Abstract

Bu çalışmasının amacı, Yalın Altı Sigma araçlarını
kullanarak işletmenin tedarik zinciri süreçlerini gözden geçirmek ve mevcut
durumun yeterliliğini sorgulamaktır. İşletmenin tedarik zincirindeki maliyet
kalemleri finans sorumluları ile görüşülerek sigorta gideri, depo kirası,
finansman gideri ve evsafı bozulan ürünlerin maliyeti olarak sıralanmıştır. Stokta
kalma süresini ve stok miktarını azaltmak için TÖAİK (Tanımla, Ölç, Analiz Et,
İyileştir, Kontrol) tekniği kullanılmıştır. Tanımla aşamasında sistemin mevcut
durumu ortaya çıkarılarak SIPOC aracı ile süreç analiz edilmiş ve CTQ diagramı
çıkarılarak projenin metrikleri belirlenmiştir. Analiz aşamasında Kanban
yöntemi kullanılarak ortalama stok miktarı hesaplanmıştır. Daha sonra stok
miktarını arturan sebepler balık kılçığı ile analiz edilmiş, gerekli önlemler
alındıktan sonra yanetkilere karşı sorunların önlenmesi için kontrol
mekanizmaları kurulmuştur.

A SYSTEMATIC PERSPECTIVE ON SUPPLY CHAIN IMPROVEMENT BY USING LEAN SIX SIGMA AND AN IMPLEMENTATION AT A FERTILIZER COMPANY

Abstract

The purpose of this
study is to review the supply chain processes of an enterprise using Lean Six
Sigma tools and question the adequacy of the existing situation. The cost items
in the supply chain of the company are discussed with the finance officers and
listed as insurance expense, warehouse rent, financial expense and cost of
spoiled goods. The DMAIC (Define, Measure, Analyze,
Improve, Control) technique was used to decrease inventory time and inventory
amount. By defining the current situation of the system in the Define phase,
the process is analyzed with the SIPOC tool, and a CTQ diagram is created to
determine the project metrics. In the Analyze phase, the average inventory is
calculated using the Kanban method. Then, the reasons that increase the
inventory are analyzed by a fishbone diagram, and after the necessary
precautions, a control mechanism is established to prevent possible side effects
of the project.
