking costs constitute approximately 55%-60% of the total costs related to warehouse operations [1]. The purpose of this article is to develop an information system that finds the shortest path for the responsible personnel to collect the materials required for production from the stock addresses in the warehouse, determines the number of picking boxes required for these materials, and provides the material sequences within the box (in-box sequences). With this developed information system, it will be possible to reduce material picking costs by eliminating wasteful activities such as transport, waiting and movement. The implementation of the developed information system is carried out in a company that produces electromechanical products in Ankara. With the Material Picking Information Systems (MPIS) presented in this article, up to 50% improvement has been achieved in terms of the distance and time spent by the personnel and the model has been validated.

Bir Üretim Sisteminde Depo Operasyonlarını İyileştirmeye Yönelik Bilgi Sistemi Önerisi

Abstract

Yalın düşüncenin amacı, mümkün olduğunca fazla israftan kurtulmaktır. Taşıma, aşırı üretim, bekleme, uygunsuz malzemeler, aşırı işleme, envanter ve hareket gibi katma değeri olmayan faaliyetleri ortadan kaldırmak, başarılı bir şirketin en önemli ön koşullarından biridir. Bu kavram, yalın düşüncenin ayrılmaz bir parçasıdır ve karlılığı artırmaya yardımcı olur. Malzeme toplama maliyetleri, depo operasyonları ile ilgili toplam maliyetlerin yaklaşık %55-60'ını oluşturmaktadır [1]. Bu makalenin amacı, sorumlu personelin üretim için gerekli malzemeleri depodaki stok adreslerinden toplaması için en kısa yolu bulan, bu malzemeler için gerekli olan toplama kutusu sayısını belirleyen ve kutu içindeki malzeme dizilimlerini sağlayan bir bilgi sistemi geliştirmektir. Geliştirilen bu bilgi sistemi ile taşıma, bekleme ve hareket gibi israflı faaliyetler ortadan kaldırılarak malzeme toplama maliyetlerinin düşürülmesi mümkün olacaktır. Geliştirilen bilgi sisteminin uygulaması Ankara'da elektromekanik ürünler üreten bir firmada gerçekleştirilmiştir. Bu yazıda sunulan Malzeme Toplama Bilgi Sistemleri (MPIS) ile personelin harcadığı mesafe ve zaman açısından %50'ye varan iyileştirme sağlanmış ve model valide edilmiştir.
